A Spectral Filter Array Camera for Clinical Monitoring and Diagnosis: Proof of Concept for Skin Oxygenation Imaging
Bauer, Jacob Renzo; Bruins, Arnoud A.; Hardeberg, Jon Yngve; Verdaasdonk, Rudolf (Journal article; Peer reviewed, 2019)The emerging technology of spectral filter array (SFA) cameras has great potential forclinical applications, due to its unique capability for real time spectral imaging, at a reasonable cost.This makes such cameras ... -
An Evaluation Framework for Spectral Filter Array Cameras to Optimize Skin Diagnosis
Bauer, Jacob Renzo; Thomas, Jean-Baptiste; Hardeberg, Jon Yngve; Verdaasdonk, Rudolf M. (Journal article; Peer reviewed, 2019)Comparing and selecting an adequate spectral filter array (SFA) camera is application-specific and usually requires extensive prior measurements. An evaluation framework for SFA cameras is proposed and three cameras are ... -
Optical skin assessment based on spectral reflectance estimation and Monte Carlo simulation
Bauer, Jacob Renzo; Hardeberg, Jon Yngve; Verdaasdonk, Rudolf (Journal article; Peer reviewed, 2017)Optical non-contact measurements in general, and chromophore concentration estimation in particular, have been identified to be useful tools for skin assessment. Spectral estimation using a low cost hand held device has ... -
Skin color simulation - review and analysis of available Monte Carlo-based photon transport simulation models
Bauer, Jacob Renzo; Pedersen, Marius; Hardeberg, Jon Yngve; Verdaasdonk, Rudolf (Chapter, 2017)Optical assessment is a useful tool for non-invasive skin assessment avoiding scarring, time delayed diagnosis, hurting, and inconvenience for patient and practitioner. This has led to wide adaption of digital imaging and ... -
Spectral filter array cameras as a diagnostic skin imaging tool
Bauer, Jacob Renzo (Doctoral theses at NTNU;2020:55, Doctoral thesis, 2020)Skin is the human’s largest organ and has many vital functions including protection from pathogens, temperature regulation, touch sensation, vitamin D synthesis and protecting the water inside the body. It does not only ... -
Towards real-time non contact spatial resolved oxygenation monitoring using a multi spectral filter array camera in various light conditions
Bauer, Jacob Renzo; van Beekum, Karlijn; Klaessens, John; Noordmans, Herke Jan; Boer, Christa; Hardeberg, Jon Yngve; Verdaasdonk, Rudolf (Journal article; Peer reviewed, 2018)Non contact spatial resolved oxygenation measurements remain an open challenge in the biomedical field and non contact patient monitoring. Although point measurements are the clinical standard till this day, regional ... -
The vascular occlusion test using multispectral imaging: a validation study
Bruins, Arnoud A.; Geboers, Diederik G. P. J.; Bauer, Jacob Renzo; Klaessens, John; Verdaasdonk, R.M.; Boer, Christa (Peer reviewed; Journal article, 2020)Multispectral imaging (MSI) is a new, non-invasive method to continuously measure oxygenation and microcirculatory perfusion, but has limitedly been validated in healthy volunteers. The present study aimed to validate the ...
