Learning Ultrasound Scanning Skills from Human Demonstrations [PDF]

, 2021
Recently, the robotic ultrasound system has become an emerging topic owing to the widespread use of medical ultrasound. However, it is still a challenging task to model and to transfer the ultrasound skill from an ultrasound physician. In this paper, we propose a learning-based framework to acquire ultrasound scanning skills from human demonstrations ...

Computational Models of Material Interfaces for the Study of Extracorporeal Shock Wave Therapy [PDF]

Commun. Appl. Math. Comput. Sci. 8 (2013) 159-194, 2012
Extracorporeal Shock Wave Therapy (ESWT) is a noninvasive treatment for a variety of musculoskeletal ailments. A shock wave is generated in water and then focused using an acoustic lens or reflector so the energy of the wave is concentrated in a small treatment region where mechanical stimulation enhances healing.

On the Norms of Circulant and $r-$Circulant Matrices With the Hyperharmonic Fibonacci Numbers [PDF]

Journal of Inequalities and Applications, (2015) 2015:253, 2015
In this paper, we study norms of circulant and $r-$circulant matrices involving harmonic Fibonacci and hyperharmonic Fibonacci numbers. We obtain inequalities by using matrix norms.

Models for plasma kinetics during simultaneous therapeutic plasma exchange and extracorporeal membrane oxygenation [PDF]

arXiv, 2020
This paper focuses on the derivation and simulation of mathematical models describing new plasma fraction in blood for patients undergoing simultaneous extracorporeal membrane oxygenation and therapeutic plasma exchange. Models for plasma exchange with either veno-arterial or veno-venous extracorporeal membrane oxygenation are considered.

Some identities for enumerators of circulant graphs [PDF]

J. of Algebr. Combin., v.18:3 (2003), 189-209 (in a revised form), 2001
We establish analytically several new identities connecting enumerators of different types of circulant graphs of prime, twice prime and prime-squared orders. In particular, it is shown that the semi-sum of the number of undirected circulants and the number of undirected self-complementary circulants of prime order is equal to the number of directed ...

Converting Hemodialysis (HD) membranes to Extracorporeal Membrane Oxygenation (ECMO) machines [PDF]

arXiv, 2020
Crises like COVID-19 can create a massive unmet demand for rare blood oxygenation membrane machines for impaired lungs: Extracorporeal Membrane Oxygenation (ECMO) machines. Meanwhile, Hemodialysis (HD) machines, which use membranes to supplement failing kidneys, are extremely common and widespread, with orders of magnitude more available than for ECMO ...

A Preliminary Approach for Learning Relational Policies for the Management of Critically Ill Children [PDF]

arXiv, 2020
The increased use of electronic health records has made possible the automated extraction of medical policies from patient records to aid in the development of clinical decision support systems. We adapted a boosted Statistical Relational Learning (SRL) framework to learn probabilistic rules from clinical hospital records for the management of ...

Fluctuations of eigenvalues of patterned random matrices [PDF]

Journal of Mathematical Physics 58, 063301 (2017), 2016
In this article we study the fluctuation of linear statistics of eigenvalues of circulant, symmetric circulant, reverse circulant and Hankel matrices. We show that the linear spectral statistics of these matrices converges to the Gaussian distribution in total variation norm when the matrices are constructed using i.i.d. normal random variables.

In Vivo Quantification of Clot Formation in Extracorporeal Circuits [PDF]

Studies in Health Technology and Informatics, Vol. 184, pp. 148--150, January 2013, 2012
Clot formation is a common complication in extracorporeal circuits. In this paper we describe a novel method for clot formation analysis using image processing. We assembled a closed extracorporeal circuit and circulated blood at varying speeds. Blood filters were placed in downstream of the flow, and clotting agents were added to the circuit.

Robotic-assisted Ultrasound for Fetal Imaging: Evolution from Single-arm to Dual-arm System [PDF]

arXiv, 2019
The development of robotic-assisted extracorporeal ultrasound systems has a long history and a number of projects have been proposed since the 1990s focusing on different technical aspects. These aim to resolve the deficiencies of on-site manual manipulation of hand-held ultrasound probes. This paper presents the recent ongoing developments of a series
