INTRODUCTION
This document describes the DICOM conformance of Envision NEXT, a specialized Endoscopy Imaging and Reporting application. The system supports DICOM networking to enable seamless integration with Hospital Information Systems (HIS), PACS, and Endoscopy Imaging Systems.
IMPLEMENTATION MODEL
Application Data Flow Diagram
The following diagram illustrates the application data flow between external modalities/archives and the Envision NEXT system.
Application Entities and Data Flow
Envision NEXT operates through a primary Application Entity (AE) that handles both scheduling data and image storage.
Functional Definition of AE
The following table details the Application Entity (AE) title, role, and description.
| AE Title | Role | Description |
|---|---|---|
| ENDOSCOPY_SCP | MWL SCP | Provides Modality Worklist information |
| ENDOSCOPY_SCP | C-STORE SCP | Receives images/videos from modalities |
AE SPECIFICATIONS
AE Title
- Default AE Title: ENDOSCOPY_SCP
- Configurable: Yes
Network Parameters
| Parameter | Value |
|---|---|
| Transport | TCP/IP |
| Default Port | 104 |
| IPv4 | Supported |
| IPv6 | Optional |
