"Conjoint radiation oncology center" or "cancer center" means a multi-institution, multidisciplinary network to provide radiation therapy for cancer patients. Integration of patient care management, common utilization of personnel and equipment, and a single system of records between center institutions ensures optimal care regardless of entry portal.
"Dosimetrist" means a staff member who calculates, verifies, and develops treatment plans for the radiation dose distributions that will be delivered to patients. The dosimetrist is an essential member of the treatment planning team and works closely with radiation oncologists and radiation physicists.
"Megavoltage therapy" means the use of ionizing radiation in excess of one million electron volts. Energies above one million electron volts cause considerably less skin damage, increase depth dose markedly, and result in much less scatter from the therapeutic beam. Megavoltage machines are classified as follows:
Cobalt 60 units-emit gamma rays of approximately 1.2 million electron volts.
"Megavoltage therapy unit" means a piece of megavoltage therapeutic radiologic equipment that provides megavoltage therapy.
"New occurrence" means a course of treatment for a new occurrence on a given patient at a given radiation therapy facility. First-time radiation therapy at a new facility is based on each round of treatment.
"Radiation modality" means the method of applying ionizing radiation in the treatment of patients with malignant disease using megavoltage external beam equipment.
"Radiation oncologist" means a physician authorized user trained in accordance with 641-subrule 41.3(5).
"Radiation therapy facility" or "facility" means the physical space that houses a megavoltage therapy unit and accompanying support equipment.
"Radiation therapy physicist" means an individual who works closely with radiation oncologists and is responsible for the safe and accurate delivery of radiation to patients. A radiation therapy physicist conducts quality control programs for the equipment and procedures, as well as calibrating the equipment. A radiation therapy physicist shall practice in accordance with 641-subrule 41.3(6).
"Radiation therapy technologist" means an individual who possesses an Iowa permit to practice as a radiation therapist in accordance with rule 641-42.7 (136C).
"Service area" means the county in which the facility is located and any other counties from which the applicant expects to draw patients with a cancer diagnosis who need radiation therapy treatment.
"Simulation" means the precise mock-up of a patient treatment with an apparatus that uses planar X-rays, magnetic resonance imaging device, or computed tomography scanner, which is used in reproducing the two-dimensional or three-dimensional internal or external geometry to the patient, for use in treatment planning and delivery.
"Superficial X-ray therapy" means the use of a conventional X-ray machine, which generates X-rays of up to 150 kilovolts (150 kv), to treat superficial lesions, such as skin cancer.
"Treatment" means radiation fields applied in a single patient visit fraction or delivery session.
