Interstitial Assessment of Architectural Heterogeneity in Prostate Cancer Using a Fine Needle Photoacoustic Probe

Interstitial Assessment of Architectural Heterogeneity in Prostate Cancer Using a Fine Needle Photoacoustic Probe

In this project, we will integrate the Photoacoustic (PA) technology into a prostate biopsy procedure through a fine needle probe. The needle probe will be in the shape of a biopsy needle and compatible with the needle insertion mechanism in the transrectal ultrasound (TRUS) probe. When inserted into the prostate, the fine needle PA probe will assess the histological information in its surrounding tissue without any tissue extraction. The needle probe has been tested in prostate tissue samples and whole human prostates ex vivo.
