Overview of what the module does goes here.

The ProstateNav module is designed to add an integrated user interface (UI) for MRI-guided robotic intervention (e.g. needle biopsy and brachytherapy) to 3D Slicer. The module has Wizard-style interface, which provides the operators the step-by-step navigation to follow the clinical procedure of the clinical prostate intervention. The module also provides several functionalities to follow the procedure, including calibration of the robot using fiducial-based registration, target management, and communication with devices (MRI-compatible robot and MR scanner) using [[Modules:OpenIGTLinkIF-Documentation-3.4| OpenIGTLink]].

====Wizard interface====
 +
The interface consists of six pages, corresponding six phases in the procedure:
 +
 
 +
*'''START-UP.''' Software and hardware systems are initialized in this workphase. The 3D Slicer reads a configuration file that defines data stream among the components. Meanwhile, the robot is set up by connecting the pneumatic system to pressurized air, connecting the device to the control unit, and attaching sterilized needle driver kit and needle to the robot. The needle is adjusted to a pre-defined home position of the robot. The imaging coil is attached to the patient, who is then positioned in the scanner.
 +
*'''PLANNING.''' Pre-procedure 3D images, including T1- and T2-weighted images, are acquired and loaded into the 3D Slicer. Target points for needle insertions are interactively defined on the pre-operative images.
 +
*'''CALIBRATION.''' The transformation that registers robot coordinates to patient coordinates is calculated by acquiring images of the Z-shape fiducial frame. The calibration procedure is performed for every intervention by the operator. Once the robot coordinate system is registered, the robot control unit and the 3D Slicer exchange target positions and the current position of the needle using the image (i.e., patient) coordinate system. Details of the Z-shape fiducial will be described in the following section.
 +
*'''TARGETING.''' A current target is selected from the targets defined in the PLANNING workphase, and sent to the robot control unit. The robot moves the needle to the target while transmitting its current position in real time. After the needle guide is maneuvered to the desired position, the needle is manually inserted along an encoded guide to the target lesion. The insertion process is monitored through semi real-time 2D image, automatically aligned to the plane along the needle axis.
 +
*'''MANUAL.''' The operator can directly control the robot position remotely from the 3D Slicer. The system enters this workphase when the needle position needs to be adjusted manually.
 +
*'''EMERGENCY.''' All robot motion is halted for safety reasons, as soon as the system enters the EMERGENCY workphase. The actuators are locked in this state to prevent unwanted motion and allow manual needle retraction.
 +
 
 +
The unique feature in this wizard interface is a set of "jump buttons" placed above the wizard. The buttons not only allow the users to jump from one phase to another, but restrict certain critical phase transitions by disabling the buttons. For example, jumping from START-UP phase to TARGETING should not happen, because it is risky to control the robot before the calibration. Therefore, the button to jump to the TARGETING phase is disable, while the module is in the START-UP phase.
 +
 
 +
====Fiducial-based registration====
 +
To transform a position from the image coordinate system to the robot coordinate system, or vice versa, a calibration is performed by registering the Z-shape fiducial frame attached to the robot in the image coordinate system. The Z-shape fiducial frame is designed to be localized from a single 2D image intersecting the frame. The position and orientation of the Z-shape fiducial frame provide the transformation between the image and robot coordinate systems. Once the transformation is calculated, the needle position and orientation measured by the encoders of the robot can be transformed to image coordinates. The rigid structure of the fiducial frame is made up of seven rigid glass tubes with 3 mm inner diameters that are filled with contrast agent (MR Spots, Beekley, Bristol, CT) and placed on three faces of a 60 mm cube. The ProstateNav module can load 2D sectional image of the Z-frame in DICOM format and calculate its orientation and location in the image space. The image should have field of view (FOV) of 160mm and matrix size of 256 by 256.

Module Description

The ProstateNav module is designed to add an integrated user interface (UI) for MRI-guided robotic intervention (e.g. needle biopsy and brachytherapy) to 3D Slicer. The module has Wizard-style interface, which provides the operators the step-by-step navigation to follow the clinical procedure of the clinical prostate intervention. The module also provides several functionalities to follow the procedure, including calibration of the robot using fiducial-based registration, target management, and communication with devices (MRI-compatible robot and MR scanner) using OpenIGTLink.

Wizard interface

The interface consists of six pages, corresponding six phases in the procedure:

  • START-UP. Software and hardware systems are initialized in this workphase. The 3D Slicer reads a configuration file that defines data stream among the components. Meanwhile, the robot is set up by connecting the pneumatic system to pressurized air, connecting the device to the control unit, and attaching sterilized needle driver kit and needle to the robot. The needle is adjusted to a pre-defined home position of the robot. The imaging coil is attached to the patient, who is then positioned in the scanner.
  • PLANNING. Pre-procedure 3D images, including T1- and T2-weighted images, are acquired and loaded into the 3D Slicer. Target points for needle insertions are interactively defined on the pre-operative images.
  • CALIBRATION. The transformation that registers robot coordinates to patient coordinates is calculated by acquiring images of the Z-shape fiducial frame. The calibration procedure is performed for every intervention by the operator. Once the robot coordinate system is registered, the robot control unit and the 3D Slicer exchange target positions and the current position of the needle using the image (i.e., patient) coordinate system. Details of the Z-shape fiducial will be described in the following section.
  • TARGETING. A current target is selected from the targets defined in the PLANNING workphase, and sent to the robot control unit. The robot moves the needle to the target while transmitting its current position in real time. After the needle guide is maneuvered to the desired position, the needle is manually inserted along an encoded guide to the target lesion. The insertion process is monitored through semi real-time 2D image, automatically aligned to the plane along the needle axis.
  • MANUAL. The operator can directly control the robot position remotely from the 3D Slicer. The system enters this workphase when the needle position needs to be adjusted manually.
  • EMERGENCY. All robot motion is halted for safety reasons, as soon as the system enters the EMERGENCY workphase. The actuators are locked in this state to prevent unwanted motion and allow manual needle retraction.

The unique feature in this wizard interface is a set of "jump buttons" placed above the wizard. The buttons not only allow the users to jump from one phase to another, but restrict certain critical phase transitions by disabling the buttons. For example, jumping from START-UP phase to TARGETING should not happen, because it is risky to control the robot before the calibration. Therefore, the button to jump to the TARGETING phase is disable, while the module is in the START-UP phase.

Fiducial-based registration

To transform a position from the image coordinate system to the robot coordinate system, or vice versa, a calibration is performed by registering the Z-shape fiducial frame attached to the robot in the image coordinate system. The Z-shape fiducial frame is designed to be localized from a single 2D image intersecting the frame. The position and orientation of the Z-shape fiducial frame provide the transformation between the image and robot coordinate systems. Once the transformation is calculated, the needle position and orientation measured by the encoders of the robot can be transformed to image coordinates. The rigid structure of the fiducial frame is made up of seven rigid glass tubes with 3 mm inner diameters that are filled with contrast agent (MR Spots, Beekley, Bristol, CT) and placed on three faces of a 60 mm cube. The ProstateNav module can load 2D sectional image of the Z-frame in DICOM format and calculate its orientation and location in the image space. The image should have field of view (FOV) of 160mm and matrix size of 256 by 256.
