Abstract
|
|
|
We investigated the characteristic of invasive method and non-invasive method when we were measuring the X-ray tube voltage and X-ray tube current, exposure time.
We concluded that ;
1. For CV(coefficient of variation) of KVp instrument, Dynalyzer3 showed high degree of trust in 0.001~0.004.
2. For CV(coefficient of variation) of mA and sec instruments, the invasive method showed high degree of trust.
3. Considering the perchance price and problem of measurement, we concluded that the KVp test cassette and Digital mAs-meter, Spinning top were suitable instrument for KVp, mA, sec.
