1. A method for breast cancer detection with an x-ray scanner, the method comprising: scanning a patient with the x-ray scanner, the scanning providing a frame of data representing breast tissue in the patient; classifying patches of the frame of data as of interest or not based on intensity; determining a probability of breast cancer for the patches that are of interest using a deep learnt regression at least partially trained on non-x-ray data; classifying the patches with the probability over a threshold using a machine-learnt classifier; and displaying an indication of breast cancer for the patient based on an output of the classifying using the machine-learnt classifier.
