The projection data can be acquired in as little as 5 seconds, or as many as 500 projections can be acquired in 20 seconds.
The mass flow rate of particles derived from extinction principle in some assumption circumstances has shown a good agreement to the projection data of light beams.
A popular mechanism to increase the rate of convergence of these types of algorithms has been to perform the correctional updates within subsets of the projection data.
However, this strategy would inevitably increase the projection data noise, and the resulting image by the conventional filtered back-projection (FBP) method may suffer from excessive noise and streak artifacts.
In traditional 3-D CT reconstruction methods, for the projection procedure is low-pass smoothing, the high-frequency characters are difficult to obtain after the projection data are reconstructed.
After the projection data in the fuel-free zone were extracted, image and graphic processing methods were combined for automatic recognition of escaped coated fuel particles, and some practical inspection results were presented.
The color variant of the classical schlieren technique namely the rainbow schlieren deflectometry has been employed to record the projection data of the temperature gradient field in the test cavity.
The absorbed energy and object mass were individually modeled using the projection data.
This study demonstrated the feasibility of computationally efficient dose estimation requiring only the projection data.
There appears to be an antagonism between increasing nonlinearity and noise in the projection data.
