1. A computer program product embodied in a computer-readable medium for analyzing a first medical image to detect anatomical abnormalities therein, the first medical image acquired from a first type of imaging system having a first response characteristic, comprising:
- computer-aided detection (CAD) code comprising at least one neural network-based automated anatomical abnormality detection algorithm trained using training images acquired from a second type of imaging system having a second response characteristic different than the first response characteristic; and
transforming code based on said first and second response characteristics for transforming pixel values of the first medical image to approximate values that would have been obtained if the first medical image had been acquired using the second type of imaging system such that said CAD code is applicable for the first medical image.

19. A method for analyzing medical images to detect anatomical abnormalities therein, comprising:
-
receiving a medical image; applying a computer-aided detection (CAD) algorithm to said medical image to detect anatomical abnormalities therein, wherein the CAD algorithm is a neural network-based automated anatomical abnormality detection algorithm; and prior to said applying said CAD algorithm, performing the steps of; identifying a first response characteristic associated with an acquisition of the medical image; determining whether the first response characteristic is substantially similar to a second response characteristic associated with an acquisition of a plurality of training images used to train the CAD algorithm; and if said first response characteristic is not substantially similar to said second response characteristic, transforming pixel values of said medical image to approximate pixel values that would have been obtained if the medical image had been acquired in a manner associated with said second response characteristic, such that said CAD code is applicable for the medical image. - View Dependent Claims (20, 21, 22, 23)
