Title:
MEDICAL IMAGING DEVICE, IMAGE PROCESSING METHOD, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2018/155046
Kind Code:
A1
Abstract:
This medical imaging device is designed to perform compressive sensing, and reduces the time for reconstruction processing while maintaining the quality of images. The medical imaging device is provided with: an image reconstruction unit for reconstructing an image by iterative optimization computation for compressive sensing; and a basis selection unit for selecting a basis transformation for optimization for each iteration. The basis selection unit may select a basis on the basis of a predetermined sequence of bases or may select a basis using weight coefficients preset for the bases. The present invention can be applied to medical imaging devices such as MRI devices, ultrasound imaging devices, and CT devices.
