The original image size was \(512\times 512\) pixels. The ventricular cavity in the basal slice was identified by evaluating wall thickening and cavity shrinking in systole.

Manual annotations were performed according to SCMR guidelines with cvi42 software (Circle Cardiovascular Imaging, Calgary, Alberta, Canada) without the use of automated segmentation tools. Ventricular volumes and ejection fraction were then computed from these contours. Endocardial contours were drawn on end-diastolic and end-systolic images. Manual image segmentation was performed by a board-certified pediatric cardiologist sub-specialized in CMR with experience consistent with Society for Cardiovascular Magnetic Resonance (SCMR) Level 3 certification.

Images were obtained with the patients free breathing \(3\) signal averages were obtained to compensate for respiratory motion. Resultsįor congenital CMR dataset, our FCN model yields an average Dice metric of \(91.0\mathrm\), and flip angle of \(60\) degrees.
Dice metric, Jaccard index and Hausdorff distance as well as clinically-relevant volumetric indices are reported to assess and compare our platform with other algorithms including U-Net and cvi42, which is used in clinics. In addition, we trained and validated a deep fully convolutional network (FCN) on a dataset, consisting of \(64\) pediatric subjects with complex CHD, which we made publicly available.
To mitigate this issue, we devised a novel method that uses a generative adversarial network (GAN) to synthetically augment the training dataset via generating synthetic CMR images and their corresponding chamber segmentations. Training artificial intelligence (AI) algorithms for CMR analysis requires large annotated datasets, which are not readily available for pediatric subjects and particularly in CHD patients. Thus, an automated and accurate segmentation platform exclusively dedicated to pediatric CMR images can significantly improve the clinical workflow, as the present work aims to establish. However, although CMR data facilitates reliable analysis of cardiac function and anatomy, clinical workflow mostly relies on manual analysis of CMR images, which is time consuming. Cardiovascular magnetic resonance (CMR) imaging offers non-invasive and non-ionizing assessment of CHD patients.

If that doesn't suit you, our users have ranked 27 alternatives to OsiriX and many of them are available for Windows so hopefully you can.For the growing patient population with congenital heart disease (CHD), improving clinical workflow, accuracy of diagnosis, and efficiency of analyses are considered unmet clinical needs. The most popular Windows alternative is 3D Slicer, which is both free and Open Source. OsiriX is not available for Windows but there are plenty of alternatives that runs on Windows with similar functionality. With ultrafast performance and an intuitive interactive user interface, it is the most widely used medical images viewer in the world.
