IDI Overview

IDI Overview

Product Description

The IDI is an intelligent interface that connects the SONOS system to a magnetic­optical disk, network storage server, or DICOM-compliant printer located on a local area network (LAN). The IDI is an option to the Philips SONOS 7500 or SONOS 5500 system.
The IDI receives digital image studies that have been stored on the SONOS hard disk. These stored studies can be sent, over a standard 10/100BaseT LAN, to the following devices:
• EnConcert network storage server
• DICOM network storage server and a DICOM printer (optional)
• SONOS system’s optical disk

Physical Description

The IDI works on a personal computer (PC). It includes a hard disk that is shared between the PC and the ultrasound system. The IDI is connected to the ultrasound system via a SCSI cable and to the network via a network connector located on the back of the system. The hard disk is used as a storage buffer before transferring studies to the magnetic-optical disk, network storage server, or DICOM-compliant printer. The hard disk also provides short-term local storage for “portable” ultrasound studies (studies that are conducted while the ultrasound system is physically disconnected from the network). All IDI operations are performed using the function keys and touch panel controls on the ultrasound system.

c12rev98%.fm
Using Integrated Digital Interface (IDI)
IDI Overview

Image Storage and Transfer

The SONOS system creates and stores an image, calibration data, and measurement and calculation data. The system can send data in DICOM format or DSR-TIFF format (to an EnConcert network). Image data sent to an EnConcert network includes calibration data and measurement data. Image data sent in DICOM format includes only calibration data. The same image data transfers in either case, though the image file format differs.
Storing digital studies to disk: You can choose between the SONOS system’s optical disk or hard disk to store studies. However, image storage saves to the hard disk by default when the IDI option is present, to enable studies to be transferred to a network storage server. See “Enabling the Optical Disk as the Storage Device” on
page 30.
Retrieving patient information: You can choose a study that has been on either EnConcert or a DICOM Modality Worklist Server, depending on the system options. See “Retrieving Patient Information (EnConcert or DICOM Modality
Worklist Server)” on page 31.
Storing calibration data: Calibration data provided by the ultrasound system for an image is embedded in the image data that is transferred to either the EnConcert or DICOM network storage server.
Storing numeric measurement data: QuickCalcs and Analysis measurements performed on an image are stored on the hard disk. QuickCalcs measurements are stored with the images on the EnConcert network storage server. Analysis measurement data are stored—with their labels—with the images on the EnConcert network storage server. You can display these measurements or include them in an analysis report on an EnConcert network storage server. If your system is connected to a DICOM network storage server, measurement information is not included.

IDI Overview
Disk Manager: A Philips service representative sets the Disk Manager function
based on customer preference during system installation.
•If Disk Manager Auto is selected, studies are automatically deleted once they are transferred to the network storage server.
•If Disk Manager Off is selected, these studies remain on the hard disk until they are manually deleted.
•If Disk Manager Defer is selected (default), studies are not deleted after transfer but remain on the hard drive. The system monitors hard drive storage capacity. When near-full capacity level of the hard drive is reached, the system automatically deletes the studies previously transferred to the network. You can retrieve studies that are still on the local hard disk and review them on the ultrasound system. You cannot retrieve a study once it has been deleted from the hard disk.

Operation

IDI Availability: IDI takes longer to power up than the ultrasound system, so some
IDI functions may not be immediately available. The status message reads: “The Network Interface is powering up. This normally takes several minutes. Please wait and try again.”
• You receive the above status message if you attempt to perform any of the following functions during the power-up cycle:
• Initialize a hard disk or an optical disk
• Format a hard disk or an optical disk
• Copy images from the hard disk to the optical disk using the Copy to Optical
control
• Rescue a study using the Rescue Study control
You can retry these operations until you no longer receive the error message and you are able to complete the storage operation.
• You receive the following status message if you attempt to end a study using the End Study control during the power-up cycle:
The network interface is not powered-up yet:
* You may wait a few minutes and select “Retry Send.”
* If you cannot wait, select “Save Locally” to
leave the study on the hard disk. To send this
untransferred study at a later time, use
“Rescue Study.”
Retry Send
Save Locally
You should wait for the IDI to complete its bootup sequence and try again. You can start a study and acquire images during this time, but you cannot complete the study using the End Study control.
• You receive the message “The disk is not ready. Please try again later.” if the IDI PC is not working or if it is running a disk-check (Chkdsk) operation.

Device Selection: The Enable Optical control is part of the Disk control set.
Setup
By default, it is not highlighted when IDI is present—that is, the optical disk is not enabled. This configuration follows the assumption that users who have an ultrasound system with IDI will use the network storage server (rather than the optical disk) to store studies. However, if you touch Enable Optical to highlight it, you can choose between the system’s internal hard disk and the optical disk for storage or retrieval. Once you make a selection, all subsequent digital storage is automatically sent to that device until the study is ended or another study is started.

Note that if Enable Optical is turned off in the middle of a study on the hard disk, all subsequent disk operations for that study operate on the hard disk. If Enable Optical is turned off during a study on the optical disk, that study is ended and future disk operations are performed on the hard disk. Enable Optical is a system wide setting—once you set it remains on until you disable it.

Using Integrated Digital Interface (IDI)
IDI Overview
Patient ID Information: Before you start your study, you enter patient information
by pressing Patient ID. If your system is connected to a DICOM Modality Worklist server or an EnConcert network storage server, and the study is ordered, you are presented with a patient selection list. When you choose the patient from the selection list, the Patient Information screen appears with the data filled in. Otherwise a blank Patient Information screen appears and you can enter the patient data manually.
NOTE
After choosing a patient from the Patient Selection list, the Medical Record Number (MRN) field and the accession number on the Patient Information are grayed out to indicate that you cannot modify this information on the SONOS system.
End Study: The End Study Control is part of the Disk and Stress control sets. When you touch the End Study control, IDI:
•Completes the transfer of the study from the IDI internal hard disk to the network storage server
•Writes analysis data to the disk (with DSR-TIFF format)
•Clears all Patient ID information including analysis data and annotation text
•Clears all loops from loop memory
You must touch End Study at the end of each study, even portable studies, or the study does not transfer properly. If you do not press End Study, you are presented with the following dialog box when attempting to start a new study by pressing the “New Patient” key. (Neither the End Study nor the Save Locally option causes analysis data to be lost.).
You have changed to a new patient but have not
ended the previous study:
* To end that study, select “End Study.”
* To leave that study on the hard disk, select
“Save Locally.” To send this untransferred
study at a later time, use “Rescue Study.”

Using Integrated Digital Interface (IDI)
IDI Overview
When you touch End Study, all Disk controls are unavailable until the study has been stored to disk. Once the study has begun its transfer to the network storage server, an icon appears displaying the transfer status. What icon appears depends on the network settings and the network activity. The possible icons are shown in the following table.
Icon Network Activity
When storing loops to disk, the icon indicates the percent progress of the transfer. When several loops are queued, the percentage indicates the storage progress. If a single
99%
frame is being transferred, the percent complete value is not displayed.
With Network Autosend on, the icon indicates that the network is available.
With Network Autosend on, the icon indicates that the network is unavailable.
With Network Autosend off, the icon is blank.
If the network is unavailable, for example, during a portable study, or the network is disconnected during a study, IDI simply queues studies for transfer to the network storage server or printer for a later time. In the background, the system periodically attempts to re-connect to the network storage server or printer. All studies are properly transferred once the network becomes available. If network activity is abruptly aborted (for example, by an On/Off/On power cycle), all studies are properly transferred when the network connection is re-established.
10 Revision D.0
c12rev98%.fm
Using Integrated Digital Interface (IDI)
IDI Overview
When you indicate that a study is over by touching End Study, one of the following actions occur:
•If Disk Manager Off is selected, studies remain on the hard disk even after they are transferred to the network storage server. This configuration gives you the ability to retrieve the studies at any time and edit and review them at the ultrasound system. (See the System Basics guide for information on reviewing a study.) However, you must manage the internal hard disk space by routinely checking disk space and deleting studies.
•If Disk Manager Auto is selected, studies are automatically deleted once they are transferred to the network storage server. This configuration enables IDI to automatically manage the hard disk space. However, since the studies are deleted from the hard disk after they have been successfully transferred they are not available for retrieval and review at the ultrasound system. (The studies are available for retrieval until they are deleted.)
•If Disk Manager Defer (default) is selected, studies remain on the hard disk even after they are transferred to the network storage server. This configuration lets you retrieve, edit, and review the studies at any time on the ultrasound system. (See the System Basics guide for information on reviewing a study.) The system automatically manages the internal hard disk space by routinely checking disk space and deleting studies when the available disk space is too low.
Although a file has been automatically deleted from the hard disk, under certain conditions an entry may remain in the database. If you attempt to retrieve a file that has been deleted, the following message may appear:
“File does not exist. Press Disk. Select Rebuild Database. Choose the Reconcile Option.”
Reconciling the database gives you an accurate list of studies that are on the hard disk.

Using Integrated Digital Interface (IDI)
IDI Overview
When either Disk Manager Auto or Disk Manager Defer is enabled, the internal hard disk does not fill up unless:
• A large number of “portables” are performed before the LAN cable can be reattached
• A large number of studies are stored on the hard disk
• Studies with large amounts of data are stored on the hard disk
When Disk Manager Off is selected, you are responsible for ensuring that the hard disk does not fill up. If the disk does reach capacity, the optical disk can be used for storage.
Untransferred Studies: There are certain rare conditions under which a study can become “stranded” on the hard disk. Stranded means that the study has been saved to the hard disk, but the study has not been queued for transfer to the network storage server. In this case it must be transferred to the network storage server using the Rescue Study control.
NOTE
After you touch End Study, the patient information is removed from the screen while the study transfers to the network DICOM or EnConcert server. This is not an indication the data transfer is complete. You must wait until End Study functionality returns to the touch screen before powering off the SONOS system. The study is then transferred to disk at the next power-up.
When the End Study touch control returns, the study has been sent to the hard disk drive. This has no correlation with the network transfer status. To monitor network transfers, open the Stat us box and wait for the Network Done message to indicate that transfer is complete.

IDI Overview
If the system was Reset/Power-On without ending a study that was in progress, the SONOS system displays a warning dialog box. When storing to the hard disk, the following warning message appears:
A study was in progress before the system was reset:
* To end that study, select “End Study.”
* To leave the study on the hard disk, select
“Save Locally.” To send this untransferred study
at a later time, use “Rescue Study.”
End Study
Save Locally
This message gives you the option to:
End Study—This ends the study and queues it for transfer from the IDI hard disk to the network storage server.
Save Locally—This leaves the study on the hard disk. You can transfer the hard disk study to the network storage server using the Rescue Study control at a later time.
NOTE
It is best to choose End Study when possible.
If the Reset/Power-On situation storing to the optical disk, the following warning dialog box message appears.
A study was in progress before the system was reset:
* To store the analysis data to the optical disk,
select “End Study.”
* To delete the analysis data, select “Discard.”
