PERK Station (Image overlay to perform/train image-guided needle interventions)
Objective
The objective of this project (PERK Station) is to develop a end-to-end solution implemented as a Slicer 3 module to assist in performing/training for image-guided percutaneous needle interventions. The software, along-with its hardware, overlays the image (CT/MR) acquired on the patient/phantom. The physician/trainee looks at the patient/phantom through a semi transparent mirror showing the image overlay and the CT/MR image appears to be floating inside the body with the correct size and position, as if the physician/trainee had 2D ‘X-ray vision’.
Description
The PERK Station comprises of image overlay, laser overlay, and standard tracked freehand navigation in a single suite. The end-to-end solution software module along-with its hardware, operates in clinical environment, or on the PERK Station training hardware. Image overlay works by a secondary monitor mounted with a semi-transparent mirror at 45 degree angle. Thus, the image displayed on the secondary monitor, gets projected on the mirror, and when seen through the mirror, the image appears to be floating on the patient/phantom.
(Note: To use training mode, developed as practical instruction tool for high school students, use revision 5772.)
The software enables to perform image-guided percutaneous needle biopsies. The workflow consists of four steps:
- Calibration: To register the image overlay device with patient/phantom lying on scanner table. In this stage, the software sends the image to the secondary device, in correct physical dimensions. The software enables the user to translate/rotate the image as seen through the mirror, so that it aligns with the fiducials mounted/strapped on patient/phantom to achieve registration. This fiducial alignment achieves in-plane registration. For registration in z-plane, the image projection plane should be coincident with the laser-guide plane, which is also the plane of acquisition.
- Planning: In this step, the entry and target points are given by mouse-clicks. The software calculates the insertion angle w.r.t vertical and insertion depth.
- Insertion: The software overlays the needle guide on the secondary monitor/mirror to assist the physician/user to perform the intervention. Further depth perception lines appear in gradations of 10mms to help the physician to insert the needle at correct depth.
- Validation: If the needle insertion is needed to be validated, the user acquires a validation image with needle inside patient/phantom. The validation volume/image is loaded to scene. The user can give the actual needle entry and end points to get error calculations.
