Startup problems

[saltobelli]

Dear Dr. Amrein,

I would like to use your software to design some imaging gradients. I downloaded the zip, extracted it and set the top level directory and subdirectories on the MATLAB path. I set the current directory to Examples. The ygradient_coil example complained that the "iteration_num_stream_function_refinement" parameter was invalid. I couldn't see it in the parse_input source so I removed it in the example code, which ran and produced a reasonable looking coil. So that's a small issue.

The coil is larger than I need, so I made a smaller cylinder stl in blender. I'm still working on getting the script to run. I want eventually to use the output of your software to produce a Gerber file, manufacture a flexible circuit 'board', and wrap that on a cylindrical form. Do you think the software is suitable for this application? Do you have any words of wisdom about how to do this?

Thanks very much.

Hi Saltobelli,

With the latest version of CoilGen you do not need stl files for cylinders. You can specify you cylindrical mesh with the input parameter:

**'cylinder_mesh_parameter_list',[0.4913 0.154 50 50 0 1 0 pi/2],... % cylinder_height[in m], cylinder_radius[in m], num_circular_divisions,  num_longitudinal_divisions, rotation_vector: x,y,z, and  rotation_angle [radian]**

remove any stl input defintion for current carrying surface form the inputs.

The tool is very appropriate for your needs. we already succesfully generated pcbs with it.

I would like to know more about your procet. what is your name? is it commercial or open source/academic?

Best Philipp

Hi, Philipp,

My name is Stephen Altobelli, I go by Steve. I'm a Scientist at a small company in Albuquerque, New Mexico, USA. I've been working with MRI/NMR since the late '80's, imaging flows and other non-medical things.

We are building a low field (variable, up to 100 MHz) imaging system which must accommodate potted (about 20 cm in diameter) plants. Our collaborators at Texas A&M will use it in a greenhouse to image roots. The project is funded by the US ARPA-E. So it's a hybrid commercial/academic project.

We have built a few systems over the years, laying out the gradients with wires using classic designs, like those described by B. Suits. We want to build a second copy of this system for our own use, perhaps also a few more similar systems for other institutions. So I want to try a more modern and reproducible technique, hence my interest in your software.

I'm out of the lab for a few days, when I get back I will make the change you suggest. May I contact you further?

Thanks for you quick and helpful response.

Steve
