Method and apparatus for classification of pixels in medical imaging
First Claim
1. An apparatus for medical imaging comprising:
- means for exposing an object to radiation;
means for collecting the radiation after attenuation through the object;
means for processing recorded attenuations; and
means for displaying a result of the processing in the form of a representation on an image of the object wherein the means for processing the recorded attenuations forms means for automatic classification of zones of the object into pathological or non-pathological classes, the means for automatic classification taking account of at least one classification input into the apparatus in advance in association with data that can be collected by the apparatus, and using this prior classification as a reference in order to produce a classification of the same type if there is similarity between the collected data and the data associated with this reference classification.

Abstract
An apparatus and method for medical imaging, particularly for mammography, wherein a body organ, such as a breast, is exposed to X-rays and the X-rays are collected after attenuation through the object. The recorded attenuations are processed and displaying a result of this processing in the form of a representation of an image of the object. The processing of the recorded attenuations form includes automatic classification of zones of the breast into pathological or non-pathological classes. The automatic classification takes into account at least one classification input into the apparatus in advance in association with data that can be collected by the apparatus, and using this prior classification as a reference in order to produce a classification of the same type if there is similarity between the collected data and the data associated with this reference classification.
