Canon Presents X-Ray Sensor With Auto-Exposure Control

Canon announces the new "Built-in AEC assistance" technology for digital radiography. With this technology, the device's X-ray image sensor uses real-time detection of the pixel value corresponding to emitted X-rays, notifying the X-ray generator when pixel value reaches a preset value.

In clinical environments, X-ray imaging is conducted with various precautions in accordance with the ALARA (As Low As Reasonably Achievable) principle of radiation safety, which states that the use of radiation must, among other factors, "take into account benefits to the public health and safety, and other societal and socioeconomic considerations." The AEC technology enables operators to specify a pixel value and automatically send a notification to the X-ray generator. When that value is reached, eliminating the need for a dedicated external attachment and enabling the automatic stopping of X-ray emissions from the X-ray generator.
