Radiation Oncology Centers of Ventura County


At the Radiation Oncology Centers of Ventura County (ROCVC), you will experience the outstanding, comprehensive program that uses multiple approaches to treat and eliminate cancer.

Radiation Oncology Treatments Available at ROCVC

ROCVC is made up of a team of specialists led by radiation oncologists Dr. Timothy O'Connor and Dr. Henry Montes. The radiation oncologists are nationally recognized leaders in the field of radiotherapy, and experts in stereotactic radiosurgery. ROCVC offers a full range of advanced radiation therapy options, including:

Intensity Modulated Radiation Therapy (IMRT) IMRT is a painless, non-surgical treatment that precisely targets cancer cells while minimizing side effects. IMRT differs from 3D-CRT by varying the intensity of the radiation within each of the radiation beams. 

Prostate Brachytherapy is the implanting of radioactive seeds (each about the size of a grain of rice) into cancerous tissue through hollow needles. They may be permanent or temporary. Because they are so small, they cause little discomfort and are simply left in place after their radioactive material is used up.

Breast High Dose Rate (HDR) Brachytherapy – Mammosite® and Contura® is a tissue-conserving treatment similar to permanent seed implantation, only it is the temporary loading of radioactive seeds into the breast cavity following surgical removal of a cancerous mass. Plastic tubes called catheters or a balloon are inserted into the affected area and filled with saline solution. A portion of the catheter remains outside the body, and is connected to a computer-controlled High Dose Rate (HDR) machine that delivers the “seeds” twice a day for five days. 

Image-Guided Radiation Therapy (IGRT) uses high-resolution, three-dimensional images to pinpoint tumor sites, adjust patient positioning for maximum accuracy and deliver radiation therapy. These capabilities take IMRT and stereotactic IMRT technologies one step further with advanced imaging for greater precision and efficiency.
