Error code using iradon
显示 更早的评论
I keep getting the error message in my script below when using iradon. How would I resolve this error?
I0 = 10^4;
noAngles = 590;
step = 180/noAngles;
theta = step:step:180;
Y = radon(whatisit,theta)/255;
NoisyRMphantom_Proj = -log(NoisyRMphantom_Trans./I0);
FBPnoisyRM = iradon(NoisyRMphantom_Proj,theta,'linear','Ram-Lak',1,751);
%Error using iradon>parse_inputs (line 346)
%THETA does not match the number of projections.
%Error in iradon (line 119)
%[p,theta,filter,d,interp,N] = parse_inputs(args{:});

- If theta is a vector, then specify R as a 2-D matrix in which each column is the Radon transform for one of the angles in theta.
Your theta is a vector, so your input R (first parameter) should be an array that has the same number of columns as theta has entries.
Your theta has 590 entries (noAngles), so your R should have 590 columns. But instead it has 360 columns.
