Fluorescence-Guided Robotic Surgery

Description

Recent breakthrough developments in the field of targeted radiotracers are now enabling the detection of prostatic tissue in lymph nodes using PET-CT or PET-MRI imaging. These radiotracers target the prostate-specific membrane antigen (PSMA), a membrane-bound receptor which is highly upregulated in all stages of prostate cancer. To date, however, it is still challenging to remove these lesions as diagnostic knowledge cannot be used for a precise therapy in a straight forward manner. Instead, diagnostic images must be mentally fused with the partially visible anatomy. This approach is associated with a high level of uncertainty and requires a lot of experience, especially in the presence of organ deformation. The aim of this multidisciplinary research project is to investigate the feasibility of computer-assisted fluorescence-guided surgery using prostate-specific membrane antigen (PSMA)-targeted imaging probes. The main scientific contributions so far are related to intra-operative data fusion using fluorescent structures [4-7] as well as the development of a fluorescent PSMA-based dye [2,3].
