METHOD FOR CREATING IMAGE INFORMATION, METHOD FOR CREATING TOMOGRAPHIC IMAGE INFORMATION FOR TOMOGRAPHIC PHOTOGRAPHING APPARATUS, AND TOMOGRAPHIC PHOTOGRAPHING APPARATUS

摘要

PROBLEM TO BE SOLVED: To allow acquirement of clearer emission image information in a short time, targeting regions activated under the effect of breathing and heartbeat.;SOLUTION: In this method for creating image information, a radiation detector detects first gamma rays generated inside the body due to a PET medical agent and second gamma rays radiated from a gamma ray source to go through the body. Each information obtained from the detected first gamma rays is used to respectively create emission image information (E image information) E₀, E₁, and E₂ for each of body motion topological sections 0, 1, and 2 obtained by dividing the heartbeat and a breathing period. Each information obtained from the detected second gamma rays is used to respectively create transmission image information (T image information) T₀, T₁, and T₂ for each of the body motion topological sections 0, 1, and 2. Relative displacements F₁₀ and F₂₀ are obtained by respectively superimposing the T image information T₁ and T₂ on the T image information T₀. The relative displacements are used to superimpose the E image information E₁ and E₂ on the E image information E₀.;COPYRIGHT: (C)2010,JPO&INPIT
