Increased confidence for you and your patients

Interventional departments have a responsibility to take every effort to reduce radiation dose to patients as well as the occupational dose received by staff.

Canon Medical for over 25 years have facilitated a steady decline in radiation dose with the launch of pioneering products and technologies that expand our commitment to dose reduction.

The new Alphenix family of interventional systems, equipped with our DoseRite technologies, provide a comprehensive suite of dose management solutions to significantly reduce radiation doses without compromising clinical confidence and workflow.

Prioritise lower radiation doses for your patients and staff with DoseRite.

“Dose reduction is now a top priority everywhere in the guidelines, but how to achieve it is not always at hand. All the tools that have been made available to us with Alphenix Core + have been very useful to improve the overall safety of our procedures radiation-wise - Spot ROI and Live Zoom, but also sound alerts and the very intuitive dose tracking system.

Dose Tracking System - Visualise skin dose in real-time

DTS is a patient-centric model that records the patient’s skin dose in real-time according to imaging parameters and geometry to provide an accurate demonstration of the dose received during and examination.

Real-time dose monitoring and visualisation allows the operator to modify their approach during procedures to avoid regions where dose thresholds could be exceeded.
A study by The St George Hospital found that use of advanced Dose Reduction Technology (DTS) resulted in a 46% reduction in peak skin dose during coronary stent insertion. Researchers confirmed that ongoing real-time dose feedback is a critical factor in the successful modification of operator behaviour to reduce radiation dose. *

Dose Report - See radiation exposure like never before

Summary dose reports provide a record of estimated peak skin dose and dose parameters, including snapshots of skin dose distribution.

All patient DTS data can be easily exported and referenced during subsequent procedures, to ensure that regions of previous high exposure can be avoided.


Spot Fluoro - Reduce scatter radiation by up to 50% with advanced collimation

See a more complete picture with less dose to surrounding anatomy. Spot Fluoro enables the operator to collimate a rectangular or square region of interest (ROI) anywhere within the general field of view.
  • Reduce cumulative dose area product by up to 50%**  
  • Reduce scatter radiation by more than 50%**, enabling safer procedures for patients and interventional staff  
  • Freely collimate anywhere on the image with asymmetric blade movements   
  • LIH overlay with live fluoroscopy   
  • Next generation automatic brightness control with scatter correction, providing optimal image quality and clarity where you need it

Spot ROI - Real-time picture in picture

The unique Spot ROI collimator filter allows the operator to reduce dose to surrounding anatomy while simultaneously ensuring full image quality in the area that matters most. This allows operators to always position the ROI over the vascular structure of interest, independently of its location with the FOV.

  • Can be positioned anywhere with the Field of View (FOV)
  • Spot ROI can be used to significantly reduce dose during fluoroscopic and DA runs
  • Monitor the position of your guide wire and the surrounding anatomy, significantly reducing patient skin dose

Dose reduced by 65-85%

"Spot ROI helps us reduce radiation dose to our patients (and staff). Its use of a filter that is introduced into the beam with an aperture means we can maintain the image quality we want at the point of treatment but the surrounding field of view with catheter tip and guide wire tip can still be seen at a dose that is reduced by 65-85%. "

Spot Region Of Interest Imaging: A Novel Functionality Aimed At X-Ray Dose Reduction In Neurointerventional Procedures 

…a combination of the use of Spot F and Spot ROI, depending on the clinical situation, is a potentially useful technique for obtaining an appropriate quality of visual information while reducing the radiation dose received by the patient.

Real-time colour pictorial radiation monitoring during coronary angiography: effect on patient peak skin and total dose during coronary angiography

The DTS is simple to use and results in a substantial reduction of patient peak skin and total radiation dose. The greatest gains from DTS are evident during stent insertion, where the patient is exposed to the highest radiation risk.
