AI Technical Summary

Technical Problem

Current clinical TCD physician training relies on direct hands-on practice with patients, which can lead to inaccurate test results and medical risks due to lack of proficiency. Furthermore, the lack of dedicated simulation training models makes it impossible to evaluate the accuracy of physician operations, thus limiting the popularization and application of TCD technology.

Method used

A transcranial Doppler (TCD) simulation training model for intracranial blood vessels was designed, including a peristaltic pump to simulate the heartbeat and blood supply, a head model to simulate the cranial cavity and blood vessels, and a simulation of normal and diseased blood vessels through Doppler ultrasound detection. Adjustable methods for simulating vascular stenosis are adopted, such as changing the diameter of the vessel, physical compression, airbag compression, and precision control, to realize the simulation of blood flow and stenosis.

Benefits of technology

It provides a risk-free, standardized training environment, allowing doctors to practice and evaluate their skills repeatedly, improving operational accuracy and diagnostic consistency, shortening the doctor's professional development cycle, and meeting the clinical demand for professional TCD ultrasound doctors.
