AI Technical Summary

Technical Problem

Existing ultrasound transducer positioning and tracking systems are expensive and complex, and a lower-cost improved device and method are needed to achieve positioning and tracking of ultrasound transducers relative to patients.

Method used

An ultrasound transducer assembly is designed, including first and second protrusions located at both ends of the transducer array, which are used to be recessed on the patient's skin and allow the transducer to pivot around a pivot axis, combined with an angle sensor such as an IMU to monitor the tilt and ensure the transducer is stably positioned in the intercostal space.

Benefits of technology

The stable positioning and three-dimensional imaging of low-cost ultrasound transducers in the patient's body are achieved, which improves the accuracy of imaging data, simplifies the reconstruction process, and reduces system complexity.

Abstract

Example embodiments of the described technology provide a device for pivoting an ultrasound transducer. The device may include a body defining a cavity. The cavity may be shaped to receive an end of the ultrasound transducer. The device may also include a first protrusion and a second protrusion. The first protrusion and the second protrusion may each extend longitudinally outward from respective opposing first and second ends of the body. The first and second protrusions may be configured to depress tissue of a patient surrounding an area to be imaged by the ultrasound transducer.
