Workstation scheme and implementation for a medical imaging information system.
OBJECTIVE: To discuss the scheme and implementation of workstation configuration for medical imaging information systems suitable to the practical situation in China. METHODS: The workstations were logically divided into picture archiving and communication system (PACS) workstations and radiology information system (RIS) workstations. The former applied to three kinds of diagnostic practice: the small matrix images, large matrix images and high resolution grayscale display applications. The latter consisted many different models defined by the usage and function processes. RESULTS: A dual-screen configuration for image interpretation workstations integrated the image-viewing and reporting procedures physically. Small matrix images as CT or MR were operated on 17 inch (1 inch = 2.54 cm) color monitors, while conventional X-ray interpretation was performed on 21 inch color monitors or portrait format grayscale 2 k by 2.5 k monitors. All other RIS workstations not involved in imaging process were set up with a common PC configuration. CONCLUSION: Workstation schemes for medical imaging information systems should satisfy the basic requirements of medical imaging and investment budget.
