Abstract

The purpose of the optimal environment of the MRI room to measured luminance and illuminance of the MRI room and the monitor. University Hospital (n = 6) of the MRI (n = 10) in the luminance and illuminance Light Probe Xi Unfors (Unfors Instruments AB, Billdal, Sweden) was measured by using the. Black luminance level and white level of illuminance is repeated three times in the middle of the side of the monitor to obtain the mean and standard deviation using a t-test statistical processing was of significance test. Monitor luminance and black level in the average $1.78cd/m^2$, the standard deviation was $0.85cd/m^2$, white level average of $43.58cd/m^2$, the standard deviation of $13.19cd/m^2$. Illuminance of MRI room was the lowest value measured in accordance with the 30.5 lux, the maximum value is 601.3 lux, mean was measured by a variety of 177.86 lux. Luminance and illuminance of the MRI room and monitor is found to have statistically significant difference (p < .05). In conclusion, refer to the recommended standard of MRI and room monitor luminance and illuminance and to create an optimal environment.

MRI 검사실의 최적환경을 목적으로 검사실 및 모니터의 휘도와 조도를 측정하였다. 대학병원(n = 6)의 MRI(n = 10)에서 휘도와 조도를 Unfors Xi Light Probe(Unfors Instruments AB, Billdal, Sweden)를 이용하여 측정하였다. 휘도는 black level과 white level을 조도는 모니터의 측면의 중앙에서 3회 반복하여 평균과 표준편차를 구하여 t-test를 이용하여 유의성 검정의 통계적 처리를 하였다. 모니터 휘도는 black level에서 평균 $1.78cd/m^2$, 표준편차 $0.85cd/m^2$이었고, white level에서는 평균 $43.58cd/m^2$, 표준편차 $13.19cd/m^2$로 측정되었다. MRI 검사실 조도는 최저값 30.5 lux, 최대값 601.3 lux, 평균 177.86 lux로 측정되었고, 휘도와 조도는 통계학적으로 유의한 차이가 있다(p < .05). MRI 모니터 및 검사실 휘도와 조도의 권고 기준을 참고하여 최적인 환경을 조성하도록 한다.
