With the help of medical imaging systems physicians have an opportunity to evaluate invisible areas of human body. Medical imaging itself can be divided into two categories: it may be either "clinical" or research-motivated. In this article you will find general overview of imaging technologies and techniques as well as the information on one of the leading European suppliers of medical x ray equipment.
Medical Technology, the application of science to medicine to provide practical solutions to problems normally raised by clinicians with defined medical needs. The products of this technology are engineered and manufactured to facilitate a number of rapidly developing techniques in medicine and to provide safe, reliable performance in clinical practice,including medical imaging systems. While most of the developments have been made and applied in developed countries, medical technology has had far less of an impact in developing countries, as their health-care services are more dependent on locally chosen personnel and less on expensive medical devices. Clinical medical imaging refers to examining diseases and seeking to diagnose in particular human patients. Research-motivated medical imaging has an object to comprehend the processes in animal models and in humans.
Devices to monitor body functions include the air pump sphygmomanometer for measuring blood pressure; the stethoscope, for listening to sounds within heart and lungs; disposable pressure transducers, for the measurement of intervascular pressure; and, from the 1980s on, digital technology for improvements in signal processing, screen displays, and reliability. The stethoscope and the sphygmomanometer, both 19th-century inventions, are still to be found in the doctor's surgery, although there will now also be, in hospitals, an electrocardiograph machine, a portable ultrasound scanner, a computerized tomography scanner,
medical imaging systems, and other high-technology medical test equipment.
Since the discovery of X-rays by Wilhelm Conrad Roentgen, their application has expanded the field of radiology, which has played a significant role in medical diagnostics and, ultimately, in health-care, medical treatment and
increased suppliers of medical x ray
equipment's role. Skin damage as a result of careless use of X-rays led to the early recognition of their harmful effect on human tissue. From this knowledge, and from developments in dose measurement,
in medical imaging systems, specialized therapy systems have been developed alongside methods of administering radiation therapy, including improvements in higher resolution; more sensitive detectors; better tube design; direct digital detectors; and film-less radiology.
Modern medical imaging technology includes the following medical imaging systems and techniques: radiographs, fluoroscopy, computed tomography, magnetic resonance imaging, ultrasound, creation of three-dimensional images, and other imaging techniques. Radiographs, generally known as x-rays, are commonly used to determine the extent and type of a fracture. In combination with radiopaque contrast media, barium for example, these advanced medical imaging systems can be used to display the structure of intestines, which can help to diagnose types of colon cancer.
Fluoroscopy provides images of body's internal structures in real-time. It much resembles radiography, but uses a stable input of x-rays.
Computed tomography, commonly known as a CAT scan, historically yields 2D images of structures in a small body sections. Like radiographs, it uses x-ray radiation, and that is why repeat scans are undesirable to children. Speaking about the suppliers of medical x ray equipment, it is possible to say that there are many of them worldwide. One of the leading European ones is Medical Imaging Systems in Britain, which is a full service medical imaging company. The company offers a great diversity of devices starting from most sophisticated medical imaging systems to disposable accessories.
