Investigation of the Spatial Resolution of MR-Based Polymer Gel Dosimetry versus Film Densitometry using Dose Modulation Transfer Function
Introduction: The conventional methods of dosimetry are not capable of dosimetry in such a small volume of less than one cubic millimeter. Although the polymer gel dosimetry method based on magnetic resonance imaging (MRI) could achieve three dimensional dosimetry with high resolution, a spatial resolution evaluation based on gel dose modulation transfer function has not been investigated yet. ...
متن کاملAutomatic Interior Orientation of Kfa-1000 Space Photo
This paper concerned with a comparative study and implementation of Interior orientation manually and automatically for KFA1000. In manually method, firstly, we reproduced the image to its reduced size photographically from the original image to be measurable in a mono comparator from 30*30 cm to 23*23 cm which proceeds by measuring of photo coordinates of four pieces of KFA-1000 photo. After c...
متن کاملتحلیلی مقدماتی از کاربرد تصاویر ماهواره ای COSMOS (KFA-1000) در طرح های توسعه
یافته های موجود در هئیت فعلی خود نه بر پایه یافته های حاصل از آزمایشات متعدد و کسب تجربه ای طولانی و لازم بلکه بیشتر بر پایه تجربه و قضاوت و برداشت اینجانب در طول تهیه طرح های جامع شهرستانهای میانه، میاندوآب، مسجد سلیمان و اردبیل تدوین گردیده است. بنابراین امید است به تدریج با داده های فنی بیشتر توسط صاحب نظران فن تکمیل گردد. زیرا به جرأت می توان اذعان داشت که اطلاعات واصله از ماهواره ه...
متن کاملModulation Transfer Function Measurement Method and Results for the Orbview-3 High Resolution Imaging Satellite
The Modulation Transfer Function (MTF) is a fundamental imaging system design specification and system quality metric often used in remote sensing. MTF is defined as the normalized magnitude of the Fourier Transform of the imaging system’s point spread function. Alternatively, the MTF describes the attenuation of sinusoidal waveforms as a function of spatial frequency. Practically, MTF is a met...
