Abstract

Ubiquitous use of 2D ultrasound (US) is limited by the difficulty in interpretation of images for an untrained operator. We present a solution for operator guidance through visual cues via registration of US to a 3D model. The method is demonstrated on 2D echocardiography data, where we are able to localize the scan plane in relation to the standard planes on the 3D model. Our algorithm operates by pre-processing both the US and CT images to the most basic information- muscle, blood pool - using classification. Subsequently, these labels are registered using the match cardinality metric for binary labeled images. We evaluated our method on four parasternal long-axis and three parasternal short-axis images from different patients. Results show that our system is able to correctly distinguish between the different US standard views and is able to localize the scan on the 3D model, correctly on five out of seven cases.
