摘要： An apparatus for correcting patient motion between views in a medical imaging device employing multiple views in the generation of an image, and where some view data is truncated as a result of the finite area of the detector array, establishes a last row in the matrix of data for each view prior to and independent of the truncation for the purposes of evaluating motion. The data prior to this last row is compared with the data from the previous view with repeated relative shifts between the data to determine a lowest difference sum. Several difference sums may be employed to determine a shifting amount including a fractional part of a row.

摘要： An imaging system of a type producing a plurality of X-Y matrices representing projection views of an object for later reconstruction using parts of a plurality of the views employs correlation techniques for determining the amount of motion along X and Y axes. The detected motion may be removed by suitably shifting later data to align it with earlier data, or vice versa. In one embodiment, all brightness values parallel to the X axes of two views are summed to develop two one-dimensional arrays containing information about the brightness patterns in the Y direction. One of the two one-dimensional arrays is shifted, and the two one-dimensional arrays multiplied, pixel-by-pixel, and the products are summed to provide a measure of similarity between the brightness patterns in the one-dimensional arrays. Repeated shifts produce a correlation function the shift position of whose maximum is a good approximation of the amount of motion occurring between the two views. The detected motion may be used to alert the operator that the data is faulty or to permit automatic alignment of all data from a scan. An identical process may be performed along the Y axis to detect and correct motion along the X axis, in certain restricted cases.
摘要翻译：产生多个X-Y矩阵的成像系统使用用于确定沿着X和Y轴的运动量的相关技术的代表用于稍后重建的物体的投影视图的多个X-Y矩阵。检测到的运动可以通过适当地移动稍后的数据以将其与较早的数据对准，或反之亦然地去除。在一个实施例中，将平行于两个视图的X轴的所有亮度值相加，以形成包含关于Y方向上的亮度图案的信息的两个一维阵列。两个一维阵列中的一个被移动，并且两个一维阵列逐个像素相乘，并且将乘积相加以提供一维阵列中的亮度图案之间的相似度的度量。重复移位产生相关函数，其最大值的偏移位置是在两个视图之间发生的运动量的良好近似。检测到的运动可以用于警告操作者数据有故障或允许扫描所有数据的自动对准。在某些有限的情况下，可以沿Y轴执行相同的过程以检测和校正沿着X轴的运动。

摘要： The invention is a filter apparatus and method for separating suspended solids from fluids, particularly liquids. A filter chamber is defined inside a filter housing. Inside the chamber is a filter bundle, consisting of two or more filter screens, of a non-woven construction. Spaces between the filter screen strands provide channels for fluid to flow through the filter bundle along a tortuous path that is parallel to each screen. These spaces also define openings for directing a flushing fluid, such as air, in a crosswise direction through the filter screens. The crossflow path of the flushing fluid removes solid particles trapped in the channels of the filter screens.

摘要： The specification discloses a method and apparatus for determining the gel time of thermoset resins by using a disposable vial, a disposable spindle for insertion into the vial, a locking collar releasably secured to the disposable vial for mounting the vial in a permanent sample cup and holding it against rotation with respect thereto, and a spindle adaptor releasably receiving the disposable spindle for mounting same to the spindle mount of a conventional viscometer. The thermoset resin is located in the disposable vial along with the disposable spindle. The permanent sample cup including the disposable vial and its contents is located in a heater and the spindle adaptor is secured to the spindle mount of the viscometer. The viscometer is operated and the gel time is determined as the length of time it takes until the viscosity of the heated resin sample begins to increase sharply.

摘要： A nuclear imaging tomographic scanner acquires data from a volume of interest and a tomographic reconstruction is used to produce a three-dimensional array of data elements. A three-dimensional image of an object within this volume of interest as viewed from a projection plane is created using this three-dimensional array of data. The resulting two-dimensional data is shaded by determining the distance between the projection plane and points on the surface of the object. The exact distance is determined using an interpolation method and more distant points are shaded darker. The shading is further accentuated by measuring the gradient of the object's surface and shading points on the surface with a higher gradient darker.

摘要： A grid gates a stream of ions when a D.C. potential is applied between two sets of interdigitated wires included in the grid to produce a D.C. field. The improved grid disclosed herein contains the two sets of interdigitated wires in a single plane so that the D.C. field is precisely normal to the ion current flow direction to prevent a residual ion current flow when the grid provides the gating effect.
