AI Technical Summary

Technical Problem

In existing technologies, imaging X-ray equipment suffers from insufficient accuracy in locating virtual patient models, especially in the coordinate system of the imaging X-ray equipment, which makes it difficult to accurately locate the patient model and leads to inaccurate dose information calculation.

Method used

A trained position determination function is used to automatically locate a virtual patient model based on the patient's X-ray images using machine learning methods. The position of the patient model in the X-ray equipment coordinate system is determined by analyzing the X-ray images through a convolutional neural network (CNN) and an encoder, thus avoiding the need for additional sensor technology.

Benefits of technology

It achieves accurate positioning of the virtual patient model in the X-ray equipment coordinate system, improves the accuracy of dose information calculation, reduces user errors, saves time, and does not require additional hardware equipment.
