PureWave
Visualize extraordinary levels of detail
Philips PureWave technology advances the clinical effectiveness of imaging the obese patient
Study results show that PureWave offers additional diagnostic information.
Prof. Karim D. Kalache addresses how to address the technical patient using Philips EPIQ ultrasound system.
Imaging the obese patient Obese patients present special challenges for ultrasound imaging because it is difficult to achieve the penetration required for diagnostic images. As a result, pathology may be missed or the patient may be referred to other imaging modalities for additional studies involving radiation, which can increase the cost of diagnosis. A worldwide challenge Since 1980, the number of overweight and obese adults has increased by 27.5% worldwide, while such rates among children and adolescents have increased by 47.1%. Collectively, the number of overweight and obese people worldwide has increased from 857 million in 1980 to 2.1 billion in 2013. Of these, 671 million are obese.*
EPIQ 7 PureWave transducer family.
The PureWave solution In an effort to address the challenges of imaging this rapidly growing patient population, Philips introduced PureWave transducer technology. Through the use of pure, uniform crystals, which are 85% more efficient than conventional piezoelectric material, PureWave delivers extraordinary levels of detail and contrast resolution and allows for improved penetration at higher frequencies. Today, PureWave transducers offer ultra wide dynamic range and unique beam reconstruction that reinforces exceptional tissue information at greater depths with less noise. So you can image even your largest patients. Plus, with PureWave xMATRIX transducers, you can acquire Live 3D images during diagnostic or interventional procedures, with no change in performance. This technology is integral in our C5-1, C9-2, eL18-4 and X6-1 transducers, allowing for improved penetration in difficult patients while maintaining excellent detail resolution, Doppler sensitivity, and CEUS performance. Available on EPIQ, Affiniti, Sparq, and CX50 ultrasound systems.
* A team of international researchers, led by Prof. Emmanuela Gakidou of the Institute for Health Metrics and Evaluation at the University of Washington, recently published their findings in The Lancet (May 21, 2014). For their study, the team conducted a comprehensive review of surveys, reports and scientific literature looking at overweight and obesity prevalence among adults aged 20 years or older and children ages 2-19 years between 1980 and 2013. Data was drawn from 188 countries over all 21 regions of the world. Overweight was defined as a body mass index (BMI) of 25 kg/m² or higher and obese was defined as a BMI of 30 kg/m² or higher.
