SECTION 2 CTEX SERVICE PROGRAMS
Several R level programs exist within CTEX (CT EXECUTIVE or User Software) at Directory T13. These
programs, except for ERLG and FK, should only be used as a last resort as data may be deleted.
WARNING: USE OF CLEAN-UP PROGRAMS RCLEAN (RCLEANP) IS DANGEROUS AS LOSS OF IMAGE
DATA WILL RESULT. USE ONLY AS DIRECTED IN THE FOLLOWING PARAGRAPHS.
NOTE: These programs are intended for service use ONLY. Because improper use may delete patient images,
use only as instructed.
If a SLCF is deleted, it may be reinstalled on the system queue using the program RQ in Directory T13.
This program is self prompting and asks you for the SLCF number to install.
2-1 - RECON SHUTDOWN
The message RECON SHUTDOWN indicates image reconstruction was attempted and failed. Basically there are
three reasons for RECON SHUTDOWN.
1. The disk is full (a message, disk full, is usually displayed). or
2. The array processor microcode is corrupt or a hardware fault was detected.
3. Image data on the Recon Queue is bad.
If the disk is full, archive image data to tape to allow room for recon. If image data is bad, use the process
described here to try to save the images.
If the AP is at fault, (see error log) exit from “M” level and reload APM (array processor microcode) by
executing UPAP within Directory DZ0.
The software tries to reconstruct each image three (3) times before printing the message RECON FAILURE.
After three (3) images on the RECON QUEUE have failed (three times each) the message RECON
SHUTDOWN will appear and an asterisk appears next to the last image that failed. If, for example, there are
nine images on the RECON QUEUE and the asterisk is next to image 3 when the RECON SHUTDOWN
message appears, this indicates the first three images (1, 2, and 3 are bad. Images 4 through 9 may still be
good! Therefore, DO NOT USE RCLEAN. The proper procedure is to re-prioritize the images on the queue
so image 4 is 1st priority etc. and images 1 through 3 are the last priority. Exit M level to R level and return
to M level. (When you re-enter M level, RECON will automatically resume.)
If RECON SHUTDOWN occurs for images 4, 5, and 6, again re-prioritize the queue, exit M level to R level,
and re-enter M level. Repeat this process until all images on the queue have attempted RECON. All good
images on the queue will have been reconstructed and only bad images will remain on the queue. At this
point, you have no choice but to delete all images on the queue using RCLEAN and to clean up the image
data base using CUIDB. However, this should only be done after the queue has been saved on tape using
the program BAD SAVE.
To enter these programs from R level, enter “DIR T13 return” followed by “HELPS return” to display the following
