Title:
コンパートメント解析のための画像データ処理システム
Document Type and Number:
Japanese Patent JP4901725
Kind Code:
B2
Abstract:
The invention relates to a data processing system ( 1 ) for the evaluation of image data, particularly of PET-images (I), that represent the time varying concentration of a tracer substance like F-MISO in an object ( 20 ). The data processing system ( 1 ) comprises a library module ( 48 ) with analytical solutions (Cj(t)) for several compartment models. Preferably the library also contains the analytical gradients with respect to the parameters of interest. From the library an appropriate solution for each study can be chosen by a user. The use of analytical functions together with the information about the error (sigmaA(t)) of the input data (either via noise models 43 or via a simulation 44 ) allows to extract all parameters mandatory to fully understand the kinetics of complex models (more than one tissue compartment) on a per-voxel basis in a robust way in real-time.
