Experimental validation of a method characterizing bow tie filters in CT scanners using a real-time dose probe
Purpose: Beam-shaping or “bow tie” (BT) filters are used to spatially modulate the x-ray beam in a CT scanner, but the conventional method of step-and-shoot measurement to characterize a beam’s profile is tedious and time-consuming. The theory for characterization of bow tie relative attenuation (CO...
