An x-ray technologist operates x-ray machines in hospitals, doctor’s offices, and other medical facilities. In addition to traditional x-rays, you may also work with other medical devices, such as MRI, CT, or ultrasound machines. In this role, you review the doctor's orders for imaging, explain how the patient must stand or lay for you to take x-rays, then take extra precautions when necessary to protect the patient from unnecessary exposure to radiation, such as placing an iron-lined apron over the patient's torso or waist. Some x-ray technologists have skills in taking images of a specific body part, while others take general x-rays.
