Title:
IMAGE PROCESSING DEVICE AND IMAGE PROCESSING METHOD
Document Type and Number:
Japanese Patent JP2020128882
Kind Code:
A
Abstract:
To provide a device capable of generating a tomographic image from which noise is removed with high performance based on list data collected by a radiation tomography apparatus.SOLUTION: An image processing device 10 includes a first image generation section 11, a second image generation section 12, and a CNN processing section 13. The first image generation section 11 generates a first tomographic image Dof an m-th frame by using a data group included in the m-th frame in list data. The second image generation section 12 generates a second tomographic image Sby using a data group where the number of data is greater than that of the data group used in generating the first tomographic image Din the first image generation section 11 in the list data. The CNN processing section 13 allows a CNN to receive an input of the second tomographic image Sand allows an output tomographic image Oto be output from the CNN, allows the CNN to perform learning based on comparison between the output tomographic image Oand the first tomographic image D, and repetitively performs a learning operation so as to generate an output tomographic image Owhenever learning is performed.SELECTED DRAWING: Figure 1
