Abstract

This study performed and evaluated the performance test in 40 general X-ray units among diagnostic X-ray units, which were being used in hospitals of gyeongsangnam-do gimhae-si through X-ray tube variable limiting device ability test, the light field and X-ray field alignment test and collimation and beam alignment test of diagnostic X-ray unit. The results are as followings: In a variable beam limiting device ability test, the result of maximum X-ray field test showed that 4(10%) of were incongruent while the result of minimum X-ray field test represented that 5(12.5%) of were incongruent. The result of the light field and X-ray field alignment test showed 23(57.5%) of were within 2% of maximum permissible level and the other 17(42.5%) units were misalignment. The result of beam alignment test represented that 11(27.5%) coincided and another 11(27.5%) within $0.5^{\circ}$ respectively, 10(25%) were $0.6^{\circ}-1.5^{\circ}$ intervals, 7(17.5%) were $1.6^{\circ}-3^{\circ}$ and 1(2.5%) were more than $3^{\circ}$.
