Issues with multi-frame dicom files

[pritamrungta]

Describe the bug Trying to load a multi-frame dicom file. Getting incorrect image_shape (just width and height) and is_multi_frame=False.

To Reproduce Steps to reproduce the behavior:

1. parse a multi frame dicom file
2. can't see information regarding the frames

Expected behavior Should be able to read the file as multi frame and get all individual frames' headers + pixel data as well.

Screenshots NA

Desktop (please complete the following information):

• OS: MacOS Sonoma (M1 chip)
• Browser: NA
• Version: 14.4.1

Smartphone (please complete the following information):

• Device: NA
• OS: NA
• Browser: NA
• Version: NA

Additional context

Attached a synthetic file for reference. multi-frame.dcm.zip

pydicom seems to correctly read all the frames. So, for the above file:

• pydicom.dcmread('multi-frame.dcm').pixel_array.shape = (2, 3, 4)
• dicom_parser.Image('multi-frame.dcm').image_shape = (3, 4)

Is this already supported through a different method which I've overlooked by chance?
