Updated May 5, 2023, for ProKnow DS v1.34.0
1. Conformance Statement Overview
ProKnow DS is a cloud-based RT-PACS (Radiation Therapy Picture/Patient Archiving and Communication System). It enables radiotherapy professionals to archive, inspect, analyze, and interact with radiation therapy patient data for retrospective studies, prospective analysis, and clinical decision support. Although most patient data will be generated and imported from external systems, ProKnow DS also allows users to interact with patient data by performing common tasks such as structure renaming, Boolean operations, and contouring.
ProKnow DS does not support any of the DICOM networking services (transfer, query/retrieve, workflow management, print management). Instead, a user interface is provided to upload and download DICOM files. In addition, ProKnow DS contains a private REST API to receive uploaded files from a client-side application and ProKnow DICOM DS local data services. Table 1-1 identifies the standard SOP classes supported by ProKnow DS.

3.2. Audience
This document is written for the people that need to understand how ProKnow DS will integrate into their healthcare facility. This includes both those responsible for overall imaging network policy and architecture, as well as integrators who need to have a detailed understanding of the DICOM features of the product. This document contains some basic DICOM definitions so that any reader may understand how this product implements DICOM features. However, integrators are expected to fully understand DICOM terminology, how the tables in this document relate to the product's functionality, and how that functionality integrates with other devices that support compatible DICOM features.
3.3. Remarks
The scope of this DICOM conformance statement is to facilitate integration between ProKnow DS and other DICOM products. The conformance statement should be read and understood in conjunction with the DICOM standard. DICOM by itself does not guarantee interoperability. The conformance statement does, however, facilitate a first-level comparison for interoperability between different applications supporting compatible DICOM functionality. This conformance statement is not supposed to replace validation with other DICOM equipment to ensure proper exchange of intended information. In fact, the user should be aware of the following important issues:
- The comparison of different conformance statements is just the first step towards assessing interconnectivity and interoperability between the product and other DICOM conformant equipment.
- Test procedures should be defined and executed to validate the required level of interoperability with specific compatible DICOM equipment, as established by the healthcare facility.
3.4. Terms and Definitions
Informal definitions are provided for the following terms used in this conformance statement. The DICOM standard is the authoritative source for formal definitions of these terms.
Table 3-2. Terms and Definitions
Term | Definition |
Attribute | A unit of information in an object definition; a data element identified by a tag. The information may be a complex data structure (Sequence), itself composed of lower level data elements. Examples: Patient ID (0010,0020), Accession Number (0008,0050), Photometric Interpretation (0028,0004), Procedure Code Sequence (0008,1032). |
Information Entity (IE) | That portion of information defined by a Composite IOD which is related to one specific class of Real-World Object. There is a one-to-one correspondence between Information Entities and entities in the DICOM Application Model. |
Information Object Definition (IOD) | The specified set of Attributes that comprise a type of data object, does not represent a specific instance of the data object, but rather a class of similar data objects that have the same properties. The Attributes may be specified as Mandatory (Type 1), Required but possibly unknown (Type 2), or Optional (Type 3), and there may be conditions associated with the use of an Attribute (Types 1C and 2C). Examples: MR Image IOD, CT Image IOD, Print Job IOD. |
Module | A set of Attributes within an Information Object Definition that are logically related to each other. Example: Patient Module includes Patient Name, Patient ID, Patient Birth Date, and Patient Sex |
Service/Object Pair (SOP) Class | The specification of the network or media transfer (service) of a particular type of data (object); the fundamental unit of DICOM interoperability specification. Examples: Ultrasound Image Storage Service, Basic Grayscale Print Management. |
Service/Object Pair (SOP) Instance | An information object; a specific occurrence of information exchanged in a SOP Class. Example: a specific x-ray image. |
Tag | A 32-bit identifier for a data element, represented as a pair of four digit hexadecimal numbers, the “group” and the “element”. If the “group” number is odd, the tag is for a private (manufacturer-specific) data element. Examples: (0010,0020) [Patient ID], (07FE,0010) [Pixel Data], (0019,0210) [private data element] |
Transfer Syntax | The encoding used for exchange of DICOM information objects and messages. Examples: JPEG compressed (images), little endian explicit value representation. |
Unique Identifier (UID) | A globally unique “dotted decimal” string that identifies a specific object or a class of objects; an ISO-8824 Object Identifier. Examples: Study Instance UID, SOP Class UID, SOP Instance UID. |
Value Representation (VR) | The format type of an individual DICOM data element, such as text, an integer, a person’s name, or a code. DICOM information objects can be transmitted with either explicit identification of the type of each data element (Explicit VR), or without explicit identification (Implicit VR); with Implicit VR, the receiving application must use a DICOM data dictionary to look up the format of each data element. |
3.5. Basics of DICOM Communication
This section describes terminology used in this conformance statement for the non-specialist. The key terms used in the conformance statement are highlighted in italics below. This section is not a substitute for training about DICOM, and it makes many simplifications about the meanings of DICOM terms.
Since ProKnow DS does not support any DICOM networking services, these services need to be provided by other applications. ProKnow DS does provide a user interface and private REST API to upload and download files created and used by these other applications.
DICOM specifies a variety of methods for encoding data and denoting transfer syntaxes. The transfer syntax specifies endianness and whether the value representation for each attribute is explicitly provided or whether it must be determined based on the tag using a DICOM dictionary. Each unit of data is formatted in accordance with the appropriate information object definition, using the transfer syntax.

4. Networking
ProKnow DS does not satisfy the 7.1 DICOM Networking Conformance Requirements defined in PS3.2. Network transfer of data from on-premise clinical systems to the cloud-based ProKnow DS is achieved by utilizing the ProKnow DICOM Agent — a locally installed Windows application. Refer to the ProKnow DICOM Agent support articles for more information.
5. Media Interchange
While ProKnow DS does not fully satisfy the 7.2 DICOM Media Interchange Conformance Requirements defined in PS3.2, it does provide a user interface for uploading and downloading DICOM files. Refer to the Uploads Module and Downloading Patient Objects support articles for more information.
6. Transformation of DICOM to CDA
ProKnow DS does not support any Structured Reporting (SR) objects.
7. Support of Character Sets
ProKnow DS does not support extended character sets.
8. Security
ProKnow DS does not claim conformance to any of the Security and System Management Profiles defined in the DICOM Standard. That being said, data security is one of the most important aspects of the ProKnow DS design. All data transmission both to and from the Internet (including calls to the REST API to upload DICOM files) is encrypted using secure HTTP access (HTTPS) and all communication between servers is encrypted using HTTPS or SSL.
8.1. Security Profiles
No Security Profiles are supported.
8.2. Association Level Security
ProKnow DS does not support Association Level Security.
8.3. Application Level Security
Any users logging into ProKnow DS must identify themselves with, at a minimum, an email and password. It is also possible to utilize multi-factor authentication (enabled at a per-user or organization-wide level) to further enhance security.
