영문 초록

This study uses the 'S-align' function to present a reference value of the X-ray tube angle for the realization of an image similar to that of the chest PA image during chest AP radiography. This study targeted dummy phantom and used a 17"×17" DR image receptor. The irradiation conditions were 110 ㎸p, 160 ㎃, 50 ㎳, and the distance between the central X-ray and the image receptor was set to 180 ㎝ and 110 ㎝, respectively. The end of the catheter was placed at the 11th thoracic height to indicate the nasogastric tube. In the case of lung apex length measurement, the mean value of measurement was 30.53±0.47 in PA. T 0°, TCA 5∼25°, TCE 5∼15° were 21.07±0.29, 27.60±0.21, 34.13±0.44, 39.86±0.31, 45.96±0.61 ㎜, 54.13±0.37 ㎜, 16.16±0.46 ㎜, 9.81±0.35 ㎜, 2.75±0.30 ㎜, respectively. For the depth of the catheter end, the average value measured at PA was 6.70±0.31 ㎜. T 0°, TCA 5∼25°, TCE 5∼15° were 15.72±0.38 ㎜, 24.10±0.50 ㎜, 29.24±0.86 ㎜, 34.35±0.35 ㎜, 41.06±1.08 ㎜, 48.07±0.38 ㎜, 12.85±0.25 ㎜, 7.92±0.36 ㎜, 3.01±0.39 ㎜, respectively. The length of the lung apex was similar to that of chest PA when the angle of incidence was adjusted from 5° to 10° in the leg direction, and the depth of the catheter tip was most similar when the X-ray tube angle was incident at 10° in the head direction. Therefore, To change the X-ray tube angle according to the purpose of the examination during the chest AP radiography using ‘S-align’ function is considered necessary.
