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.
Claims20
A method, comprising:
- obtaining an image of a region of interest of a subject which contrasts a tracer uptake, 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 the physiological state impacts the tracer uptake before the scan;
- determining an expected value of the tracer uptake for the region of interest;
- determining a tracer uptake correction factor based on the physiological state before the scan;
- and
- correcting the expected value of the tracer uptake for the region of interest based on the tracer uptake correction factor;
- and
- concurrently displaying, via a display monitor, both the image and data indicative of the physiological state.

A system, comprising:
- a data packager, implemented by a configured hardware processor, that packages an image of a region of interest of a subject and data indicative of a physiological state and 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 physiological state and the behavioral state are obtained prior to scanning the subject;
- and
- a physiological state monitoring apparatus that includes at least one physiological monitor that determines the physiological state of the subject prior to the scan and the physiological state is used to correct an expected tracer uptake contrasted in the image.
A method, comprising:
- obtaining a signal indicative of a physiological state and a behavioral state of a subject before a scan of the subject;
- generating supplemental data indicative of an affect of the physiological state and the behavioral state on an expected tracer uptake in the subject state based on the signal;
- and
- displaying an image concurrently with the supplemental data.
