Uncertainty evaluation of dead zone of diagnostic ultrasound equipment

This paper presents a model for evaluating measurement uncertainty of a feature used in the assessment of ultrasound images: dead zone. The dead zone was measured by two technicians of the INMETRO’s Laboratory of Ultrasound using a phantom and following the standard IEC/TS 61390. The uncertainty model was proposed based on the Guide to the Expression of Uncertainty in Measurement. For the teste...

Computing Requirements of Modern Medical Diagnostic Ultrasound Machines

Ultrasound is one of the leading medical imaging modalities because it is safe, noninvasive, portable, easy to use, relatively inexpensive and displays images in real-time. Due to its real-time nature, an ultrasound machine must be able to process its incoming data quickly. High computational and throughput requirements in modern ultrasound machines have restricted their internal design to algo...

Medical Equipment Planning

Healthcare providers worldwide are facing an increasingly competitive environment and, in response, are downsizing to reduce costs and improve efficiency. Providers that are unable or unwilling to become more efficient will close. To stay in business, healthcare institutions must consider the cost of medical equipment and plan accordingly. Policies based on sound principles and experience preve...
