Canon develops new technology for DR control software that utilizes AI technology to reduce digital radiography image noise by up to 50% compared with Canon’s conventional image processing technology

TOKYO, March 23, 2022—Canon Inc. introduced right this moment that the corporate has developed the brand new “Clever NR” (FDA 510K Quantity: K212269) know-how for the management software program1 for the corporate’s CXDI collection of digital radiography2 (DR) units3.

The CXDI collection of digital radiography units, launched in 1998, was extremely praised by purchasers for its excellent usability and excessive picture high quality. Canon’s newly developed picture processing know-how makes use of deep studying AI know-how to generate photos with decreased picture graininess in contrast with the corporate’s standard noise discount know-how. This new know-how has the potential to assist better-quality diagnoses on the entrance line of medical remedy and make doable high-quality imaging with reduces X-ray dosages for sufferers.

All through Canon’s years of growing DR programs, the corporate has endeavored to scale back the radiation dosage required for digital X-ray imaging whereas on the similar time lowering sign noise in captured photos. A rule-based picture processing algorithm is used with Canon’s current noise discount processing to lower noise by setting up and implementing a algorithm that establish traits of sign noise in X-ray photos. Nevertheless, this methodology is proscribed in its skill to course of noise, and relying on the realm of the affected person being examined in addition to different circumstances, makes an attempt to right picture graininess has resulted in photos of the topic which can be much less sharp.

Clever NR relies on Canon’s proprietary AI know-how that makes use of deep studying and has been skilled utilizing roughly 3,000 X-ray photos obtained over the course of the corporate’s lengthy historical past of growing the CXDI collection of scientific imaging. Utilizing these photos, the know-how utilized machine studying to acknowledge the distinctive traits of sign noise4. In consequence, sign noise has been decreased in comparison with current applied sciences and the effectivity of sign noise removing—a discount of as much as 50%5—has been elevated whereas sustaining the extent of sign energy required for imaging.

Going ahead, Canon will proceed growing its Clever NR know-how as a devoted software program possibility for its CXDI collection of DR programs.

  • 1Paid software program that shows photos captured by CXDI-series DR programs on a PC or different terminal. Clever NR is suitable with CXDI Management Software program v.3.10 and above.
  • 2DR programs make use of a scintillator that converts X-rays into seen mild, and a large-scale flat-panel sensor to make use of the sunshine to generate a digital picture.
  • 3Suitable units: CXDI-710C Wi-fi, CXDI-810C Wi-fi, CXDI-410C Wi-fi (all fashions launched in July 2017).
  • 4Clever NR makes use of AI know-how on the design stage of sign noise discount processing. The product itself doesn’t be taught with AI from acquired photos.
  • 5Based mostly on Canon analysis evaluating Canon CXDI Management Software program v2.19.2 earlier than and after utility of the image-processing algorithm.
