1-3 dbt has also demonstrated utility in imaging dense breast tissue, which by nature can be challenging to adequately image and interpret using dm alone given the propensity for tissue overlap. 4 However, the combination of DM/dbt exposes patients to approximately two times the radiation dose of dm alone, although the amount of exposure remains well below fda-defined limits. To address radiation dose concerns, the fda has approved the use of synthesized 2D images (sDM) that are generated from the 3D data set. Synthetic 2D images by definition are produced without the need for the additional radiation required for standard dm images. 4 Recent studies have found that sDM/dbt performed similarly to dm/dbt, concluding that sDM may eliminate the need for dm as part of a routine clinical study, while reducing radiation dose.

4 evaluation of erosions in rheumatoid arthritis edit tomosythesis has been compared to digital 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 digital radiography. However, tomosynthesis showed sensitivity, specificity, accuracy, positive predictive value, and negative predictive value of 80, 75, 78, 76, and 80, compared to digital radiography were 66, 81, 74, 77, and. 10 The slight benefit digital tomosynthesis in this application may or may not justify the slightly increased cost of the modality compared to digital radiography.

8 Chest edit This section is missing information about Digital tomosynthesis of the chest. Please expand the section to include this information. Further details may exist on the talk page. (July 2018) 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, vbs 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.

are both reduced. 4, applications edit, breast edit, tomosynthesis is, food and Drug Administration (FDA) approved for use in breast cancer screening. Owever 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.

Iterative algorithms based upon expectation maximization are most commonly used, but are computationally intensive. 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 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 modern (helical) 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 about 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.

Tomosynthesis, also digital tomosynthesis dts 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 garden similar. Ct reconstructions, in that they are based 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.
