![]() Strain and synchrony can be calculated with the use of a variety of analysis packages, some of which are vendor-specific, while others are vendor-independent. In addition, LV strain is correlated with synchrony and their interdependence plays an important role in managing patients with both congenital and acquired heart disease. Left ventricular (LV) strain by two-dimensional (2D) speckle-tracking echocardiography has been shown to be a reliable and clinically important method of quantitatively characterizing cardiac function in children. These data suggest that reliable comparisons between strain values derived from QLAB and TomTec is possible in certain cases, but that caution should be used especially in different hemodynamics conditions. In TomTec, low and high frame rate strain values differed only in a subset of patients (flattened septum). Quantification smoothness settings in QLAB 10.8 resulted in minimal strain differences. Strain values varied widely between QLAB 10.5 and all other software packages, recommending avoidance of QLAB 10.5 for future studies. Synchrony values varied substantially among all packages in children. Quantification smoothness changes in QLAB 10.8 did not impact strain significantly in any patient group temporal resolution changes in TomTec resulted in strain differences in children with flat ventricular septums, but not those with normal or ventricular paced hearts. Synchrony values varied widely for all strain values ( p < 0.001 for both) in all packages. AP4 and SAXM strain values varied significantly between QLAB 10.5 and the other packages. Tracking scores were high for all packages except QLAB 10.5 in the SAXM view. A mixed-effects linear regression model was used, with main effect considered significant if the p-value was < 0.05. AP4 and SAXM strain and synchrony values were recorded. Tracking quality for each package was graded. In TomTec, images were analyzed with both low and high frame rates. In QLAB version 10.8, low, medium, and high quantification smoothness settings were employed. We analyzed the same image acquired from the apical 4-chamber (AP4) and short-axis at the mid-papillary level (SAXM) views in both QLAB (versions 10.5 and 10.8) and TomTec (version 1.2). The study population included 108 children patients were divided into three groups: (1) normal cardiac structure and conduction (2) ventricular paced rhythm and (3) flattened ventricular septum (reflecting right ventricular pressure or volume load lesions). ![]() To test the hypothesis that different packages may affect results, independent of acquisition, we compared values obtained using two commercially available analysis tool (QLAB and TomTec), with several different settings. Foot Print- Metric (HxWxD) 138-154.9 cm x 56.9 cm x 110.Strain and synchrony can be calculated from a variety of software packages, but there is a paucity of data with inter-vendor comparisons in children.Philips HD15 Ultrasound system Specifications: A broad suite of configurable patient reports and exam storage options, such as DVD-CD-R/RW, USB drive, and full DICOM capabilities, provide efficient patient data management and colleague or specialist consulting. ‘Tissue Specific Imaging presets and iSCAN one button image optimisation can quickly provide clear images with little to no adjustment. ‘New Microfine EX focusing provides sharper images and improved tissue uniformity throughout the depth of field through application of new dynamic receive lens tuning with five times more focal points than previous generation systems,’ Philips explained. The Philips HD15 Ultrasound system QLAB quantification software, XRES image processing and PureWave transducer crystal technology. ![]() Features such as contrast enhanced ultrasound and PureWave transducer technology also allow real-time guidance and evaluation of minimally invasive treatments. The system may be used as a primary system for some users, particularly those in emerging markets who require a feature-rich system but may not need all of the features of a high-end ultrasound solution,’ Philips added.Īlong with workflow improvements, the Philips HD15 capabilities include general imaging, cardiac, vascular and obstetrics/gynaecology applications. The Philips HD15 brings capabilities that assure user simplicity and productivity to more clinicians in a variety of clinical settings,’ explained Anne LeGrand, senior vice president, Ultrasound, for Philips Healthcare. Philips HD15 Ultrasound system has added a new platform to its HD ultrasound products the HD15 hich aims to provide small hospitals, clinics and private practices with advanced image clarity and broad application support for everyday use. ![]() ISCAN image optimization is a one-button push that automatically adjusts multiple parameters to quickly achieve a high-quality image quality in 2D, color and Doppler exams.
