摘要： In an X-ray scanning system having an X-ray source and an X-ray detector assembly, including a plurality of X-ray detector crystals grouped in substantially linear arrays (34) and cooperative with the X-ray source, a substantially continuous radiation detection zone is established by positioning the detector arrays so that substantially all radiation from the source passing through the detector assembly passes through at least a portion of at least one detector crystal. The detector arrays are tilted at a preselected angle α with respect to a nominally perpendicular orientation relative to radial lines (42) extending from the focal spot, so that the spaces between adjacent detector crystals in an array are not aligned with X-rays emanating from the X-ray source. The angle α is a function of the geometry of the detector crystals and the space between adjacent crystals in an array.

摘要： A method and apparatus (100) for detecting objects (112) in computed tomography (CT) data are disclosed. Sheet-shaped objects such as sheet explosives can be detected by analyzing the density of test voxel and mean density of its neighborhood voxels. Sheet objects can also be detected by performing erosion and dilation operations. A corrected mass using the mean eroded density of the object can be computed and compared to mass thresholds to classify the object as to whether it poses a threat. Bulk objects can be detected by a modified morphological connected component labeling (CCL) approach which performs a series of erosion and dilation steps to separate adjacent objects in the data such that they can be individually labeled and analyzed. The system can also identify objects that contain liquids. The overall system performance, including overall object detection rate and false alarm rate, can be adjusted by adjusting individual object detection rate and/or false alarm rates.

摘要： CT (120) baggage (112) inspection with a throughput on order of 700 bags (112) per hour is achieved by excluding unrelated data from reconstruction. By using a threshold, calibration 'air scans' can be performed with objects such as the system conveyor (110) in the field of view. The scanner identifies object shape to better detect sheet explosives. The system compensated for dark currents and temperature dependent current offsets.

摘要： An apparatus for compensating for drift of the focal spot (42) of an x-ray radiation source (118) used in a tomography system is disclosed so as to maintain a primary collimated beam (70) of radiation emanating from the focal spot aligned with target detectors (50) of the tomography system. A second collimated beam (170) of radiation is produced from the same focal spot and directed along a different axis from the first beam. An array (180) of detectors tracks the movement of the second collimated beam and produces signals which are used to reposition the collimators used to collimate the primary beam so as to maintain the primary beam substantially aligned with the target detectors.

摘要： The present disclosure provides a gantry (14) of a CT scanner. The gantry (14) includes an annular outer support (16) having a radially inwardly facing, continuous circumferential bearing chamber (24), an annular drum (18) concentrically positioned within the outer support (16) and having a continuous circumferential bearing lip (26) radially extending into the bearing chamber (24) of the outer support (16) to define two circumferential bearing runs within the bearing chamber (24), and an annular disk (20) extending radially inwardly from an inner circumferential surface of the drum (18). The disk (20) is adapted to receive and support computed tomography components. The gantry (14) also includes roller bearings (32) in the bearing runs (28, 30) rotatably supporting the drum (18) within the outer support (16), such that the drum (18) and the disk (20) are rotatable about a rotation axis (R) of the drum (18).

摘要： An apparatus and method for identifying and classifying objects represented in computed tomography (CT) (400) data for a region using the shape (402) of the objects are disclosed. An object represented by CT data for a region is identified (404). Next, a two-dimensional projection of the object along a principal axis of the object is generated (415). The principal axis is identified by computing eigenvectors of a covariance matrix of spatial locations of voxels in the CT data that are associated with the object (408). The smallest eigenvector can be selected as the principal axis of the object along which the two-dimensional projection is generated (412). The identification of the object can be used in the classification of the object such as by altering one or more discrimination parameters (416).

摘要： A CT scanner (10) and method are designed to scan a preselected portion of the lower abdomen with higher resolution and lower power. The scanner is constructed with a source (14) and detector array (16) designed to rotate about a rotation axis oriented substantially parallel to or coincident with the hips of the a patient so that X-rays do not have to pass through the pelvic bones to image the area of interest. Higher resolution can be achieved by using a detector array of the type used for digital radiography so that individual detectors can be much smaller than those used in conventional CT machines. A high resolution CT image can thus be used to detect the presence of prostatic cancer, by first injecting the patient with a material including a high contrast material for X-ray imaging and a material for binding the high contrast material to a specific biological site if present in the preselected portion of the lower abdomen of the patient; and generating a CT image of the preselected portion of the lower abdomen of the patient so as to generate an image of the preselected portion of the lower abdomen of the patient so as to image any of said high contrast material.
