Abstract
A system(s), a computer-implemented method(s) and/or computer executable instructions encoded on a computer readable medium(s) receives a current position of arms of a subject for a group of a scan series, automatically identifies a scout image from a set of scout images with images of the subject with arms in different positions relative to the subject in which arms of the subject are at a position relative to the subject that corresponds to the current position of the arms of the subject, and utilizes the identified scout image for X-ray source current modulation for the group.
Claims20
A computed tomography imaging system, comprising:
- a rotating frame configured to rotate about a rotational axis;
- an X-ray source disposed on the rotating frame and configured to emit X-ray radiation that traverses an examination region;
- an X-ray controller configured to control the X-ray source;
- a subject/object support configured to support a subject or object in the examination region;
- a console, including:
- a computer readable medium configured to store instructions;
- and
- a processor configured to execute the instructions, wherein the instructions cause the processor to:
- receive a current position of arms of a subject for a first group of a scan series, wherein the current position is a first position of two positions, either the arms are up above shoulders of the subject or the arms are down by sides of the subject;
- automatically identify a scout image for the subject in which a position of the arms of the subject in the scout image matches the current position of the arms of the subject,
- wherein the scout image is identified from a set of scout images that includes a scout image with the position of the arms above shoulders of the subject and a scout image with the position of the arms down by the sides of the subject;
- and
- command the X-ray controller to utilize the identified scout image as a reference image for X-ray source current modulation for the first group of the scan series.
A computer-implemented method, comprising:
- receiving a current position of arms of a subject for a first group of a scan series, wherein the current position is a first position of two positions, either the arms are up above shoulders of the subject or the arms are down by sides of the subject;
- automatically identifying a scout image for the subject in which a position of the arms of the subject in the scout image matches the current position of the arms of the subject,
- wherein the scout image is identified from a set of scout images that includes a scout image with the position of the arms above shoulders of the subject and a scout image with the position of the arms down by sides of the subject;
- and
- utilizing the identified scout image as a reference image for X-ray source current modulation for the first group.
A computer readable medium encoded with computer executable instructions, which when executed by a processor, causes the processor to:
- receive a current position of arms of a subject for a first group of a series, wherein the current position is a first position of two positions, either the arms are up above shoulders of the subject or the arms are down by sides of the subject for a first group of the series;
- automatically identify a scout image for the subject in which a position of the arms of the subject in the scout image matches the current position of the arms of the subject,
- wherein the scout image is identified from a set of scout images that includes a scout image with the position of the arms above shoulders of the subject and a scout image with the position of the arms down by the sides of the subject;
- and
- utilize the identified scout image as a reference image for X-ray source current modulation for the first group.
