Correcting for motion artifact in handheld laser speckle images.
Laser speckle imaging (LSI) is a wide-field optical technique that enables superficial blood flow quantification. LSI is normally performed in a mounted configuration to decrease the likelihood of motion artifact. However, mounted LSI systems are cumbersome and difficult to transport quickly in a clinical setting for which portability is essential in providing bedside patient care. To address t...
متن کاملMotion Artifact Detection in Confocal Laser Endomicroscopy Images
Confocal Laser Endomicroscopy (CLE), an optical imaging technique allowing non-invasive examination of the mucosa on a (sub)cellular level, has proven to be a valuable diagnostic tool in gastroenterology and shows promising results in various anatomical regions including the oral cavity. Recently, the feasibility of automatic carcinoma detection for CLE images of sufficient quality was shown. H...
متن کاملHandheld, point-of-care laser speckle imaging.
Laser speckle imaging (LSI) enables measurement of relative changes in blood flow in biological tissues. We postulate that a point-of-care form factor will lower barriers to routine clinical use of LSI. Here, we describe a first-generation handheld LSI device based on a tablet computer. The coefficient of variation of speckle contrast was <2% after averaging imaging data collected over an acqui...
متن کاملCorrecting Motion Artifacts in Magnetic Resonance Images
Motion of the patient during magnetic resonance imaging (MRI) introduces artifacts that can severely degrade the images. A method is proposed to correct for artifacts caused by translational motion, using only information contained in the MRI data. Initial simulation results show the algorithm to be effective in the presence of realistic noise levels. The method is suitable for routine clinical...
متن کاملReal-Time Motion Artifact Compensation for PMD-ToF Images
Time-of-Flight (ToF) cameras gained a lot of scientific attention and became a vivid field of research in the last years. A still remaining problem of ToF cameras are motion artifacts in dynamic scenes. This paper presents a new preprocessing method for a fast motion artifact compensation. We introduce a flow like algorithm that supports motion estimation, search field reduction and motion fiel...
