A new acoustic coupling fluid with ability to reduce ultrasound imaging artefacts in brain tumour surgery - a phase I study
Unsgård, Geirmund; Sagberg, Lisa Millgård; Muller, Sebastien; Selbekk, Tormod (Journal article; Peer reviewed, 2019)Background Anovel acoustic coupling fluid (ACF), with the potential to reduce surgically induced image artefacts during intraoperative ultrasound imaging in brain tumour surgery, has been evaluated with respect to image ... -
Animal study assessing safety of an acoustic coupling fluid that holds the potential to avoid surgically induced artifacts in 3D ultrasound guided operations
Jakola, Asgeir S; Jørgensen, Arve; Selbekk, Tormod; Michler, Ralf-Peter; Solheim, Ole; Torp, Sverre Helge; Sagberg, Lisa Millgård; Aadahl, Petter; Unsgård, Geirmund (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 ... -
Comparison of contrast in brightness mode and strain ultrasonography of glial brain tumours
Selbekk, Tormod; Brekken, Reidar; Indergaard, Marit Kristina; Solheim, Ole; Unsgård, Geirmund (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 ... -
Noninvasive Transorbital Assessment of the Optic Nerve Sheath in Children: Relationship Between Optic Nerve Sheath Diameter, Deformability Index, and Intracranial Pressure
Padayachy, Llewellyn; Brekken, Reidar; Fieggen, Graham; Selbekk, Tormod (Journal article; Peer reviewed, 2018)BACKGROUND: Measurement of optic nerve sheath diameter (ONSD) is a promising technique for noninvasive assessment of intracranial pressure (ICP), but has certain limitations. A recent study showed that the deformability ... -
Registration of MR to Percutaneous Ultrasound of the Spine for Image-Guided Surgery
Bø, Lars Eirik; Palomar, Rafael; Selbekk, Tormod; Reinertsen, Ingerid (Chapter, 2014)One of the main limitations of today’s navigation systems for spine surgery is that they often are not available until after the bone surface has been exposed. Also, they lack the capability of soft tissue imaging, both ... -
Using the CustusX toolkit to create an image guided bronchoscopy application: Fraxinus
Bakeng, Janne Beate Lervik; Hofstad, Erlend Fagertun; Solberg, Ole Vegard; Eiesland, Jon Wostryck; Tangen, Geir Arne; Amundsen, Tore; Langø, Thomas; Reinertsen, Ingerid; Selbekk, Tormod; Leira, Håkon Olav (Journal article; Peer reviewed, 2019)Purpose The aim of this paper is to show how a specialized planning and guidance application called Fraxinus, can be built on top of the CustusX platform (www.custusx.org), which is an open source image-guided intervention ...
