INTEGRATION OF ULTRASOUND IN A FULLY DIGITAL RADIOLOGY DEPARTMENT

OBJECTIVES. The authors' experiences concerning the use of video-frame grabbers for the integration of ultrasound devices into a fully digita l imaging environment are presented. METHODS. Video acquisition workst ations (VAW) (Siemens, Gammasonics Inc., Hoffman Estates, IL) are used in our department to link ultrasound devices to the picture archiving and communication system (PACS). A study was carried out concerning t he impact of this integration on throughput by comparing the average t imes for image acquisition and storage in this digital system with the times found in a conventional archive, which is still used for some u ltrasound units. The annual costs for the two kinds of archives were c ompared. RESULTS AND CONCLUSION. Video acquisition is a feasible way o f integrating ultrasound in a digital environment. No impact on throug hput has been found for the radiologist carrying out the examination, but for the assisting technologist, the times for image retrieval and archiving could be reduced from 3 minutes and 8 seconds to 24 seconds per patient. The instant availability of previous studies could be inc reased from 93.5% to almost 100%. Archive costs could he reduced by 28 %, with further reductions to be expected using different archive conf igurations.
