Quantification of medical image data

摘要

A system is provided for quantification of medical image data. First image obtaining means (1) are for obtaining a first image (A). Second image obtaining means (2) are for obtaining a second image (B). Spatial transformation obtaining means (3) are for obtaining spatial transformation information representing a correspondence between points in the first image and corresponding points in the second image. Identifying means (4) are for identifying a first image region (C) in the first image (A). Transforming means (5) are for transforming the first image region (C) into a corresponding second image region C′) in the second image (B) based on the spatial transformation information. Quantification means (6) are for computing a quantification relating to the second image region (C′) by accessing image values of the second image (B) within the second image region (C′).

1. A method of quantification of image data, comprising:
obtaining spatial transform information representing a correspondence between points in a first non-transformed image and corresponding points in a second non-transformed image; storing the spatial transform information in a computer memory; identifying a first image region in the first non-transformed image; with one or more processors, transforming the identified first image region to identify a corresponding second image region in the second non-transformed image based on the spatial transform information; and with the one or more processors, computing a quantification value relating to the second image region based on image values of the second non-transformed image within the second image region and image values of the first non-transformed image accessed from the first non-transformed image in accordance with the stored spatial transform.
