Sentence examples for back projector from inspiring English sources

If the estimated activity from a simulated reconstructed sphere is close to the reference value it means that the back projector is properly normalized.

The purpose of reconstructing simulated data is to isolate any causes of inaccuracy to either the forward projector or back projector.

By use of the back projector system, the image was projected onto a screen above the monkey's head with a liquid crystal display projector (NEC NP 1150, 1024 × 768 visual resolution, 60-Hz refresh rate).

Owing to the image quality in terms of contrast and colour homogeneity, and difficulties in adequate contrast and size calibration, we changed to a back projector-based system soon after.

As opposed to the MC-based forward-projector, the back-projector model includes several approximations.

Hence, the back-projector often must be derived in a more simplistic fashion.

For example, including attenuation modelling in the back-projector often has only a small effect on the reconstruction results, while it is generally beneficial to model the spatial resolution in the back-projector [41, 42].

The combination of an MC-based forward-projector and a simplified analytical ray-tracing back-projector produced quantitative images of acceptable image quality.

One area of potential further development is improvement of the model of the pinhole in the back-projector by accounting for its finite size.

It has been demonstrated that approximations can be introduced into a back-projector as long as the model used in the forward-projection is accurate.

The combination of a Monte Carlo-based forward-projector and a simplified analytical ray-tracing back-projector produced quantitative images of acceptable image quality.
