Detector (C-Arm)

Set up the 7 degrees-of-freedom parameters for the C-arm

Note, the Detector is usually initialized in the DRR module and shouldn’t need to be called directly.



 Detector (height:int, width:int, delx:float, dely:float,

Construct a 6 DoF X-ray detector system. This model is based on a C-Arm.

Type Default Details
height int Height of the X-ray detector
width int Width of the X-ray detector
delx float Pixel spacing in the X-direction
dely float Pixel spacing in the Y-direction
n_subsample int | None None Number of target points to randomly sample



 Detector.make_xrays (sdr:torch.Tensor, rotations:torch.Tensor,

Create source and target points for X-rays to trace through the volume.

Type Details
sdr torch.Tensor source-to-detector radius (half of the source-to-detector distance)
rotations torch.Tensor Vector of C-arm rotations (theta, phi, gamma) for azimuthal, polar, and roll angles
translations torch.Tensor Vector of C-arm translations (bx, by, bz)
