Maintain Functionality with Prostate Treatment Some of the concerns of patients come with the primarily revolved around urinary function and bladder function, and rectal function and sexual potency. With radiation, you want to be as precise as possible. The more precision you have the more radiation you could get to the cancer and the less radiation you can actually get to the normal tissue, therefore you have a better chance of curing the disease and less of a chance at radiating and damaging normal tissue. The prostate gland moves during therapy. The prostate gland is actually always moving. If the rectum fills, the gland is actually pushed forward. If the bladder fills up, the gland is actually pushed inferiorly or downward. It's very important to know where that motion is because when we know we could better direct and better aim our radiation at the prostate gland and avoid the normal tissues that surround the prostate tissue. The Calypso System is a GPS system for the prostate gland. It allows us to target the radiation to the prostate gland in the most precise way. There are three beacons that are implanted permanently into the prostate gland and there are three beacons sent out a little signal that is picked up by our machine so that every second during treatment, our machine is able to know the exact position of the prostate gland. If we’re able to know the exact position of the prostate gland, we’re able to know exactly where to direct the radiation treatments. We used the Calypso System because we want it to be able to direct the radiation almost like a smart bomb or a patriot missile. We wanted to be able to direct the radiation specifically at the cancer. All study shows that if you're bale to get a high enough dose to the cancer, you have a better chance at eradicating the cancer, killing the cancer, curing the patient. At the same time, we also wanted to minimize the exposure of a normal tissue that’s in the immediate vicinity of the prostate gland or the cancer. So, if we’re able to know the exact position of the prostate gland every second throughout therapy, we can actually target our radiation better. The Calypso System is a guidance system for the radiation beams.
