Home > Services > Medical Imaging Services > Diagnostic Imaging (X-Ray) Services Diagnostic Imaging (X-Ray) An x-ray machine generates and uses a small amount of ionizing radiation to produce an image of a selected body part. Radiation passes through the body part and the image is captured on a specialized imaging detector. What preparation is needed? Most x-ray exams require no special preparation. Who administers the examination? The x-ray exam is performed by a registered radiology technologist. What to expect Upon arrival to the hospital, if NOT pre-registered, please register in the Patient Registration Department, First Floor. Once registered, a registrar will direct you to Imaging Services. Check in at the sliding glass window. There is a potential risk that x-rays may cause an abnormality to an unborn child. All female patients within menstruating age will be asked if there is any chance of pregnancy BEFORE having an x-ray. In the event of pregnancy or possible pregnancy, the technologist will consult with your ordering physician or a radiologist. Depending on the part of the body that is being imaged, you may be asked to change into a gown. A registered technologist will position your body to obtain the necessary views. You will be asked to remain still or hold your breath while the technologist takes the image. Multiple images may be necessary. The technologist will then perform a quality review of captured images. Once a quality review has been completed, you will be instructed to change back into your clothes and the technologist will assist you in leaving. What about results? The images are studied and interpreted by a licensed radiologist. If you have any questions, please call the Imaging Services Department at 217-245-9541, ext. 3371.
