The diagnostic value of ultrasound in pediatric testicular torsion with preserved flow

open access: yesFrontiers in Pediatrics, 2022
BackgroundTesticular torsion is the reduction of blood flow to the testis after spermatic cord torsion. For patients, the diagnosis of testicular torsion is controversial and complicated by the fact that ultrasound blood flow signals are not ...

A mathematical and numerical framework for ultrasonically-induced Lorentz force electrical impedance tomography [PDF]

open access: yes, 2014
We provide a mathematical analysis and a numerical framework for Lorentz force electrical conductivity imaging. Ultrasonic vibration of a tissue in the presence of a static magnetic field induces an electrical current by the Lorentz force.

Ultrasonic colour Doppler imaging [PDF]

open access: yesInterface Focus, 2011
Ultrasonic colour Doppler is an imaging technique that combines anatomical information derived using ultrasonic pulse-echo techniques with velocity information derived using ultrasonic Doppler techniques to generate colour-coded maps of tissue velocity superimposed on grey-scale images of tissue anatomy. The most common use of the technique is to image
