Abstract
A system(s), a computer-implemented method(s) and/or computer executable instructions encoded on a computer readable medium(s) obtains, for a scan series for a subject that includes arms of the subject at different positions relative to the subject, a scout image for the subject, removing the arms of the subject from the scout image, designating the scout image with the arms of the subject removed as a reference image for X-ray source current modulation for the scan series, and utilizes the designated scout image for X-ray source current modulation for the scan series.
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:
- obtain a scout image for a scan series that includes at least two scan groups, wherein the scout image includes arms of a subject either up above shoulders of the subject and down by sides of the subject, a first group of the at least two groups includes the arms of the subject up above the shoulders of the subject, and a second group of the at least two groups includes the arms of the subject down by the sides of the subject;
- identify the arms of the subject in the scout image;
- remove the identified arms of the subject from the scout image thereby generating a new scout image without arms of the subject;
- and
- designate the new scout image as a reference image for X-ray source current modulation for the first group and for X-ray source current modulation for the second group;
- and
- command the X-ray controller to utilize the new scout image as the reference image for X-ray source current modulation for the first group of the scan series and as the reference image for X-ray source current modulation for the second group of the scan series.
A computer-implemented method, comprising:
- obtaining a scout image for a scan series that includes at least two scan groups, wherein the scout image includes arms of a subject either up above shoulders of the subject and down at a side of the subject, a first group of the at least two scan groups includes the arms of the subject up above the shoulders of the subject, and a second group of the at least two scan groups includes the arms of the subject down by the side of the subject;
- identifying the arms of the subject in the scout image;
- removing the identified arms of the subject from the scout image thereby generating a new scout image without arms of the subject;
- and
- designating the new scout image as a reference image for X-ray source current modulation for the first group and as a reference image for X-ray source current modulation for the second group.
A computer readable medium encoded with computer executable instructions, which when executed by a processor, causes the processor to:
- obtain a scout image for a scan series that includes at least two scan groups, wherein the scout image includes arms of a subject either up above shoulders of the subject and down by sides of the subject, a first group of the at least two scan groups includes the arms of the subject up above the shoulders of the subject, and a second group of the at least two scan groups includes the arms of the subject down by the sides of the subject;
- identify the arms of the subject in the scout image;
- remove the identified arms of the subject from the scout image thereby generating a new scout image without arms of the subject;
- and
- designate the new scout image as a reference image for X-ray source current modulation for the first group and as a reference image for X-ray source current modulation for the second group.
