High-z metal
WebDec 11, 2013 · High-Z materials caused under-dosage of 20%–25% in the region surrounding the metal and over dosage of 10%–15% downstream of the hardware. Gamma index test yielded Pγ <1 >99% for all low-Z cases; while for high-Z cases it returned 91% < Pγ <1 < 99%. Analysis of the depth dose curve of a single beam for low-Z cases revealed that, although ... WebFor the penetration of high-Z materials, relatively high power is required. This lead to the development of X-ray tubes for laboratory and field use of voltages up to 450 kV and cp power up to 4,5 kW. Because of design, performance and reliability reasons, most of these maximum power stationary anode tubes are today made in metal-ceramic ...
