Three-Dimensional Conformal Radiation Therapy is a treatment technique that utilizes CT images to create an individualized treatment for each patient. The CT images allow our physicians to define the tumor volume and treatment area in three-dimensions. The physicians then work directly with our certified medical dosimetrist to create the treatment plan. External beam radiation fields are implemented using the CT data to conform to the shape of the tumor in three dimensions (length, width, and height). This process of planning provides high radiation dose to cancerous areas within the body while minimizing the amount of radiation administered to healthy tissue. Typical 3D conformal treatment plans consist of multiple external beam fields, each having a varying degree of rotation around the patient. For this type of cancer therapy, the patient will undergo treatment 5 days a week for about 6 weeks.
