Helper class: the ASTRAProjector module

+
+
+class astra.ASTRAProjector.ASTRAProjector2D(proj_geom, vol_geom, proj_type, useCUDA=False)[source]
+

Bases: builtins.object

+

Helps with various common ASTRA Toolbox 2D operations.

+

This class can perform several often used toolbox operations, such as:

+
    +
  • Forward projecting
    • +
  • Back projecting
    • +
  • Reconstructing
    • +
+

Note that this class has a some computational overhead, because it +copies a lot of data. If you use many repeated operations, directly +using the PyAstraToolbox methods directly is faster.

+

You can use this class as an abstracted weight matrix \(W\): multiplying an instance +proj of this class by an image results in a forward projection of the image, and multiplying +proj.T by a sinogram results in a backprojection of the sinogram:

+
proj = ASTRAProjector2D(...)
+fp = proj*image
+bp = proj.T*sinogram
+
+
+ +++ + + + +
Parameters:
    +
  • proj_geom (dict) – The projection geometry.
    • +
  • vol_geom (dict) – The volume geometry.
    • +
  • proj_type (string) – Projector type, such as 'line', 'linear', ...
    • +
  • useCUDA (bool) – If True, use CUDA for calculations, when possible.
    • +
+
+
+
+backProject(data)[source]
+

Backproject a sinogram.

+ +++ + + + + + +
Parameters:data (numpy.ndarray or int) – The sinogram data or ID.
Returns:numpy.ndarray – The backprojection.
+
+ +
+
+forwardProject(data)[source]
+

Forward project an image.

+ +++ + + + + + +
Parameters:data (numpy.ndarray or int) – The image data or ID.
Returns:numpy.ndarray – The forward projection.
+
+ +
+
+reconstruct(data, method, **kwargs)[source]
+

Reconstruct an image from a sinogram.

+ +++ + + + + + +
Parameters: +
Returns:

numpy.ndarray – The reconstruction.

+
+

Example of a SIRT reconstruction using CUDA:

+
proj = ASTRAProjector2D(...)
+rec = proj.reconstruct(sinogram,'SIRT_CUDA',iterations=1000)
+
+
+
+ +
+ +
+
+class astra.ASTRAProjector.ASTRAProjector2DTranspose(parentProj)[source]
+

Bases: builtins.object

+

Implements the proj.T functionality.

+

Do not use directly, since it can be accessed as member .T of +an ASTRAProjector2D object.

      MATLAB compatibility interface: the matlab module

      +

      This module implements a MATLAB-like interface to the ASTRA Toolbox.

      +

      Note that all functions are called with a string as the first +argument, specifying the operation to perform. This un-pythonic way +is used to make transitioning from MATLAB code to Python code easier, as +the MATLAB interface uses the same type of method calling.

      +

      After an initial import astra, these functions can be accessed in the +astra.m module.

      +
      +
      +astra.matlab.algorithm(command, *args)[source]
      +

      MATLAB-like interface to the astra.algorithm module

      +

      For example:

      +

      astra.m.algorithm('run',i,1000) – Run an algorithm with 1000 iterations.

      +
      + +
      +
      +astra.matlab.astra(command, *args)[source]
      +

      MATLAB-like interface to the astra.astra module

      +

      For example:

      +

      astra.m.astra('use_cuda') – Check if CUDA is enabled.

      +
      + +
      +
      +astra.matlab.data2d(command, *args)[source]
      +

      MATLAB-like interface to the astra.data2d module

      +

      For example:

      +

      astra.m.data2d('create',type,geometry,data) – Create a 2D object.

      +
      + +
      +
      +astra.matlab.data3d(command, *args)[source]
      +

      MATLAB-like interface to the astra.data3d module

      +

      For example:

      +

      astra.m.data3d('get',i) – Get 3D object data.

      +
      + +
      +
      +astra.matlab.matrix(command, *args)[source]
      +

      MATLAB-like interface to the astra.matrix module

      +

      For example:

      +

      astra.m.matrix('delete',i) – Delete a matrix.

      +
      + +
      +
      +astra.matlab.projector(command, *args)[source]
      +

      MATLAB-like interface to the astra.projector module

      +

      For example:

      +

      astra.m.projector('volume_geometry',i) – Get volume geometry.

      +
