Haptic Pulse Simulation for Virtual Palpation
نویسندگان
چکیده
In this paper we propose a software-based approach to simulate the haptics of the human pulse. This effect can then be interactively explored by virtual palpation. The algorithm features a flexible, userdefined setup. In addition the simulation takes dynamic parameters into account and allows for many different use cases.

An Image-based Multiproxy Palpation Algorithm for Patient-Specific VR-Simulation
Palpation is the first step for many medical interventions. To provide an immersive virtual training and planning environment, the palpation step has to be successfully modeled and simulated. Here, we present a multiproxy approach that calculates friction and surface resistance forces for multiple contact points on finger tips or virtual tools like ultrasound probes and displays the resulting f...

Surgical training systems based on virtual reality (VR) and simulation techniques may represent a more cost effective and efficient alternative to traditional training methods. Additionally, VR is a technology that can teach surgeons new procedures and can determine their level of competence before they operate on patients. At Forschungszentrum Karlsruhe, a virtual reality training system for m...
متن کاملDynamic touch-enabled virtual palpation
Palpation is an important method of feeling with hands during a physical examination, in which the doctor presses on the surface of the patient body to feel the organs or tissues underneath. In current surgical simulation systems, the lack of an effective sense of touch is still a major problem. In this paper, a dynamic touch-enabled virtual palpation model is proposed. The palpation force sens...
متن کاملA Mixed Reality Simulator for Feline Abdominal Palpation Training in Veterinary Medicine
The opportunities for veterinary students to practice feline abdominal palpation are limited as cats have a low tolerance to being examined. Therefore, a mixed reality simulator was developed to complement clinical training. Two PHANToM premium haptic devices were positioned either side of a modified toy cat. Virtual models of the chest and some abdominal contents were superimposed on the physi...
متن کاملDeveloping the 'Ouch-o-Meter' to Teach Safe and Effective Use of Pressure for Palpation
Many clinical examinations involve palpation and part of the diagnostic process depends on the application of pressure. Teaching and learning such skills is difficult especially for internal examinations. A modification to a veterinary virtual reality (VR) simulator, the Haptic Cow, was planned to teach safe and effective use of pressure for bovine pregnancy diagnosis. Expert technique was capt...
