Title:
撮像システムの回顧的心臓ゲーティングを用いた冠状動脈の石灰化の検出
Document Type and Number:
Japanese Patent JP4487095
Kind Code:
B2
Abstract:
An imaging system which, in one embodiment, includes a timing algorithm which identifies the proper projection data to be used and a modified halfscan image reconstruction algorithm which provides improved image quality along with the benefits of an enhanced temporal response, is described. In an exemplary embodiment, the timing algorithm includes the steps of determining a diastolic period of a patient's heart and corresponding projection data during the diastolic period. The modified halfscan algorithm includes the steps of identifying redundant data and unequally weighting the data. The resulting images are used for coronary calcification detection.
