Abstract
A scan head design uses 1:1 (one-to-one) imaging micro-lens arrays to transfer the object plane X-ray image from a CR-plate onto a linear photosensor. The scan-head includes a housing having therein, an array of red light emitting diodes (LEDs), a microlens array, and a sensor. The housing faces the CR-plate and the scan-head is translated across the CR-plate to read out the X-ray image therein. The scan head is compact and provides for improved spatial resolution and reduced power requirements.
