IDENTIFICATION OF REGIONS OF INTEREST AND EXTRACTION OF TIME VALUE CURVES IN IMAGING PROCEDURES
First Claim
1. A method of extracting at least one time-value curve to determine a protocol in an imaging procedure using an imaging system, comprising:
- determining a first M-dimensional data set of pixel values of a portion of a body of the patient at a first time using the imaging system, wherein M is an integer;
determining at least a second M-dimensional data set of pixel values of the portion at a second time using the imaging system;
computing a predetermined number of correlated segments of the imaged portion corresponding to a predetermined number of regions of interest of the patient by computing a similarity metric of a time series of pixel values;
computing the at least one time-value curve for at least one of the regions of interest; and
determining a protocol for a diagnostic scan using the image system based at least in part upon data from the time value curve.

Abstract
A method of extracting at least one time-value curve to determine a protocol in an imaging procedure using an imaging system, includes: determining a first N-dimensional data set of pixel values of a portion of a body of the patient at a first time using the imaging system, wherein N is an integer; determining at least a second N-dimensional data set of pixel values of the portion at a second time using the imaging system; computing a predetermined number of correlated segments of the imaged portion corresponding to a predetermined number of regions of interest of the patient by computing a similarity metric of a time series of pixel values; computing the at least one time-value curve for at least one of the regions of interest; and determining a protocol for a diagnostic scan using the image system based at least in part upon data from the time value curve.

18. A system for extracting at least one time-value curve to determine a protocol in an imaging procedure, comprising:
-
an input system for input of data output from at least one imaging system, the data comprising a first M-dimensional data set of pixel values of a portion of a body of the patient at a first time, wherein M is an integer, and at least a second M-dimensional data set of pixel values of the portion at a second time; at least one processor in communicative connection with the input system and adapted to compute a predetermined number of correlated segments of the imaged portion corresponding to a predetermined number of regions of interest of the patient by computing a similarity metric of a time series of pixel values and computing the at least one time value curve for at least one of the regions of interest; and at least one parameter generator system to determine a protocol for a diagnostic scan using the image system based at least in part upon data from the time value curve. - View Dependent Claims (19, 20, 21, 22, 23)
