Abstract
A system and method that improves the speed and efficiency through which ultrasound practitioners acquire and develop essential basic ultrasound skills in a simulated environment without the need of actual patients or subjects. The system utilizes a simulator with an input device that manipulate a virtual transducer probe in a simulated 3D space to cut a slice through a basic shape. A 2D section of the cut plane is also displayed so that the practitioner can learn to relate 2D section with their 3D objects cut in cross-section.
Claims17
A method for teaching practitioners basic ultrasound skills, comprising:
- a. providing a training simulator system, comprising:
- i. an input device to control a virtual ultrasound probe that lets a practitioner determine a position and an orientation of the virtual ultrasound probe proportionate to the position and the orientation of the input device, wherein the input device is a motion-sensing device in the form of a transducer frame that mimics a real ultrasound probe,
- ii. an apparatus containing an object having a basic shape that is scanned by the input device, the basic shape representing an abstraction of an anatomical part;
- iii. a display device comprising a plurality of windows for displaying, during operation, a menu of virtual basic shapes in a first window, a menu of available virtual transducer probes in a second window, the virtual ultrasound probe and a simulated environment in a third window, and a 2D image of a section representing an ultrasound slice in a fourth window;
- b. receiving a user selection of one virtual basic shape from the menu of virtual basic shapes that corresponds with the basic shape of the object within the apparatus, and receiving a user selection of one available virtual transducer probe from the menu of available virtual transducer probes, which corresponds to the input device and the virtual ultrasound probe controlled by the input device;
- c. displaying the virtual ultrasound probe corresponding to the available virtual transducer probe selected and the selected virtual basic shape on the third window of the display device, wherein a scanning plane is emitted from the virtual ultrasound probe through the simulated environment for visualizing a location, a direction, and an orientation of a virtual sound wave;
- d. using the input device in combination with the apparatus to detect the basic shape of the object in the apparatus, wherein the basic shape is selected from a group consisting of cones, conic sections, spheres, cylinders, tubes, crossing tubes, and bifurcating tubes;
- e. receiving instructions from the input device to manipulate the position and the orientation of the virtual ultrasound probe relative to the virtual basic shape to define the ultrasound slice through the virtual basic shape by the scanning plane, wherein movement of the virtual ultrasound probe in three dimensions correlates with movement of the input device in three dimensions;
- and
- f. displaying in the fourth window of the display device simultaneously with displaying the virtual probe on the third window of the display device, the 2D image of a section of the virtual basic shape defined based on the scanning plane as manipulated by the input device.

- iii. display the selected virtual basic shape in the third portion of the display device;
- iv. receive instruction from the input device to manipulate the position and the orientation of the virtual ultrasound probe relative to the virtual basic shape to define an ultrasound slice through the virtual basic shape by the scanning, wherein movement of the virtual ultrasound probe in three dimensions correlates with movement of the input device in three dimensions;
- and
- v. display the 2D image of the section of the virtual basic shape defined by the ultrasound slice in the fourth portion of the display device.
