Optical approaches to breast cancer (BC) detection show |
|
promise over conventional methods because they have |
|
potential to work in the denser tissue of younger |
|
patients and because they do not use ionizing radiation |
|
which has been shown to induce cancer in some patients. |
|
Three technologies will be combined in this effort. (a) |
|
Optical probing, using controlled light at specific |
|
wavelengths, is becoming a respected approach to cancer |
|
tumor detection. A much-published RADAR-based method |
|
known as frequency-domain photon migration (FDPM) gives |
|
very high sensitivity. (b) Spectral fingerprint analysis |
|
of fluorescence emission is the basis for cancer and |
|
precancer classification affecting surface cells. This |
|
has been shown for cervical and lung cancers. (c) Reading |
|
images, such as x-ray films, allows the tumor to stand |
|
out relative to the expected complex image of the breast. |
|
An optical hardware system was envisioned and preliminary |
|
testing performed. Hardware was to be based on using |
|
technically similar systems used in unrelated industrial |
|
applications to make hardware development affordable. |
|
Specific systems were identified. Ultimately, |
|
collaborators could not be found to modify their systems, |
|
and system development proved to be prohibitively costly. |
|
Discussions with other researchers has provided a voice |
|
for this approach within the community, paving the way |
|
for valuable contributions to BC detection. |
