Transmission and Emission Tomography,he injected isotopes within the patient. Even for emission scans, an additional transmission scan is sometimes required in order to compensate for the attenuation effect of the emission photons. Some attenuation compensation methods for emission imaging are discussed in this chapter.作者: 圓錐 時間: 2025-3-24 06:42 作者: Psa617 時間: 2025-3-24 13:47 作者: Opponent 時間: 2025-3-24 17:23 作者: RAG 時間: 2025-3-24 22:23

Parallel-Beam Image Reconstruction,he Fourier domain. From this theorem, many image reconstruction algorithms are derived. Among these algorithms, the filtered backprojection (FBP) algorithm is the most popular one, which consists of a ramp-filtering step and a backprojection step. The filtering can be implemented as a multiplication作者: GEAR 時間: 2025-3-26 15:27
Fan-Beam Image Reconstruction,not along parallel lines, the image reconstruction algorithms presented in Chapter 2 cannot be applied directly.

Transmission and Emission Tomography,a. If the radiation sources are inside the patient, the imaging system acquires the emission data. For transmission scans, the image to be obtained is a map (or distribution) of the attenuation coefficients inside the patient. For the emission scans, the image to be obtained is the distribution of t作者: Toxoid-Vaccines 時間: 2025-3-26 23:10

For the 3D parallel lineintegral projections and parallel plane-integral projections, there exist the central slice theorems, from which the image reconstruction algorithms can be derived.
