Medical Informatics, an emerging multidisciplinary field at the intersection of medicine, technology, and information sciences, is believed to significantly impact health and medical practice. 1 Nowadays, it is not strange to see new approaches for producing, measuring, and monitoring digital biomarkers using implantable sensors, wearable devices, and mobile health apps on intelligent platforms and knowledgebased systems. Tapping an app icon on a smartphone might save a human life. Mobile health apps can assist patients in managing their medical and health issues, especially in the case of chronic diseases. Mobile apps can also facilitate clinical diagnosis, treatment, and even medical procedures for health professionals. Clinical Informatics, a newly added subspecialty program after medical specialties, seems to improve the current and future of clinical practice. 2, 3 A broader field, known as Health Informatics, is a connected set of disciplines and branches from medicine, computer sciences, and humanities. Similar to medical/clinical Informatics, the overarching field of health Informatics aims to improve access to, enhance quality and safety, and reduce the cost of health services. . .

Introduction & Background: Inclusion of Informatics issues in radiology practice and education is no longer an interest or a research topic. Information technology has affected many aspects of radiology practice much further than technologic advancement of new imaging modalities. The aim of this article is to briefly review the role of computers and IT in mod-earn radiology. Image: Acquisition (CR / DR / DICOM), Storage, Processing (3D reconstruction, Edge enhancement, Contrast change, etc), and Perception of image for computer aided detection are all real example of IT applications affecting diagnostic imaging. Management: Radiology information systems used for multiple purposes (Resource management, Financial management, Report management, Workflow man-agreement) are professional and specialized manage-mint information systems used in imaging depart-mint. Decision Making: Image understanding, Reference databases, Decision support systems may be considered as examples of how IT may improve the decision makings of a radiologist. Education: E-learning in radiology has many advantages to traditional education including reproducibility, use of multimedia technology, distant education, multi-user or even multi-center educations are among them. Digital teaching files can easily replace old film files especially considering the wide avail-ability of originally digital images. Communication: Internet and teleradiology have broken the boundaries of place and time. Consultations, grouped radiology services, overseas practice and countrywide imaging archives are all possible using internet and HTML technology. Wireless tech-neology is growingly included in intra-departmental and intra-hospital radiological image and information transfer shows promising role in emergency radiology. Reporting: Speech recognition, Structured reporting, Multi-media reporting are example of electronic re-porting depicting emerging change in radiology re-ports that were less affected and improved until last decade. 

Medical Informatics is a developing body of knowledge concerned with the use of information and communication technology in support of medical research, education and also for promoting health care delivery. The field focuses on the biomedical information, patient data, and also acquisition, storage, retrieval and optimal use of information for solving problem and decision making. The goal of medical Informatics is to help health care workers improve their way of working and the outcome of their performances. There is a variety of classification types for the different applications of medical Informatics among which Telemedicine, Electronic Medical Records, Information Retrieval and Decision Support Systems are the most important. Different applications of medical Informatics can contribute to better outcomes in patient care and decrease the costs of health care services through error reduction, providing patients with their needed information and supporting physicians with updated information and related knowledge.

Technology in healthcare has grown exponentially in recent years [1]. Today, information and communication technologies have become widespread in healthcare systems worldwide. Since nurses comprise most of the healthcare workforce, they must possess sufficient skills to work in a technology-mediated environment [2]. The advancements in information technology over recent decades have provided significant opportunities for nurses to stay informed about patient conditions [3].

In the last issues we have discussed the future horizons in the aim of providing the best beneficial health services to the patients who ask for innovative treatments.During the last decade, the level of oral health care is increasing by the help of new technologies and epidemiological social long term programs. In the areas that there is no direct access to the sources that equipment and material are resulting from their activities, the most important matter for guiding the society to correct pathway is the increasing the level of education.  

One of the most important problems in the industry is lack of competitiveness, because of transparency is very poor. In the other words, information is not enough for decision making. Then transactions don't have good efficiency. If we have a lot of suitable, on time and relative information, customers buy optimal alternative and on the other hand manufacturers try to keep their market share. This problem, lack of transparency, is a big problem in the Informatics companies. Then a project, entitled ranking of Informatics companies, was defined. In this paper, we searched the literature of ranking in the world, techniques and methodologies of ranking, and models of organization diagnosis. Result of this paper, was designing a model for ranking Informatics companies, rank based on three fields of input, process, and output. Then we generate a quantitative technique for measuring Informatics companies' score. And at last, we ranked Informatics companies.
