Consistent Printing
To achieve consistency in image printing
Creating hardcopy output using DICOM basic print
with Presentation LUT Support
Calibrate the hardcopy output devices (printers) using
DICOM Grayscale Standard Display Function
Apply Grayscale Softcopy Presentation State to
control the consistent appearance of images on
softcopy display

High availability
In information technology, high availability
refers to a system or component that is
continuously operational for a desirably
long length of time. Availability can be
measured relative to "100% operational“.
A widely-held but difficult-to-achieve
standard of availability for a system or
product is known as "five 9s" (99.999
percent) availability.
32
99.999% uptime
By calculation
24hr x 60min x 356days = 525600 mins
0.001% downtime = 0.001% x 525600 =
5.256 mins
So if 99.999% availability is required, the only
downtime per year is ~ 5 mins
More reasonable downtime is 52.5 mins
which means 99.99% availability
33
Contingency plan
AED X-ray Contingency Plan for break down of machine (including DR X-ray and CR system)
1. Call respective vendors for service (GE/Agfa/Philips/Fuji etc)
2. Hotline for Services
Agfa 28739335 (Mon-Fri 09:00-18:00) 77780378 (Sat, after office hours and PH)
GE 21006288 (24 hours)
Philips 28215473 (24 hours)
Fuji 61130089 (24 hours)
3. We have enough numbers of CR readers backup, just relocate them after power off and power on again
4. If DR X-ray is down, go to Trauma room 1 for backup
5. If DR Erect detector is down, may continue to use the room, Chest stand and CR is used for Erect Projections
6. If TMHAERW1 is down, shift to TMHAERW2
7. If Broker is down, manual input of Patient name and ID and accession #, verified in TMHAERW1 as usual.
8. If RIS is down, manual input of Patient name and ID and manually sent to Web Server only, do not verified in
TMHAERW1 until all patient demographics are edited afterwards.
9. If Web Server is down, revert to film printing for AED
10.If CMS for AED is down, shift to another workstations as there are total 15 workstations for them to use
11.If the whole CMS system is down, revert to film printing for AED
12.If CS5000 in C2 or AED is down, relocate the backup CS5000 for them (park in Trauma room Control)
13.If AED Network is down, depends on which switch or port is down, may need to continue services in the Main
Department. Please refer to next page for details
Please inform Administrator and mark down the incidents afterwards in the log!
