How can I save the output figure into an image file?

recon_img = senserecon(aliased_img, sen_map,reduc, fi_matrix);
figure;imshow(abs(recon_img),[0 0.000005]);title('sense recon');

After this line of code the output image shows. Now, I want to export this output figure into another image file.

recon_img = senserecon(aliased_img, sen_map,reduc, fi_matrix);
figure;imshow(abs(recon_img),[0 0.000005]);title('sense recon');
print(gcf,'-dpng','-r200','sense_recon')

The image saves with the title. Is there any way to remove the title? and there are several iterations in the program. So, there are multiple output images? How can I save all using a loop?

A easy way is to use exportgraphics, introduced in R2020a:

f = figure;
imshow(...);
exportgraphics(f, 'filename.jpg'); % or .png or whatever format you want (see documentation)
