Exploratory data analysis of near-infrared spectrum from rats with biodegradable magnesium alloy implant
Mathew, Anna (ACIT;2022, Master thesis, 2022)Biodegradable Magnesium (Mg) based implants were recently developed to replace non-degradable metallic implants. The optical probe can capture variations in vivo from biological tissues using the near-infrared spectrum. ... -
Feasibility study of multi-wavelength optical probe to analyze magnesium implant degradation effects
Hassan, Hafiz Wajahat; Mathew, Anna; Khan, Haroon; Korostynska, Olga; Mirtaheri, Peyman (Proceedings of IEEE Sensors;, Chapter, 2021)Near-infrared spectroscopy (NIRS) is a rapidly developing and promising technology with potential for spectrographic analysis. Understanding NIRS measurements on the implant-tissue interface for hydrogen gas formation as ... -
In Vivo Analysis of a Biodegradable Magnesium Alloy Implant in an Animal Model Using Near-Infrared Spectroscopy
Mathew, Anna; Hassan, Hafiz Wajahat; Korostynska, Olga; Westad, Frank; Mota-Silva, Eduarda; Menichetti, Luca; Mirtaheri, Peyman (Peer reviewed; Journal article, 2023)Biodegradable magnesium-based implants offer mechanical properties similar to natural bone, making them advantageous over nonbiodegradable metallic implants. However, monitoring the interaction between magnesium and tissue ... -
Near-Infrared Spectroscopy for the In Vivo Monitoring of Biodegradable Implants in Rats
Hassan, Hafiz Wajahat; Mota-Silva, Eduardo; Grasso, Valeria; Riehakainen, Leon; Jose, Jithin; Menichetti, Luca; Mirtaheri, Peyman (Sensors;, Peer reviewed; Journal article, 2023)Magnesium (Mg) alloys possess unique properties that make them ideal for use as biodegradable implants in clinical applications. However, reports on the in vivo assessment of these alloys are insufficient. Thus, monitoring ... -
An overview of assessment tools for determination of biological Magnesium implant degradation
Hassan, Hafiz Wajahat; Grasso, Valeria; Korostynska, Olga; Khan, Haroon; Jose, Jithin; Mirtaheri, Peyman (Peer reviewed; Journal article, 2021)Medical implants made of biodegradable materials are advantageous for short-term applications as fracture fixation and mechanical support during bone healing. After completing the healing process, the implant biodegrades ... -
Recent advances in photoacoustic blind source spectral unmixing approaches and the enhanced detection of endogenous tissue chromophores
Grasso, Valeria; Hassan, Hafiz Wajahat; Mirtaheri, Peyman; Willumeit-Römer, Regine; Jose, Jithin (Frontiers in Signal Processing;Volume 2 - 2022, Peer reviewed; Journal article, 2022)Recently, the development of learning-based algorithms has shown a crucial role to extract features of vital importance from multi-spectral photoacoustic imaging. In particular, advances in spectral photoacoustic unmixing ...
