This study was performed to evaluate the hemodynamic status of children admitted to the intensive care unit, using suprasternal and transesophageal Doppler ultrasound, and to establish a suitable noninvasive technique to monitor trends in cardiac output in critically ill children. Twenty children were ...

The esophageal Doppler cardiac output monitor, described in the early 1970s, provides a safe and minimally invasive means of continuously monitoring the circulation. Initially, suprasternal transthoracic ultrasound or Doppler probes were used for determining cardiac output, but they were not widely ...
Transthoracic M-mode echocardiographic recordings used the Vevo®3100 micro-ultrasound imaging system (FUJIFLIM VisualSonics Inc., Canada) following manufacturer’s instructions. Three measurements taken at end-systole (s) and end-diastole (d) were averaged to calculate corresponding values of ...
Artefacts constitute a paramount issue in medical imaging where the prevalence of artefacts may severely impact the clinical diagnosis accuracy. Specifically, the mistriggering and motion family of artefacts during the cardiac MR image acquisition would eventually damage the visibility of certain tissues, ...
Two-dimensional M-mode echocardiography was performed using a portable Acuson Cypress (Siemens Medical Solutions USA Inc., Mountainview, CA) ultrasound system with a 1.8-3.6 MHz cardiac transducer by a single technician who traveled to field clinics. The left ventricle was first visualised from ...

Accurate cardiac motion estimation from medical images such as ultrasound is important for clinical evaluation. We present a novel regularisation layer for cardiac motion estimation that will be applied after image registration and demonstrate its effect
Spinal Cord Effect of FES-rowing training in people with SCI RS Gibbons et al 825 Cardiac ultrasound assessments and ACE incremental exercise tests as outlined above were completed prior to Phase-1, on completion of Phase-2 and on completion of Phase-3. In addition, on completion of Phase-2...
