How to read a single frame from the Multi frame Dicom file

[AIVinci]

I want to display single frame from multi frame Dicom file. It is huge file (1.4 gb) creating memory error if read as whole.The file is compressed in Jpeg Lossy format.

This has been brought up before, but no solution in pydicom yet - see e.g. #1243, #1035.

@Alvinci we are currently implementing a high-level interface for reading frames of a multi-frame Part10 file (see highdicom PR). We hope to get all the low-level functions ultimately into the pydicom pixel data handlers.

@Alvinci this is now available in highdicom (see highdicom.io.ImageFileReader).

@hackermd Hi, I try to use highdicom. io. ImageFileReader to solve the problem of large file(ultrasound dicom 300+m) read slowly. When I use the example code, this error occurs: 'FileDataset' object has no attribute 'ICCProfile'

from highdicom.io import ImageFileReader
with ImageFileReader(r'C:\Users\UAX\Desktop\test\300m\1.dcm') as image:
print(image.metadata)
for i in range(image.number_of_frames):
frame = image.read_frame(i)
print(frame.shape)

Do you have similar problems? How can I solve it? Thank you~

@jnumingdeli we are currently working on including the ImageFileReader in pydicom via #1447. We have removed the image color management from the class, so the error you described should no longer occur.

@hackermd Thank you very much~ Will this class be added to the next new version of pydicom? When will this feature be available?

[hackermd]

I defer to @darcymason regarding release milestones and timeline.

Hi, are there any updates on this feature? I am working on a problem that requires the same.

@elams18 The class is currently available in highdicom: https://highdicom.readthedocs.io/en/latest/package.html#highdicom.io.ImageFileReader
