Computed Tomography is one of the most popular diagnostic tools available to medical professionals. However, its diagnostic power comes at a cost to the patientsignificant radiation exposure. The amount of radiation exposure is a function of the number of angular measurements necessary to successfully reconstruct the imaged volume. Compressed sensing on the other hand is a technique that allows...

Low in cost and high in diagnostic value with applications that cover nearly every tissue in the human body, medical ultrasound has become one of the most popular imaging exams worldwide – and not just among healthcare professionals. Its lack of ionizing radiation amid gathering public concern about the cancer-causing potential of X-rays, particularly those in CT, makes ultrasound appealing to ...

These issues support the need for medical imaging and radiation therapy professionals to understand how the Medicare progr...

Use of computed tomography (CT) as a medical diagnostic imaging tool has increased in recent decades because of its technical advances in data acquisition speed and image reconstruction technology. The increased reliance on CT was accompanied by increased patient exposure to ionizing radiation, however, and concerns among radiologic professionals and the public regarding CT dose resulted in inc...
