A high energy guide is needed for the measurement of high energy (greater than 1 MV) x-ray focal spots. Discussion of current methods and calculations for x-ray focal spot sizes and how the measured x-ray focal spot relates to calculation for imaging system performance and effective spot size.
Focal Spot; High Energy; MeV
Recommended by the committee to develop standard measurement for high energy focal spots.
The title and scope are in draft form and are under development within this ASTM Committee.
