Published in 2018 at "Computers in biology and medicine"

DOI: 10.1016/j.compbiomed.2018.05.029

Abstract: Optical mapping is widely used as a tool to investigate cardiac electrophysiology in ex vivo preparations. Digital filtering of fluorescence-optical data is an important requirement for robust subsequent data analysis and still a challenge when… read more here.

Published in 2023 at "Journal of Instrumentation"

DOI: 10.1088/1748-0221/18/04/p04002

Abstract: The radiation detector output is often shaped into Gaussian or quasi-Gaussian shape to improve the measurement performance. An adaptive digital Step-Gaussian filter is presented for quasi-Gaussian pulse shaping in this paper. It can be applied… read more here.

Published in 2023 at "Nuclear medicine communications"

DOI: 10.1097/mnm.0000000000001710

Abstract: OBJECTIVE The objective was to evaluate the impacts of different reconstruction methods [filtered back projection (FBP) and ordered subset expectation maximization (OSEM)] and different filters (Butterworth filter and Gaussian filter) on the image quality in… read more here.
