Embodiment Construction

[0038] The detailed description that follows details several embodiments of the invention. The details of these examples do not limit the invention. Rather, they describe examples of possible advantageous features that could be used in connection with the invention. The instructions detail the combination of anatomical and functional images. However, the invention can also be used for other image combinations. For example, two anatomical images may be used or two functional images may be used. When using two anatomical images, the first image may comprise an MR image and the second image may comprise a CT image, for example, or in another example, two CT images or two MR images are used. This allows converting a region of interest defined in the first anatomical image to a corresponding region of interest in the second anatomical image. The first image may also be a functional image with manually or automatically marked regions of interest. For example, the region of inte...

Abstract

The present invention provides a system for quantifying medical image data. The first image acquisition module (1) is used to acquire the first image (A). The second image acquisition module (2) is used to acquire the second image (B). The space transformation acquisition module (3) is used to acquire space transformation information representing the corresponding relationship between points in the first image and corresponding points in the second image. The identification module (4) is used to identify the first image area (C) in the first image (A). The transformation module (5) transforms the first image region (C) into a corresponding second image region (C') in the second image (B) based on the spatial transformation information. The quantization module (6) is adapted to calculate a quantization associated with the second image region (C') by accessing image values ​​of the second image (B) within the second image region (C').

Description

technical field [0001] The present invention relates to quantification of medical image data. Background technique [0002] In clinical and preclinical research, data from various modalities are used to aid research on drugs or treatments. Data from multiple modalities (such as CT, MR, PET or SPECT) yield different information and a combination of such information can be used to draw conclusions. For example, PET and SPECT data can yield functional information, while CT and MR can yield anatomical information. In order to fuse such information, the anatomical region to be studied (such as an organ or tumor region) can first be outlined in a CT or MR image. The functional capacity of the same area is then investigated via information from PET or SPECT images. To ensure that the same area is being studied in both modalities, an initial image-to-image registration can be performed on the data to ensure that the size, overlap and orientation of the two images are comparable. ...
