System and method of measuring disease severity of a patient before, during and after treatment
First Claim
1. A method of measuring extent and severity of disease in a patient, comprising the steps of:
- (a) acquiring a first anatomical image data set and a first functional image data set of the patient, said first anatomical image data set and said first functional image data set form a first co-registered composite image data set;
(b) identifying at least a volume of interest (VOI) within said first co-registered composite image data set;
(c) qualitatively and quantitatively analyzing said first co-registered composite image data set including said VOI to determine extent and severity of the disease;
(d) acquiring a second anatomical image data set and a second functional image data set of the patient, said second anatomical image data set and said second functional image data set form a second co-registered composite image data set;
(e) performing a global, rigid registration of said first anatomical image data set and said second anatomical image data set, such that said first functional image data set and said second functional image data set are also globally registered;
(f) identifying at least a VOI within the globally registered image data set using the identified VOI within said first co-registered composite image data set;
(g) performing a local, non-rigid registration of said VOI within said first co-registered composite image data set and said VOI within the globally registered image data set, thereby producing a first co-registered serial image data set, said local, non-rigid registration being more precise than said global, rigid registration; and
(h) qualitatively and quantitatively analyzing said first co-registered serial image data set including the VOIs to determine severity of the disease and/or response to treatment of the patient.

Abstract
A system and method of obtaining serial biochemical, anatomical or physiological in vivo measurements of disease from one or more medical images of a patient before, during and after treatment, and measuring extent and severity of the disease is provided. First anatomical and functional image data sets are acquired, and form a first co-registered composite image data set. At least a volume of interest (ROI) within the first co-registered composite image data set is identified. The first co-registered composite image data set including the ROI is qualitatively and quantitatively analyzed to determine extent and severity of the disease. Second anatomical and functional image data sets are acquired, and form a second co-registered composite image data set. A global, rigid registration is performed on the first and second anatomical image data sets, such that the first and second functional image data sets are also globally registered. At least a ROI within the globally registered image data set using the identified ROI within the first co-registered composite image data set is identified. A local, non-rigid registration is performed on the ROI within the first co-registered composite image data set and the ROI within the globally registered image data set, thereby producing a first co-registered serial image data set. The first co-registered serial image data set including the ROIs is qualitatively and quantitatively analyzed to determine severity of the disease and/or response to treatment of the patient.

14. A system for measuring extent and severity of disease in a patient, comprising:
-
imaging device for acquiring a plurality of anatomical image data sets and a plurality of functional image data sets of the patient, said plurality of anatomical image data sets and said plurality of functional image data sets form a plurality of co-registered composite image data sets;
a user device for identifying at least a volume of interest (VOI) within a co-registered composite image data set of said plurality of co-registered composite image data sets, and identifying at least a VOI within a globally registered image data set of a plurality of globally registered image data sets using the identified VOI within said co-registered composite image data set; and
a computer system for performing the following steps;
qualitatively and quantitatively analyzing a first co-registered composite image data set of said plurality of co-registered composite image data sets including the identified VOI to determine extent and severity of the disease;
performing a global, rigid registration of a first anatomical image data set and a second anatomical image data set of said plurality of anatomical image data sets, such that a first functional image data set and a second functional image data set of said plurality of functional image data sets are also globally registered;
performing a local, non-rigid registration of the VOI within said first co-registered composite image data set and the VOI within the globally registered image data set, thereby producing a first co-registered serial image data set, said local, non-rigid registration being more precise than said global, rigid registration; and
qualitatively and quantitatively analyzing said first co-registered serial image data set including the VOIs to determine severity of the disease and/or response to treatment of the patient. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41)
