A digital Radiography System is Technologically More Advanced than Analogue Systems
Dr Jignesh G Thakker,
Secretary General, Indian Radiological & Imaging Association explains the market of digital and computed radiography
Healthcare infrastructure is developing rapidly across India. The new inventions in the field of radiology are contributing a lot in the way of better diagnostics and imaging.
Ultrasound systems are mostly used in cardiology, radiology and gynaecology departments. But increasingly a number of other departments – critical care, emergency medicine, regional anaesthesia, operating theatres “ have started showing interest in offering ultrasound services for clinical applications. This is because imaging can give immediate answers to specific medical questions. Hospitals are purchasing units for different departments. A digital radiography system is technologically more advanced than analogue and computed radiography systems, which is one of the factors contributing to the growth of this market. The global digital radiography market has been witnessing the trend of film-free radiology departments. However, the increasing adoption of computer radiography systems could pose a challenge to the growth of this market.
In post bypass patients, the physician prefer to conduct examination through soft exposure X-Rays so as to see how wet the lungs are. The cardiac surgeon would like to have an X-Ray with a harder exposure so as to see inserted hard ware, drains, etc. In one exposure with a conventional X-ray it is difficult to achieve both. This results in one of the two being unhappy with the quality. This problem does not occur with digital X-rays as the images can be manipulated to provide a softer and harder image with the same exposure thus keeping both the physician and cardiac surgeon satisfied.
