Simulation of Arbitrary Level Contrast Dose in MRI Using an Iterative Global Transformer Model

no code implementations22 Jul 2023 Dayang Wang, Srivathsa Pasumarthi, Greg Zaharchuk, Ryan Chamberlain

In this work, we formulate a novel transformer (Gformer) based iterative modelling approach for the synthesis of images with arbitrary contrast enhancement that corresponds to different dose levels.

One Model to Synthesize Them All: Multi-contrast Multi-scale Transformer for Missing Data Imputation

no code implementations28 Apr 2022 Jiang Liu, Srivathsa Pasumarthi, Ben Duffy, Enhao Gong, Keshav Datta, Greg Zaharchuk

In this work, we formulate missing data imputation as a sequence-to-sequence learning problem and propose a multi-contrast multi-scale Transformer (MMT), which can take any subset of input contrasts and synthesize those that are missing.
