Transrectal Near-Infrared Optical Tomography for Prostate Imaging
Abstract
The objective of this research is to explore the technology of trans-rectal near-infrared (NIR) optical tomography for accurate, selective prostate biopsy. The research in the first year has made several key advancements that may render future testing of the approach at in vivo settings. The development of a 20mm diameter axial-imaging cylindrical applicator for trans-rectal NIR optical tomography represents an unprecedented engineering approach in the development of internal-imaging NIR tomography applicator. Simulations and experiments both demonstrated the feasibility of imaging target with absorption contrast by use of trans-rectal NIR tomography applicator, even though the interrogation depth may be limited to ~15mm. The findings from a trans-rectal NIR probe having elliptical cross-section gives an option of potentially imaging deeper tissue volumes up to 20mm at axial-imaging geometry.
