NUCLEAR MEDICINE DIAGNOSIS DEVICE, IMAGE PROCESSING METHOD AND PROGRAM

Japanese Patent JP2023094592

A

To improve the image quality.SOLUTION: A nuclear medicine diagnosis device according to an embodiment includes a processing circuit. The processing circuit receives attenuation correction data of a subject and a first nuclear medicine image of the subject being the nuclear medicine image including a scattering effect, inputs the attenuation correction data and the first nuclear medicine image to a trained machine learning-based system, and outputs a first scattering base output including data corresponding to the scattering effect in the first nuclear medicine image. The trained machine learning-based system is trained by receiving the input of (1) a training nuclear medicine image including (1a) attenuation correction training data and (1b) the scattering effect as the input data set and (2) a corresponding set of the scattering base training output whose scattering effect is reduced in comparison to the training nuclear medicine image. The first scattering base output includes at least one of (a) the scattering sinogram showing the estimated scattering in the first nuclear medicine image, (b) the set of projections for each angle of scattering, and (c) the scattering correction image whose scattering is reduced in comparison to the first nuclear medicine image.SELECTED DRAWING: Figure 1A
