Abstract
A method includes obtaining an image of a region of interest of a subject, wherein the image is generated with image data produced by an imaging system used to scan the subject, obtaining a signal indicative of a physiological state of the subject before the scan, and displaying both the image and data indicative of the physiological state. In another aspect, a method includes correcting, via a processor, a tracer uptake value for a target region of interest based on a tracer uptake correction factor.
Claims36
A method, comprising:
- obtaining an image of a region of interest of a subject, wherein the image is generated with image data produced by an imaging system used to scan the subject;
- obtaining a signal indicative of a physiological state of the subject before the scan;
- and
- displaying both the image and data indicative of the physiological state.
A system, comprising:
- a data packager that packages an image of a region of interest of a subject and data indicative of at least one of a physiological or a behavioral state of the subject together, wherein the image is generated with image data produced by an imaging system used to scan the subject and the state is obtained prior to scanning the subject.
A method, comprising:
- obtaining a signal indicative of a physiological or behavioral state of a subject before a scan of the subject;
- adapting or changing a planned scan protocol for the scan based on the signal;
- and
- scanning the subject based on the adapted or changed scan protocol.
A method, comprising:
- obtaining a signal indicative of a physiological or behavioral state of a subject before a scan of the subject;
- generating supplemental data indicative of an affect of the state on tracer uptake in the subject state based on the signal;
- and
- displaying the image with the supplemental data.
A method, comprising:
- obtaining a signal indicative of a physiological or behavioral state of a subject before a scan of the subject;
- generating a correction for an image or image data from the scan based on the signal, wherein the correction corrects for an anticipated affect of the state on tracer uptake in the subject state;
- and
- correcting the image or image data based on the correction.
A method, comprising:
- correcting, via a processor, a tracer uptake value for a target region of interest based on a tracer uptake correction factor.
A system, comprising:
- a processing component, including:
- a target ROI tracer uptake determiner that determines a tracer uptake value for a target region of interest;
- a non-target ROI tracer uptake determiner that determines a concurrent tracer uptake value for at least one non-target region of interest;
- and
- a process tracer uptake determiner that determines a concurrent tracer uptake value for at least one physiological process;
- and
- a target ROI tracer uptake corrector that corrects the tracer uptake value for the target region of interest based on at least one of the concurrent tracer uptake value for the at least one non-target region of interest or the concurrent tracer uptake value for the at least one physiological process.
