Cardiac Cavity Segmentation in Echocardiography Using Triangle Equation [PDF]

, 2009
In this paper, cardiac cavity segmentation in echocardiography is proposed. The method uses triangle equation algorithms to detect and reconstruct the border. Prior to the application of both algorithms, some preprocessings have to be carried out.

Regularized Single‐Cell Imaging Enables Generalizable AI Models for Stain‐Free Cell Viability Screening

Small Methods, EarlyView.
Recent advances in AI suggest the potential for stain‐free cell viability screening on brightfield microscopy images. However, no model has been reliably generalized across previously unseen cell types and compounds. Here, we show that “regularized imaging” of single cells in nanowells enables training of generalizable AI models for stain‐free ...

Alteration of Phase Transformation Behavior and Prior Austenite Grain Structure Due to Elevated Tramp Element Concentrations in a Hypoeutectoid Steel

steel research international, EarlyView.
The phase transformation behavior of a hypoeutectoid steel is studied in comparison with alloys containing higher concentrations of tramp elements, simulating high recycling rates. The examination of microstructures reveals that the tramp elements facilitate the formation of displacive phases along with retained austenite.
