For various applications, the entire work piece geometry must be dimensionally analyzed. To document the quality of a mold for plastic injection molded parts, for example, a sample part must be measured completely (first article inspection). Particularly for medical component […]

Analysis of the tomography results generally starts with a comparison of CAD data to the point cloud position and orientation (work piece coordinate system) and subsequent overlaying of both. Various methods are available for this. One method consists of constructing […]

The radiation spectrum can also be optimized with the use of filters, made of aluminum, tin, or gold, at the output window of the X-ray tube.  The  use  of  such filters,  however, results in lower radiation intensities, which must be […]

The voltage changes the frequency spectrum of the radiation at the same time, and must therefore be optimized for the material of the measurement object. Different materials and voltage levels result in different maximum radiographic lengths. These must be considered […]

  The hazardous health effects of X-rays must be considered when using this radiation for measurements.  Coordinate measuring machines with X-ray tomography that meet the requirements for fully protected machines under the X-ray regulations have lead shielding in the machine […]

For measuring machines with a precision of a few micrometers, the linear axes can have mechanical bearings.  For higher precision requirements, in the sub-micro- meter range, air bearings are used due to the better repeatability. As is typical for coordinate […]

Various sensors can then be selected from the palette of multisensor coordinate measuring machines and used with this interface.  Figure shows such a tilting joint with an image processing measurement head. This measurement head can optionally be equipped with a […]

To hold the magnification constant when changing the distance between the source and sensor, the rotary axis must be shifted accordingly in the direction of the sensor. The increased cone angle can cause measurement errors in the lower and upper […]

If a measuring machine is not designed specifically for a dedicated application, but is intended to have flexibility, linear axes are needed in addition to the rotary axis. They serve to adjust the magnification to position the work piece and […]

The image scale between the object plane and the sensor (usually, but not entirely accurately, referred to as the magnification) is in principle greater for large sensors with large pixels, because a greater distance is needed to form an image […]

Industrial X-ray tomography machines typically use area sensors with a scintillator. The scintillator converts the X-rays that strike the sensor into light. The high-energy photons of the X-rays excite particles of the scintillator material as they pass through it. These […]

The smaller the cone angle, the lower these measurement errors. This means that it makes sense to design high precision machines with a greater distance between the X-ray source and the sensor. However, this reduces the efficiency of the X-ray […]

X-ray sensors are available both as line sensors and area sensors. From a purely geometric standpoint, line sensors would be perfect. Synchronized movement of the X-ray source and the line sensor relative to the measured object in the direction of […]

The construction of an X-ray tube is very complex in detail. In addition to the electrodes and the target, it has a large number of components for focusing the beam, electrode heating, and other functions.  Due to the required   measurement […]

The targets of X-ray tubes are fundamentally classified as reflection targets and transmission targets. The difference when using reflection or transmission targets is in the available radiation power, and therefore the measurement time in conjunction with the available minimum focal […]

The tubes used to generate X-rays are a core component of X-ray tomography machines. They operate on the basic principle of electron beam tubes. Free electrons are generated in a vacuum by thermionic emission, and accelerated by an electrical field […]

If the diameter of the enveloping circle of the measured object is larger than the sensor size in the work piece plane (e. g. disc shaped parts), the rastering must be done perpendicular to the rotary axis. For compact measured objects, […]

This figure shows an example of rastering along the rotary axis. However, this can be used only for relatively slim objects, such as long connectors. In this example, without raster tomography a voxel size of 0.25 mm is achieved with […]

The resolution of the entire image is increased by capturing several partial images. This can lead to a significantly greater quantity of available data. If raster tomography is used only for expanding the measurement range for measuring larger parts, this […]

The method described above, wherein the entire object is captured in one image, can also be referred to as tomography “in the image”, as in image processing.  At times, the entire measured object cannot be captured in one image. The […]

Another application for raster tomography is to increase spatial resolution, if the sensor does not have sufficient resolution to measure small details of larger work pieces “in the picture”.  In this case, the appropriate magnification level is selected to achieve […]

If the neighbor points of a given measurement point are required for further processing, they are identified directly by the triangle definition. No time-consuming search algorithms are needed. If the entire amount of object information is not required, the calculation […]

Alternatively, the edge locations can be derived from the local maximum of the differentiated volumes, or by means of integral edge definitions.  These methods have a significant effect on the precision of the entire system.   These calculation steps can readily […]

The volume information thus derived can be used for an initial visual inspection for cavities, inclusions, or other internal structures.  In order to derive dimensions from this data, the precise location of the material borders or transitions (e.g. from metal […]

After filtering, the existing projection images are reverse-projected (commonly known as back projection).  The back projection of the 2D X-ray images can be imagined as though the procedure for generating the projection images using the measuring machine is mathematically reversed […]

Filtering, to increase the intensity of the edges,  is  done  through  the  convolution  of the image with a filtering function. This can be imagined as similar to sharpening the focus of a digital photo by using image processing software.    […]

Volume data can be calculated from the two- dimensional radiographic images.  This   is analogous   to   the   pixel   (picture   element) which 2D image processing sensors use to represent the local light intensity of the image in an equidistant, planar array.  The […]

By shifting the rotary axis and the measured object relative to the X-ray unit (source and sensor), the magnification can be adjusted for work piece size and tolerances.   In this manner, small objects or segments of objects can be measured […]

Prior to tomography of a work piece, the right imaging scale (magnification) must be selected for the measuring machine. The desired detail resolution must be considered. It must also be ensured that the desired area of the work piece, or […]

X-ray tomography uses the ability of X-ray radiation to penetrate objects. An X-ray tube can be considered almost a point source of X- rays. The X-rays pass through the measured object to reach the X-ray sensor. On the way through […]

X-ray tomography, also known as computed tomography (CT), can be used to completely capture spatially extensive objects, including their internal structures for metrology purposes.
