Assessment of longitudinal beam property and contrast uniformity for 256‐ and 320‐row area detector computed tomography scanners in the 160‐mm nonhelical volume‐acquisition mode

BACKGROUND: Because the x‐ray property of patient longitudinal axis in area detector computed tomography (ADCT) depends on a heel effect, radiation dose and beam quality are not uniform along the long axis of the patient. OBJECTIVE: This study aimed to measure the longitudinal beam properties and co...
