ZFrameRegistration is a 3D Slicer extension designed to support the workflow of the in-bore MRI-guided therapies (see references below for clinical context).
ZFrameRegistration was developed and tested to support transperineal MRgBx and CryoAblation procedures in the Advanced Multimodality Image Guided Operating (AMIGO) at the Brigham and Women's Hospital, Boston. Its applicability to other types of procedures has not been evaluated.
The registration of the intra-procedural image frame of reference with the transperineal biopsy or cryoablation templates.
-
After install the extension, the user need to switch to the module
ZFrameRegistrationWithROI. -
Load a nrrd file into 3D Slicer by clicking the Slicer
Add Databutton.
-
Choose the volume in the
Zframe template volumeselector.
-
The ROI definition will be automatically triggered if the volume is selected or changed, user needs to define ROI by clicking two points in the slice widget.
-
Press the run algorithm button, the registration will be performed and the zframe model will be shown both in the slice widgets and the 3D view widget.
-
If the result is not good, click the "Reset" button or user the manual start/end indexes. If the "Reset" button is clicked, the user will be prompt to do the ROI definition as in step 3. Afterwards, press the run algorithm button again.
-
When the result looks good, the zframe will align very well with the fiducial artifacts on the slice widgets and the 3D view window.
The user have the option to run the module in a slicelet mode Type the following command in a terminal in Linux or Mac OS system.
$ cd ${Slicer_execution_path}
$ ./Slicer --no-main-window --python-script lib/Slicer-x.x/qt-scripted-modules/ZFrameRegistrationWithROI.py
For Windows system, see the link for more information Slicelet Mode
ZFrameRegistration, same as 3D Slicer, is a research software. ZFrameRegistration is NOT an FDA-approved medical device. It is not intended for clinical use. The user assumes full responsibility to comply with the appropriate regulations.

Development of ZFrameRegistration is supported in part by the following NIH grants:
- R01 EB020667 OpenIGTLink: a network communication interface for closed-loop image-guided interventions
- R01 CA111288 Enabling Technologies for MRI-guided prostate interventions
- P41 EB015898 National Center for Image Guided Therapy (NCIGT), http://ncigt.org
The source code was adopted from the open source projects as follows:
- ProstateNav module of 3D Slicer version 3 (see source code here, no revision history); although we do not have the precise record of contribution to that functionality in the ProstateNav module, we believe main contributors were Junichi Tokuda and Simon Di Maio (while at BWH, now at Intuitive Surgical)
