Inclusion Criteria

• •1. Subjects must be male (assigned male at birth) and 18 years or older.
• •2. Subjects must demonstrate the ability to understand and provide written informed consent.
• •3. Subjects must have histologically confirmed prostate cancer ( PCa) Note: Recruitment will be limited to a maximum of 50% of subjects with favorable intermediate-risk prostate cancer (PCa) Note: The histopathologic diagnosis must be obtained via "Prostate Biopsy (PB)", which for the purposes of the present study, is defined as both a systematic 12-core sextant random prostate biopsy and a targeted prostate biopsy. The targeted prostate biopsy can be performed via in-bore multiparemetric (mp) magnetic resonance imaging (MRI) prostate biopsy, cognitive mpMRI/ultrasound fusion prostate biopsy or software mpMRI/ultrasound fusion prostate biopsy. This "PB" must not be obtained greater than 1 year from the date of consent.
• •4. Subjects must have chosen to get focal therapy (partial gland ablation) for the treatment of prostate cancer and must be scheduled for partial gland ablation/focal therapy with any energy modality within 6 months following informed consent.
• •5. Subjects must have confirmed non-metastatic PCa following SOC screening for patients with unfavorable intermediate-risk and high risk PCa, a combination of computed tomography imaging of the abdomen and pelvis (CTAP) and technetium-99-mDP nuclear medicine bone scan (BS) and/or PSMA-PET imaging prior to enrollment. The imaging studies should be obtained within 6-months of enrollment.
• •6. Subjects must be designated as Eastern Cooperative Oncology Group (ECOG) performance status ≤ 2 or Karnofsky Performance Status Scale Score ≥ 60%, (see Appendix A).
• •7. Subjects must be fit to undergo general anesthesia and the FT surgical procedure, which includes adequate visualization of the prostate gland on transrectal ultrasound imaging, access to the urethra, perineum and rectum, as well as be tolerant of lithotomy positioning in the opinion of the treating investigator or the operating surgeon(s) if not the same as the treating investigator.
