Infrared Sensing of Normal and Malignant<br />
Tissues in Humanoid Phantoms<br />
Thomas Stubblefield<br />
My research project involves combining<br />
infrared sensors and antennas to detect tumors<br />
in human breast tissue. The idea is to<br />
try and create a prototype device that could<br />
potentially detect these tumors at an early<br />
stage. The device that is created will send<br />
microwaves through the breast tissue in order<br />
to excite the tissue. This will cause a<br />
temperature change in the corresponding<br />
tissue. Regular breast tissue will give different<br />
temperature readings compared to tumors.<br />
These temperatures will be captured<br />
by the infrared sensors and would then be<br />
used to create an image for the breast. The<br />
sensors have been procured and the microwave<br />
antenna is under fabrication. Ideally,<br />
the image created would be the temperature<br />
profile of the breast.<br />
Due to the presence of cancerous tumor,<br />
temperature asymmetry is induced between<br />
two breasts. This asymmetry is captured by<br />
the infrared sensors to indicate abnormality.<br />
This concept is used in breast thermography<br />
(BT). However, The Food and Drug Administration<br />
clearly states that BT is not a valid<br />
replacement for mammography when trying<br />
to diagnose breast cancer. In the proposed<br />
method, the temperature asymmetry would<br />
be amplified by the microwave signal for<br />
better sensitivity.<br />
