Animal study assessing safety of an acoustic coupling fluid that holds the potential to avoid surgically induced artifacts in 3D ultrasound guided operations
(Journal article; Peer reviewed, 2014)Background Use of ultrasound in brain tumor surgery is common. The difference in attenuation between brain and isotonic saline may cause artifacts that degrade the ultrasound images, potentially affecting resection grades ... -
Block-matching-based registration to evaluate ultrasound visibility of percutaneous needles in liver-mimicking phantoms
(Peer reviewed; Journal article, 2021)Purpose: To present a novel methodical approach to compare visibility of percutaneous needles in ultrasound images. Methods: A motor-driven rotation platform was used to gradually change the needle angle while capturing ... -
Comparison of contrast in brightness mode and strain ultrasonography of glial brain tumours
(Journal article; Peer reviewed, 2012)Background Image contrast between normal tissue and brain tumours may sometimes appear to be low in intraoperative ultrasound. Ultrasound imaging of strain is an image modality that has been recently explored for ... -
The Essential Role of Open Data and Software for the Future of Ultrasound-Based Neuronavigation
(Peer reviewed; Journal article, 2020)With the recent developments in machine learning and modern graphics processing units (GPUs), there is a marked shift in the way intra-operative ultrasound (iUS) images can be processed and presented during surgery. Real-time ... -
Simulation and inversion of ultrasonic pitch-catch through-tubing well logging with an array of receivers
(Journal article; Peer reviewed, 2016)Current methods for ultrasonic pitch-catch well logging use two receivers to log the bonded material outside a single casing. For two casings separated by a fluid, we find by simulation that increasing the number of receivers ... -
Sonopermeation Enhances Uptake and Therapeutic Effect of Free and Encapsulated Cabazitaxel
(Peer reviewed; Journal article, 2021)Delivery of drugs and nanomedicines to tumors is often heterogeneous and insufficient and, thus, of limited efficacy. Microbubbles in combination with ultrasound have been found to improve delivery to tumors, enhancing ...
