1. A medical procedure training system for simulating ultrasound imaging and ultrasound-guided medical procedures, the system comprising:
- a control device;
a graphical interface connected to the control device providing a plurality of interface sections, wherein a first interface section displays a digital video and a second interface section displays a virtual anatomical model and a three-dimensional ultrasound probe model, wherein the digital video comprises images previously recorded by scanning a live subject and correlated to the virtual anatomical model; and
a user input device connected the control device, the user input device comprising an inertial sensor, wherein the graphical interface displays dynamic images corresponding to signals provided by the user input device, the signals corresponding to a spatial orientation of the user input device in relation to an area of examination, wherein the system is configured to simulate ultrasound imaging and ultrasound-guided medical procedures through system feedback.

17. A method of operating a multimodal medical training system, comprising the steps of:
-
selecting a first simulated medical procedure from a library; displaying images on a graphical interface, wherein the images correspond to the simulated medical procedure; receiving a first input from a first user input device, wherein the first user input device is an inertial sensor; processing the first input in relation to the simulated medical procedure; modifying images corresponding to the first user input device, the first user input device images comprises images previously recorded by scanning a live subject, the images corresponding to a position, an angle, and movement of the inertial sensor; receiving a second input from a second user input device, wherein the second user input device is a force-feedback device simulating a medical tool; processing the second input in relation to the simulated medical procedure; modifying images corresponding to the second user input device; providing force-feedback signals to the second user input device; receiving input from the second user input device based upon the force-feedback signals; and determining whether the simulated medical procedure reached a desired end point. - View Dependent Claims (18, 19)
