Kertas kerja ini membincangkan kaedah pendaftaran dan superimposisi pokok arteri koronari pada imej SPECT miokardium (Single Photon Emission Computed Tomography). Kita boleh memahami fungsi miokardium dengan lebih mudah berkaitan dengan bentuk pokok arteri koronari. Imej bertindih boleh didapati dengan mudah melalui beberapa penunjuk manual pada angiogram koronari (CAG) diikuti dengan kaedah padanan automatik: Pertama, model bentuk kasar ventrikel kiri dianggarkan dengan menggunakan data SPECT. Model ventrikel kiri 3-D ini ditayangkan pada sepasang imej CAG dwi-satah. Kita boleh mendapatkan dua imej koronari 2-D pada peta bull's eye dengan mengimbas permukaan ventrikel kiri yang diunjurkan pada CAG. Dengan memaksimumkan tahap padanan antara dua imej koronari 2-D, pendaftaran antara CAG dan SPECT dilakukan. Akhirnya imej bertindih diperoleh dengan mengintegrasikan dua imej koronari 2-D dan imej mata lembu SPECT. Kami mengesahkan kaedah kami melalui eksperimen berangka dengan set data buatan dan juga menggunakannya pada dua set data klinikal.

Abstract: This paper deals with a method of registration and superimposition of a coronary arterial tree on a myocardial SPECT (Single Photon Emission Computed Tomography) image. We can grasp the myocardial function more easily in connection with the shape of the coronary arterial tree. The superimposed image is easily obtainable through some manual pointing on coronary angiograms (CAG) followed by an automatic matching method: First, a rough shape model of left ventricle is estimated by using SPECT data. This 3-D left ventricular model is projected on a pair of bi-plane CAG images. We can obtain two 2-D coronary images on bull's eye map by scanning the left ventricular surface projected on CAG. By maximizing a matching degree between two 2-D coronary images, registration between CAG and SPECT is performed. Finally the superimposed image is obtained by integrating two 2-D coronary images and bull's eye image of SPECT. We validated our method by numerical experiments with artificial data set and also applied it to two clinical data sets.
