Diagnostic accuracy of chest X-rays acquired using a digital camera for low-cost teleradiology
Store-and-forward telemedicine, using e-mail to send clinical data and digital images, offers a low-cost alternative for physicians in developing countries to obtain second opinions from specialists. To explore the potential usefulness of this technique, 91 chest X-ray images were photographed using a digital camera and a view box. Four independent readers (three radiologists and one pulmonolog...
متن کاملEvaluation of the Diagnostic Accuracy of Chest X-rays Acquired Using a Digital Camera for Low-cost Teleradiology
Background Fourteen African countries have no radiologists, and in others few radiologists work in rural areas. Teleradiology provides advice to doctors in remote settings but cost and poor internet connections limit its use. This study builds on several previous studies evaluating scanners and digital cameras for low-cost teleradiology. Digital camera images can be attached to emails and sent ...
متن کاملA Proposed Simple Teleradiology System Using a Digital Camera
Background & Aims: Teleradiology as an efficient way for avoiding unnecessary transfer of patients to special medical centers requires the images with digital format. However, in some developing countries, including Iran, imaging is being done using non digital devices. In such cases, changing analog images into digital ones can solve the problem. The method which is nowadays used for digita...
متن کاملLow-cost digital subtraction angiography.
Intravenous angiography was an important diagnostic tool earlier in th is century [1] , however, the technique had many drawbacks . Film timing was critical, the volume of contrast material was high , and the contrast resolution was often poor. When safer techniques for direct arteriography were developed, intravenous angiography was abandoned . Computed digital image processing has brought a r...
متن کاملLow Cost Digital Vibration Meter
This report describes the development of a low cost, digital Micro Electro Mechanical System (MEMS) vibration meter that reports an approximation to the RMS acceleration of the vibration to which the vibration meter is subjected. The major mechanical element of this vibration meter is a cantilever beam, which is on the order of 500 µm in length, with a piezoresistor deposited at its base. Vibra...
