Summary

A shorter 150mm phantom can accurately measure dose for kV-CBCT, even with wide X-ray beams. A novel correction factor accounts for missing scatter radiation, making this method applicable in any radiation therapy facility.

Mass Analyzers: Common Types

The quadrupole mass analyzer consists of four cylindrical metal rods arranged in a diamond carrying a DC voltage and a radio-frequency AC voltage. The motion of ions through the quadrupole depends on the field strength, causing only ions of a certain m/z to resonate successfully and strike the detector at a given field strength. Though the transmission rate for these analyzers is high, the exact elemental composition of the sample is not determined because of low resolution; however, they are...
