Abstract:
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; and wherein the means for automatic classification makes a classification of pixels of an image of the object at the same location in a several dimensional space, the dimensions of this space each corresponding to the value of a grey level at a given instant of a contrast appearance rate at the pixel considered.
