Brain activity has multiple attributes, including electrical, metabolic, hemodynamic, and hormonal. Modern methods for studying brain functions such as PET (Positron Emission Tomography), fMRI (Functional Magnetic Resonance Imaging), and MEG (Magnetoencephalogram) are widely used by scientists. However, the EEG is a tool used for research and diagn...
For neuroscientists, it is a challenge to keep track of the data and metadata generated in each investigation and accurately extract all the relevant information, a crucial fact to interpret results and a minimum requirement for researchers to build their investigations on previous findings. Keep as much information as possible from the start, even...
Neuroscience is a field of science that studies the nervous system from neural functioning to behavior and how its different elements interact. The Cuban Neuroscience Centre is the main neuroscience research institution in the country, where different problems associated with the launch and management of neuroscience dataset processing queues has b...
Various projects have been carried out in developed countries for the organization of Neuroscience databases, including data repositories. The Cuban Neuroscience Center is the leading institution for neuroscientific studies in the country. Due to the volumes of data that are managed in its repository, statistical management and obtaining reports ar...
Introducción:
la especialidad de neurofisiología se ocupa del estudio, la evaluación del sistema nervioso (central y periférico), su modificación funcional, de los órganos sensoriales y musculares, tanto en condiciones normales como patológicas. La normalización de la información sobre esta especialidad es compleja, porque cada institución hospital...
Applications and computer services implementation in the health sector is one of the information and communications technologies challenges. Medical informatics as an integrating discipline receives an important impact from the science, technology and society approach that dominates the biomedical field, biotechnological and pharmaceutical sciences...
Sanitary services present various challenges, one of them are bottlenecks. bottlenecks cause anomalies and eventualities in the processes flow, directly affecting the patient’s attention quality. The health organizations procure to apply a process management focusing and the usage of different technologies to improve their performance. Process mini...
The hospital information systems collect an important volume of data, however, they lack mechanisms to analyze the execution of the processes and identify variability. In practically every step of the care process and at various levels of grouping: population and individual the variability is present. From a population point of view, performance ra...
Process mining aims to discovering, monitoring and improving process, starting from events logged during process execution on information systems. Nevertheless, available process mining techniques for process diagnosis offer insufficient information about event log completeness or infrequent process behavior, affecting process comprehension. A new...
Process mining includes different perspectives, among which is the temporal perspective, which proves to be effective and useful in critical sectors such as health. It allows determining the time differences in a healthcare processes, to identify bottlenecks and eventualities that slow down the operation of processes in hospitals. The objective of...
Process mining is responsible for generating knowledge and discovering processes based on the extracted records of events found in information systems, for diagnosing, evaluating and improving their performance and behavior. This paper focuses on carrying out a review of the published research on this alternative for the analysis of business proces...
The National Health System (SNS for its acronym in Spanish) in Cuba is currently engaged in a process of transformations aimed at reorganizing, compacting and regionalizing health services. One of the most interesting transformations is the computerization of health processes. This is due to the need to achieve a single record of the clinical infor...
Health information systems have a large amount of data, but they lack of mechanisms to analyze the execution of their processes. Process mining techniques analyze the real data of computer systems and are useful for the detection of variability in the execution of business processes. The present research is oriented to the development of a model fo...
Process mining includes different perspectives, among which is the time perspective, which turns out to be effective and useful in critical sectors such as health. It allows to determine temporary differences in health care processes, identify bottlenecks and eventualities that slow down the functioning of processes in hospitals. The objective of t...
Process Mining is a novel alternative to analyze the real processes, from extraction of knowledge of the event logs available in the information systems. The discovery is one type of process mining that allows obtaining process models, which can be observed visually eventualities in the processes modeled. Inductive Visual Miner is a plugin of ProM...
Process mining allows for discovery, monitoring, and improving processes identified in information systems from their event logs. In hospital environments, process analysis has been a crucial factor for cost reduction, control and proper use of resources, better patient care, and achieving service excellence. This paper presents a new component for...
The institutions of the health sector, have been adapted to systems and information technologies that have emerged, allowing them to grow and above all, provide better and more varied services. To make proper medical decision involves a complex, serious, responsible act, it must be assumed the most comprehensive preparation, without improvisations,...

Most companies use information systems to manage the execution of the business processes. Information systems record in a trace the actions that are performed when running instances or cases of business process. Obtaining the process models from the information contained in the trace is possible by means of use of process mining which its offers mu...
Decision making requires a high performance in strategic processes. The process mining is responsible for generating knowledge and discover processes from event logs that are extracted from information systems, for finding errors, inconsistencies and vulnerabilities. To improve its performance, organizations are looking for a better process managem...
La Minería de procesos permite descubrir, monitorear y mejorar los procesos identificados en los sistemas
de información que poseen las organizaciones a partir de sus registros de eventos. Su aplicación
en otras esferas demuestra que en sistemas hospitalarios permite monitorizar la utilización de los recursos,
como los implementos quirúrgicos, perm...
La Minería de Procesos es de vital importancia para los Sistemas de Información debido a que permite
un análisis objetivo de los procesos basado en la ejecución de las actividades de la organización. La
aplicación de minería de procesos se presenta como una tecnología de importancia para su puesta en
práctica en los Sistemas de Información Hospital...
Currently most organizations use information systems to manage and optimize their processes, these systems store event information associated with the activities of the business processes, called event log. The discovery of models from the information contained in such record is what is called Mining Process. For the discovery of processes have bee...
The majority of modern information systems mechanisms used to record the actual execution of the processes, possess a trace record, which is the starting point of mining processes. Process mining techniques, allow to extract non trivial and useful information from the trace records stored by information systems for further analysis. One of the tech...
Worldwide the health sector institutions use hospital information systems to manage the execution of your processes. These systems recorded in the form of traces the actions when you run instances or cases of business processes. Traces of execution to pass through a process of transformation are converted in event logs. The starting point for imple...

I need MRI and PET image datasets of the same patient for test.
Dear colleagues
Where can I find free dataset on brain PET and MRI images to test some fusion algorithms? Note that both types of images must correspond to the same people. Thank you and looking forward to your collaboration.
