Slide 1: CAREER IMAGING TECHNOLOGY IN BY Bibin Chacko Slide 2: Introduction: To Medical Imaging Technology Diagnostic radiology technologists may specialize in a particular imaging area: RADIOGRAPHERS (X-Ray Technician) MAMMOGRAPHERS MAGNETIC RESONANCE TECHNOLOGISTS (M.R.I. Technician) COMPUTED TOMOGRAPHY TECHNOLOGISTS (C.T. Technician) CARDIOVASCULAR-INTERVENTIONAL TECHNOLOGISTS NUCLEAR MEDICINE TECHNOLOGISTS SONOGRAPHERS (Ultrasound) BONE DENSITOMETRISTS MEDICAL DOSIMETRISTS RADIATION THERAPISTS Slide 3: RADIOGRAPHERS They use radiation (x-rays) to produce black-and-white images of anatomy. The images are captured on film, computer or videotape. X-rays images may be used to detect bone fractures, find foreign objects in the body, and demonstrate the relationship between bone and soft tissue. The most common type of x-ray exam is chest radiography. MAMMOGRAPHERS They produce diagnostic images of breast tissue using special x-ray equipment. Under a federal law known as the Mammography Quality Standards Act, mammographers must meet stringent (strictly) educational and experience criteria in order to perform mammographic procedures. Slide 4: MAGNETIC RESONANCE TECHNOLOGISTS They are specially trained to operate MR equipment. During an MRI scan, atoms in the patient's body are exposed to a strong magnetic field. The technologist applies a radiofrequency pulse to the field, which knocks the atoms out of alignment. When the technologist turns the pulse off, the atoms return to their original position. In the process, they give off signals that are measured by a computer and processed to create detailed images of the patient's anatomy. COMPUTED TOMOGRAPHY TECHNOLOGISTS They use a rotating x-ray unit to obtain "slices" of anatomy at different levels within the body. A computer then stacks and assembles the individual slices, creating a diagnostic image. With CT technology, physicians can view the inside of organs - a feat not possible with general radiography. Slide 5: CARDIOVASCULAR-INTERVENTIONAL TECHNOLOGISTS They use sophisticated imaging techniques such as biplane fluoroscopy to help guide catheters, vena cava filters, stents or other tools through the body. Using these techniques, disease can be treated without open surgery. NUCLEAR MEDICINE TECHNOLOGISTS They administer trace amounts of radiopharmaceuticals to a patient to obtain functional information about organs, tissues and bone. The technologist then uses a special camera to detect gamma rays emitted by the radiopharmaceuticals and create an image of the body part under study. The information is recorded on a computer screen or on film. Slide 6: BONE DENSITOMETRISTS They use a special type of x-ray equipment to measure bone mineral density at a specific anatomical site (usually the wrist, heel, spine or hip) or to calculate total body bone mineral content. Results can be used by physicians to estimate the amount of bone loss due to osteoporosis, to track the rate of bone loss over a specific period of time, and to estimate the risk of fracture. MEDICAL DOSIMETRISTS They determine how much radiation will be delivered to a tumor site. Under the supervision of a medical physicist, they calculate and generate radiation dose distributions in accordance with the treatment plan developed by the radiation oncologist. Medical dosimetrists use their knowledge of physics, anatomy and radiobiology to design optimal treatments that apply an effective dose to the targeted area while sparing normal tissue that surrounds it. Slide 7: RADIATION THERAPISTS They administer targeted doses of radiation to the patient's body to treat cancer or other diseases. As the radiation strikes human tissue, it produces highly energized ions that gradually shrink and destroy the nucleus of malignant tumor cells. Radiation therapists are highly skilled medical specialists educated in physics, radiation safety, patient anatomy and patient care. They typically see each of their patients three to five days a week throughout a four- to seven-week treatment plan. SONOGRAPHERS They use sound waves to obtain images of organs and tissues in the body. During an ultrasound examination, the sonographer places a transducer in contact with the patient's body. It emits high-frequency sound waves that pass through the body, sending back "echoes" as they bounce off organs and tissues. Special computer equipment converts those echoes into visual data. Slide 8: Skills & Knowledge Developed in this Field of Study Skills developed - patient care and monitoring skills, the application of the theories in the selected clinical areas, safety practices, team work, interpersonal communications, adaptation, oral and written presentation of technical information, use of technical equipment and problem solving. Students develop specialities in one or more of the following areas: interventional imagery, computer tomography, magnetic resonance, ultrasound and cardiac catheritization. Slide 9: After graduation many individuals can get registered in the profession by taking and passing an entry-level certification examination. The four main certification bodies in the radiologic sciences are the American Registry of Radiologic Technologists (ARRT), the American Registry of Diagnostic Medical Sonographers (ARDMS), the Nuclear Medicine Technology Certification Board (NMTCB) and the Medical Dosimetrist Certification Board (MDCB). Slide 10: As technology advances and the American population ages, the demand for radiologic exams and procedures has soared (rised). The country needs a growing number of qualified professionals to provide medical imaging and radiation therapy. The U.S. Bureau of Labor Statistics predicts that the nation will need 75,000 more radiographers and 7,000 more radiation therapists in 2010 than it did in 2000. Wages of radiologic technologists are competitive with other health professionals who have similar educational backgrounds. A 2001 survey by the American Society of Radiologic Technologists showed that wages averaged about $16 per hour for entry-level radiographers and $20 per hour for entry-level radiation therapists. With experience, additional education or supervisory responsibilities, wages can reach an average of $20 to $25 per hour. In addition, many employers allow radiologic technologists to work flexible schedules, including part-time or evenings. Slide 11: Additional Resources For a list of accredited (officially recognized) educational programs in nuclear medicine, visit the Web site of the Joint Review Committee on Educational Programs in Nuclear Medicine Technology at For information about accredited educational programs in sonography, click on, the Web site of the Joint Review Committee on Education in Diagnostic Medical Sonography. For names and addresses of accredited schools in radiography and radiation therapy, contact the Joint Review Committee on Education in Radiologic Technology at For information about entry-level certification examinations in radiography, radiation therapy and nuclear medicine that are offered by the American Registry of Radiologic Technologists, go to Information about certification examinations offered by the Nuclear Medicine Technology Certification Board may be found at The Web site of the American Registry of Diagnostic Medical Sonographers has information about certification examinations in sonography. Go to Slide 12: Medical Radiation Technologists Board of Queensland's Overseas Trained Medical Imaging Technologists If your qualifications were not obtained in Australia or New Zealand, you will need to obtain a Statement of Accreditation from the Australian Institute of Radiography (AIR) before applying to the Board for registration in Queensland. Graduates with overseas qualifications who have completed a Degree Program accredited by the AIR and who fulfill specified criteria may apply directly for a Statement of Accreditation. For further information, please refer to the "Overseas" category of the AIR website: Slide 13: Employment Opportunities Job Outlook Positions in medical imaging are expected to grow faster than average through 2010. Salary Information Salary range for the middle 50% in 2001: $32,370 to $46,510. Potential Career Growth Career growth is dependent on the size of the employer and the need to obtain additional formal education in some cases. Slide 14: A career in medical imaging technology offers a promising future, job stability and good salaries in India as well as in abroad. "And Avoid Saturation" "So Keep your Passports ready". Slide 15: THANK YOU From MOHSIN ,TUSHAR ,VISHNU ,DEVARSHI & BIBIN
