Event reports, and images received from remote Storage SCP’s . In addition, TLS security for incoming DICOM communication may be e nabled, optional encryption enabled/disabled, and certificates imported, selected, or removed from this interface. 4.4.1.2 Remote AE Title/Presentation Address Mapping Remote AE’s may be configured on the PSC – Network/DICOM – DICOM Settings screen. The screen is organized into DICOM Devices, each specified by • The Device Type which indicates the services for which the device is to be used • A Device Name given by the user in order to reference the device elsewhere in the EPIQ/Affiniti user interface • AE Title for the remote AE • Port for the remote AE • Network address, specified either by IPv4 IP address or a Hostname that is resolved by DNS • TLS security for outgoing DICOM communication may be enabled, optional encryption enabled/disabled, and certificates imported, selected, or removed • Additional settings specific to each device type The following Device Types may be configured: Table 4.64 CONFIGURABLE DICOM DEVICES Device Type Supported SOPs DICOM Storage Server Storage SOP Classes defined in Section 4.1.2.1 Study Root Query Retrieve -FIND Study Root Query Retrieve -MOVE DICOM Commit Server Storage Commitment Push Model DICOM MPPS Server Modality Performed Procedure Step DICOM Worklist Server Modality Worklist FIND DICOM Structured Report Server Comprehensive Structured Report Storage DICOM BW Printer Basic Grayscale Print Meta DICOM Color Printer Basic Color Print Meta To configure a single server that supports multiple services, such as image store, storage commitment, and MPPS, a separate “Device” entry must be configured for each service using the correct device type, an appropriate AE Title, Port, and network address . To configure Storage Commitment, define a Storage Server to which objects to be committed will be stored and a Storage Commitment server (which may or may not be the same physical computer). Then, on the DICOM Selection screen, associate this Storage Server with the associated Storage Commitment server. Configuration specific to pa rticular Device Types is described below. 4.4.1.2.1 Image Storage Configuration Multiple remote Storage SCPs can be defined and up to five may be selected simultaneously for export. For automatic export of acquired images during an exam if set to send “After Each Print/Acquire” or at the end of an exam i f set to send “At End of Exam”, a destination device must be enabled in Setups – Acquisition/Capture – Archive/Print screen. This screen allows each capture control to be separately configured for export destination. If a destination device is not enabled for a capture control, any images acquired through that capture control will not be automatically sent to that destination device. E7 and E5/A70 and A50 1.5.x.x DICOM Conformance Statement 000490000000111 Rev A Page 61
Each Storage Server includes a set of Advanced Settings allowing for device-specific control of the data to be stored to that device. These settings include: • Compression to be used for single- frame images • Compression to be used for multi -frame images • Whether to send images in Monochrome or Color photom etric interpretations • Whether to limit export to Implicit VR Little Endian transfer syntax. Generally used only for the few devices that don’t understand any other transfer syntax. • Whether to send Structured Reports to this destination • Whether to send Nat ive Data of various imaging modes to this device. Native Data should not be selected unless the data will be displayed by a workstation using Philips’ QLAB analysis software which is able to understand this data, as the datasets are large and could possibly affecting data transfer performance. • Whether to send Volume data and Philips Proprietary 3D Presentation State to this device. If not enabled, the device would still receive 2D representations of acquired volumes. • Association Timeout settings (see 4.4.1.2.3) • Whether to send Pixel Spacing (0028,0030) with single- mode images to this device. This is in addition to any Region Calibration that may otherwise be sent to this device. Use for allowing measurements to be made on DICOM viewers that don’t understand Ultrasound Region Calibration. 4.4.1.2.2 Structured Report Storage Configuration A Structured Report server is a Storage SCP that only supports and receives reports. To enable this method, create a Structured Report server in PSC – Network/DICOM – DICOM Settings and then select it as the active Structured Report server in PSC – Network/DICOM – DICOM Selection. For Structured Reports to be sent automatically at end exam, the storage destination must be selected for either the Acquire 1 or Acquire 2 keys in Setups – Acquisition/Capture – Archive/Print. If SR support is confirmed using verify and measurements are made during the exam, one or more Structured Reports will be sent to the device . In Support > Network/DICOM > DICOM Settings > Structured Report Global Settings, you may select which Structured Reports to send. Additionally, Link Measurements to Images allows for inclusion of coordinate data with the SR. OB -GYN study types generate OB -GYN Ultrasound Procedure Reports, Vascular or Abdominal study measurements generate a Vascular Ultrasound Report, and the Adult Echo Study generates an Echocardiography Procedure Report. Two types of Pediatric Echo Reports are available depending on configuration: DICOM -standard Pediatric, Fetal, and Congenital Cardiac Ultrasound Report or Philips proprietary Pediatric Echo Report. Note that there may be more than one report instance per exam, so long as they are from different study types. If no separate Structured Report server is configured and the SOP Class fails negotiation on the configured Storage server , then no SR objects will be created, however, a failed job will remain in the queue. This will need to be manually removed. User Defined measurements will now be sent in a Structured report. No Structured Report i s sent for General or Breast measurements. 4.4.1.2.3 Advanced DICOM Device Association Configuration Configuration Settings for all DICOM devices.

Retry delay after no response from storage commit server (hours) o Time interval before a retry attempt when no response has been received from the storage commit server. Factory default value is provided. 4.4.1.2.4 Serial Structured Report Storage Configuration Serial Report data is a non-DICOM representation of Structured Reports which may additionally be exported via a USB – RS -232 adapter cable to a null -modem RS -232 cable to a serial port configured for 115200 baud, 8 bits, No Parity, 1 Stop Bit and Xon- Xoff Flow Control. O utput will be an XML representation of the DICOM Structured Report object . 4.4.1.2.5 Workflow Configuration Multiple Worklist servers may be defined, but only a single W orklist server can be selected at a time on the PSC – Network/DICOM – DICOM Selection page . See 4.2.2.3.1 for the specification of query criteria for worklist queries. Multiple MPPS servers may be defined, but only a single MPPS server can be selected at a time on the PSC – Network/DICOM – DICOM Selection page . No other configuration is required for MPPS servers. 4.4.1.2.6 Hardcopy Multiple remote Print SCPs can be defined, but no more than one Grayscale and one Color Print SCP may be selected at a time. Automatic sending of color images to the color printer and BW images to the BW printer is selectable in Setups – Acquisition/Capture – Acquisition/Capture – Send Images/Clips – Automatic Printer Choice. 4.4.2 Parameters The following parameters apply to all Application Entities.

It is associated with the local real -world activity “Export to Media”. “Export to Media” is performed upon user request for selected studies, performed procedures, or instances (images, 3D Volumes, 3D Presentation States, and Structured Reports) . Throughout this section, the term “Media” refers to any of the media listed below which is in use. EPIQ/Affiniti will support the use of most writ able media including CD-R, CD -RW , DVD -R, DVD+R, DVD- RW, DVD+RW and removable USB Storage Device. DICOM structure will be the same regardless of media used. Note that although –R or +R media may be erased multiple times using “erase”, the space may not b e recovered. If a – R or +R media is “Erased”, the previously written data is no longer available, and only the E7 and E5/A70 and A50 1.5.x.x DICOM Conformance Statement 000490000000111 Rev A Page 64
remaining unwritten space on the media is available for use. This restriction does not apply to + / - RW media. Erasing + / - RW media allows the entire disk’s space to be used. If a – R or +R is erased, it is not usable again for DICOM exports due to reliability concerns associated with DVD media. Only DVD+RW/ -RW can be erased and used again for DICOM export. 5.1.2 Functional Definition of AEs 5.1.2.1 Functio nal Definition of Media Application Entity Using “ Export to… Media” will pass the currently selected studies, exams, or individually selected images to the Media Application Entity. The SOP Instances associated with the selection will be collected into one or more export jobs. The contents of each export job will be written to the installed media. If the capacity of a disk is exceeded, the user is provided a dialog, stating capacity exceeded and to insert another disk. 5.1.3 Sequencing of Real -World Activities At least one image must exist and be selected before the Media Application Entity can be invoked. The operator can insert new media at any time. If no writable media is available, the Media queue management Icon will be Yellow. 5.1.4 File Meta Information Op tions The implementation information written to the File Meta Header in each file is: Table 5.1 DICOM IMPLEMENTATION CLASS AND VERSION FOR MEDIA STORAGE Implementation Class UID 1.3.46.670589.14.10000.105 Implementation Version Name EPIQ-AFFIN_1.05 5.2 AE SPECIFICATIONS 5.2.1 Media Application Entity Specification The Media Application Entity provides standard conformance to the DICOM Interchange Option of the Media Storage Service Class.

5.2.1.2 Real -World Activities 5.2.1.2.1 Activity – Export to Media The Media Application Entity acts as an FSC using the interchange option when requested to export SOP Instances from the local database to media. The contents of the export job will be written together with a corresponding DICOMDIR to media. The user can cancel an export job in the job queue. Writing in multi -se ssion format to CDs and DVDs is not supported; a ny CD or DVD with DICOM data on it will be viewed as read- only and additional information will not be written to the media. USB media can be written m any times. 5.2.1.2.2 Activity – Import from Media The Media Application Entity acts as an FSR using the interchange option when requested to import SOP Instances from media to the local database. The Patient Directory user interface displays the contents of removable media. Exams selected by the user are transferred from the media to the system for review. Objects transferred to the system retain their original SOP Instance UIDs. Patient Directory must be set to display the contents of the Hard Disk before the im ported exam information may be displayed. Note: Structured Repor ts may not be read back into EPIQ/Affiniti. 5.2.1.2.3 Activity – Update to Media The Media Application Entity acts as an FSU using the interchange option when requested to export SOP Instances from the local database to media upon which DICOM data already resides. The system user selects exams from the system’s directory for transfer to media that already contains data. The DICOMDIR is updated allowing access to original and new data. DVD +RW media may be erased at any time, removing all previously recorded data. 5.2.1.2.3.1 Media Storage Application Profiles See Table 5.2 for supported Application Profiles. 5.2.1.2.3.2 Options The Media Application Entity supports the SOP Classes and Transfer Syntaxes listed in Table 5.3 .

TLS authentication may be used with or without TLS encryption – default is with TLS encryption. For outgoing TLS requests where EPIQ/Affiniti acts as a TLS Client, the received server RSA certificate is validated by verifying its digital signature against a certificate in the local Trusted Certificate Authorities store whose Subject matches the Issuer of the received certificate. If requested by the TLS Server, EPIQ/Affiniti will then send the certificate configured for “This System” from the local Persona l store. For incoming TLS connection requests where EPIQ/Affiniti acts as a TLS Server, the certificate configured for “This System” is sent from the Personal store to the client as specified in the TLS protocol. EPIQ/Affiniti always requests a client cert ificate from the TLS Client. Certificates are locally managed. The site administrator may import certificates from media to the Trusted Certificate Authority store for verifying incoming certificates; these may be either CA certificates or self -signed end- entity certificates. The site administrator may also import certificates from media to the Personal store along with the certificates private key for certificates representing ‘This System’. A wide variety of certificate file formats are supported, inclu ding • Base 64 Text: PEM format (.pem, .crt), usually unencrypted but may be encrypted. If encrypted, the encryption password must be provided when importing. • ASN.1 Binary: BER, DER, CER formats (.der, .cer, .crt) • PKCS#12: Encrypted Container for certificates with private keys (.pfx, .p12) . This format is used primarily for the “This System” certificate with corresponding private key. The encryption password must be provided when importing. • PKCS#7: Container for multiple certificates. If there is only one certificate in the container, then the certificate is saved to the user -specified store name. If there are multiple certificates in the container, then the Issuer and Subject names of each certificate are compared; if the names are the same, the certificat e is stored in the Trusted Certificate Authority store, else in the Intermediate Certificate Authority store. The site administrator may also remove previously -imported certificates. The incoming TCP port defaults to port 2762 when TLS security is enabled; this port may be changed by the user if desired.
