Prostate contouring using CT alone is difficult. To overcome the uncertainty, CT/MRI registration using a fiducial marker is generally performed. However, visualization of the marker itself can be difficult with MRI.
Prostate cancer is the most common non-cutaneous cancer among men in the USA. Focal laser thermal ablation (FLA) has the potential to control small tumours while preserving urinary and erectile function by leaving the neurovascular bundles and urethral sphincters intact.
A methodology to study the relationship between clinical variables [e.g., prostate specific antigen (PSA) or Gleason score] and cancer spatial distribution is described.
