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.


CONCLUSIONS
Workstation schemes for medical imaging information systems should satisfy the basic requirements of medical imaging and investment budget.
