Title:
フォトンカウンティングマルチビン検出器からのエネルギー分解画像データに基づく画像再構成
Document Type and Number:
Japanese Patent JP6585182
Kind Code:
B2
Abstract:
There is provided a method of image reconstruction based on energy-resolved image data from a photon-counting multi-bin detector or an intermediate storage. The method includes processing (S1) the energy-resolved image data by performing at least two separate basis decompositions using different number of basis functions for modeling linear attenuation, wherein a first basis decomposition is performed using a first smaller set of basis functions to obtain at least one first basis image representation, and wherein a second basis decomposition is performed using a second larger set of basis functions to obtain at least one second basis image representation. The method also includes reconstructing a first image based on the at least one first basis image representation obtained from the first basis decomposition, and combining the first image with information representative of the at least one second basis image representation.
