In magnetic resonance imaging with two series having same

FrameofReferenceUID, how can I create SCOUT/LOCALIZER lines? I mean, I have a sagital image and 20 axial images and I want to draw scout lines in sagital image. Sagital image and axial images have different ImageOrientationPatient.

I think I do understand what you are trying to achieve and can even see the point in why you would want to do that. :-) First have a look at the dicominfo function to retrieve some relevant parameters:

dinfo=dicominfo('myfile.dcm');
dinfo.ImagePositionPatient; % Left bottom corner
dinfo.PixelSpacing(1) * dinfo.Columns; % 1st dimension, etc
dinfo.ImageOrientationPatient; % Orientation vector

Using the above values from both your scout and sagital images you can calculate the intersection of the two. This is actually the complicated part I cannot cook up in a minute.

I also suggest to have a real good look at the file exchange because I would expect something like what you are looking for to be present already.
