I need help! How to plot B1 field with the help of this code?

Hi,

• I have simulated RF coil and generated B1 field with the help of a commercial software and now I want to visualize the same with the help of a matlab. But, I am not able to do so.
• The output of the commercial software is stored in bin file so I have attached it here.
• I have attached the code in m file
• I have attached the figure from the commercial software that I get of B1 field.
• I have attached the figure that I am getting in Matlab by using and modifying this code.
• I have attached the workspace window here which I believe shows the error. It shows vector img size is 1*362 double while all other input is 313*362 double. I am not sure but may be this is the problem which results in the output image.

Any help is appreciated. I am really stuck at this. Thanks in advance!

any comments ?

What about using the debugger to step through your code line by line and check, where the unexpected dimensions come from?

Thanks Jan Simon for taking your time to comment. I found out that taking rms resulted in that dimension. By removing rms, I get 313x362 double as expected. Still, I am not able to figure out why there is variation in the output image with respect to the image I get from commercial software. So, far I got this image after optimizing. Also, would it be possible to make this image more smoother? There are some straight lines which comes in the image. I have attached the optimized code with this comment.
