Minimizing patient movement during CT-guided lung biopsy is an important factor in the procedure. To minimize movement, a vacuum cushion was used to evaluate its effectiveness. The subjects of this study were 116 patients aged 40 years or older who had good coordination with postural fixation and breathing control. Posture measurements were performed in the supine position, prone position, oblique position, and lateral position according to each position of the lung lesion biopsy lesion. Measurement positions were measured in the anterior, posterior, right, and left positions based on the anatomical posture. In the prone position, the mean difference between the non-use and the use of the posterior was 1.7905, and t=2.913 (p<0.01), and the mean difference between the non-use/use was statistically significant. The difference between the unused and used averages of left was 2.4105, and the difference between the left averages was also significant with t=3.684 (p<0.01). The difference between the unused and used averages of the right was 2.3263, with t=3.791 (p<0.01). The mean difference between unused and used is statistically significant. As a result of statistical analysis, the biopsy of the lung lesion using a fixation device showed less movement in all postures. It is considered that it is meaningful in that it is possible to conduct a more accurate biopsy procedure and minimize the patient's posture movement by using a fixation device during the CT-guided biopsy of the lung lesion.
