Quantum noise in X-ray image intensifiers.
نویسنده
چکیده
Explicit expressions are given for the relative variance of the output screen of X-ray image intensifiers, and for detection quantum efficiency as a function of the technical features of the intensifier. The analysis takes into account all conversion stages and physical processes inside the image intensifier and includes a special treatment of scintillation. The results are analysed numerically both for previously reported approximations and for applying this more recent method of detailed visibility calculations.

Optimal calibration marker mesh for 2D X-ray sensors in 3D reconstruction.
Image intensifiers suffer from distortions due to magnetic fields. In order to use this X-ray projections images for computer-assisted medical interventions, image intensifiers need to be calibrated. Opaque markers are often used for the correction of the image distortion and the estimation of the acquisition geometry parameters. Information under the markers is then lost. In this work, we cons...
متن کاملInvestigation of dosimetric characteristic of NIPAM polymer gel using x-ray CT
Introduction: Polymer gel dosimeters contain chemical materials sensitive to the radiation which are polymerized by the radiation as a function of absorbed dose. So information of spatial dose distribution can be extracted by imaging from irradiated gel. Among imaging techniques, computed tomography (CT) poses as an attractive method because of practical advantages such as acce...
متن کاملA novel approach for distortion correction for X-ray image intensifiers.
Applications of X-ray image intensifiers in medical imaging, include the use of fluoroscopic projection images to generate three-dimensional tomographic reconstructions. Unfortunately, the inherent distortions on the acquired projections deteriorate the quality of the reconstructed tomograms. Distortion correction can be performed using algorithms that can be classified as global or local accor...
متن کاملImage Detectors for Digital Image Microscopy
Advances in solid state technologies have led to a range of CCD cameras from inexpensive video cameras to expensive scientific digital camera systems. The best choice (best value for money) depends heavily on the application. A state-of-the-art camera’s performance is limited by two fundamental laws of nature. Spatial resolution is limited by diffraction and noise is limited by quantum physics....
متن کاملAnalysis of the spatial-frequency-dependent DQE of optically coupled digital mammography detectors.
The effect of optical coupling efficiency on the spatial-frequency-dependent propagation of signal and noise is considered for x-ray image detectors for digital mammography in which a phosphor screen is optically coupled to a charge-coupled device (CCD) image array. For experimental purposes, optical coupling between a Gd2O2S:Tb phosphor screen and a CCD image array was provided by relay lenses...
