New Alphenix Hi-Def Detector

Visualisation like never before with Canon Medical's first High-Definition (Hi-Def) mode*

The Alphenix interventional systems feature the world’s first high definition (Hi-Def) detector with 76 micron pixel imaging mode. With more than twice the spatial resolution of conventional flat panel detectors (FPD), the Hi-Def detector helps clinicians visualise fine details and anatomical structures, and deploy devices with accuracy and confidence.

 

The unique Hi-Def imaging mode allows you to effortlessly zoom up to 4cm (1.5”) without losing image quality.

Stent-Assisted Coiling

 

Hi-Def imaging provides the highest possible resolution to accurately evaluate stent apposition. Incomplete stent apposition is a risk factor during stent-assisted coiling of wide-necked intracranial aneurysms and can result in a delayed ischemic event post treatment. Hi-Def imaging enhances clinical confidence and improves patient outcomes.

Complete head-end access flexibility

Alphenix floor- and ceiling-mounted C-arms support complex neurology procedures with an unprecedented range of head-end patient access.

 

The Alphenix C-arm is designed to move around you and your patient, so procedures can be performed comfortably, safely and efficiently.

 

Flexible Lateral Isocentre (FLIC) allows the lateral arm of a biplane system to be height adjusted independently, enabling patient anatomy to be kept at isocentre. In a study by Borota and Patz (2017), the use of FLIC led to a 25% reduction in dose, whilst improving ergonomics and range of table heights and increasing angulation ability on the frontal arm1.

WorkRite

Navigate faster with confidence and accuracy

Improved DSA and 2D roadmap with real-time auto pixel shift to automatically correct the position of the mask image due to body motion. Alpha CT can be used to obtain CT-like 3D imaging data from the C-arm. Superimpose this 3D data or prior CT/MR data with the live fluoro display to guide device placement with greater confidence. Comprehensive planning tools, such as cerebral aneurysm analysis allow for quick and intuitive stent sizing and positioning prior to treatment

Dose Tracking System

DTS is a patient-centric model that records the patient’s skin dose in real-time according to c-arm angle, field of view, tube current and imaging mode to give the most accurate demonstration of dose received during an 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. Researchers confirmed that ongoing real-time dose feedback is a critical factor in the successful modification of operator behaviour to reduce radiation dose. *

DoseRite

Spot ROI – Up to 85% Reduction in dose

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.

 

Spot ROI: 

  • Can be positioned anywhere with the Field of View (FOV) 
  • Can be used to significantly reduce dose during fluoroscopic and DA runs 
  • Allows the operator to monitor the position of your guide wire and the surrounding anatomy, at significantly lower dose

DoseRite

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   
  • Last Image Hold (LIH) overlay with live fluoroscopy    
  • Next generation automatic brightness control with scatter correction, providing optimal image quality and clarity where you need it

Image Magnification without Dose Penalty

  • 50% dose reduction compared to geometric magnification
  • Digitally magnify the image display without increasing detector input dose  
  • Increases image display size in real-time during both fluoroscopy and digital acquisition (DA,) offering dose savings compared to traditional FOV magnifications

Initial investigations of a special high-definition (Hi-Def) zoom capability in a new detector system for neuro-interventional procedures

The Hi-Def zoomed images were much preferred over the FPD, indicating the potential to improve endovascular procedures and hence outcomes using such a Hi-Def feature.

Quantitative comparison of Hi-Def and FPD zoom modes in an innovative detector using Relative Object Detectability (ROD) metrics

Due to their higher resolution, high-definition-mode images are sharper and visually preferred compared with the flat panel detector images. The improved imaging provided by the high-definition mode can potentially provide an advantage during neurointerventional procedures.

High-Definition Zoom Mode, a High-Resolution X-Ray Microscope for Neurointerventional Treatment Procedures: A Blinded-Rater Clinical-Utility Study

 

Each of the metrics demonstrated improved performance of the Hi-Def zoom mode over the standard FPD mode in imaging a wide array of objects such as stents, wires, and spheres. Of particular note is the greater performance of the Hi-Def when considering the high spatial frequencies necessary for visualising fine image details of a pipeline stent.
