Fully Convolutional Multi-scale Residual DenseNets for Cardiac Segmentation and Automated Cardiac Diagnosis using Ensemble of Classifiers [PDF]
arXiv, 2018 Deep fully convolutional neural network (FCN) based architectures have shown great potential in medical image segmentation. However, such architectures usually have millions of parameters and inadequate number of training samples leading to over-fitting and poor generalization. In this paper, we present a novel highly parameter and memory efficient FCN

Acoustic meta-stethoscope for cardiac auscultation [PDF]
arXiv, 2023 Straight cylindrical stethoscopes serve as an important alternative to conventional stethoscopes whose application in the treatment of infectious diseases might be limited by the use of protective clothing. Yet their miniaturization is challenging due to the low-frequency of bioacoustics signal.

Effect of contrast material injection duration on arterial enhancement at CT in patients with various cardiac indices: Analysis using computer simulation. [PDF]
PLoS ONE, 2018 Arterial peak enhancement on contrast-enhanced CT (CECT) images is thought to be higher in patients with low cardiac function. Using computer simulations, we tested the hypothesis that the relationship between the cardiac index and the aortic peak CT ...

Journal of Applied Clinical Medical Physics, EarlyView.Abstract Purpose Cardiac motion may degrade dose distribution during stereotactic arrhythmia radioablation using the CyberKnife system, a robotic radiosurgery system. This study evaluated the dose distribution changes using a self‐made cardiac dynamic platform that mimics cardiac motion. Methods The cardiac dynamic platform was operated with amplitudes

Dynamic PET cardiac and parametric image reconstruction: a fixed-point proximity gradient approach using patch-based DCT and tensor SVD regularization [PDF]
arXiv, 2019 Our aim was to enhance visual quality and quantitative accuracy of dynamic positron emission tomography (PET)uptake images by improved image reconstruction, using sophisticated sparse penalty models that incorporate both 2D spatial+1D temporal (3DT) information.

Facilitating 1.5T MR‐Linac adoption: Workflow strategies and practical tips
Journal of Applied Clinical Medical Physics, EarlyView.Abstract Background MR‐guided radiotherapy (MRgRT) offers new opportunities but also introduces workflow complexities requiring dedicated optimization. Implementing magnetic resonance linear accelerator (MR‐Linac) technology comes with challenges such as prolonged treatment times and workflow integration issues.

ASSESSING THE RISK OF COMPLICATIONS DURING INDUCTION IN THE PATIENTS WITH LARGE MEDIASTINAL MASS
Вестник анестезиологии и реаниматологии, 2018 Anesthetic management of surgery in patients with large mediastinal mass remains a topical issue of thoracic anesthesiology, since such patients often develop superior mediastinal compression (SMC) which results in a high risk of hemodynamic and ...
