Hi all,

i want to use multibrandread function, but got error. this is my dicom image 128ASTITR2SUB8.dcm

which is my image have Rows=130, Columss=130, numberofFrames =90

this is my coding.

SPECTinfo = dicominfo('128ASTITR2SUB8.dcm');
fixedVolume  = multibandread('128ASTITR2SUB8.dcm',...
                            [SPECTinfo.Rows, SPECTinfo.Columns, SPECTinfo.NumberOfFrames],...
                            'uint16=>single', 0, 'bsq', 'ieee-be' ); 

but i got error

Index exceeds the number of array elements (15).

Error in multibandread>readDiskFile (line 269)
        im(:,destNdx(2),destNdx(3)) = data(srcNdx{1}-kStart+1);

Error in multibandread (line 165)
        im = readDiskFile(filename, info, ndx, readOrder);
        

What does means by Index exceeds the number of array elements (15).????

Anyone can help me?

dcm files are binary files with structured binary segments. https://docs.fileformat.com/image/dcm/ . The first 128 bytes are reserved for comments, or binary 0 if unused. You are reading starting from byte 0, so you are reading the comments as-if they are data.

The easiest explanation for that error would be if SPECTinfo.Rows, SPECTinfo.Columns, and SPECTinfo.NumberOfFrames are all non-scalar.
