Hi Shu,

map3d is a good option for the functionality you described, if you have surface data.  You can save out the mesh and the data seperately from scriun in the matlab format and it will load into map3d.  

There is a new plotting module in SCIRun, that is currently not in the release (you would have to build from source), but will be soon  I could send a preliminary build that includes it if needed.  This module would allow line plotting a matrix. You could use this with a GenerateSinglePointProbe to move around a point and map the node index nearest to it. Then use GetMatrixSlce to select the appropriate row of your data matrix.  You wouldn’t be able to select points, but you could move the widget around to get signals from various areas.  I can provide more details if needed.

cheers,
Jess

Petar, Shu h,

@Petar, EGM == electrogram, a name for an electrical signal waveform recorded on the heart surface (to distinguish from ECG on body surface)

@Shu, I suggest you try a different CIBC tool, map3d, for what you want to do -- it's a wonderful tool (IMO) for exactly what you describe, and also available from our website.  Several others on this list can advise you about the best ways to get data / geometry from / to SCIRun / map3d ..

best,

Dana

Hi Shu,

what is EGM, maybe you mean EMG?

Dear SCIRun team,

This is Shu Meng, a postdoctoral research fellow from Auckland Bioengineering Institute working on forward/inverse problem. SCIRun is a very convenient and powerful software to solve my problems and I have been using it for few years.

Here I have a question, I am just wondering if SCIRun has some functions like this: can I click on some desired electrode and then EGMs can be visualized. The chosen signal analysis are color-coded and projected onto the atrial geometry, so that anatomy and measurement results can easily be related.

Maybe I ask to much ;)

Thank you and looking forward to your reply.

Shu
