Method and apparatus for detecting anatomical elements
First Claim
1. A method for detecting anatomical elements comprising:
- receiving a test image;
generating one or more feature vectors, wherein generating each feature vector comprises convolving a respective feature with the test image;
generating a classified image by using the one or more feature vectors to apply an image classifier to the test image, the image classifier comprising at least one decision tree, wherein application of the image classifier to the test image comprises feeding the one or more feature vectors through the at least one decision tree to generate at least one pixel value of the test image, the classified image comprising a plurality of pixel values, wherein generation of each pixel value assigns the pixel value a probability that its associated pixel is related to an anatomical element; and
evaluating, using a processor, the classified image using an anatomical model to detect at least one anatomical element within the classified image.

Abstract
A method, apparatus and computer program product are hereby provided to detect anatomical elements in a medical image. In this regard, the method, apparatus, and computer program product may receive a test image and generate a classified image by applying an image classifier to the test image. The image classifier may include at least one decision tree for evaluating at least one pixel value of the test image and the classified image may include a plurality of pixel values. Each pixel value may be associated with a probability that an anatomical element is located at the pixel location. The method, apparatus, and computer program product may also evaluate the classified image using an anatomical model to detect at least one anatomical element within the classified image.
