Compact x-ray image scanning system with improved resolution
The patent US12044637B2 describes a system and process for readout-scanning of photostimulable storage phosphor plates that have been previously exposed to X-ray images. Central to this innovation is a scan-head that incorporates an array of light-emitting diodes (LEDs), an imaging array, and a sensor, all positioned on the same side of the phosphor plate. The LEDs are oriented at a predetermined angle, typically less than 45 degrees, to directly illuminate a specific portion of the plate, stimulating the emission of image photons. These photons are then captured by the imaging array, which forms the X-ray image on the sensor, potentially a CMOS sensor. The design allows for a compact scan-head with a height of 13 mm or less, facilitating efficient scanning of the phosphor plate.
Additionally, the system may include features such as filters between the imaging array and the sensor, reflective surfaces to enhance light emission, and a microlens array for improved imaging. The LEDs are designed with individual dome lenses to focus emitted light effectively, and they are spaced approximately 1.0 mm apart. The scanning process involves translating the scan-head across the phosphor plate, repeating the illumination and imaging steps until the entire plate is read. This innovative approach aims to enhance the efficiency and quality of X-ray image readout from photostimulable storage phosphor plates.
