The feasibility of a piecewise-linear dynamic bowtie filter
Purpose: The prepatient attenuator (or “bowtie filter”) in CT is used to modulate the flux as a function of fan angle of the x-ray beam incident on the patient. Traditional, static bowtie filters are tailored only for very generic scans and for the average patient. The authors propose a design for a...
