Abstract
One embodiment provides an apparatus for registering a two dimensional (2D) ultrasound (US) frame and a three dimensional (3D) magnetic resonance (MR) volume. The apparatus includes a first deep neural network (DNN) and an image fusion management circuitry. The first DNN is configured to determine a 2D US pose vector based, at least in part, on 2D US frame data. The image fusion management circuitry is configured to register the 2D US frame data and a 3D MR volume data. The registering is based, at least in part, on the 2D US pose vector.
