The ability to obtain information about the structure of tissue without taking a sample for pathology has opened the way for new diagnostic techniques. The present paper reviews all currently available techniques capable of producing an optical biopsy, with or without morphological images. Most of these techniques are carried out by physicians who are not(More)
Quantitative aspects of cytology and histology should be considered in diagnostic standardisation processes. The present paper summarises the cytological differences detected in 75 thyroid lesions using a computerized textural analysis. Cells stained with progressive hematoxylin and taken from paraffin blocks were overlaid with the extracted texture. This(More)
BACKGROUND Three-dimensional ultrasound images allow virtual sonography even at a distance. However, the size of final 3-D files limits their transmission through slow networks such as the Internet. OBJECTIVE To analyze compression techniques that transform ultrasound images into small 3-D volumes that can be transmitted through the Internet without loss(More)
Use of collaborative tools is essential in health applications, especially pathology. This paper presents the results of a huge-size image data collaborative system based on SSVS©, suitable for telepathology work, which can be implemented in any system working with large images. Quality, image stitching performance in the JPEG200 wavelet domain and image(More)
A drug e-prescription demonstrator was created in compliance with existing legislation as well as security and privacy standards. A professional ID-card was built on a high security chip (ISTEC E4 High; EAL-5) with a Hash hardware accelerator for a digital signature placed in a single chip USB token. Commercial software products as well as development kits(More)
Health 4.0 applications in the IoE (Internet of Everything) framework generate and use both "Small Data", and "Big Data". While "Big Data" is processed in the Cloud, we advocate for "Small Data" to be processed in the Fog, which is an extension of the Cloud to the edge of the network (close to the IoT devices that stream private health-related information).(More)
Genetic heterogeneity of benign thyroid lesions Static and flow cytometry, karyotyping and in situ hybridization analysis Abstract. The present series includes 75 thyroid lesions (38 goiters, 30 adenomas, 3 follicullo-papillary encapsulated carcinomas and 4 normal thyroid) that were studied by static and flow cytometry. Four cases were also analyzed by in(More)
M edical environments today generate digital images to assist physicians and other health professionals with decision-making tasks. The increasing number of images and usage scenarios, however, necessitates the provision of the proper tools to help medical personnel manage and interpret the images. Computer technology is easing the medical image(More)
