It does not require breast compression, is portable, and doesn't need specialized infrastructure.
It does not require a specialized technician, is autonomous, and economical compared to others dispositives.
Metabolic information, continuous monitoring, high specificity.
How does it work??
The proposed device consists of a stretcher with a transparent window below which the measuring system is placed. In this way, the patient lies face down on the stretcher with the breasts resting on the aforementioned window. This configuration prevents the compression of the breast between two plates, typical of traditional mammography systems.
The measurement system consists essentially of two or more lasers of different wavelengths within the NIR zone, a high sensitivity CCD camera and a galvanometric scanner that allows to direct the laser beam in order to scan the area to be studied. For each position of the laser, an image of the whole field is taken with the camera. In addition, a system of interferometric filters allows the selection of determined wavelengths, useful for the determination of the optical characteristics of the tissue.
