An Operational Model for Microchannel Plate Devices

IEEE Transactions on Nuclear Science, 1981

The behavior of optical detectors using microchannel plates (MCPs) as electron multipliers is described in terms of the physical parameters of the MCP (channel resistance, channel capacitance, channel wall secondary emission ratio, etc.).

  • A fast Maximum Likelihood method for improving AMCW lidar precision using waveform shape

    Amplitude Modulated Continuous Wave imaging lidar systems use the time-of- flight principle to determine the range to objects in a scene. Typical systems use modulated illumination of a scene and a modulated sensor or image intensifier. By changing the relative phase of the two modulation signals it is possible to measure the phase shift induced in the illumination signal, thus the range to the scene. In practical systems, the resultant correlation waveform contains harmonics that typically result in a non-linear range response. Nevertheless, these harmonics can be used to improve range precision. We model a waveform continuously variable in phase and intensity as a linear interpolation. By approximating the problem as a Maximum Likelihood problem, an analytic solution for the problem is derived that enables an entire range image to be processed in a few seconds. A substantial improvement in overall RMS error and precision over the standard Fourier phase analysis approach results.

  • Optical observation of 3D streamer image in resistive plate counter

    3D streamer image in a resistive plate counter (RPC) were taken by using a glass RPC, an image intensifier and a CCD camera. Observations were simultaneously made for self-discharge in top and side view, operated in the streamer mode with various gas mixtures(Ar/butane/HFC134a). The analysis of the streamer image might be useful for us to design the pickup strip width for the readout. We report on a shape of the streamer in the top and side view as a function of gas mixing ratio.

  • Acceptance testing and commissioning of a Ximatron radiotherapy simulator

    Though it is well understood that the success of radiotherapy involves correct treatment simulation and accurate patient positioning, the quality assurance of the radiotherapy simulator receives little attention. A radiotherapy simulator combines the technology from therapeutic and diagnostic radiology and needs to be tested for both. As pre-commissioning quality assurance program, the Varian Ximatron simulator was checked for (i) mechanical and optical parameters; (ii) parameters of X-ray beam; (iii) performance of image intensifier; and (iv) parameters relating to safety and radiation protection. In this paper the authors present the methods adopted and the results of the quality assurance of the Ximatron radiotherapy simulator.

  • Improvement of continuous position sensitive diode performances and associated electronics

    In contrast to position segmented detectors, continuous Position Sensitive Detectors (whose localisation is based on current division) remain of interest when count rate is not critical. That is the case with several imaging applications in nuclear medicine and biology. Continuous PSDs offer large detection areas (up to 60/spl times/60 mm/sup 2/) and a spatial resolution inversely proportional to the energy deposited. Therefore, when coupled to an image intensifier tube, their spatial performances are suited to g medical diagnosis. After a brief presentation of the /spl gamma/ compact camera developed and dedicated to localised the sentinel lymph-node; we recall briefly the principle of the 3 kinds of PSD. Then, we describe a simulation model developed using CAO AWB/Cadence which taking into account both detector and readout electronics. In our application, a duo lateral photodiode filtered with a trapezoidal spectroscopy amplifier achieves the best compromise between linearity and spatial resolution. Because a signal deficit appears when PSD is coupled to a classical charge preamplifier, an impedance adaptation which improves detection performances is presented.

  • Whole-field fluorescence lifetime imaging with picosecond resolution using ultrafast 10-kHz solid-state amplifier technology

    We report the development of a high temporal resolution whole-field fluorescence lifetime imaging system based on an ultrafast solid-state laser system and a time-gated image intensifier operating at up to 10 kHz. The temporal instrument response is /spl sim/110 ps and we have imaged (environmentally perturbed) differences in fluorescence lifetime as small as 20 ps. Fluorophores exhibiting single- or double-exponential fluorescence decay profiles are routinely imaged and a near real-time update time of 3 s for the fluorescence lifetime map has been demonstrated using a modest personal computer. We also present provisional fluorescence lifetime images of tissue constituents. This fluorescence lifetime imaging technology is applicable to almost any optical instrument configuration and, when coupled with existing all-solid-state diode-pumped ultrafast laser technology, may yield a potentially inexpensive instrument for in vitro and in vivo biomedical imaging.

  • The accuracy and reproducibility of an algorithm to correct for geometric image distortion in quantitative coronary angiography

    The authors have developed a method to correct for image distortion (so-called dewarp). The method models the distortion by a set of two-dimensional polynomials of which the degree is optimally adjusted. The model parameters are derived through imaging a cm-grid put against the image intensifier (II) input screen. The derived accuracy of the pixel size (scale factor) was better than 0.006% and the RMS length of the residuals was 0.03-0.05 mm for cine film and 0.04-0.09 mm for on-line video images. The reproducibility for a dewarped position was 0.01-0.04 mm for cine film and 0.04-0.07 mm for video images, depending on the II size (14/17/27 cm). The dewarped size of an object (vessel) reproduced between 0.04% and 0.11% for cine film and between 0.15% and 0.18% for video images, depending on the II size. The main source of variability turned out to be an unstable high-voltage of the electron optics in the II.
