Abstract: What is disclosed is a software interface tool for breast cancer screening that is designed for medical professionals to view and analyze suspicious regions for hot spots and hence facilitate a determination of whether identified areas of breast tissue are cancerous. Isotherm maps are constructed at designated temperature resolution. Maps are displayed on the screen. Point & click on the isotherm map can extract temperature values of pixels within the region covered by the isotherm contours. Also provided are isothermic views at different viewing angles which is advantageous for visual detection. Additional functionalities for hotspot selection, cropping, zooming, viewing at different angles, etc. are also enabled by the present software interface. The present software interface further utilizes a tumor detection method which is also disclosed herein.

Abstract: What is disclosed is a system and method for detecting cancerous tissue in breast tissue using a thermal image. In one embodiment, the present tumor detection method involves selecting a region of interest in the thermal image to be processed for breast cancer screening. Thereafter, a percentage of pixels p1 in the selected region having a temperature Tpixel1, where T1≦Tpixel1≦T2, is determined. A percentage of pixels p2 in the selected region having a temperature Tpixel2, where T3T≦Tpixel2, is determined. A ratio p3=Pedge/Pblock is also determined, where Pedge is a number of pixels around a border of a suspected tumor within the selected region, and Pblock is a number of pixels in a perimeter of the selected region. A decision fusion rule R, as more fully disclosed herein, is utilized to determine, based on these determination whether tissue within that region is cancerous, or non-cancerous, or is suspicious of being cancerous.

Abstract: What is disclosed is a system and method for the detection of cancerous tissue by analyzing blocks of pixels in a thermal image of a region of exposed skin tissue. In one embodiment, matrices are received which have been derived from vectors of temperature values associated with pixels in blocks of pixels which have been isolated from a plurality of thermal images of both cancerous and non-cancerous tissue. The vectors are rearranged to form matrices. A thermal image of a subject is received. Blocks of pixels which reside within a region of exposed skin tissue are identified and isolated. For each identified pixel block, an image vector comprising temperature values associated with these pixels is formed. The vector is provided to a classifier which uses the matrices to classify tissue associated with this block of pixels as being either cancerous or non-cancerous tissue.
