Please introduce yourself…

• Who are you• Role/background• Size of hospital/clinic

Introduction

• Take notes in workbook• We give you the tools but you are responsible for

using the tools• Take advantage of us – ask questions

Logging into workstation

• Each user will have a sheet next to workstation with ip address

• We will show you how to use Remote Desktop to access your personal environment

Course objectives

• We will identify best practices for uncovering root causes as well as creating future-proof solutions.– File system management in Sectra PACS– Create and manage DICOM SCPs– Identify and fix some common archive issues– Setup and troubleshoot teleradiology

Objectives Course Segment 1

• Awareness of architectures of different servers

• Interrelation of server components

• How I can be proactive in administering disk space


I am responsible?

Disk Management

• Different server, different disks• WISE• SHS• Imageserver

• Different purpose for different disks• Operating System (C:)• Application (C:,D:)• Image store (I:, J:, K:, …)• Database (F:,G:,H)

• Use your SectraGuard Monitoring login to monitor disk space.

Learned from Segment 1

• Server differences and impact on administration

• Introduction to issues that affect disk space

• Proactive administration of disks


I am responsible?


• Understand where log files are located

• Understand administration of PACS logging

• Differentiate between PACS core logging and SHS logging

2Management

of log files

Management of logging levels

• WISE server logging and MWL logging – command line:

w_ping –L #

w_config_mwlscp

• DICOM SCP’s – DICOM Server Toolbox

• SHS – Enterprise Manager

Log File Management

• Log folders – sized initially for PACS operation.

• Specific Logging locations:• PACS Core logging:

C:\Program Files\Sectra\{service}\log

• SHS loggingStandard logs: C:\Program Files\Sectra\log

• Additional Logging administered in Enterprise Manager

• When logging via Enterprise Manager create log destinations on your local workstation

• Turn down DICOM Server log levels unless trouble-shooting

• On core servers logs are stored in C:\program files\sectra\<service>\logs\saved

• Use your Sectra Guard Monitoring account to respond to warnings before issues become critical

Log File Management


• Location of various log files

• How to create SHS destinations and interests

• How to clean up log files to gain disk space

2Management

of log files


• Understand how administrative activity impacts disk use

• Understand need to handle third-party applications

• Understand how to avoid introducing problems through administrative actions

3System/


System/Application/User Files

• PACS is sized for PACS

• SectraGuard Monitoring

• User files should either be stored on a user workstation, or on a share

• If installing several 3rd-party applications, an extra local drive should be added


• When deciding on 3rd party apps, be aware of the data they generate, not just install size

• A word about anti-virus software and updates

• How do I know what is using my disk space?• Manual Effort• More 3rd party apps (e.g. windirstat)


• Awareness of how administrative activity impacts disk use

• How to proactively manage disk space

• How to use tools to manage disk space

3System/



• Learn to better manage short-term storage

• Understanding stages of image import and how they affect disk space

• Understand how to manage DICOM SCPs and base folders to best use disk space


• Logging and applications remain fairly static

• Growth in a facility usually implies growth in modalities and, therefore, number of images

• Exams keep getting bigger

• It’s important that the PACS administrator understand how to manage DICOM servers

DICOM Server Management

• Image storage• SCP/SCU• in_dcm• Autofiler

• All DICOM communication requires:• Host• Port• AE Title

• Sectra PACS establishes storage location using the concept of base folders



Prerequisite – Base Folder

A base folder is required before a DICOM SCP can function.

A base folder is a friendly name for a shared disk location.

Base folders are created from the Windows command line with the command: w_basefolder


EXAMPLE:To create a base folder called R3_MR on a server called “pacs2” in a folder with a share name of “folders$” you would use the command:

C:\> w_basefolder NAME=R3_MR LOCATION=file:\\pacs2\folders$\R3_mr ID_STRING=R3_MR

NOTE: the “file:” preceding the location is required!


• A base folder can have a friendly name, for example “Room3_MRI” – although, the shorter, the better

• Each base folder requires NAME LOCATION ID_STRING (usually the same as NAME)


Configuration:• PACS Infrastructure• DICOM Server Toolbox• Licenses

DICOM Server Management – Autofiler

• Autofiler must be administered effectively

• Autofiler must be updated with each new DICOM SCP

• Autofiler has two halves:• Auto archive• diskcheck


• Understanding of image import process

• Expertise in configuring DICOM servers

• Understanding of how stages of image import affect disk space

• Understanding need to keep autofiler in step with DICOM server management



• What does archiving mean and how is it used within Sectra PACS

• What are common reasons for archive job failure.

• How do we troubleshoot and solve archive job failure.


jobs

What does archiving mean

• Archiving saves space• Slower storage media is cheaper• Exams get locked from editing• To access an archived exam it has to first be retrieved

from archive media

Archive Jobs alert from Sectra Monitoring

Archive Jobs alert in Sectra Monitoring

Common reasons for failed archive jobs

• Network outage• Exam administration needed• Unsupported DICOM format• Troubleshooting

– Look at the exam in IDS7– Logfile

C:\Program Files (x86)\sectra\ImageServer\log\ImageServer7831.<date>.txt

– For XD archive there is also DICOM SCP log on archive host.


• What archiving means and how it is used within Sectra PACS

• Common reasons that can cause archive jobs to fail

• How to troubleshoot and clear failed archive jobs


jobs


• What is teleradiology?

• How do we configure teleradiology destinations

• How can we troubleshoot teleradiology


up and troubleshoot

Teleradiology

• Send exams to DICOM receiver• Configured using command line tool w_config_telerad• IP, port and AET (Application Entity Title)

Troubleshooting Teleradiology

• dicom_echo– Tests the DICOM connectivity to a destination.– Requires IP, AET and port for the destination.– dicom_echo –v –c AET <IP> <port>

• Log files– Receiving Telerad

• C:\Program Files (x86)\sectra\ImageServerS\log\ctnstore.xxx.<date>.txt

– Sending Telerad• C:\Program Files (x86)\sectra\WISE\log\ImageServer7832.<date>.txt


• What teleradiology is.

• How to configure teleradiology destinations

• How to troubleshoot teleradiology
