Abstract
Methods and systems are provided for estimating patient structure prior to a scan by a medical imaging system. As one example, a method may include acquiring depth images of a patient positioned on a table of the medical imaging system, correcting the depth images based on histogram data from the depth images, and extracting a three-dimensional structure of the patient based on the corrected depth images.
Claims20
A method for a medical imaging system, comprising:
- acquiring depth images of a patient positioned on a table of the medical imaging system via a depth camera;
- correcting the depth images based on histogram data from the depth images;
- and
- extracting a three-dimensional structure of the patient based on the corrected depth images.

A method for a medical imaging system, comprising:
- adjusting an exposure mode and gain of a depth camera positioned to acquire images of a patient exam scene based on histogram data from the acquired images;
- and
- determining a three-dimensional structure of a patient in the patient exam scene based on the acquired images.
A system, comprising
- a rotatable gantry having a bore centrally disposed therein;
- a table movable within the bore and configured to position a subject for image data acquisition within the bore;
- a camera positioned to acquire images of the subject on the table prior to entering the bore;
- and
- a computing device storing executable instructions in non-transitory memory that, when executed, cause the computing device to:
- receive images of the subject on the table from the camera;
- identify a lighting condition in the received images based on histogram data from the received images;
- correct the received images based on the identified lighting condition;
- identify a pose of the subject on the table based on the corrected images;
- and
- output an alert responsive to the pose of the subject deviating from a desired pose for the image data acquisition.
