The ProstateNav module is designed to add an integrated user interface (UI) for MRI-guided prostate intervention (e.g. needle biopsy and brachytherapy) to 3D Slicer. Like all of Slicer it is not FDA approved and only intended for research. In version 3.6, the module provides user interfaces for the following devices:
- MRI-compatible pneumatic needle placement robot for transperineal prostate biopsy and brachytherapy (Johns Hopkins University + Brigham and Women's Hospital + Queen's Univeristy)
- MRI-compatible transrectal needle biopsy device (Queen's University + Johns Hopkins University)
- Template-based needle guiding system for MRI-guided prostate biopsy and brachy therapy (Queen's University + Brigham and Women's Hospital)
The module has wizard-style interface, which helps an operator follow the clinical procedure step by step. It supports target planning and management, patient-device registration, and verification. The module can also communicate with some of the devices listed above using OpenIGTLink protocol.
The ProstateNav switches its user interface based on the device type selected by the user. This section describes step-by-step instruction.
Template-based needle guiding system for MRI-guided prostate biopsy and brachy therapy
Step 1: Create a manager node and select a device type
First, create a manager node by choosing Create New ProstateNavManager from a node selector menu in Active configuration. Then click Create New TransperinealProstateTemplate from Robot node selector.
Step 2: Calibration
Press Cliabration button in the workphase tab to open 2/4 Calibration page.
First, we load a multi-slice Z-frame image to register the device coordinate system to the image coordinate system. Choose "File->Add Volume..." menu to open the file selection dialog box.
To display a model of Z-frame fiducial frame in the 3D viewer, click Show Z-frame check box.
Before run automatic Z-frame registration, scroll the all slices in the multi-slice Z-frame image to identify the range of slices that show clear Z-frame images. If you want to adjust the slice range, input the start and end slice index in the text box.
To start automatic Z-frame registration, press Perform Calibration button. It takes a few seconds or more depending on the environment and number of slices. Once the Z-frame is registered to the image coordinate system, the z-frame model is overlaid to the Z-frame image in the 3D view.
Step 3: Targeting
To start targeting, open Targeting button in Workphase panel or Next button in the Calibration Page.
By clicking Needle and Template check buttons, models of the needle and the template can be displayed in 3D viewer.
For the needle placement planning, load a target volume from File->Add Volume... menu.
To place a target point, simply click at the point on the axial image. Make sure Add Target by Image Click check box before you click the image.
To choose a template hole for needle insertion, choose a target point from the list and press Move button at the bottom of the module's user interface. The index of the hole shows up on the panel.
