E - e望遠鏡方法對同量異位素的分辨本領取決于e和e探測器的能量分辨本領和離子所帶能量的高低。The relation of tthe ccd sensor imaging resolution and the mtf is gotten. when the mtf of space remote sensing camera is higher and the contrast of object is higher, it can be believed that the resolution of ccd sensor imaging is 1. 6 times of the pixel dimension, in the mean while the mtf decreases 32 %
通過模擬得到了ccd探測器的目標影像的分辨力與ccd像元尺寸的關系,當航天光學遙感相機的mtf較高(模擬中鏡頭的mtf = 1 )且目標為高對比度時,得到ccd探測器的目標影像分辨力是其像元尺寸a的1 . 6倍,其光學調制度傳遞函數mtf下降32的結果。Ct method uses array linear detectors to perform high - resolution tomography and yield relative image of linear attenuation coefficient
測出的線衰減系數是相對的,成像要求高分辨。 tgs裝置用的是同軸大體積hpge探測器。In this paper, two novel algorithms of reconstructing high resolution images from both overlapped parallel projection data and overlapped fan beam projection data with low resolution are presented. one is called virtual detector algorithm, and the other is direct reconstruction algorithm. both of the algorithms with two forms for the parallel data and fan beam data respectively are developed based on the interpolative algebraic reconstruction techniques ( iart )
本文在研究插值代數重建法( iart )的基礎上,根據特別設計的數據採集模式(平行相疊采樣和扇形相疊采樣) ,提出了由相疊低分辨數據重建高分辨圖像的兩個新演算法,即虛擬探測器法和直接重建法。The simulation results show that, either for parallel geometry or for fan beam geometry, high resolution images can be reconstructed by means of both the algorithms from the overlapped projection data. moreover, the quality of the images reconstructed by the virtual detector algorithm from the overlapped low - resolution projection data is almost as good as that of the images reconstructed directly from the high - resolution projection data
大量模擬試驗結果表明,無論對平行束的相疊低分辨數據還是對扇形束的相疊低分辨數據,用虛擬探測器法和直接重建法均可由相疊低分辨數據重建出具有較高解析度的圖像。分享友人
