iradon_InterpToUniformAngle

Convert equal solid angle projection scheme into equal linear angle scheme

Syntax:

Pela=iradon_InterpToUniformAngle(Pesa, options);

Description:

To be used in conjunction with iradon_d2d_mstage.
Pesa - equal solid angle scheme projections (float, see below) for 3D: size(Pela)=[points_in_projection, 1, N_Θ, N_φ] for 4D: size(Pela)=[points_in_projection, N_Θ, N_φ, N_α] Number of N_φ^s≤N_φ angles for each N_Θ is given by the formula: N_φ^s=round(abs(N_Θ*sin(Θ))) Missing projections (N_φ^s+1 ... N_φ) are padded with zeros. options - options (string, 'imgData'/'timeStamp') 'timeStamp' : do spline interpolation and then extrapolation 'imgData' : do interpolation using azimuthal symmetry Pela - equal linear angle scheme projections (float, see below) for 3D: size(Pela)=[points_in_projection, 1, N_Θ, N_φ] for 4D: size(Pela)=[points_in_projection, N_Θ, N_φ, N_Θ]
