CT scanning of transportation containers is performed by generating X-rays at various points at the opposite sides of the containers, detecting the X-rays passing through the containers, and analyzing the data received to determine the presence of contraband. The X-rays are generated by modulating a magnetic field through which a high-energy electron beam passes to deflect the beam successively to different targets positioned around the sides of the container, while the electron beam source remains stationary. The X-rays are detected by an array of cells using X-ray responsive storage phosphor material to emit light which is sent to analyzing and comparing equipment. The targets and detectors and the cargo container are moved relative to one another to scan a selected volume of the container.

Method and apparatus are provided for use with a tomographic imaging device. A test object comprising a plurality of angled ramps may be provided to facilitate evaluating performance of the tomographic imaging device. A method for evaluating performance of a tomographic imaging device includes scanning the test object to produce a tomographic slice image and performing analysis on a waveform profile extracted from the image, to determine spatial performance of the tomographic imaging device. A tomographic imaging device may be provided comprising a scanning device and a data processing unit for performing a method of evaluating performance of the tomographic imaging device.

An X-ray apparatus provides rotationally symmetric, Gaussian-like focal spot distributions. The apparatus may be constituted by an X-ray tube having a glass envelope, a cathode in the form of a filament for providing thermionically emitted electrons and an anode. The anode is of conical shape and can be rotated. The cathode is arranged to be rotated about an axis perpendicular to the plane of the filament and passing through its central point. The apparatus may be constituted by a conventional X-ray tube which is rotatable about an axis coaxial with the central ray of the X-ray field which emerges from the tube. The apparatus may be constituted by a conventional X-ray tube, which is stationary, in combination with a mechanism which effects rotation of the X-ray image receptor and the object being to be examined about an axis coaxial with the central ray of the X-ray field.

A test body is provided for determining an operating characteristic of a tomographic apparatus of the type that scans a human body member with an X-ray beam along an edge of a slice through the member, accumulates data in electrical form which is representative of the variations in the intensity of X-ray transmission through the body during a plurality of scans and reconstructs a cross sectional image of the slice from the accumulated data. The body comprises an energy absorption means which is arranged in a predetermined configuration and is adapted for absorbing electromagnetic energy from an impinging X-ray beam. The body also includes support means for positioning the energy absorbing means between a scanning X-ray beam and a detector of the apparatus.

A radiation phantom comprising a solid opaque housing having an inner chamber is provided within which a test pattern for quantifying image quality, and at least one dosimeter for simultaneously measuring radiation dosage are randomly disposed. A tamper proof means is connected to the opaque housing such that the test pattern and the at least one dosimeter are unviewable and unaccessible within the chamber. Thus, the test pattern and the at least one dosimeter are "interlocked" within the radiation phantom housing such that the radiation phantom can be employed to accurately evaluate off-site a radiation machine's imaging of the radiation phantom without requiring the presence of an independent qualified technician on-site during irradiation of the phantom.

A method for measuring the CT numbers of an in vivo tissues includes the steps of calculating a histogram of a region including the tissue, locating a leading edge of a peak within the histogram, substracting CT numbers assumed to result from background and intermixing of tissues, fitting the background-substracted peak to a gaussian distribution, and calculating the mode of the resulting peak. Whe the CT numbers of two different tissues having know densities are measured according to the method of the invention, the CT numbers may be used to obtain a standard for analyzing tissues of unknow density. The method can be implemented by means of a CT scanner, a computer, and appropriate software.
