摘要：
The invention provides a method for improving image quality. Through applying variation value during operation of iterated algorithm, this invention can reduce blur phenomenon caused by partial volume effects and improve image accuracy. In an embodiment, by applying the algorithm utilized in the method for improving image quality, this invention further provides an imaging system to detect the distribution of the object, thereby obtaining a clear restored image corresponding to the radiation source.本發明提供一種影像品質的改善處理方法供醫學影像使用。本發明透過一函數變量應用於影像復原的演算法中,改善會導致影像模糊化之部份體積效應(partial volume effects,PVE)現象,增進影像定量的準確性。在一實施例中,利用該影像品質的改善處理方法,本發明更提供一種造影系統用來檢測待測物,進而得到關於病灶部位之清晰還原影像。3‧‧‧斷層造影系統30‧‧‧斷層造影裝置31‧‧‧偵檢模組32‧‧‧中空區域33‧‧‧移動台34‧‧‧控制單元35‧‧‧儲存單元
