Sound speed reconstruction has been investigated for quantitative evaluation of tissue properties in breast examination. Full waveform inversion (FWI), a mainstream method for conventional sound speed reconstruction, is an iterative method that inclu

Red blood cells flow near the axis in a small vessel, known as axial accumulation. This causes a region called the cell-free layer, which does not contain red blood cells near the wall. Then, small particles such as platelets come out to the cell-fre

Accurate morphological information on aortic valve cusps is critical in treatment planning. Image segmentation is necessary to acquire this information, but manual segmentation is tedious and time consuming. In this paper, we propose a fully automati

The dorsal movement of the Achilles tendon during ankle rotation is restricted by anatomical obstructions. Previously, we demonstrated that the anatomical obstruction provides a gain (gainAT) in the proximal displacement of the calcaneus compared to

Abstract The in vitro unconstrained Achilles tendon is nearly straight, while in vivo experiments reveal that the proximal region of the Achilles tendon, adjacent to Kager’s fat pad, bends ventrally during plantarflexion but remains nearly straight

We constructed a coarse-grained (CG) water model based on non-Markovian dissipative particle dynamics (NMDPD) taking into account memory effects. The NMDPD equation of motion was derived from a generalized Langevin equation formulated via the Mori–

The interaction between platelets and vessel walls in the primary aggregation of platelets was investigated using kinetic Monte Carlo simulation for the multiscale simulation of thrombus formation. The kinetic Monte Carlo lattice model of a platelet

Both focus control and hot spot elimination applied to the High Intensity Focused Ultrasound (HIFU) treatment are addressed using three-dimensional numerical simulations, which can faithfully capture the pressure field in the HIFU system involving st

A numerical simulation is conducted for a blood flow in a capillary vessel, including not only red blood cells (RBCs)-like elastic membranes but also platelets-like elastic solids. Recently-developed full Eulerian approaches for coupling with a fluid

Oscillometric noninvasive blood pressure measurement (ONBPM) is nowadays widely applied in health care. However, ONBPM has been found to exhibit large interindividual variability in accuracy. In the present study, we developed a theoretical model to
