In 2013, the researchers on this programme published 42 papers in journals with an IF! In the top 25% of journals according to the IF they have published 22 papers. In 2013 they were cited 1129 times (905 times without autocitations). These figures clearly indicate the above the average results of the group.
F.35 Other
The number of employees in SME Sensum, which was founded by three research programe members F. Pernuš, B. Likar in R. Bernard, and with whom some other researchers of the group collaborate, increased to 48 at the end of 2013, an increase of 7 with respect to 2012. The net sales in 2013 (realised mainly by export) reached 4.300.000 Euros. These figures clearly indicate the capabilities of the researchers to transfer knowledge from academia to industry and the significant socio-economic impact of this transfer!
F.17 Transfer of existing technologies, know-how, methods and procedures into practice
In cooperation with the University of Erlangen (Germany) we developed a new type of a two-step anodization method for fabrication of nanostructured titanium dioxide surfaces composed of vertically oriented nanotubes. The newly developed method enables to control the diameter of the nanotubes and the their length. We also developed a new method to produce titanium dioxide nanopore surfaces. Different titanium dioxide nanostructured surfaces were synthesized in a controlled way by varying the physical conditions, including electrolyte concentration and anodization conditions like time, voltage and temperature. The corresponding anodization set-up for fabrication of the above mentioned nanostructured surfaces was built in our laboratory at the Faculty of Electrical Engineering. The newly developed anodiazation method for controlled fabrication of titanium dioxide nanostructured surfaces will allow us to conduct a number of new experiments with possible applications in the field of biomedical engineering.
F.10 Improvements to an existing technological process or technology
COBISS.SI-ID: 9947476Objective and thorough validation of a 3D-2D registration method requires standardization of the validation methodology, which includes design of validation image data sets, definition of corresponding “ground truth” and its accuracy, and design of validation protocol and metrics. Currently no standardized validation methodology exists for validating 3D-2D registration algorithms to be used in endovascular interventions. In 2013 we have, therefore, developed such a standardized registration validation methodology for brain vasculature. The methodology is described in this journal paper and at: http://lit.fe.uni-lj.si/tools.php?lang=eng#Gold standard for 3D-2D registration of cerebral angiograms
F.31 Development of standards
COBISS.SI-ID: 9795156The accuracy of the radiometric response of acousto-optic tunable filter (AOTF) hyperspectral imaging systems is crucial for obtaining reliable measurements. It is therefore important to know the adiometric response and noise characteristics of the hyperspectral imaging system used. A radiometric model of an AOTF hyperspectral imaging system composed of an imaging sensor radiometric model (CCD, CMOS, and sCMOS) and an AOTF light transmission model is proposed. Using the radiometric model, a method for obtaining the fixed pattern noise (FPN) of the imaging system by displacing and imaging an illuminated reference target is developed. Methods for estimating the temporal noise of the imaging system, using the photon transfer method, and for correcting FPN are also presented. Noise estimation and image restoration methods were tested on an AOTF hyperspectral imaging system. The results indicate that the developed methods can accurately calculate temporal and FPN, and can effectively correct the acquired images. After correction, the signal-to-noise ratio of the acquired images was shown to increase by 26%.
