WebOrgan-specific PET scanners have been developed to provide both high spatial resolution and sensitivity, although the deployment of several dedicated PET scanners at the same center is costly and space-consuming. Active-PET is a multifunctional PET WebThe resolution of a HPGe detector can be determined by the full width half maximum of the peak. The full width half maximum (FWHM) is defined as the width of the distribution at a level that is just half the maximum ordinate of the peak. The full width tenth maximum (FWTM) is defined as the width of the distribution at a level that is 1/10 the ...

WebThe FWTM is of the order of 0.001. But most of the function's Fourier transform comes from the $\exp(-x^2)/4$ bit. In the Fourier space, the FWHM will be of the order of 1. So we get an uncertainty product of 0.001. You can use this kind of example to show that, with measures like the FWHM, FWTM, you can achieve arbitrarily small uncertainty ... mercury shipping management ltdWebEnter the email address you signed up with and we'll email you a reset link. how old is marcus harrisWebDec 20, 2024 · Figure 4 shows the results of FWHM and FWTM for both CT scanners as a function of R and HP. For the 16-row CT, the FWHM/FWTM at an HP of 0.562 could not be measured because of the wavy shape in the TSP, as shown in Fig. 5.
