Abstract
Objectives
The purposes of this study were to identify the problems encountered during the operation of a hospital-based intra-oral (IO) image viewing system and to discuss measures for improvements required for its replacement with a more functional and standardized system.
Methods
We implemented a hospital information system consisting of a picture archiving and communication system (PACS) and a radiology information system, and developed our own IO image viewing system, thus achieving a hospital-wide filmless PACS operation. Dentists designated the tooth site to be X-rayed via an order form, and technicians took radiographs of the teeth. The images were then converted to electronic data and dental location information was assigned by DICOM modality worklist management (MWM), followed by transmission to the PACS. Images stored in the PACS were viewed in examination rooms via the image viewing system.
Results
This system enables viewing of images with the same layout used for analog film mounts, as well as the production of a matrix view arranged in a temporal sequence, which is useful when searching for previous images or making comparisons over time. However, problems were encountered in the display format and in the assignment of tooth codes that did not reflect the actual IO condition.
Conclusions
IO images could be displayed through the viewer while maintaining a similar display format to that of film images. However, the image position information should be managed separately for display purposes. Support functions to ensure that information on the actual IO condition is correctly reflected are also required.
