AlluraClarity with ClarityIQ technology provides high quality imaging for a comprehensive range of clinical procedures, achieving excellent visibility at low X-ray dose levels for patients of all sizes. 18 clinical studies on 3840 patients have been published on the AlluraClarity to date, revealing one truth: there is significantly lower dose across clinical areas, patients and operators.ᵃ

ClarityIQ || Smart image optimization

ClarityIQ for high-quality, actionable images

The powerful image processing technology ClarityIQ incorporates state-of-the-art, real-time image processing, developed by Philips Research and based on state-of-the-art parallel computing technology. Advanced image processing helps tune other aspects of the system, including use of small focal spot, consistent copper filtration, and lower mA tube output. All to give you high quality images to help guide interventions.
AlluraClarity family || Excellent dose management

AlluraClarity family for high quality imaging at low dose

Meet a revolutionary new generation of interventional X-ray systems. The AlluraClarity family provides high quality imaging for a full range of clinical procedures at ultra low dose.
Live Image Guidance || Full suite of clinical applica

Live Image Guidance simplifies procedures and workflow

Simplify procedures and support efficient workflows for a wide range of interventions with Live Image Guidance. Automatic Pixel Shift, Noise Reduction and Image Enhancement contribute to Live Image Guidance for interventional neuroradiology. Live Image Guidance in electrophysiology benefits from the Imaging Enhancements from catheters and ablation devices. Spatial Noise Reduction is used in endovascular interventions to obtain vessel delineation even in areas with bowel movement. And for interventional cardiology, Movement Compensation is the leading parameter.
Fine-tuned parameters || Smart image optimization

Fine-tuned parameters unlock AlluraClarity's full potential

In order to use ClarityIQ technology to its full potential, we have fine-tuned over 500 system parameters (tube, detector, image processing, etc.) for each application area. This allows for superb visualization of coronaries and cardiac wall movements, and through bowel and respiratory movements. For electrophysiology, it means obtaining a superb visualization of the regions of interest and ablation devices. By using Automatic Pixel Shift in DSA and roadmap fluoroscopy, you can obtain enhanced visualization of neuro vasculature.
Ultra low dose imaging || Excellent dose management

Ultra low dose imaging expands treatment options

As interventions become increasingly complex, your challenges multiply. One challenge is the growing number of patients with a high BMI. Visualizing their anatomy can necessitate increased dose levels and lengthen fluoroscopy time. AlluraClarity's ultra low dose imaging takes on that challenge. Expand your treatment options even with obese and high-risk patients.
Real-time Pixel Shift || Smart image optimization

Real-time Pixel Shift reduces motion artifacts

By aligning images with each other before subtraction, Real-time Pixel shift helps reduce motion artifacts.
Motion Compensation || Smart image optimization

Motion Compensation reduces motion blur

ClarityIQ can now apply motion compensation to temporal filtering algorithms, to reduce image blur in high-motion areas of anatomy.
Advanced Spatial Filtering || Smart image optimization

Advanced Spatial Filtering reduces noise

ClarityIQ uses advanced spatial filtering to highlight structures and reduce the impact of background noise in an image. High-speed, parallel computing architecture enhances filtering in real time.
Image Enhancement || Smart image optimization

Image Enhancement optimizes images for clinical application

This module of ClarityIQ optimizes the presentation of the image based on clinical application and user taste. Contrast, brightness, and edge enhancement are some of the many variables that are optimized.

  • c) The results of the application of dose reduction techniques will vary depending on the clinical task, patient size, anatomical location and clinical practice. The interventional radiologist assisted by a physicist as necessary has to determine the appropriate settings for each specific clinical task.
  • d) Results based on total dose area product from a single center retrospective, historically controlled cohort study on 614 patients (302 for Allura Xper without ClarityIQ and 312 for Allura Xper with ClarityIQ). Procedural performance (fluoroscopy time and number of DSA images) of the physicians did not significantly differ between the two cohorts.

  • e) Results based on total dose area product from a single center, prospectively randomized cohort study on 70 consecutive patients (35 for Allura Xper without ClarityIQ and 35 for Allura Xper with ClarityIQ). Number of cine images and contrast medium did not significantly differ between the two cohorts, while fluoroscopy time was significantly higher for the ClarityIQ group. Image quality was based on subjective assessment of two cine runs selected from each patient in two specific projections. Ratings for image contrast, resolution and general appearance were not statistically different. Image noise was more apparent for ClarityIQ images.

  • f) Results based on DSA dose area product per frame from a single center prospective randomized study on 48 patients. DSA runs for Allura Xper with ClarityIQ and Allura Xper without ClarityIQ were randomly acquired on the same patient under same condition of geometry, field of view and injection protocol. Image quality was based on subjective assessment (side-by-side, equal or superior than the other, blinded review by 5 independent radiologists).
