Ultrasound picture archiving and communication systems.

In this chapter, we discussed the concept of PACS infrastructure and the methods of implementing an ultrasound PACS. An ultrasound PACS differs from other radiologic PACS modules in several aspects. First, ultrasound image acquisition requires the interaction from the operator to initiate the image capture process. Second, ultrasound display requires pseudocolor to show flow images. Third, ultrasound examinations include dynamic studies that generate many images in real-time. The last feature is difficult to achieve even with current technology. One method is to explore video transmission, storage, and display technology. We have researched and implemented a fiber optic broadband video system for transmitting, archiving, and displaying CT and MR images in real-time. This system connects three CT and three MR scanners in three buildings including the CHS and the MP over a distance of about 2.5 km. We believe this technology can be extended for real-time video ultrasound image transmission, archiving, and display.
