tomosipo.geometry.ProjectionGeometry

class tomosipo.geometry.ProjectionGeometry(shape=1)[source]

A general base class for projection geometries

__init__(shape=1)[source]

Create a projection geometry

Methods

`__init__`([shape])	Create a projection geometry
`project_point`(point)	Projects point onto detectors
`rescale_det`(scale)	Rescale detector pixels
`reshape`(new_shape)	Reshape detector pixels without changing detector size
`to_astra`()	Convert geometry to astra geometry
`to_vec`()	Return a vector geometry of the current geometry

Attributes

`angles`	The angles from which projections are acquired.
`corners`	Returns a vector with the corners of each detector
`det_normal`	The detector normal vectors of the geometry.
`det_pos`	The detector positions of the geometry.
`det_shape`	The shape of the detector.
`det_size`	The size of the detector.
`det_sizes`	The size of each detector.
`det_u`	The detector u-vectors of the geometry.
`det_v`	The detector v-vectors of the geometry.
`is_cone`	Is this geometry a cone-beam geometry?
`is_parallel`	Is this geometry a parallel-beam geometry?
`is_vec`	Is this a vector geometry?
`lower_left_corner`	Returns a vector with the positions of the lower-left corner the detector
`num_angles`	The number of angles in the projection geometry
`num_steps`	The number of orientations in the geometry
`ray_dir`	The ray direction of the geometry.
`src_pos`	The source positions of the geometry.
