Isotropic Volume Reconstruction from Multiple 2D Scans Using Super -Resolution Techniques

摘要

A computer-implemented method for performing isotropic reconstruction of Magnetic Resonance Imaging (MRI) data includes receiving a stack of slices acquired by an MRI device in two or more directions and reslicing the stack of slices into (i) an acquired view stack comprising high-resolution slices acquired in-plane, and (ii) a reslice stack comprising degraded slices acquired out of plane. An estimated slice profile is generated based on the stack of slices and the acquired view stack is convolved with the estimated slice profile to yield a simulated distorted slice stack. The simulated distorted slice stack is subtracted from the acquired view stack to yield a high-frequency band estimate and the high-frequency band estimate is combined with the reslice stack to yield isotropic reconstruction results.

1. A computer-implemented method for performing isotropic reconstruction of Magnetic Resonance Imaging (MRI) data, the method comprising:
receiving a stack of slices acquired by an MRI device in two or more directions; reslicing the stack of slices into:
an acquired view stack comprising high-resolution slices acquired in-plane, anda reslice stack comprising degraded slices acquired out of plane; generating an estimated slice profile based on the stack of slices; convolving the acquired view stack with the estimated slice profile to yield a simulated distorted slice stack; subtracting the simulated distorted slice stack from the acquired view stack to yield a high-frequency band estimate; and combining the high-frequency band estimate with the reslice stack to yield isotropic reconstruction results.
