WebmeasurePSF. This repository contains the following MATLAB tools that are designed to work with ScanImage. recordPSF to acquire PSF stacks. measurePSF to estimate PSF size. For a demo, run measurePSF ('demo'). Grid2MicsPerPixel measures the number of microns per pixel along x and y by analyzing an image of an EM grid. WebApr 11, 2024 · It should be noted that the PSF for the speckle tracked case noticeably improved from even the applied motion case. ... The FWHM improved from 1.47 to 0.59 mm, 1.76 to 0.83 mm, 1.73 to 0.67 mm and 1.94 to 1.39 mm, respectively. The control case had the point target at a smaller depth due to the lack of tissue layer and was expected to ...

WebThe radial FWHM for PSF was 30-50 % lower than that of OSEM at the center of the FOV. The accuracy of PSF correction was independent of detector design. Quantitative values … WebNov 15, 2014 · We computed HWHM to evaluate the improved resolution of asymmetrically apodized optical system, dealing with PSF with non-zero minima. We obtained FWHM … The point spread function (PSF) describes the response of a focused optical imaging system to a point source or point object. A more general term for the PSF is the system's impulse response; the PSF is the impulse response or impulse response function (IRF) of a focused optical imaging system. The PSF in many contexts can be thought of as the extended blob in an image that represents a single point object, that is considered as a spatial impulse. In functional terms, it is … shiny gym
