Abstract
The introduction of automatic tube current modulation (ATCM) has resulted in more complex relationships between Computed Tomography scanner parameters, patient body contours, radiation dose, and image quality. ATCM automatically modulates tube current angularly and/ or along the longitudinal axis, by adjusting x-ray flux based on attenuation characteristics and selected scanner protocols. This study aims ...
