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

 Detector (height:int, width:int, delx:float, dely:float,
           n_subsample:int|None=None)

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

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