•
Provide software interfaces between PACSLink and the LOCAL PANEL and SERVICE LAPTOP to
allow the DRE to communicate with the LOCAL PANEL and the SERVICE LAPTOP and to deliver
jobs from an SCU to the MIM Delivery Interface for rendering.
•
Handle setup and configuration of the SCUs identified in the Connection Database.
•
Support controlled startup and shutdown of the DRE.
•
Accept or reject print requests from DICOM, depending on the usability of SCU-specified parameters
for the print job.
•
Accept and queue valid print jobs from an SCU for transmission to the MIM Delivery Interface
component of the PACSLink software, and maintain maximum throughput of the jobs to achieve
printing of 1xx sheets per hour, for 35 by 43 cm FILM.
•
Support requests from the LOCAL PANEL or SERVICE TOOL to generate test prints, take the spooler
off--line and then on--line, do queue management, retrieve jobs, delete jobs, reprint jobs, and display
status and error conditions.
•
Handle error reporting and job recovery, and support N--EVENT reporting to the SCU.
When the PACSLink receives images from an SCU, it writes them into the image cache partition of the
HARD DISK as Microsoft WINDOWS files. PACSLink retains the job information and connections to the
images, but not the images themselves. The available space in the image cache partition is monitored by
PACSLink with reference to 2 configurable set points, a “high water mark” and a “low water mark”. If the
cache is filled to the high water mark, successfully delivered jobs/images are deleted, oldest first, until
either the low water mark is reached in disk space or there are no more delivered jobs/images available to
delete. If sufficient disk space cannot be made available, no jobs will be accepted from an SCU.
Images from the cache are rendered in memory (SDRAM) in global memory-mapped files. The process of
rendering is controlled by the MIM Delivery Interface.
6-3-3-1. MIM Delivery Interface
The MIM Delivery Interface receives the print job (Information Model), then processes and renders the
image data stored on the HARD DRIVE into a full page, edge-to-edge, raster image. After rendering, it
passes the page to the MCS Interface Server (MIS) software for transfer to the MCS. MIM Delivery
Interface supports the following functions:
•
Full page rendering of all supported film sizes, including implementation of image rotation,
magnification, border, time stamp, Dpatch, and annotation.
•
Image processing to create T-values that use the following variables: TimageMin, Timage Max, Dmax,
Dmin, TFT, Contrast, and Polarity, then conversion of these T-Values into laser values.
Figure 6-6 shows the main functions used in rendering the page.
