Linear Accelerator Radiation Machine

Intensity-Modulated Radiation therapy

This beast of a machine can be intimidating at first site. However, it is the latest in technology in treating prostate cancer as well as other forms of cancer. It is, of course, computer controlled with algorithms designed specifically to each patient. Here is a brief explanation of what a male patient might experience during treatment.

The prostate cancer patient enters the room and removes clothing surrounding the treatment area. The patient lies on a traveling table. Their feet are held in place with a custom fitted form made of foam. Their head rests on a cushion. The technicians carefully adjusts the torso, aligning the tattoos previously placed on the buttocks with the alignment markers. The patient is given a rubber ring which he holds over his chest during treatment. The assisting technicians then leave the room. A thick door closes behind them.

Before treatments begin, the accelerator scans the treatment area to determine if the patient has properly prepared his body. The bladder must be sufficiently full of water and the lower intestine sufficiently free from obstruction. Treatments are brief; approximately 10 minutes. During that time, the large unit behind the patient’s head rotates 360 degrees forward, then 360 degrees backward. This is repeated until each day’s session is complete. Treatment is painless.

This procedure is typically repeated daily according to a predetermined schedule; 28-38 days, though some schedules may vary.
