C.8.15.3.2.1 Acquisition Type

Acquisition Type (0018,9302) has the following Defined Terms:

SEQUENCED identifies that the acquisition was performed by acquiring single or multi detector data while rotating the source about the gantry while the table is not moving. Additional slices are acquired by incrementing the table position and again rotating the source about the gantry while the table is not moving.

SPIRAL identifies that the acquisition was performed by acquiring data while rotating the source about the gantry while continuously moving the table.

CONSTANT_ANGLE identifies that the acquisition was performed by holding the source at a constant angle and moving the table to obtain a projection image (e.g., a localizer image).

STATIONARY identifies that the acquisition was performed by holding the table at a constant position and acquiring multiple slices over time at the same location.

FREE identifies that the acquisition was performed while rotating the source about the gantry while the table movement is under direct control of a human operator or under the control of an analysis application (e.g., fluoroscopic image).
