3. Computed Tomography (CT)
Computed Tomography (CT) is the marriage of computers and X-rays. In modern machines, a rotating gantry holds a specialized X-ray tube, which generates a highly contoured X-ray beam in opposition to a detector array surrounding the patient. The patient moves through the gantry. Gantries weigh around 6,000 kilograms and can achieve speeds of 300 milliseconds […]
2. Ultrasound
Ultrasound utilizes ultrasonic sound waves in the 2–10 MHz range generated by a handheld piezoelectric crystal, sonically coupled to the skin by gel. A computer controls the process, allowing complex modeling of the sound beam. Higher frequencies have better resolution but poorer depth penetration. Transducer selection is a compromise between the depth of the area […]

Craniocaudal magnification showing malignant breast calcifications. Case courtesy of Melbourne Uni Radiology Masters, Radiopaedia.org, rID: 43928 X-rays are produced by bombarding a dense target (the anode) with high-energy (5–110 Kv) electrons, which produces a beam that radiates outward from a small point source. The beam is shaped with lead shutters. This geometry can lead to […]

In these learning materials Introduction to Imaging Please review this material prior to class and fill out the compare/contrast matrix as best you can. There is more information than can be covered in two 50-minute sessions, so the large-group session will attempt to cover concepts that tend to be confusing. Bring your questions. Remember, this […]
