C.8.5.6.1.1 Image Type

For US Images, Image Type (0008,0008) is specified to be Type 2. The Defined Terms for Value 3 are:

ABDOMINAL BREAST CHEST
ENDOCAVITARY ENDORECTAL ENDOVAGINAL
EPICARDIAL FETAL HEART GYNECOLOGY
INTRACARDIAC INTRAOPERATIVE INTRAVASCULAR
MUSCULOSKELETAL NEONATAL HEAD OBSTETRICAL
OPHTHALMIC PEDIATRIC PELVIC
RETROPERITONEAL SCROTAL SMALL PARTS
TEE THYROID TRANSCRANIAL
TTE US BIOPSY VASCULAR

Value 4 is constructed as a modality bit map to allow for a description of multi-modality displays. In using this bit map, the sum of the values of the various modalities will unambiguously determine the constituent modalities.

0001 = 2D Imaging 0002 = M-Mode 0004 = CW Doppler
0008 = PW Doppler 0010 = Color Doppler 0020 = Color M-Mode
0040 = 3D Rendering 0100 = Color Power Mode 0200 = Tissue Characterization
0400 = Spatially-related frames

Notes: 1. All Values are hexadecimal encoded as a CS. See PS 3.5.

2. For example, Color Flow with CW spectral Doppler would have a value 4 = 0015. Note that no assumption should be made in Color Doppler or Color M-Mode regarding underlying B or M-Mode, respectively.

3. See Section A.59.1 for the relationship between a 3D volume set and the 3D Rendering, 3D MPR View, and Spatially-related frames image types. In the case of “3D Rendering”, Derivation Code Sequence (0008,9215) should be used to describe the specific type of 3D rendering (volume rendering, surface rendering, multiplanar reformatting, etc.).
