Interventional Cardiology ImagingRite

ImagingRite, a comprehensive suite of imaging tools offered with Alphenix angiographic systems, was designed to assist clinicians in optimising their workflow and image quality (IQ) during interventional procedures. Interventional cardiology procedures can be challenging due to the complexity of the cardiac anatomy, function, pathology, the fine size of the vasculature, cardiac motion, and the required treatment accuracy. With our ImagingRite technology, Canon Medical Systems offers optimum image quality at reduced dose. Our advanced software enables clinicians to plan, visualise, guide, treat and verify. Canon Medical Systems’ ImagingRite advanced applications give clinicians the tools they want to obtain the images they need during challenging interventional procedures including angioplasty, atherectomy, valvuloplasty, and transcatheter valve placement.

Advanced Imaging Applications

A suite of tools, allows clinicians to plan, see and guide through the process of preparing for and conducting the patient intervention. Combined with Vital’s Vitrea™ software, clinicians have the tools to help guide them through the intervention, including:
  • 3D Digital Angiography (3D DA) and 3D Digital Subtraction Angiography (3D DSA)
  • 3D Roadmap (3DRM) and Multi-Modality Fusion (MMF)
  • Alpha CT imaging – Cone Beam CT
  • Needle Guidance
  • Heart and coronary Analysis Software
  • Left Atrium Auto Segmentation Software

Alpha CT Vessel

C-arm rotation with high acquisition rates can be used to generate 3D reconstructed volumes of vascular anatomy. The 3D vessel can be rotated in any direction to provide clinicians with additional views of vascular anatomy to aid them in their diagnosis and treatment during interventional procedures. Multiple views obtained by a 3D rotational image enable clinicians to visualise vascular anatomy such as areas of stenosis, the take-off of an abnormal vessel, the feeder vessel to a vascular malformation, as well as various other pathologies. Clinicians can use these additional views to aid them during device manipulation.


The C-arm rotates around the patient twice for 3D DSA acquisition protocols. The first spin is acquired without contrast, and the second one with the injection of contrast. The data acquired from the two spins are automatically subtracted, removing bones throughout the entire rotation. As a result, the 3D DSA reconstructed volumes depict only the contrast filled vascular anatomy. The rotational data can be reconstructed with various processing techniques to depict bones, tissue, devices, as well as vascular anatomy. In conjunction with the Vitrea workstation, multiple injections of vessels can be fused together to help clinicians outline various vascular anomalies.

Volume Navigation

Real-time volume navigation 3DRM with the Alphenix system links every movement of the C-arm and table position with the fused 3D volume and fluoroscopic display. Regardless of changes in table position, Source-Image-Distance (SID), Field-of-View (FOV) or C-arm angulation, the 3D overlay remains consistently aligned with the fluoroscopic image provided.


Using Vital software analysis tools, a 3D enhanced image previously acquired by CT, MRI or an angiographic system can be superimposed and displayed with live fluoroscopy.

Alphenix Left Atrial (LA) Auto Segmentation Feature

CT or MR cardiac volume data imported into the angio-workstation can be automatically segmented to view the left atrium of the heart. The segmented LA image is then overlaid on live fluoro image and manually registered to the fluoro anatomy. The fused image provides clinicians with an overlay of a 3D view of the vascular anatomy and the 2D angio image displaying the catheter. When the C-arm rotates, the transparent volume image rotates as well.

Alpha CT

Cone-beam CT scans are derived from C-arm rotational acquisitions. The 3D reconstructed volumes can be transferred to viewing workstations. Volume Rendering (VR), Maximum Intensity Projection (MIP), Multi-Planar Reformations (MPR), axial, sagittal, and coronal views, may be used to visualise the target anatomy/pathology during interventional procedures, such as left atrial appendage, lung for pneumo- or hemo- thorax, and pericardial effusion.
Alphenix includes several processing capabilities that can be used with Alpha CT:

Conventional Imaging in Interventional Cardiology

2D Coronary Rotation

Imaging with 2D coronary rotation, perform a single injection and let the C-arm rotate to capture key diagnostic views of coronary arteries. Using this technology enables clinicians to obtain optimum image quality at reduced dose as compared to traditional multi-acquisition imaging to acquire similar views. Automated sequential rotational image acquisition aids clinicians in prioritising safety and efficiency.

Dynamic Trace (DT)

Dynamic Trace gives clinicians the ability to perform a digital acquisition while panning the table following the flow of contrast. This image is an example of panning from hip to foot.
DT is a digital acquisition method used in a panning mode to enhance vascular imaging by increasing background compression and reducing the presence of bones. Perform contrast runoffs anywhere in the body with ‘DSA-like’ effects.

The Alphenix systems also feature comprehensive dose management tools, called DoseRite, including Canon Medical Systems’ exclusive Spot Fluoroscopy, Live Digital Zoom, Advanced Image Processing (AIP) with Illuvis, variable dose modes and rates, fluoro record and store, and Dose Tracking System (DTS), enabling clinicians to obtain optimum image quality at reduced dose.

Spot Fluoroscopy

Spot Fluoroscopy provides asymmetric collimation anywhere within the field of view resulting in a lower dose than conventional collimation. The ROI can be precisely sized and positioned almost anywhere vs. just centered when using conventional collimation, providing the clinician with the exact view desired. Clinicians can observe a smaller region of anatomy while viewing the Last Image Hold (LIH) surrounding the area.
Spot fluoroscopy ROI can be easily sized and positioned anywhere in the FOV and provides anatomical landmarks visible in the LIH.

Live Digital Zoom

Live Digital Zoom enhances image visualisation by increasing image display size in real time during both fluoroscopy and digital acquisitions, offering potential dose savings compared to traditional FOV magnifications. A range of zoom modes from 1.2 to 2.4 times can be applied to any of the system magnification modes.


AIP uses SNRF technology to lower dose dramatically by analysing and processing each image frame in real time during fluoroscopy.
AIP enhances visibility by increasing image contrast, enhancing small object detail and reducing halation from lung fields. SNRF reduces total noise power by up to 90 percent while maintaining sharp spatial and temporal resolution.1 In concert, these unique technologies combine to provide image quality improvements greater than 200 percent.2 This has resulted in demonstrated reduction to both patient and staff radiation dose levels by more than 50 percent with utilisation of lower frame rates and more fluoroscopy as compared to higher dose digital “cine” acquisitions.3

Dose Rates

The Alphenix makes possible industry-leading dose rates. No other system comes close to providing as much flexibility with nine variable frame rates (1, 2, 3, 5, 7.5, 10, 15, 20, 30) and four programmed fluoroscopy modes (low, middle, normal, high), which are standard on every Alphenix system. Different combinations of pulse rates, dose levels and system parameters are available to enable clinicians to optimise dose rates and image quality for various study protocols.

Fluoro Record

Fluoro record and fluoro store is incorporated into the standard practice and can be used to replace digital acquisition (DA) for interventions as well as groin shots resulting in significant dose reduction.
