**DICOM Modality Worklist Tester** is a lightweight, standalone utility designed to simulate a Modality (SCU) for testing and verifying DICOM Modality Worklist (MWL) services on a PACS or RIS (SCP).

Built on the robust **Fellow Oak DICOM (fo-dicom)** library, this tool provides a reliable way to query worklists without the need for complex installation or heavy runtimes.

##  Supported DICOM Tags

The application handles the following DICOM tags. You can configure which of these tags are visible in the result grid via the **File -> Settings** menu.

## Requirements

* **OS:** Windows 10 or Windows 11.
* **Framework:** .NET Framework 4.8 (Pre-installed on supported OS).

## Installation

You can choose between the Windows Installer or the Portable version.

### Option 1: Portable (Recommended - does not require administrative privileges)
1. Download the **ZIP file** from the [latest release](../../releases/latest).
2. Extract the files to a folder of your choice.
3. Run `DMWLT4.exe`.

### Option 2: Installer
1. Download the **MSI Installer** from the [latest release](../../releases/latest).
2. Double-click the file to install the application.
3. Launch **DICOM Modality Worklist Tester** from your Start Menu.

### ⚠️ Microsoft SmartScreen Warning
Because this is an open-source tool and is not digitally signed with a paid certificate, you may see a **"Windows protected your PC"** warning (Microsoft Defender SmartScreen) when you try to run the application for the first time.

To proceed:
1. Click **More info**.
2. Click **Run anyway**.

This is a standard warning for unsigned software and does not indicate a security threat.

## Usage

1. **Configure Connection:** Enter the IP, Port, and AE Title of the target Worklist SCP (RIS/PACS).
2. **Set Local AE:** Configure your local Calling AE Title.
3. **Test Connection:** Use the **Ping** or **DICOM Echo** buttons to verify network visibility.
4. **Query:** Enter search criteria (e.g., Modality, Date, or Patient Name) and execute the query.
5. **Review:** Check the results list. You can customize visible columns via **File -> Settings**.
