Fwhm / fwtm
WebThe amplitude spectrums with different shaping times are created to study the shape of the characteristic peak. The results show that the Step-Gaussian filter can cancel the low-energy peak tailing of the 5.89 keV peak. The peak shape parameter, FWTM/FWHM ratio, is also introduced to evaluate the performance of peak shape improvement. Web0.1 FWHM”, that is _0.3 mm for a 540 mm diameter gamma camera. To achieve the specified “pixel size” the ... (FWTM) for each of a series of profiles drawn across the slit lines. Themean, maximum, and minimum values for the set of profiles are then determined. Linearity assessment requires calculation of the deviation of the

WebApr 5, 2006 · width = fwhm (x,y) Full-Width at Half-Maximum (FWHM) of the waveform y (x) and its polarity. The FWHM result in 'width' will be in units of 'x'. The code was developed by an unknown author. WebMar 31, 2024 · The FWHM is the full width of the beam at half of the maximum intensity, so we need to divide this value by 2 so that we can replace it with r, the radial size. …
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 ... 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

WebMar 1, 2024 · Dear Root users I am new on root and i want to get FWTM for skewed Gaussian. I found the crystal ball function to be a good fit for my histogram which has a tail at low energies. For normal Gaussian, FWHM = 2.35sigma and FWTM= 4.29sigma. However this is not the case for a skewed Gaussian as it has a tail. Is there way to get …
