The purpose of this study was to establish standard reference values of the Transversus abdominis and internal oblique muscles during maximal inhalation, exhalation and respiratory pause in a standing position. Additionally, this study aims to estimate the correlation between those standard reference …

Described here is an ultrasound technique used to study tongue movements, particularly lateral tongue movements, during mastication. A method to analyze spatial and temporal tongue movements was developed, and the feasibility of using this method was evaluated. Biplane ultrasound images of tongue movements …

Inleiding: Jaarlijks komen 15 op de 1000 mensen met schouderklachten bij de huisarts, waarvan 70% het de pezen van de rotator cuff betreft. Voor de diagnose wordt gebruik gemaakt van Musculoskeletal Ultrasound (MSU) en om de diagnose te optimaliseren zijn referentiewaarden nodig. Het doel van het onderzoek …

Poor mastication has been widely associated with cognitive impairments in elderly people. Ultrasound technology (US) and bite force measuring devices are both used to assess the masticatory muscles, providing an indication of their condition. Objective: The purpose of this study was to assess masseter …

Patients scheduled for a magnetic resonance imaging (MRI) scan sometimes require screening for ferromagnetic Intra Orbital Foreign Bodies (IOFBs). To assess this, they are required to fill out a screening protocol questionnaire before their scan. If it is established that a patient is at high risk, radiographic …

This work provides a feasibility study on estimating the 3-D locations of several thousand miniaturized free-floating sensor platforms. The localization is performed on basis of sparse ultrasound range measurements between sensor platforms and without the use of beacons. We show that this task can be …

Fish have the natural behaviour to move across various aquatic ecosystems and for some species this is of vital importance. Migration is often a seasonal phenomenon which occurs in order to move between habitats, such as winter refuges-, foraging- and spawning or nursery habitats, also escaping unfavourable …

Achtergrond Lage rugpijn komt veel voor onder de Nederlandse bevolking. Er wordt een stijging verwacht van 7% tussen 2005 en 2025. In 85% is er geen sprake van een specifieke lichamelijke oorzaak en is er sprake van aspecifieke lage rugpijn. Het disfunctioneren van het actieve subsysteem leidt tot meer …

Ultrasonic Verification is a new method for the monitoring large surface areas of CFRP by ultrasound with few sensors. The echo response of a transmitted pulse through the structure is compared with the response of an earlier obtained reference signal to calculate a fidelity parameter.
