AI Technical Summary
Technical Problem
During cerebral angiography or treatment, changes in the patient's head posture require doctors to manually adjust the C-arm angle and bed position multiple times, increasing the risk of radiation exposure for both patients and doctors.
Method used
By estimating head pose based on initial facial images and converting it into virtual and real head spatial data, the movement of medical imaging equipment can be controlled for precise positioning, reducing the number of fluoroscopic examinations.
Benefits of technology
It significantly reduces the risk of radiation exposure for patients and physicians, and improves the safety and accuracy of medical imaging.

Abstract
This invention relates to the field of medical imaging technology, and discloses an auxiliary head positioning method, device, equipment, and storage medium. First, head posture estimation is performed based on an initial facial image, enabling timely acquisition of virtual head spatial data. Then, the virtual head spatial data is transformed to obtain real head spatial data. Finally, based on the real head spatial data and preset head spatial data, the movement of the medical imaging equipment is precisely controlled for head positioning, allowing doctors to select and track the optimal imaging angle for angiography or treatment more accurately and efficiently. This implementation significantly reduces the number of fluoroscopy sessions for patients during imaging, thereby effectively reducing the radiation exposure risk for both patients and doctors. This precise control and real-time feedback capability will improve the safety and accuracy of medical imaging.
