Fine-Tuning Breast Cancer Screening Employing DOT

Scientists from Clemson University in association with scientists from the University of Bremen, Germany are working in unison to allay the physical discomforting sensation undergone during mammograms a matter of the past, and allowing for investigative imaging to be ultimately carried out in a house setting.

The group of scientists are aiming at refining DOT or Diffuse Optical Tomography for creating enhanced resolution imagery from a diffusion of infrared and detectable light for the early diagnosis of breast cancer. The procedure is cost-effective, has a higher safety quotient and less levels of discomfort associated with it in comparison to the X-rays that have been employed during mammograms. The issue with X-rays is producing an effective resolution for detecting smaller breast cancers.

The scientists are evolving mathematical forms for enhancing resolution.

The hitch with DOT is that it is a three dimensional procedure wherein photon density waves are initiated from a source that travels in a path resembling a banana because of multiple scattering, while in X-rays the path followed is straight that lends the mathematical form greater manageability and sharper resolution.

The scientists explicated that in DOT, the process becomes more safe for the body due to the near-infrared or near-viewable photons as compared to the radiation emitted by X-rays, however they are trickier to track due to the scattering and absorption. To tackle this problems, the scientists are evolving equations that would be aid to capture cancers that are 4 mms in extent to as tiny as 1mm.

Scientists vouch by the benefits of DOT that comprise of eradication of detrimental radiation to the body alongside eliminating the occurrences of false positives and negatives that arise due to mammography X-rays. With no damaging side effects of DOT, certain DOT version could eventually be given in a DIY (Do it yourself) scenario at one’s residence in the subsequent ten years. Along with breast screening, DOT could finally be employed as component of other diagnostic methods like ultrasound.

Researchers envisage that even in case DOT does not substitute mammography, the outcome of this research would be pertinent to all spheres of biomedical imaging and imminently be devices based on these procedures which all could make use from the comforts of one’s home.
