Abstract

Endoscopic and laparoscopic ultrasound are imaging modalities often used in diagnosis, biopsy guidance, and interventional procedures in the torso Our Image Registered Laparoscopic (Gastroscopic) UltraSound (IRLUS or IRGUS) systems provide contextual information that complements and reinforces both the positioning of the ultrasound probe and the identification of features in ultrasound images, thereby assisting the clinician in establishing and understanding the primary ultrasound image. Pre-procedure CT and ultrasonic probe tracking are used to create synthetic displays based on the position of the probe tip; these are implemented in real time using recent advances in miniaturized position tracking technology. From a series of experiments in a porcine model, we have established that simple real-time tracking with occasional image translation corrections sufficed to give a clinically useful display of comparison images for feature identification and confirmation in laparoscopic and endoscopic ultrasound systems. The combination of global orientation in a sparse 3D model and direct comparison with an oblique slice of 3D data, which corresponded to the ultrasound image, provided an easily learned and effective environment to assist probe positioning and image interpretation. The system provided greater benefits to the clinician in improving the operator kinematics characteristics for laparoscopic over those provided for endoscopic ultrasound. It is anticipated that these systems will find utility in many diagnostic and therapeutic procedures.
