AI Technical Summary
Existing CT scanners face challenges in properly positioning patients for brain scans, leading to unnecessary radiation exposure of the eyes due to non-compliance with anatomical guidelines, particularly when using 2D surview scans.
A CT scanner system with a camera system and controller that performs a low-dose 3D scout scan to detect patient head position and orientation, allowing for automatic analysis and adjustment of the field of view to exclude the eyes, using gantry tilt or patient repositioning to ensure optimal brain coverage without irradiating the eyes.
Reduces radiation exposure to the eyes by accurately determining the field of view through a two-stage process, ensuring compliance with anatomical guidelines and providing a final field of view that excludes the eyes, even in cases where gantry tilt is not available.
