Abstract
Radiographic images may be produced electronically for diagnostic purposes during radiation therapy by utilizing a portable cart-based electronic portal imaging system wherein a photo-stimulable phosphor screen is mounted on the cart by a manipulable stanchion/arm assembly enabling selective positioning movement of the screen horizontally, vertically, and angularly relative to the cart among various spacial orientations as necessary to subtend the radiation beam. A camera and a computer are mounted on the cart to photographically capture and digitize X-ray images produced by the screen and to remotely transmit such images for diagnostic purposes of confirming and, as necessary, adjusting patient positioning.
