The top of the cassette should be. When a film is critiqued, if the bony detail is too light so as to appear nonexistent, a 15% increase in kVp provides the necessary penetration. Each radiograph must include an appropriate marker that clearly identifies the patient’s right (R) or left (L) side. Additional views are added to better demonstrate an area in question or to assess motion or stability. The x-ray tube is horizontally directed with the CR entering the right side of the body. To conserve x-ray film and facilitate viewing, sometimes the film is divided so that multiple views of a body part are seen on a single film (Fig. This view demonstrates atlas rotation. Positioning photos, radiographic images, and radiographic overlays, presented side-by-side with the explanation of each procedure, show you how to visualize anatomy and produce the most accurate images. Paraspinal lines (pleural interface) can also be seen. Place the patient in an anterior oblique position. In smaller patients, the lower spectrum of the kV range is used; in larger patients, the upper range of kV is used. Central ray is angled 25 degrees caudally and enters midthyroid cartilage ≈3″ below the external auditory meatus, exiting at the C7 spinous process. Using the calipers, place the base bar under the chin. If there is a possibility of pregnancy, the examination should be delayed, if possible, until it can be determined the patient is not pregnant, either by a negative human chorionic gonadotropin test result or the start of menses. ID can be either up or down because of collimation. It includes a quick reference to appropriate positioning procedures, radiation protection standards, and space for recording technical exposure factors, and a practical technique system guide. The posterior cervical oblique positions (RPO and LPO) demonstrate the opposite side intervertebral foramen (e.g., RPO shows left foramen), and the anterior cervical oblique positions (RAO and LAO) demonstrate the same side intervertebral foramen (e.g., RAO shows right foramen). If C7 is poorly visualized, a swimmer’s view may be used. Filtration is used to cover the eyes.
