Key Investigators
- Brigham and Women's Hospital: Atsushi Yamada, Loïc Cadour, Junichi Tokuda and Nobuhiko Hata
Objective
- For showing MRI which will be taken in realtime at a tip of the needle to a surgeon in prostate biopsy, we will track the tip of the needle and control the scanner by using the tracked position data automatically.
Approach, Plan
- Tracking: Develop a tracking program by using OpenCV
- Control: Develop a server to send the tracked position data to 3D Slicer
- Receiver: Develop a receiver to obtain MRI from a scanner
Progress
- I received raw images from a scanner simulator and showed the received image on the 3D view of Slicer by using OpenCV.
- For sending the tracked position of the tip of a needle of a prostate biopsy, I modified transform matrix in using process timer event.
- For an experimental movie, the tracking of the tip of the needle was executed.
- For an clinical case movie, a low pass and high pass filter was implemented and tested to detect the tip of the needle easily.
