Synthesizing cardiac MR images from sketches (MIDL 2024)

cHeartFlow: Synthesizing Cardiac MR Images from Sketches — Xinrui Zu, Qian Tao. MIDL 2024. [Paper]

We present contrastive HeartFlow (cHeartFlow), a generative framework that synthesizes cardiac magnetic resonance (CMR) images from simple sketches by training on contrastive pairs of images and sketches.

cHeartFlow generation compared with GAN-based and diffusion-based models.
cHeartFlow generation compared with popular GAN-based and diffusion-based models.

Zero-shot MRI registration with cHeartFlow trades off registration accuracy (faithfulness) against image quality (realism). Below: (1) original MRI cycle, then registration at control parameter t = 0.25 / 0.5 / 0.75.

Original MRI cycle.
Registration at t=0.25.
Registration at t=0.5.
Registration at t=0.75.
