Canon Medical Systems is preparing to take digital radiography (DR) to the portable realm. The Irvine, CA-based firm is showcasing its work-in-progress CXDI-31 flat-panel DR system at this week's American Healthcare Radiology Administrators conference in Las Vegas.
Functioning much the same way as conventional analog film cassettes, CXDI-31 facilitates portable x-ray imaging, such as for use on stretchers, gurneys, and patient tables, according to Canon. It allows x-rays to be taken from almost any angle without moving the patient to the sensor unit, according to Canon.
CXDI-31 incorporates a flat-panel sensor that includes a scintillator and an amorphous silicon sensor plate. After x-rays pass through the patient to the scintillator, they are converted into light that is read by the amorphous silicon plate, creating a 14-bit digital image. The sensor features a 100-micron pixel pitch, generating images with resolution of approximately 6.5 million pixels in a 9 x 11-inch format, according to the vendor. The system weighs 6.2 pounds and measures less than an inch thick.
Clinical testing of CXDI-31 is underway at the Cleveland Clinic Foundation, and Canon expects to release the system in October. A 510(k) application has been submitted to the Food and Drug Administration for the system, which will cost less than $100,000.
