How do I store the values in the @D array in the below mentioned VI? Only the last row in the Array is populated with values from the image.

[parag77]

Hello Guys,

I am trying to build a sinogram from 180 projection images and I am not able to store the summed values into the array as it is moving the values and then populating all the rows except for the last with ZERO.

Thanks in advance.

Your loop runs only three times, so all you can possibly populate is 3 rows.

Typically, you would initialize a shift register with the initialized array, then use replace array subset, feeding the modified array back into the shift register. However, in this case you could just autoindex the 1D array at the output tunnel to build the resulting 2D array.

Sorry, I am not familiar with sinograms. Do you have a link describing the algorithm?
