Abstract
A system and method for extended spectrum ultrasound training using tags placed on animate and/or inanimate objects. The system combines the use of tags, a reader, and a 3-DOF motion tracker to train a user in finding image windows and optimal image views in an ultrasound simulation environment.
Claims20
A system for extended spectrum ultrasound training comprising:
- at least one near field communication (NFC) tag, wherein each tag comprises:
- a first layer indicating a virtual body location corresponding to the at least one NFC tag;
- a second layer hosting NFC hardware;
- and
- a third layer designed to adhere to an object;
- a sensor assembly comprising:
- a NFC reader for identifying the at least one NFC tag;
- and
- a sensor for measuring an angular orientation of the sensor assembly;
- wherein the sensor assembly does not measure translational motion of the sensor assembly;
- a computation engine, comprising:
- a display;
- at least one processor;
- memory;
- and
- at least one program, wherein the at least one program is stored in the memory and configured to be executed by the at least one processor, the at least one program including instructions to:
- receive data from the sensor assembly, wherein the data comprises the angular orientation of the sensor assembly and an identification of the at least one NFC tag;
- determine a location of the NFC tag based on a set of coordinates associated with the identification;
- display a virtual body;
- display a virtual ultrasound probe, wherein the virtual ultrasound probe has an orientation corresponding to the orientation of the sensor assembly, and wherein the virtual ultrasound probe is positioned at the virtual body location corresponding to the NFC tag identified by the sensor assembly;
- and
- generate and display a virtual ultrasound based on the virtual body part and the virtual ultrasound probe.

A method for training practitioners in ultrasound skills, comprising:
- providing a training simulator system, comprising:
- at least one tag;
- a reader to wirelessly read the at least one tag;
- a rotational 3-DOF (three degrees of freedom) motion tracker;
- a display device;
- displaying a virtual body on the display device;
- displaying a virtual ultrasound probe on the display device, wherein the virtual ultrasound probe has an orientation determined by the rotational 3-DOF motion tracker, and wherein the virtual ultrasound probe has a translational position relative to the virtual body determined by the reader identifying a tag;
- displaying an ultrasound scan of the virtual body based on the translational position and the orientation of the virtual ultrasound probe on the virtual body;
- and measuring translational movement of the rotational 3-DOF motion tracker based on a set of coordinates associated with the at least one tag.
