CTLab

Simulation of CT acquisition process and volume reconstruction.

• Points inside the model:

• First projection:

• Phantom visualization:

• Reconstruction using SimpleITK and viewed with napari

• Synthetic Volume rendered in quad view

• Real volume rendered in quad view (QWidgets)

• The quad views are implemented in C++ using Qt/OpenGL and loaded into QML via PySide6.

References: I can't find where the wolf's 3d model came from.

• Dependencies

  CUDA 12.8

  Qt 6.9.1

Running on Linux (Ubuntu 24.04 / Wayland)

If the application crashes on startup with a Segmentation fault due to conflicts between Qt6 and OpenCV's GTK backend, force the application to use the X11 compatibility layer by running the following commands in your terminal before executing the binary:

export QT_QPA_PLATFORMTHEME=generic
export QT_QPA_PLATFORM=xcb
./bin/QuadWidgets

Alternatively, you can run it in a single line:

QT_QPA_PLATFORMTHEME=generic QT_QPA_PLATFORM=xcb ./bin/QuadWidgets
