Real-time three-dimensional ultrasound enables new intracardiac surgical procedures, but the distorted appearance of instruments in ultrasound poses a challenge to surgeons. This paper presents a detection technique that identifies the position of the instrument within the ultrasound volume. The algorithm uses a form of the generalized Radon transform to search for long straight objects in the ...

Every surgeon and nurse involved in surgery builds a mental model of each type of surgery based on their experiences. This implicit knowledge about the surgical workflow allows them to make decisions based on the current context and predict and prepare future steps. Acquiring this model takes time, therefore experienced scrub nurses are in high demand. Additionally to that, qualified scrub nurs...

Automatic visual detection of instruments in minimally invasive surgery (MIS) can significantly augment the procedure experience for operating clinicians. In this paper, we present a novel technique for detecting surgical instruments by constructing a robust and reliable instrument-part detector. While such detectors are typically slow to use, we introduce a novel early stopping scheme for mult...

Abstract The shortage of operating room technicians has led to a growing demand for automated systems in the OR maintain quality care. Robotic scrub nurse (RSN) are increasingly being developed, which perform tasks such as handling instruments and documenting surgery. While research focused on detecting hands surgical staff or recognizing phases, there is lack instrument tray. Therefore, this s...

Detection of surgical instruments plays a key role in ensuring patient safety in minimally invasive surgery. In this paper, we present a novel method for 2D vision-based recognition and pose estimation of surgical instruments that generalizes to different surgical applications. At its core, we propose a novel scene model in order to simultaneously recognize multiple instruments as well as their...

In today's climate of clinical governance there is growing pressure on surgeons to demonstrate their competence, improve standards and reduce surgical errors. This paper presents a study on developing a novel eye-gaze driven technique for surgical assessment and workflow recovery. The proposed technique investigates the use of a Parallel Layer Perceptor (PLP) to automate the recognition of a ke...
