Sparse Ultrasound Image Reconstruction From a Shape-Sensing Single-Element Forward-Looking Catheter.

Objective: Minimally invasive procedures, such as intravascular and intracardiac interventions, may benefit from guidance with forward-looking (FL) ultrasound. In this work, we investigate FL ultrasound imaging using a single-element transducer integrated in a steerable catheter, together with an optical shape sensing (OSS) system. Methods: We tested the feasibility of the proposed device by imagi...
