摘要： A radiographic machine in which the exposure is equalized as between different areas of the image plane so as to enhance high spatial frequency features of the image and suppress low spatial frequency features and achieve other benefits as well. A fan beam (12) which is wide enough to encompass the object (16) being imaged (18) is swept across the object and segments of that beam (23) are individually pulse width modulated at each of a number of sampling intervals during the sweep by monostable or bistable shutter pins (20) which either completely block or completely uncover the sectors which they control (22). An alternate embodiment adds beam width modulation as well, by making the shutter pins either completely block their sectors or uncover them only to the degree necessary for beam width modulation.

摘要： The present disclosure relates to a collimator. The collimator may include a motor, a transmission unit having a first end and a second end, and a leaf unit having a leaf. The first end of the transmission unit may be connected to the motor and the second end of the transmission unit may be connected to the leaf. The present disclosure also relates to a collimator system. The collimator system may include a leaf module having a leaf, a driving module having a motor configured to drive the leaf, and a processing module to generate a movement profile of the leaf. The movement profile of the leaf may include a first speed during a first stage, a second speed of the leaf during a second stage, and a third speed of the leaf during a third stage.

摘要： A method includes determining a first estimate of leaf positions for a plurality of leaves of a multi-leaf collimator (MLC) in a reference coordinate space based on an image generated by an image-based aperture verification system, wherein the leaf positions for the plurality of leaves define an aperture for the MLC. The method further includes determining a second estimate of the leaf positions for the plurality of leaves in the reference coordinate space based on data from an additional source. The method further includes verifying the leaf positions for the plurality of leaves based on comparing the first estimate to the second estimate, wherein the leaf positions are verified if the first estimate deviates from the second estimate by less than a threshold value.

摘要： Apparatus and methods for providing a distance indication using an x-ray apparatus. According to various embodiments, an x-ray apparatus may be provided comprising an x-ray generator and a visible light generator. The apparatus may further comprise a projection member, such as a reticle, comprising a material at least partially transparent to visible light, wherein the projection member comprises an image positioned within the path of the visible light so as to project a secondary image comprising a shadow defined by the image. A LASER configured to deliver a LASER beam at an angle relative to the visible light may be provided such that the LASER beam intersects at least a portion of the secondary image at a predetermined distance from the LASER to allow a user to determine precisely a distance from the apparatus to an object to be exposed to x-ray radiation.
