The metabolic rate of oxygen consumption, an important indicator of tissue metabolism, can be expressed as the change of net blood oxygen flux into and out of a tissue region per 100 g of tissue. In this work, we propose a photoacoustic and Doppler ultrasound method for imaging local blood oxygen flux of a single vessel. An imaging system for combined photoacoustic and high-frequency ultrasound...

BACKGROUND Estimation of fetal weight is important for antenatal and intrapartum management of pregnant women. Sonographic methods are not readily accessible in under-resourced settings, it is therefore necessary to study the accuracy of a clinical method of estimating fetal weight where this limitation (unavailability of ultrasound) exists. OBJECTIVE To compare the accuracy of clinical and u...

Cardiac ultrasound imaging is used to diagnose various heart diseases. Common analysis pipelines involve manual processing of the video frames by expert clinicians. This suffers from intra- and inter-observer variability. We propose a novel approach using transformer architecture based on Residual Auto-Encoder Network BERT model adapted for token classification. enables videos any length be pro...

Sonographic prediction of macrosomia cannot be improved by combination with pregnancy-specific characteristics Balsyte D, Balsyte D, Schäffer L, Burkhardt T, Wisser J, Kurmanavicius J. Ultrasound Obstet Gynecol 2009; 33: 453–8. We all know how inaccurate fetal weight estimation at ultrasound examination can be. So a search for help in increasing prediction accuracy is reasonable. This study, ho...

We develop a temporal correlation transfer equation (CTE) and a Monte Carlo algorithm (MC) for multiply scattered light modulated by an ultrasonic pulse propagating in an optically scattering medium, where the ultrasound field can be nonuniform and the medium can have spatially heterogeneous distribution of optical parameters. The CTE and MC can be used to obtain the time-varying specific inten...
