Radiologist Assistant Radiologist assistants (RAs) are radiologic technologists with additional education and responsibilities. The RAs responsibilities include conducting radiologic patient assessments, participating in patient management, and performing radiologic procedures. Similar to physician assistants, the RA works under the supervision of a physician, specifically a radiologist. RAs do not diagnose, order tests or procedures, or prescribe medications.
Dosimetrist (in radiology) The medical dosimetrist is a member of the radiation oncology team who has knowledge of the overall characteristics and clinical relevance of radiation oncology treatment machines and equipment, is cognizant of procedures commonly used in brachytherapy an
Diagnostic Medical Sonographer Diagnostic medical sonographers use sound waves (ultrasound) to create images that show the shape and composition of body tissues, organs, and pathologies. These images assist physicians in diagnosing disease, injury, or other physical conditions. The sonographer will first record patient history, position the patient for ultrasound testing, and explain the procedure in detail. Although many sonographers are trained to use ultrasound on all body parts, some may specialize in neurosonography (brain), vascular sonography (blood vessels), echocardiography (heart), abdominal sonography (abdominal cavity), obstetrics/gynecological sonography (female reproductive system), or ophthalmologic sonography (eye). As with other medical imaging personnel, diagnostic medical sonographers work under the direct supervision of a physician.
Nuclear Medicine Technologist Nuclear medicine technologists use radiopharmaceuticals under a physicians supervision to produce images for diagnosis and for the treatment of some diseases. Radiopharmaceuticals, introduced into the body via injection, inhalation, or ingestion, aid in the diagnostic imaging of such organs as the heart, lungs, bone, liver, kidneys, and brain. These radioactive tracers are useful because they are attracted by certain internal organs and emit easily detectable high energy rays. Using sensitive instrumentation such as position emission tomography (PET), the nuclear medicine technologist can obtain images of the structure and function of the specific organ in question. These technologists are also concerned with the safe storage and disposal of these radioactive materials. They prepare and administer the radioactive materials, operate nuclear instruments, position patients for diagnostic procedures, and prepare information received from the examinations for the radiologists interpretation. Technologists must monitor radiation levels at all times to ensure the safety of patients and themselves
Radiation Therapist Radiation therapists administer doses of radiation to treat patients, primarily cancer patients. By applying high energy photon and electron beams to specific body areas, radiation therapy attempts to halt the spread of disease or to offer relief from symptoms. Radiation therapists deliver the course of radiation, give support and information to the patient, and work closely with oncologists to decide treatment options and to monitor patient progress. Cancer patients and their families often develop a meaningful relationship with these health care providers over the course of treatment.
Radiologic Technologist The title of radiologic technologist covers a wide range of health care professionals who use radiation and magnetic fields for diagnostic imaging. For most sections of the medical imaging field, the health care provider must first complete a radiography program and successfully pass the national certification examination in radiography before seeking additional training and certification in other medical imaging areas. Radiographers produce radiographs or images of all parts of the human body for use in diagnosing and treating illnesses. They are responsible for patient assessment and preparation for radiologic procedures and for image production for analysis by a radiologist.
Some radiographers may specialize in fluoroscopic examinations (watching a patients internal organs on a monitor or screen), in pediatrics or in orthopedics. Radiographers who are CT technologists use computerized tomography to view patient anatomy and disease from a cross-sectional perspective. Magnetic resonance imaging (MRI) technologists are also radiographers, but they are skilled in using magnetic fields and radiofrequency waves instead of ionizing radiation, to create images. Vascular/interventional technologists began as radiographers and then specialized in the imaging and treatment of blood vessels, ducts, and other structures. All radiologic technologists work under the direct supervision of a physician.
