The wave velocity © at each frequency is calculated by finding the... Read More
2012-153 – The practice of radiology is a non-linear process where image processing and routing decisions for best practice are often done by humans on the fly. Commercial PACS and image processing workstations assume a fixed workflow that is enshrined in their database schemas, and may only account for 4-5 stages in the lifetime of a diagnostic imaging study. DEWEY uses DICOM (with proposed expansion... Read More

The effect... Read More
