The interest in registering a set of images has quickly risen in the field of medical image analysis. Mutual information (MI) based methods are well-established for pairwise registration but their extension to higher dimensions (multiple images) has encountered practical implementation difficulties. We extend the use of alpha mutual information (alphaMI) as the similarity measure to simultaneou...

OBJECTIVE To assess the role of grayscale and power Doppler sonography in short-term monitoring of acute gouty synovitis. METHODS Clinical and sonographic assessments were performed in a patient with gout. Clinical and sonographic evaluations were performed within the first day of the acute onset of synovitis of the first metatarsophalangeal joint of the left foot and 7 and 14 days after the ...

Research on real-time health systems have received great attention during recent years and the needs of high-quality personal multichannel medical signal compression for personal medical product applications are increasing. The international MPEG-4 audio lossless coding (ALS) standard supports a joint channel-coding scheme for improving compression performance of multichannel signals and it is ...

BACKGROUND Osteoarthrosis is a common cause of low back pain. The diagnosis is clinical and can be confirmed by imaging studies. Pain treatment and confirmation of diagnosis are made by intra-articular injection of corticosteroid and by local anesthetic use, due to clinical improvement. A direct monitoring of the procedure can be done under fluoroscopy, a classic technique, or else by an ultras...

There is a very rich variety of systems of autonomous agents, be it software or robotic agents. In particular, multi-agent systems can include agents that may be part of a team and need to coordinate their actions during their distributed task execution. This coordination requires an agent to observe, i.e., to monitor, the other agents in order to detect a possible coordination failure of the t...

The monitoring of the recovery of femoral muscles, after the knee-joint injury, is possible by the method of ultrasound measurement of the muscular volume. In a clearly defined longitudinal study, our object was to standardize the method of ultrasound measurement of muscular volume and to evaluate its adequacy in practical application in quadriceps muscle rehabilitation. The ultrasound measurem...

Introduction Assessment of disease activity is a fundamental component of the clinical evaluation of children with juvenile idiopathic arthritis (JIA) because persistently active disease plays a major role in causing joint damage and physical functional disability. Furthermore, measurement of the level of disease activity over time is important in monitoring the disease course and in assessing ...

This paper introduces a robust super-resolution algorithm for joint color multi-frame demosaicing. We show that our algorithm, although fast and simple, exhibits convincing results not only within the modeling assumptions, but also for real raw data series. The ultimate goal is its application to telemedical patient monitoring through mobile devices with limited computing power and low quality ...
