1. A method of breast imaging for medical diagnosis of the presence of breast lesions comprising,passing a non-ionizing radiation through the breast in a range of frequencies which are differentially absorbed or transmitted by lesions within the breast,detecting the radiation which has passed through the breast,generating an electronic image of the breast,converting the image so generated into a digital format of pixel brightness values,electronically normalizing the digital image by compensating for the non-uniformity of the radiation field component of the image to enhance the contrast of areas representing locally high differential absorption or transmission of the radiation through the breast,and displaying the normalized image for analysis by a medical practitioner.
