Types of DICOM image formats...

Question

I am aware of single frame and multi-frame dicom image files. I want to know about a cine dicom image, and are there any other dicom image formats.

Answer 1

As you mention, and Alon mentions in his comment, the DICOM file format supports single frame and multi-frame pixel data. A "Cine" DICOM file (typically an Ultrasound file) is simply a multi-frame DICOM file. The format for pixel data (singe vs. multi frame) is constrained by the Service Object Pair (SOP) Class that the DICOM file is implementing.

DICOM files can then be encoded in different uncompressed and compressed transfer syntaxes. for compressed transfer syntaxes, DICOM defines an encoding that allows both single and multi-frame pixel data. Among the supported transfer syntaxes are standard and lossless Jpeg, Jpeg-LS, Jpeg 2000, and MPEG. Note that the MPEG format is used for encoding video, and this is technically encoded as multi-frame pixel data.
