该算法采用了线性反投影的原理，作了两处改进。

First, we propose an improved image super-resolution system based on iterative back projection.

首先，我们根据叠代投影方法提出改进的超解析影像系统。

The simulation experiments illustrate that the method effectively improve the back projection speed.

仿真实验表明，这种方法可以有效提高反投影速度。

Back projection display apparatus includes an optical engine, and display screen of back projection.

一种背投影显示装置及其背投影显示屏幕，背投影显示装置包括一光学引擎与背投影显示屏幕，光学引擎所提供的影像光束透过背投影显示屏幕显示影像。

A back projection method of the filtered back projecion algorithm is proposed based on passive raydriven technique and preinterpolation technique.

提出了滤波反投影（filtered back projection， FBP）算法的基于被动式射线驱动和预插值的反投影策略。

A back projection method of the filtered back projecion algorithm is proposed based on passive ray-driven technique and pre-interpolation technique.

According to this,the reconstruction algorithms such as Linear Back Projection,Filter Back Projection and projection rearrangement method cannot be applied directly and must be improved.

根据这一情况，在医学CT中常用的一些图像重建算法如反投影法、滤波反投影法和投影重排方法都必须加以改进才能引用。

When the projection is placed behind a screen (as it is in television and various video conferencing applications where the image is displayed on a monitor or a fabric screen) it is described as a back projection system.

当投影仪放置在屏幕的后方时（就像电视中以及各种电视会议中使用的那样，图像被投影到监控器或编织物屏幕上），称为背面放映系统。

Microstructure-evolution of the silicon nitride ceramics sample during sintering process was investigated by a synchrotron radiation X-ray computed tomography technique. The projection images of the sample were obtained during the sintering process in real-time. 2-D and 3-D reconstructed images were obtained by treating the projection images of different sintering periods with filter back projection arithmetic and digital image processing methods.
