• 2016-11-15 10:28:17> @U07UEJC2H: Le problème de la sonde ATL c'est que c'est une tête circulaire avec trois transducteur pas très pratique à utiliser. Tu ne peux pas extraire un transducteur pour faire ton propre montage.
• 2016-11-15 12:43:32> @U0AAL4W13: C'est vrai que les 3 piezos insérés dans la tête sont indissociables, ensuite il doit être possible de les réinsérer dans un système pour les driver (la tête à un engrenage fixé et un systeme de transmission électrique sans contact). En tout cas, en l'absence de l'achat d'un transducteur auprès d'un fabricant, c'est la meilleure option (autres sondes sont plus ou moins faciles à démonter, et la y'a 3 piezos pour le prix d'un ;) ). My two cents.
• 2016-11-15 12:43:47> @U0AAL4W13: Le top reste des piezos chez un supplier c'est clair :)
• 2016-11-15 15:00:28> @U0B47KC3S: <#C07NJQ6LE> proceed in english :wink:
• 2016-11-15 15:04:42> @U0AAL4W13: Shoot true
• 2016-11-15 15:07:59> @U0AAL4W13: Anyhow, ideal remains piezo transducers, with know frequency, specs, and easily connectable. In this respect, supplier made transducers are awesome. In a second position, refurbished atl probes have an advantage of being similar to monoelement equipment, BNC connection so can't be more standard, and piezo specs are known.
• 2016-11-15 15:09:52> @U0AAL4W13: A challenge still remains though: you can image by powering the probe motor and the transducer, but with a more work, you can hack the control position system of the probe to know exactly what line you're imaging, and introduce a motor feedback control
• 2016-11-15 15:11:04> @U0AAL4W13: With this element, one is able to have a probe fully functional - and also directly usable on voluntary testers // pieces of steak // tofu, since the casing of the probe make it easy to use (at the opposite of a transducer in water)
• 2016-11-15 15:11:36> @U0AAL4W13: Depends on where you focus is, if you want to play with piezos and mechanics, you won't be interest in all in one solutions
• 2016-11-15 15:12:30> @U0AAL4W13: But if you want to play downstream with electronic and signal processing, and don't want to muck with the piezos and probe, that's an interesting option :)

• 2016-11-23 14:11:18> @U07UEJC2H: And what do you chose to have a transducer? I still think doppler probe is the better choice.

• 2016-11-23 14:11:56> @U0B47KC3S: Here’s the doc principles :
• 2016-11-23 14:12:02> @U0B47KC3S: each configuration, corresponds to modules and daughter-boards, each module or daughter-board implements interfaces which describes describes an electrical signal or a specific data structure (reactions: @U04DFTZ7D,@U32FZ0QLX,@U32FZ0QLX)
• 2016-11-23 14:48:56> @U0AAL4W13: Superb ! Two questions to complete: are the tgc and the pulses modules evaluation boards? And are there instructions for an error-proof soldering of the daughter cards?
• 2016-11-23 15:14:17> @U07UEJC2H: <@U336DPZV4>, the traking number is RK031315319FR
• 2016-11-23 15:16:35> @U07UEJC2H: <@U0AAL4W13>, the pulser has two versions, one with evaluation kit and one home made version. The TGC has only evaluation kit version for the moment, other version will be on tests soon
• 2016-11-23 15:18:39> @U07UEJC2H: DB_tr_switch_tgc as a security with a jumper and a test point to be sure that the -100V pulse is clipped before tracking it to the TGC, the other daughter boards don't need it

• 2016-11-23 22:44:01> @U2V0F9YAK: <@U07UEJC2H> Concerning our project we ordered and received a few days ago a series of electronic elements such as the pulser, the switch and the acquisition card. For the probe, we will use the ATL one proposed by Luc which will be sent soon. In case of problem we might be interested in one of your set
• 2016-11-24 03:27:53> @U32FZ0QLX: Hi all, one questions, in the electronics, there is a series of modules such as filters, amplifiers and so on, why the design with more pins if it isn't necessary?, for example in the case of the filters, standardization?
• 2016-11-24 09:22:45> @U07UEJC2H: <@U32FZ0QLX>, I not sure what you want to point. Is it about the 19 track connector?
• 2016-11-24 16:37:49> @U32FZ0QLX: <@U32FZ0QLX>
• 2016-11-24 16:45:15> @U07UEJC2H: Indeed, the boards do not use all the tracks (this board use only 3 tracks), but for homogeneity and simplicity (you don't have to check where to plug the board) we use the same connector for all the daughter boards.
• 2016-11-24 21:18:36> @U32FZ0QLX: Hi <@U07UEJC2H> very thanks

• 2016-12-17 15:12:03> @U0AAL4W13: Imagine raw images of 128x512 to 256x1024, 12 bits, at a framerate of 20fps (roughly)
• 2016-12-17 15:18:37> @U38HVMZ6K: Thx. Was to make my mind on the order of magnitude so 256x1024x12x20 bits/sec ~ 63Mbits/sec

• 2016-12-17 15:32:21> @U0AAL4W13: Au lieu de 1024pts tu mets 150us d'acquisition, ensuite ça dépend de ton adc (150x30 à 30msps -- ça dépend aussi après si tu transmets ton plein signal ou un signal tronqué dans l'espace de fourrier)

• 2016-12-20 21:30:30> @U0AAL4W13: <@U394HRZ1B> : the name MSLPU39 shows that it's also a uprobe-20, the last born of the uprobe series (after the 1 and the 2). That being said, to hack it, I'd say it depends on the artist, if she has the skills to hack it. Anyhow, it seems the probe comes with a PC software :smiley:

• 2017-02-14 09:59:11> @U0B47KC3S: you are free not to consider the echOpen association, which however brought a lot of things use of the space and materials to do numerous experiments, valuable conversations with experts (Cap*) or Farad, Jérôme..., community sollicited as reviewing your paper :wink:
• 2017-02-14 09:59:19> @U0B47KC3S: But, it is a good and ethic pratice in research to cite people the following way : some guys (as the much much appreciated) Farad or others who did contributions less important than yours or minor, as second, third authors, etc... and to put yourself to the front as first author
• 2017-02-14 09:59:31> @U0B47KC3S: Last point, a "Competing Interest" section correponds in research papers is used to declare the structures with whom you have some personal interests. So here, the formulation sounds quite weird for the association :thinking_face:
• 2017-02-14 09:59:45> @U0B47KC3S: when you have no competing interest then the pratcice is to declare "no competing interests were disclosed”. As simply as that !
• 2017-02-14 11:22:59> @U0AAL4W13: yup <@U0B47KC3S> :) there were actually no major inputs (aparts from quick chats) with other people so I can't add one as co-author without adding the whole community :) - I do recognize the value of discussion and put these people in acknowledgements :)
• 2017-02-14 11:25:36> @U0AAL4W13: for the disclaimer, that's the one we agreed upon this summer, but since we have been working on this IP understanding and since some modules have been added to the community github, we can review/update it :)
• 2017-02-14 11:41:38> @U0B47KC3S: thanks for response. Yes, the disclaimer was related to a very different context. As said, the simplest is to declare no competing interest :wink: I don’t know where you're going to submit but every peer reviewed journals has its own formalism (they always provide author guide) and what is widely in use is to declare some formula such as “no competing interests were disclosed”.
• 2017-02-14 12:13:49> @U07UEJC2H: <@U0AAL4W13>, I can't see your community logic... In one hand you say "the echOpen association having no involvement with this work" and in the over hand you ask for review... It is not a give and take relationship
• 2017-02-14 12:15:59> @U0AAL4W13: true
• 2017-02-14 12:16:11> @U0AAL4W13: but I have put names in acknowledgements
• 2017-02-14 12:16:54> @U0AAL4W13: apart from review and discussions - it's very true that if review is done, I'll gladly indicate it :)
• 2017-02-14 12:19:02> @U0AAL4W13: it's also a fact that major works in this fork were done in parallel of the association :)
• 2017-02-14 12:27:18> @U0AAL4W13: as proposed by <@U0B47KC3S> - will change the competing interest sentence :)
• 2017-02-14 12:44:11> @U2PFHNN3C: sorry, I might come late in the discussion (tough to be in Munich and keep up with all the exchanges). Nice paper <@U0AAL4W13>, I’ll read it carefully for sure, but not for review, rather for learning :smile:. One point though, I skimmed through it quickly and I think you should mention that it’s an echOpen fork, regardless of the contributions one or the other brought in. It’s just the way the open source communities work: when it comes to forks, keep track of the lineage. Just a cold opinion, FWIW.
• 2017-02-14 12:49:51> @U07UEJC2H: <@U0AAL4W13>, just a reminder: - global architecture of "your" device commes from echopen - most of the key components used commes from echopen - thirst phantom you used commes from echopen - "professional" echographic image of this phantom commes from echopen echograph - second phantom you used commes from components you took in echopen lab
• 2017-02-14 12:51:16> @U0AAL4W13: not true: architecture implementation stems from murgen, an original work starting from a capTech when we decided to explore different paths
• 2017-02-14 12:53:17> @U0AAL4W13: key components (pulser, hv ic, tgc) have been identified at murgen stage ( and documented, dated in ) and implemented in murgen before the current modules were designed .
• 2017-02-14 12:53:28> @U0AAL4W13: agree for the phantoms!
• 2017-02-14 12:53:58> @U0AAL4W13: agree for the image from the profesional image from the echograph
• 2017-02-14 12:56:23> @U0B47KC3S: hi there ! this is a friendly smiley :grinning: indeed <@U07UEJC2H> there were bunch of works coming from several parts and sure murgen is also great work :wink:
• 2017-02-14 12:56:26> @U0B47KC3S: <@U0AAL4W13> you are the author, you are sovereign on how to present it !
• 2017-02-14 12:56:33> @U0B47KC3S: Anyway, so Newton said “Nous sommes des nains juchés sur des épaules de géants”
• 2017-02-14 12:56:39> @U0B47KC3S: which google translates into “We are dwarfs perched on the shoulders of giants” This is a community ethics ! (reactions: @U0AAL4W13,@U07UEJC2H)
• 2017-02-14 12:58:44> @U0AAL4W13: as said earlier, I'll be glad to reflect the actual collaboration level with the community and association support - and will be happy to adjust a disclaimer which dates a bit. (reactions: @U0B47KC3S)
• 2017-02-14 13:01:45> @U0AAL4W13: at the same time, it's also respectful for all to recognize the original works who have been done by all :) this work is fully original, and predates choices done the association (the documentation is there :) ). per se, it's not a fork on technical bases, rather a fork on "open source ultrasound tools" :)
• 2017-02-14 14:30:21> @U07UEJC2H: Technically it's not a fork? Be coherent with yourself, you say in your github that (https://github.com/kelu124/murgen-dev-kit/blob/master/hardware/Readme.md):"This project is born from a fork from the echOpen project"
• 2017-02-14 14:35:41> @U0AAL4W13: not a technical fork - there was no original material content to be forked - it's a conceptual fork ;)

Je voudrais rappeler à <@U0AAL4W13> que je lui ai prêté pendant au moins 15j mon BitScope et aussi que c'est moi qui lui ai montré qu'il avait oublié de brancher la masse de la sonde de l'oscillo pendant une série d'essais qui ne donnait rien et je constate que qu'il n'en est aucunement fait mention dans le papier. Luc t’es vraiment pas très gentil ! Vous l’avez compris, je trouve l’échange précédent assez déplorable et bien loin des valeurs d’échange, de partage et de collaboration qui sont la vraie valeur de notre association. Et je tiens juste à rappeler aussi que dans cette affaire nous n’avons absolument rien inventé et que nous sommes juste tous en train de « forker » (avant on disait pomper) des technos qui datent du siècle dernier et que l’on trouve détaillées dans n’importe quel manuel du « petit échographiste ».
• 2017-03-03 14:34:51> @U0GMX7QUB: PS: Sorry for the french. But Google is your friend ... and in Google-English that gives : After the fight (I'm not very "Slack" :disappointed:) ... I would like to remind you that I lent him my BitScope for at least 15 days and also that it was I who showed him that he had forgotten to connect the mass of the oscillo probe during a series of tests Which gave nothing and I note that there is no mention of it in the paper. Luc you really are not very nice! You have understood, I find the previous exchange rather deplorable and far from the values of exchange, sharing and collaboration that are the true value of our association. And I just want to remind you that in this case we have absolutely nothing invented and that we are just all in the process of "forker" (before we said pumping) technos that date from the last century and that we find detailed In any manual of the "small sonographer". :grinning:

• 2017-03-12 23:37:57> @U0B47KC3S: it’s so cool to see the work of a remote echOpen path :wink: hope to hear about you soon !
• 2017-03-12 23:42:54> @U2UU194RZ: we will have to stop our project in 2 weeks, until then, we are writing a report and making some advances, but we cannot do much more :confused: we will post everything on our site when it will be over for us. Other students will work on this project the next year :slightly_smiling_face:
• 2017-03-12 23:55:23> @U0B47KC3S: <@U2UU194RZ> I heard there is a fablab in ULB, maybe there is a way to connect echOpen with this community and push forward your work. Do you know about it ?
• 2017-03-12 23:58:42> @U2UU194RZ: We heard about it, I'll talk with the others and Olivier Debeir of a possible connection
• 2017-03-13 00:06:12> @U0B47KC3S: great :wink:
• 2017-03-27 12:06:22> @U07UEJC2H: <@U07UEJC2H> and commented: Hi all, I made some tests to look at the improvement of the kit last week. On this image one can see a line where there is a plate, green is the result we had on October and blue today with numeric envelope detection
• 2017-03-27 12:06:44> @U07UEJC2H: <@U07UEJC2H> and commented: Here is a zoom on the signal
• 2017-03-27 12:08:47> @U07UEJC2H: Before we had a signal on noise ratio (SNR) around 28 dB, now it's around 48 dB, so we have gain 20 dB. In other words it's 100 times beter
• 2017-03-27 12:09:37> @U07UEJC2H: Moreover, the envelope is better
• 2017-03-27 12:23:19> @U3GHS132Q: Nice one :slightly_smiling_face: What did you do to have those improvements ?
• 2017-03-27 12:36:07> @U0B47KC3S: over Great news <@U07UEJC2H> !!! :upside_down_face: :clap::stuck_out_tongue_closed_eyes: :rocket:

• 2017-03-27 12:47:23> @U07UEJC2H: <@U3GHS132Q>, by changing TCP "transfer method" to send 16 bits buffer by aliasing the pointer buffer and numerical envelope detection plus numeric pass band filter
• 2017-03-27 12:51:10> @U3GQS8JTZ: <@U3GQS8JTZ> has left the channel
• 2017-03-27 12:51:17> @U0AAL4W13: Excellent! Is that possible to have the same processing (without the tcp part maybe?) on the previous "hand" images to see the difference?
• 2017-03-27 18:21:03> @U3GHS132Q: <@U07UEJC2H> By aliasing did you mean pointer aliasing https://en.wikipedia.org/wiki/Pointer_aliasing ?
• 2017-03-27 18:36:09> @U07UEJC2H: <@U3GHS132Q>, yep, it is that
• 2017-03-28 16:10:13> @U3GHS132Q: <@U07UEJC2H> I do not see how you can improve performance with pointer aliasing, do you upload your code somewhere ?
• 2017-03-28 17:13:12> @U07UEJC2H: With pointer aliasing we can send 16 bits precision measured signal, before it was only 8 bits precision
• 2017-03-28 18:16:29> @U0AAL4W13: Hey <@U07UEJC2H> I'm interested about the changes as well !
• 2017-03-28 18:17:42> @U0AAL4W13: Is the difference coming from the 3 elements you're mentioning - or just the enveloppe detection digital processing?
• 2017-03-28 18:19:48> @U0AAL4W13: And similarly to <@U3GHS132Q>, can you share the code and data? Would be great for the <#C1G7T0PNX> meeting :)
• 2017-03-29 09:56:11> @U07UEJC2H: The difference came mainly from increasing precision of sent data, secondly by numerical filter. Numerical envelope detection improve envelope quality and a little bit the maximum of the envelope (due to quality improvement) (reactions: @U37GZRZU6)
• 2017-03-29 10:36:07> @U0AAL4W13: Excellent! I assume that the green line is the data acquired, artificially degraded from 16 bit to 8 bits? In any case, v. interesting food for thoughts for <#C1G7T0PNX> team :) (reactions: @U37GZRZU6)
• 2017-03-29 10:49:35> @U07UEJC2H: Nop, it is exactly the experience, juste switching form one configuration to the other (it is an option in the soft used in the RedPitaya), no numerical treatment.
• 2017-03-29 21:44:38> @U0AAL4W13: To test the kit with an ATL probe, details in terms of connections are here: https://kelu124.gitbooks.io/echomods/content/Chapter2/retroATL3.html ping <@U0B47KC3S>

• 2017-05-11 09:22:48> @U0AAL4W13: What I would recommend is rather to order 1 set at first -- to do the tests and check all works. It'd be sad to have an error repeated on the 10 boards (and that's happening more often than not, isn't it <@U0HF2S3QX> ? ;) )
