Positron Emission Tomography (PET) imaging is of importance for diagnosing neurodegenerative diseases like Alzheimer Disease (AD). Computer-aided diagnosis methods could process and analyze quantitatively these images, in order to better characterize and extract meaningful information for medical diagnosis. This paper presents a novel computer-aided diagnosis technique for brain PET images classification...
Today, lossy compression is becoming increasingly important for storage and transmission, of great amounts of numerical data, especially in the telemedicine field. However, the loss of information involved by this kind of compression can be considered as risky in particular for medical applications like diagnosis. To minimize this risk a balance should be done between compression efficiency and experts'...
In this paper we present an interactive tool that can be used to quantify fat infiltration in lumbar muscles, which is useful in studying fat infiltration and lower back pain (LBP) in adults. Currently, a qualitative assessment by visual grading via a 5-point scale is used to study fat infiltration in lumbar muscles from an axial view of lumbar-spine MR Images. However, a quantitative approach (on...
In most recent computer aided celiac disease diagnosis approaches, image regions (patches) showing discriminative features necessarily need to be manually extracted by the medical doctor, prior to the automated classification pipeline. However, although the obtained classification outcomes based on such semi-automated systems are attractive, a human interaction finally is undesired. In this work,...
Positron Emission Tomography imaging (PET) has today become a valuable tool in oncology. The accurate definition of the tumor volume on PET images is a critical step. State-of-the-art methods are based on adaptative thresholding and usually require user interaction. Their performances are hampered by the low contrast, low spatial resolution, and low signal to noise ratios of PET images. In this paper,...
Sleep apnea syndromes are characterized by repeated episodes of breathing pauses (apnea) or significant reductions in respiratory amplitude (hypopnea) during the patient's sleep. These episodes significantly alter the sleep structure of the patient and provoke acute cardiorespiratory responses that may be deleterious in the long term. Continuous positive airway pressure (CPAP) therapy is the gold-standard...
Amnifir project, part of the ANR TECSAN program, intended to assess the capabilities of a new Mid InfraRed spectroscopy (MIR) device. It used a simple fiber optic sampling method: Fiber Evanescent Wave Spectroscopy (FEWS), which makes Point of Care applications possible and delivers a result within a few minutes.To investigate the technology application range, different biological media (tissues,...
Bioimpedance measurements have been used to assess the effects of haemodialysis on patients and to help determine when the desired “dry weight” has been achieved and hence the optimum moment to stop the procedure.In the present research project we seek to develop a localised (on the calf), integrated measurement system capable of transmitting hydration-related impedimetric data, periodically between...
Objectives: In the context of rehabilitation, the use of new technology such as Virtual Reality Technology (VRT) offers multiple possibilities to modulate the functional stimulation of subjects according to needs.Material and methods: In this study, the validity and reliability of our VRT system were investigated in fifteen healthy aged adults (HAA) and seven aged subjects with mild cognitive impairment...
Purpose: Misplacing or losing personal belongings is a concern of everyday life among people of all ages. Older adults with cognitive impairment are significantly more affected by this problem. It is a source of frustration, anxiety, interpersonal conflict and disability in this population. Informal caregivers are greatly impacted by this problem, which compels them to spend a lot of time searching...
Using a personalised medicine perspective, ECOTECH aims at developing new tools and methodologies to characterise and overcome at-risk situations for patients with Parkinson's disease in their daily life activity. With the cooperation of a multidisciplinary research group, patient situations have been studied in real life context in both hospital environment and home and community settings. Gait,...
The electronic health record (EHR) is a very important potential source of data for various areas, such as medical decision support tools, evidence-based medicine or epidemiological surveillance. Much of this data is available in text format. Methods of natural language processing can be used to perform data mining and facilitate interpretation. The purpose of this project was to develop a generic...
The human corneal endothelium is a monolayer of flat hexagonal cells. It is a nearly regular hexagonal tessellation during the first years of life, but with age, becomes less regular in shape and size. The aim is to evaluate geometrically the age of an endothelial mosaic.Segmented endothelial mosaics of healthy subjects of different age groups are compared by morphological criteria. The mosaics are...
Objectives: In eye banks, endothelial cell density (number of endothelial cells per surface unit, ECD) is the main criterion to validate the quality of corneal grafts. Stored corneas present numerous deep endothelial folds. Consequently only few endothelial areas are parallel to the microscope and parallax errors inevitably lead to overestimating ECD.Aim: to present an innovative method of ECs count...
Objectives: Non-contact specular microscopes (SM) have a very small field of observation (usually 0.1 mm2). This constitutes a major limitation when accurate and extended assessment of the corneal endothelium is needed, for instance during clinical trials or difficult diagnosis. Previous contact SM had the advantage of a wide field thanks to the use of an applanating cone but none of the old commercial...
