Information technology, in the modern times has spread its wings so wide into almost all aspects of human life that, it has evolved into the major provider of communication and research assistance in most fields of progressive education and investigation. In the essential science of Medicine and Health care, technological advances are mainly promoted with the inevitable backing and application of the ever progressing field of computers and communication technology.Radiology departments and other medical disciplines use telemedicine, which is an efficient application of both telecommunications and Information technology to conduct distance health care and to provide health care access to isolated communities in far away rural areas. This form of communication is also inevitable in emergency health care and ambulance services. Tele medicine services include the various fields of medicine, including telenursing, telepharmacy, teletrauma, telepsychiatry and Telecardiology services among other fields.Telecardiology services are mainly employed in Radiology services for the effective transmission of radiographic images to hospitals and cardio clinics from emergency care departments and ambulances. This procedure is effectively executed by setting up a connection and communication network from an image dispatching, and transmitting station to an image reception and reviewing station. This is accomplished by an expert communication networking link via the internet, between two computers. Advancements in the field of telemedicine nowadays enable the tele reviewers to watch clinical procedures that are being carried out in distant places, and to study and analyze image results and give advice upon appropriate treatment methods. This can be achieved without the use of any special software, and with the use of just a personal computer and a Digital supplier line.Tele imaging services and health care businesses team up with doctors, health clinics and labs to provide competent medical solutions in the major departments like cardiology, radiology, and all other fields that use imaging as a part of medical analysis. They employ highly trained professionals to work with the medical care givers and technicians, in order to smoothly carry out the operations involved and to keep tabs and provide assistance. They keep close working relationships with the various medical units and extend their services in promoting medical education and research by providing samples and data. The developments and enhancement of technologies connected with telemedicine and data processing have helped immensely in the quality of healthcare that is now available worldwide. They have also helped in reducing the costs in research and treatment, by reducing paperwork, and travel expenses and by expanding accessibility. It has also improved the chances for prompt tracking and better management of epidemics and serious and persistent illnesses.Health information technology plays a major role in the overall management of medical departments, and also provides effective links between patients, doctors and other health care providers, government agencies and even health insurance agencies.
