The new device supports full-size (app. 17 in x 17 in) wireless DR imaging2. Not only is the device ideal for imaging using various techniques and the imaging of various parts of patients' bodies, thanks to its superbly portable design, it can be used in a wide range of scenarios, thus reducing the workload of operators.

In addition, the CXDI-RF Wireless B1 features Canon's new Built-in AEC3 Assistance technology announced today in a separate press release by the company. With this technology, the device's X-ray image sensor is comprised of pixels that can either generate images or detect in real time the pixel value4 corresponding to emitted X-rays. The CXDI-RF Wireless B1 is the world's first DR device possessing this technology to receive marketing approval5.

Among the various DR imaging techniques including fluoroscopy, in which barium moves through a patient's body while either emitting X-ray pulses or continuous X-ray to serial imaging, throughout which x-ray contrast differences are read in real-time on a monitor; and general x-ray imaging of such parts of patients' bodies as the chest, abdomen, bones and joints.

The CXDI-RF Wireless B1 is capable of performing a wide range of techniques including these. What's more, the device weighs approximately 3.5kg and realizes a design that ensures it may be easily carried, enabling operators to easily hold the device during imaging in position or carry it with them using only one hand. Using the dedicated control software, captured images are quickly displayed, making possible faster image checking and support for a wide range of workflows.

With conventional radiography systems, the X-ray imaging device employs a separate, externally attached device for detecting electrical current corresponding to emitted X-rays in order to manage patients' radiation dosages. However, Built-in AEC Assistance technology used by the CXDI-RF Wireless B1 utilizes the pixels in the device's X-ray image sensor to generate images while simultaneously detecting in real time the pixel value corresponding to emitted X-rays. Thanks to this new technology, there is no longer a need for an external AEC sensor for the radiography stand or table, thus supporting the needs of professionals in clinical environments where external AEC sensor may not be usable.

Canon will commence sales of the CXDI-RF Wireless B1 from late August 2021.

  • 1DR systems employ a scintillator that converts X-rays into visible light, and a large-scale flat-panel sensor to use the light to generate a digital image.
  • 2When in wireless operation, only general imaging is available.
  • 3AEC stands for "Automatic Exposure Control".
  • 4A digital value read by the image sensor after photoelectric conversion of X-rays into visible light by way of a scintillator.
  • 5Among DR X-ray imaging systems for fluoroscopy or general radiography. The device has received approval based on the Japanese Pharmaceutical and Medical Device Act (Authorization number: 302ABBZX00058000). As of February 24, 2021. For more information about this technology, please click here.
