Ultrasound Image Segmentation using Latent Information

Abstract

Ultrasound (US) imaging is widely employed for biometric measurement and diagnosis of internal organs due to its high availability and the fact it does not emit radiation. It is important to segment the objective anatomies from US images for different applications, e.g., extract the bone surface to do registration for preoperative images and real-time US images, visualize the object in 3D and automatically measure the key parameters for diagnosis.

The current learning-based approach often suffers from generalizability over data recorded from different machines and different patients. To address this problem, we want to classify the image features in the latent space; thereby, improving the understanding of anatomies information rather than pixel intensity.
