Ultrasound-guided placement of radiation therapy
Radiation therapy uses high doses of radiation to destroy cancer cells. Ultrasound is used to guide the placement of radioactive beads or needles (brachytherapy) directly into the cancerous tissue.
The radioactive beads are left in place and gradually decay, releasing radiation at the site of the tumor over a few days or weeks.

Ultrasound uses reflected sound waves to produce an image of organs and other structures in the body. For this procedure, gel or oil is applied to the skin to help transmit the sound waves.
