Needle bevel geometry influences the flexural deflection magnitude in ultrasound-enhanced fine-needle biopsy
Saif Bunni, Heikki J. Nieminen
It has been recently demonstrated that use of ultrasound increases the tissue yield in ultrasound-enhanced fine-needle aspiration biopsy (USeFNAB) as compared to conventional fine-…
Multi-modal transducer-waveguide construct coupled to a medical needle
Yohann Le Bourlout, Gösta Ehnholm, Heikki J. Nieminen
Annually, more than 16 billion medical needles are consumed worldwide. However, the functions of the medical needle are still limited to cutting and delivering or drawing material…
An Ultrasonically Actuated Fine-Needle Creates Cavitation in Bovine Liver
Emanuele Perra, Nick Hayward, Kenneth P. H. Pritzker +1
Ultrasonic cavitation is being used in medical applications as a way to influence matter, such as tissue or drug vehicles, on a micro-scale. Oscillating or collapsing cavitation bu…
An Ultrasonically Actuated Needle Promotes the Transport of Nanoparticles and Fluids
Emanuele Perra, Nick Hayward, Kenneth P. H. Pritzker +1
Non-invasive therapeutic ultrasound methods, such as high-intensity focused ultrasound (HIFU), have limited access to tissue targets shadowed by bones or presence of gas. This stud…
Ultrasonic Actuation of a Fine-Needle Improves Biopsy Yield
Emanuele Perra, Eetu Lampsijärvi, Gonçalo Barreto +5
Despite the ubiquitous use over the past 150 years, the functions of the current medical needle are facilitated only by mechanical shear and cutting by the needle tip,i.e.the lance…
Modelling aerosol transport and virus exposure with numerical simulations in relation to SARS-CoV-2 transmission by inhalation indoors
Ville Vuorinen, Mia Aarnio, Mikko Alava +27
We provide research findings on the physics of aerosol dispersion relevant to the hypothesized aerosol transmission of SARS-CoV-2. We utilize physics-based modeling at different le…
Deep-Learning for Tidemark Segmentation in Human Osteochondral Tissues Imaged with Micro-computed Tomography
Aleksei Tiulpin, Mikko Finnilä, Petri Lehenkari +2
Three-dimensional (3D) semi-quantitative grading of pathological features in articular cartilage (AC) offers significant improvements in basic research of osteoarthritis (OA). We h…
