1. A medical imaging system, comprising:
a computed tomography (CT) imaging system, comprising:
a gantry having a bore, rotatable about an axis of rotation;
a table configured to move a subject to be imaged into and out of the bore of the gantry;
a radiation source mounted on the gantry and configured to emit an X-ray beam; and
a detector configured to detect the X-ray beam emitted by the radiation source;
a light detection and ranging (LiDAR) scanning system physically coupled to the CT imaging system, wherein the LiDAR scanning system is configured to acquire data of the subject from different angular positions relative to the axis of rotation; and
processing circuitry configured to receive the data acquired with the LiDAR scanning system, to generate a three-dimensional (3D) measurement of the subject, and to utilize the 3D measurement in a subsequent workflow process for a CT scan of the subject with the CT imaging system, wherein the CT imaging system comprises a gantry housing, wherein the LiDAR scanning system comprises one or more LiDAR scanners configured to acquire the data, and the one or more LiDAR scanners are disposed within the gantry housing, and wherein the gantry housing comprises both a scan window and a LiDAR window disposed about the bore, and wherein the one or more LiDAR scanners are disposed beneath the LiDAR window between the scan window and a side of the gantry housing adjacent the table.
