Method for determining the half-value layer in computed tomography scans using a real-time dosimeter: Application to dual-source dual-energy acquisition

•A modified lead-covered case method can determines the half-value layers.•The method does not require X-ray tubes to be fixed during measurements.•The method can be applied to dual-source dual-energy computed tomography scans.•The peak method shows a more accurate half-value layer than the integrat...
