摘要： Methods and devices for calibrating a radiotherapy system are disclosed. The method includes providing a detection medium that responds to exposure to ionizing radiation, and preparing a calibration dose response pattern by exposing predefined regions of the detection medium to different ionizing radiation dose levels. The method also includes measuring responses of the detection medium in the predefined regions to generate a calibration that relates subsequent responses to ionizing radiation dose. Different dose levels are obtained by differentially shielding portions of the detection medium from the ionizing radiation using, for example, a multi-leaf collimator, a secondary collimator, or an attenuation block. Different dose levels can also be obtained by moving the detection medium between exposures. The disclosed device includes a software routine fixed on a computer-readable medium that is configured to generate a calibration that relates a response of a detection medium to ionizing radiation dose.

摘要： A method and apparatus used to calibrate high-resolution electron microscopes where a single standard provides multiple samples, each having a different atomic structure, permits rapid accurate calibration of the entire range of magnifications. The different atomic structure dimensions possess known reference measurement data. The S/TEM is adjusted to focus onto the crystal lattice structure of each sample in a selected sequence. Measurements of these lattice spacings are compared to known dimensions. If S/TEM measurements do not agree with the lattice spacing dimensions, the S/TEM magnification is adjusted to reflect known dimensions. Typical standard exchange and associated processing steps are eliminated by the use of the single standard comprising of a plurality of samples.

摘要： A method for developing a set of gain correction coefficients corrected for structural noise to be used in correcting the digital values representing an image captured by a pixelated detector having a plurality of individual sensors. The gain correction coefficients are developed by first obtaining a first set gain correction coefficients using a flat exposure and adjusting the individual sensor gain output so that all sensors produce the same output value, and then applying a smoothing filter to the first set of gain correction coefficients to obtain a new set of corrected gain correction coefficients.

摘要： The invention relates to a method for adjusting a micro-bar of an electron microscope to increase the accuracy of the micro-bar. The method entails first forming a photo-resist layer on a semiconductor wafer, and exposing a predetermined region of the photo-resist layer to a light of a specific wavelength. Then, a resist stripping process is performed to remove the photo-resist layer in the predetermined region. The periphery of the predetermined region of the photo-resist layer will form a vertical side wall with a periodic wave shape similar to a sine wave, and the wavelength of the periodic wave shape is determined by the wavelength of the light and the refraction rate of the photo-resist layer. Finally, the micro-bar of the electron microscope is adjusted using the wavelength of the periodic wave shape on the vertical side wall.

摘要： Method for correcting an angle error of an absolute-angle detector that detects the angular position of a first shaft whose rotary movement is linked to a second shaft. The angular position of second shaft is first detected during at least one complete revolution of first shaft; the corresponding angular position of first shaft is derived from this value; the corresponding output value of absolute-angle detector is compared to the corresponding angular position of first shaft, and the difference formed by this comparison is stored. The corresponding output value of absolute-angle detector is then corrected by the stored value.

摘要： Automated measurement of changes in detective quantum efficiency (DQE) within an x-ray detector. The calculation of relative DQE changes is limited to the measurement of two quantities, namely MTF(f) and NPS(f). The measurement of MTF is obtained using an image quality phantom technique. The measurement of NPS includes the use of a flat field phantom, and data can be obtained during system calibration. Detector degradation and potential field replacement, are determined by monitoring the ratio of DQE as a function of time.
