Prostate cancer radiotherapy surgery. Surgeon inserting radioactive sources into a patient's prostate gland. The radioactive sources are being implanted using needles inserted through a template (black square), through the perineal skin, and then guided to the prostate gland using a trans-rectal ultrasound probe. This implantation of radioactive sources is a procedure known as brachytherapy, a form of radiotherapy. The radiation from the radioactive sources kills the cancerous cells. The syringe (lower right) is used to inflate the silicon sheath around the probe with water. This improves the quality of the ultrasound picture.
