Objects

TargetObj

class TargetObj(target, target_care_area, resolution, varargin)

This class creates an object that contains projections and relevant properties.

Parameters

• target - 2D or 3D matrix of sinograms

• target_care_area - vector of angles of projection in degrees

• resolution - number of slices in the z-direction

• dim - number of dimensions of the target

• varargin - (optional) stl_filename

Returns

• obj - instance of TargetObj containing the target, dilated target, and z-slice resolution if 3D target. stl_filename is present if the TargetObj was generated from a .stl

ProjObj

class ProjObj(projection, proj_params_used, opt_params_used)

This class creates an object that contains projections and the parameters that were used in creation of the projections.

Parameters

• projection - 2D or 3D matrix of sinograms

• proj_params_used - structure of projection parameters

• opt_params_used - structure of optimization parameters

Returns

• obj - instance of ProjObj containing projections, projection parameters, and optimization parameters

ReconObj

class ReconObj(reconstruction, proj_params_used, opt_params_used)

This class creates an object that contains a reconstruction and the parameters that were used in creation of the reconstruction.

Parameters

• projection - 2D or 3D matrix of reconstruction

• proj_params_used - structure of projection parameters

• opt_params_used - structure of optimization parameters

Returns

• obj - instance of ReconObj containing a reconstruction, projection parameters, and optimization parameters

ImageSetObj

class ImageSetObj(image_set, proj_params_used, opt_params_used)

This class creates an object that contains an image set and the parameters that were used in creation of the image set.

Parameters

• image_set - cell array of images (used for image projection)

• image_params_used - structure of image parameters

• proj_params_used - structure of projection parameters

• opt_params_used - structure of optimization parameters

Returns

• obj - instance of ImageSetObj containing an image set, image parameters, projection parameters, and optimization parameters
