The purpose of this study is to investigate the correlation of blooming artifacts according to dilution ratio of contrast agent on CT angiography images. A total of 10 sets were prepared by differently setting the ratio of contrast media and saline in a ball phantom made by a 3D printer. CT scan images were obtained and reconstructed by MIP and MPR techniques to obtain axial, sagittal and coronal images, respectively. After, the diameter of the ball phantom of the image obtained after the test was measured each 30 times, a total 1800 times. As a result, the dilution of 20:80 in the coronal plane was the smallest (p<0.05). Similarly, when dilute to 20:80 in the sagittal plane of MIP, it was the smallest as 20.39 ± 0.08 mm (p<0.05). Correlation analysis between dilution ratio and measurement size confirmed strong negative correlations in all reconstructed images (p<0.05). In conclusion, the higher the dilution ratio of the contrast agent, the more difficult it is to measure actual blood vessel measurement. Therefore, this study may provide basic data in future studies on actual measurement. 본 연구에서는 CT 혈관조영 영상에서 조영제 희석비율에 따른 Blooming 인공물 발생의 상관성에 대하여 알아보고자 한다. 3D 프린터를 이용하여 PLA(Poly Lactic Acid)재질의 구형 팬텀을 자체 제작하였고 구형 팬텀 내부에 조영제와 식염수의 비율을 100:0부터 10:90으로 희석하여 총 10세트를 준비하였다. 이후 CT 횡단면 영상을 얻고 raw 데이터를 최대강도투사법, 다중평면 재구성 기법으로 재구성하여 각각 횡단면, 시상면, 관상면의 영상을 얻었다. 검사 후 얻은 영상의 구형 팬텀의 직경을 각각 30회씩 총 1800회 측정하였다. 측정결과, 다중 평면 재구성 기법 중 관상면에서 20:80으로 희석하였을 때 20.47±0.05 mm로 가장 작게 측정되었다(p<0.05). 마찬가지로 최대강도투사법 중 시상면에서 20:80으로 희석하였을 때 20.39±0.08 mm로 가장 작게 측정되었다(p<0.05). 희석비율과 측정 크기의 상관성 분석에서는 모든 재구성 영상에서 강한 음의 상관성을 확인하였다(p<0.05). 결론적으로 조영제 희석비율이 높을수록 혈관의 실측을 측정하기 어려우며 이에 대한 원인으로 Blooming 인공물이 있음을 확인하였다. 따라서 실측에 관한 추후 연구에서 본 연구가 기초자료를 제공할 수 있을 것이라 사료된다.

While the classical music had been developed in Europe for a long time, the jazz music has a short time of history, which was started in New Orleans from 1920``s. Even though it has a short time histoty, it has made rapid progress as a representative American music. However, it has influenced various cultures such as classical musics, fine arts, and dances. The main purpose of this thesis is about how the jazz music has influenced piano books which were imported from the U.S.A. Even though the applied musics are very popular these days, I thought this study is very valuable, so that I started. Practically, the applied musics are based on jazz musics. I think the jazzy musics are very essential for pianists who want to understand the various genres of music. In this thesis, the jazz music includes the origin of the black spiritual, ragtime, blues, and power boogie woogie, which were developed from the root of jazz musics. I chose the "Piano Adventureas and Alfred``s Premier Piano book", which was diffisued as a piano book in Korea. And I analysed the piano book from the list of 1st volume to 8th volume. In theresult, this thesis mainly covers the jazz musics around 1920.
