New Encapsulation Concepts for Medical Ultrasound Probes – A Heat Transfer Simulation Study
Do, Nu Bich Duyen; Andreassen, Erik; Edwardsen, Stephen; Lifjeld, Anders; Nguyen, Hoang-Vu; Aasmundtveit, Knut; Imenes, Kristin (Chapter, 2019)Thermal management is important for medical ultrasound probes to maintain optimal performance, reliability, and lifetime of the devices, as well as to avoid heat-induced damage to the patients’ tissue. This paper presents ... -
Novel encapsulation of a medical ultrasound probe
Do, Nu Bich Duyen (Doctoral dissertations at the University of South-Eastern Norway;182, Doctoral thesis, 2024)Ultrasound imaging plays an important role in the diagnosis of cardiovascular diseases. A trans-esophageal echocardiography (TEE) probe uses ultrasound waves to image the heart in real time in three dimensions (3D) from ... -
Salinity Gradient Energy from Expansion and Contraction of Poly (allylamine hydrochloride) Hydrogels
Bui, Tri Quang; Cao, Vinh Duy; Do, Nu Bich Duyen; Christoffersen, Trine Eker; Wang, Wei; Kjøniksen, Anna-Lena (Journal article; Peer reviewed, 2018)Salinity gradients exhibit a great potential for production of renewable energy. Several techniques such as pressure-retarded osmosis and reverse electrodialysis have been employed to extract this energy. Unfortunately, ... -
Thermal Conductivity and Mechanical Properties of Polymer Composites with Hexagonal Boron Nitride—A Comparison of Three Processing Methods: Injection Moulding, Powder Bed Fusion and Casting
Do, Nu Bich Duyen; Imenes, Kristin; Aasmundtveit, Knut Eilif; Nguyen, Hoang-Vu; Andreassen, Erik (Peer reviewed; Journal article, 2023)Materials providing heat dissipation and electrical insulation are required for many electronic and medical devices. Polymer composites with hexagonal boron nitride (hBN) may fulfil such requirements. The focus of this ... -
Thermal management of an interventional medical device with double layer encapsulation
Do, Nu Bich Duyen; Andreassen, Erik; Edwardsen, Stephen; Lifjeld, Anders; Aasmundtveit, Knut; Nguyen, Hoang-Vu; Imenes, Kristin (Peer reviewed; Journal article, 2021)This paper presents a thermal study of a double-layer encapsulation for an interventional medical device, which operates temporarily inside the human esophagus for cardiac imaging. The surface temperature of test samples, ...
