London, UK - Philips Healthcare recently supplied an Allura Xper FD10 cardiovascular system to Harefield Hospital. The new equipment complement’s the Hospital’s two existing Philips cath labs and will be used to provide a front-line angiography service, as well as emergency primary coronary interventions.
Chris Prytherch, Superintendent Radiographer says, “Two important features of the Philips system which influenced our selection are the excellent image quality and the unique XperSwing dual-axis rotational angiography functionality. In addition, I have good personal experience of Philips customer service and support and the knowledge that Philips is a leader in cardiovascular imaging also confirmed our choice”.
XperSwing, Philips’ new dual-axis rotational angiography, allows cardiologists to obtain valuable diagnostic information whilst subjecting patients to lower contrast media and X-ray radiation dose in comparison to standard angiography. With this groundbreaking functionality, the rotating C-arm follows a curved trajectory around the patient allowing all desired anatomical views to be imaged in a single run. This results in significant reductions in both X-ray dose and contrast agent loading for the patient and produces high-quality images of the coronary arteries that can be used for diagnosis. The trajectories are preprogrammed and are optimised to provide clinical information while staying within boundaries to avoid collisions. Dedicated trajectories are provided for the left and right coronary arteries.
The Harefield system also comes with Philips’ StentBoost, a simple, quick and efficient tool that enhances stent visualisation in the coronary arteries, showing the stent in relation to the vessel walls during the procedure. This assists in placing the stent more accurately the first time, with the potential to shorten procedures and eliminate the need for additional ones.
The Allura FD10 system provides the optimal balance of efficient workflow, superb imaging and low X-ray dose. It offers a high level of automatic positioning movements, reducing manual tasks. Each user can personalise their settings for automatic positioning and other system movements and control all functionality and interventional tools from the tableside. Its unique DoseWise feature is active at every level, from SpectraBeam and pulsed fluoroscopy to a clear dose display. It gives a range of automatic exposure controls to maximise dose efficiency, including the customisable programmes that automatically select the correct fine-tuned parameters for particular exam types, so that the user gets the right exposure the first time. Grid switched pulsed fluoroscopy maximises the efficiency of the X-ray beam and reduces X-ray dose even more. In addition, Harefield has also invested in Philips’ unique real-time dose meter, DoseAware. The standard thermoluminescent dosimeter, (TLD) reports on accumulated radiation dose. However, Doseware is the only system that provides instant, time-stamped feedback in the examination room so staff can immediately adjust their working habits to minimise radiation exposure. Exposure level can be checked at a glance at a coloured display in the exam room and the site can archive, report and analyse radiation data to maintain high levels of occupational therapy.
Harefield Hospital is well known as one of the largest and most experienced centres in the world for heart and lung transplants. The imaging department has a busy diagnostic and interventional cardiac angiography service, which includes primary angioplasty. This expert treatment is delivered in record time. While the national average is 56 minutes, the hospital has one of the shortest door-to-balloon times in the UK at just 26 minutes, with the help of interventions, completed in less than 20 minutes.
