8 Musculoskeletal imaging edit tomosynthesis has a much more limited depth of field than does. For this reason, it likely will not be able to replace ct for the evaluation of the deeper organs of the body. However, since bones are often near the skin, multiple musculoskeletal applications of tomosynthesis have been studied, most of which have mostly been used in research with limited use in everyday practice. Evaluation of fractures edit tomosynthesis has been compared to both radiography and ct for the evaluation of healing fractures, especially in the presence of hardware. In a study of patients with wrist fractures, digital tomosynthesis was shown to enable detection of more fractures than radiography while simultaneously providing lower metal artifact than radiography. 4 evaluation of erosions in rheumatoid arthritis edit tomosythesis father's has been compared to radiography, with ct as the standard, for the detection of erosions associated with rheumatoid arthritis. The radiation dose of digital tomosynthesis was very close to that of radiography.
2016 however it is unclear if its use in screening normal risk women is beneficial or harmful. 6 Digital breast tomosynthesis (DBT) can provide a higher diagnostic accuracy compared to conventional mammography. In dbt, like conventional mammography, compression is used to improve image quality and decreases radiation dose. The laminographic imaging technique dates to the 1930s and belongs to the category of geometric or linear tomography. 7 Because the data acquired are micron typical resolution, much higher than ct, dbt is unable to offer the narrow slice widths that ct offers (typically 1-1.5 mm). However, the higher resolution detectors permit very high in-plane resolution, even if the z-axis resolution is less. The primary interest in dbt is in breast imaging, as an extension to mammography, where it offers better detection rates with little extra increase in radiation.
Some manufacturers have produced practical systems using off-the-shelf. Gpus to perform the reconstruction in a few seconds. Differences from other imaging modalities edit, digital tomosynthesis combines digital image capture and processing with friend simple tube/detector motion as used in conventional computed tomography (CT). However, though there are some similarities to ct, it is a separate technique. In ct, the source/detector makes at least a complete 180-degree rotation about the subject obtaining a complete set of data from which images may be reconstructed. Digital tomosynthesis, on the other hand, only uses a limited rotation angle (e.g., 15-60 degrees) with a lower number of discrete exposures (e.g., 7-51) than. This incomplete set of projections is digitally processed to yield images similar to conventional tomography with a limited depth of field. Because the image processing is digital, a series of slices at different depths and with different thicknesses can be reconstructed from the same acquisition.

Tomosynthesis, also digital tomosynthesis, is a method for performing high-resolution limited-angle tomography at radiation dose levels comparable with projectional radiography. It has been studied for a variety of clinical applications, including vascular imaging, dental imaging, orthopedic imaging, mammographic imaging, musculoskeletal imaging, and chest imaging. 1, contents, history edit, the concept of tomosynthesis was derived from the work of ziedses des Plantes, who developed methods of reconstructing an arbitrary number of planes from a set of projections. Though this idea was displaced by the advent of computed tomography, tomosynthesis later gained interest as a low-dose tomographic alternative. 2, reconstruction edit, tomosythesis reconstruction algorithms are similar to ct reconstructions, in that they are based shredder on performing an inverse. Due to partial data sampling with very few projections, approximation algorithms have to be used. Filtered back projection and iterative, expectation-maximization algorithms have both been used to reconstruct the data. 3, reconstruction algorithms for tomosynthesis are different from those of conventional ct because the conventional filtered back projection algorithm requires a complete set of data. Iterative algorithms based upon expectation maximization are most commonly used, but are computationally intensive.
