Abstract
Purpose: The brain perfusion SPECT is the examination which is able to know adversity information related brain disorder. But brain perfusion SPECT has also high failure rates by patient's motions. In this case, we have to use two days method and patients put up with many disadvantages. We think that we don't use two days method in brain perfusion SPECT, if we can use registration method. So this study has led to look over registration method applications in brain perfusion SPECT. Materials and Methods: Jaszczak, Hoffman and cylindrical phantoms were used for acquiring SPECT image data on varying degree in x, y, z axes. The phantoms were filled with
Brain의 질병을 평가하는 유용한 검사방법 중의 하나인 brain perfusion SPECT는 환자의 움직임으로 인한 검사의 실패확률이 높아 one day method를 사용하지 못하고 two days method를 사용해야 하는 경우가 많다. 본 연구에서는 image registration을 사용하여 검사의 실패확률을 줄이고 one day method로 검사를 시행할 수 있는지 image registration을 적용할 경우 검사의 신뢰성을 알아보고자 하였다. Jaszczak phantom에 준비된 방사성동위원소
