compared to a system without ClarityIQ while maintaining image quality. In this clinical area, 3 studies were performed with 1,872 patients worldwide.
Significantly lower radiation dose for patients at equivalent image quality. ClarityIQ is clinically proven to deliver significantly lower dose - based on 37 peer-reviewed clinical studies with over 19,000 patients. Depending on the clinical area, dose reductions between 65-67% have been achieved.[a-d, *]
This study identifies differences between image-guided therapy systems from different vendors. Philips interventional fluoroscopy system shows lower radiation use and higher subjective perception of image quality in multi-vendor study.*
Philips Azurion 7 with FlexArm provides unlimited imaging flexibility for diverse procedures and exceptional positioning freedom for medical teams. Its compact set-up provides a highly cost-effective environment. ClarityIQ technology, part of the Azurion system, enables excellent visibility at low X-ray dose levels for patients of all sizes.
“The assumption was that if we reduce dose, we’re compromising image quality. And nowadays with ClarityIQ, we don’t have to worry about these two issues.”

a) Investigator initiated, interventional radiology study at Thomas Jefferson University Hospital, Philadelphia, PA, USA, equipped with Philips image guided therapy system with ClarityIQ technology and comparable Siemens Artis Q image guided therapy systems. Phantom study investigated differences in system-reported radiation dose estimates, cumulative air kerma (CAK) and kerma area product (KAP), for 4,381 clinical procedures. In clinical study, two blinded interventional radiologists reviewed image quality for Philips and Siemens systems with same patients, same procedures and same physicians. Subset analysis with 40 patients undergoing repeat embolization of the same lobe of the liver, performed by the same physician.
b) In 37 individual comparative studies, Philips ClarityIQ was associated with reductions in patient radiation exposure.1-37
c) Relationship between radiation exposure and risk of complications, long-term health risk, procedure time and patient characteristics, procedure complexity, as reported in medical guidelines.38
d) 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.
*Investigator initiated, partially funded by Philips interventional radiology study at Thomas Jefferson University Hospital, Philadelphia, PA, USA, equipped with Philips interventional fluoroscopy system with ClarityIQ technology and comparable Siemens Artis Q interventional fluoroscopy systems. Phantom study investigated differences in system-reported dose estimates. Retrospective clinical case analysis compared cumulative air kerma (CAK), kerma area product (KAP) and procedure time for 4,381 procedures. Subset analysis on 40 patient cohort, wherein the same procedure was performed by the same physician on Philips and Siemens systems, compared CAK and KAP along with a blinded assessment of subjective image quality.This study was performed on an AlluraClarity system. The ClarityIQ technology is implemented exactly the same on Allura and Azurion systems.
