What is the MultiFrame image in DICOM. How multiframe is different from having multiple images in a single series?

A multiframe object consists of a single package, i.e. one image header that contains the demographic and other related information, followed by the pixel data for all image frames. The relationships between the individual frames in a multiframe object needs to be identified in the header.
The product automatically shoots multiple images continuously, combines them, reduces the noise, and records them as one image. With multi frame noise reduction, you can select larger ISO numbers than the maximum ISO sensitivity. The image recorded is one combined image.
A DICOM image file is an outcome of the Digital Imaging and Communications in Medicine standard. Specifically, image files that are compliant with part 10 of the DICOM standard are generally referred to as “DICOM format files” or simply “DICOM files” and are represented as “.dcm.”[2]
The DICOM image slices are stacked to build a 3D representation of the brain MRI image. Therefore, the resolution of the 3D image includes the number of slices ( ) besides and when acquiring the MRI scans.
A multi-frame image is typically a more compact representation of a multi-image (single-frame) series. In a single-frame image series, you would need to repeat the same header data (patient information, image properties etc.) in every image; in a multi-frame image the header data is given once.
Multi-frame images inevitably have some limitations in relation to single-frame image series; in particular, all frames in the multi-frame image would need to have the same size, orientation, etc.
Multi-frame images have historically also not been as widely supported by DICOM viewers, PACS systems etc. as single-frame images, although I believe that this situation is improved nowadays.
