FluoroSim

An interventional radiology geared fluoroscopy simulator using a raspberry pi3 with webcam

Parts

Raspberry Pi 3
Microsd card
Webcam (we use Logitech C270, although any v4l2 compatible webcam will work)
USB light (or any lighting to adequately illuminate the phantom)
Foot pedal (any momentary foot switch can be used, alternatively the space-bar on a keyboard can be used)
Phantom (created from transparent polyethylene tubing and Loctite plastics binding system)
HDMI monitor

Install raspbian on the microsd card to be placed in the raspberry (Detailed instructions can be found here: https://www.raspberrypi.org/documentation/installation/installing-images/ )
Install OpenCV along with python bindings
Install the RPi.GPIO library https://pypi.python.org/pypi/RPi.GPIO for use of the foot pedal
Connect the foot pedal to GPIO4 (Pin #07) and DC Power 3.3V (Pin #01) on the Raspberry Pi. If needed you may change these in the fluoro-simulator.py file to reflect your requirement
Download fluoro-simulator.py and run with "python fluoro-simulator.py" from the terminal
To automatically run at boot time edit ~/.config/lxsession/LXDE-pi/autostart and append the command "@python fluoro_sim.py", adjust accordingly for your path to fluoro_sim.py

Choose an overlay image that is appropriate for your transparent phantom. Place the overlay image into the same directory as fluorosim.py and name it according the OVERLAY_IMAGE variable, which comes preset as skel.jpg. Four our demo we use an abdominal radiograph from wikipedia found here: https://en.wikipedia.org/wiki/Abdominal_x-ray https://en.wikipedia.org/wiki/Abdominal_x-ray#/media/File:Medical_X-Ray_imaging_ALP02_nevit.jpg
