They select and set up appropriate equipment for the test, explain the procedure to patients, help patient to assume the correct physical position, and put patients at ease. Sonographers observe the sound-wave display screen, adjust equipment to ensure a clear image, and maintain a log of ultrasonic tests. Training is one, two or four years in length. The one-year program is for those who have met qualification requirements in health care. They use medical instruments, radiographic images and other recordings of internal organs to examine and treat patients.
Surgeons also prescribe medications and dietary and activity programs.
New technology allows doctors to perform more tests and procedures, and in some cases, surgeons can now treat conditions that were previously seen as untreatable. The education is typically a four-year bachelor's degree, four years of medical school, three years of residency, and a subspecialty fellowship of two or more years. The job outlook is better than average growth. The job of a surgical technologist is to set up the operating room for surgery by preparing the patient, maintaining sterility, laying out the needed instruments, and assisting surgical staff into gowns, masks, and gloves. During surgery the surgical technologist passes instruments to the physician, keeps an accurate count of gauze, sponges and other supplies used, and may assist in various other ways, such as retracting tissues, cutting sutures and operating special equipment.
