Radiologic technologist The most common form of work for a radiologic technologist is radiography.
Radiographers produce x-ray films or radiographs.
They position patients properly so that the necessary body parts can be imaged and they also must limit the patients' exposure to the radiation. X-rays are produced either on film, the more traditional method, or on a monitor using digital imaging. MRI technologists do not use radiation, but instead, a machine that uses magnets and radiowaves for imaging. Radiation therapists, another type of technologist, use radiation to help treat and monitor cancer patients. Sonographers use ultrasound equipment which forms images from the echo of sound waves passed into a particular part of the body.
