IDENTIFICATION OF REGIONS OF INTEREST AND EXTRACTION OF TIME VALUE CURVES IN IMAGING PROCEDURES

摘要

A system and method of extracting at least one time-value curve enables determination of a protocol for a patient in an imaging procedure. The method includes the step of determining a series of 0 through T M-dimensional data sets of pixel values of an imaged portion of the patient acquired using an imaging system. M and T are integers, and the 0 and T data sets correspond to sets at times t=0 and t=T, respectively. Other steps include: computing a predetermined number of correlated segments of the imaged portion corresponding to a number of regions of interest 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 those regions; and determining a protocol for a diagnostic scan using the imaging system based at least in part upon data from the at least one time value curve.
