At the end of September 2014, the company had around 357,000 employees worldwide. Further information is available on the Internet. Hologic has announced english us food and Drug Administration approval of its new c-view 2D imaging software. C-view 2D images may now be used in place of the conventional 2D exposure previously required as part of a hologic 3D mammography (breast tomosynthesis) screening exam. C-view images are generated from the 3D tomosynthesis data acquired during the mammography exam, eliminating the need for additional 2D exposures. The combination of Hologic's 3D and c-view 2D images results in less time under compression, for greater patient comfort and a lower radiation dose, while still providing the 2D images required as part of Hologic's fda approved 3D mammography screening exam. Clinical studies have shown that screening with Hologic's 3D mammography technology using c-view imaging results in clinical performance superior to that of a conventional 2D mammogram. Peter Soltani, hologic Senior Vice President and General Manager, Breast health, said: "c-view software was developed to provide yet another option to imaging centres to improve patient care and clinical outcomes. Large-scale clinical studies have shown that screening with Hologic's 3D mammography technology allows radiologists to visualise the breast in greater detail than with 2D mammography alone, which results in earlier detection of cancers while at the same time reducing the false positives associated with conventional. Hologic's 3D mammography technology has been approved for use in countries recognising the ce mark since 2008.

Conventional analog mammography and full-field digital mammography display only the 3D structure of the breast on a 2D level, hampering physicians efforts to identify certain types of tumors since anatomical structures in the breast can overlap and obscure lesions. Tomosynthesis acquires several breast projections from different angles and uses raw data to generate a 3d volume set. Using this data set, clinicians can better analyze the type and size of breast lesions as well as microcalcifications compared to other forms of mammography. Breast tomosynthesis increases mammographys sensitivity and specificity, in addition to improving efforts to differentiate and classify breast tumors. Our clinical data has demonstrated that the addition of siemens digital breast tomosynthesis to a patients traditional 2D digital mammogram increases detection of breast tumors. We know that in clinical practice, this increased diagnostic accuracy also means fewer diagnostic biopsy procedures and fewer anxiety-inducing recalls, which typically contributes to both improved patient outcomes and reduced cost, says Gregory sorensen, md, president and ceo of siemens healthcare north America. With the fda approval of the mammomat inspiration with Tomosynthesis Option, siemens healthcare reaffirms its longstanding commitment to cutting-edge innovation in womens health. The mammomat inspiration with Tomosynthesis Option has been commercially available and used clinically for diagnosis since 2009 in Europe, asia, and south America.

Message : required fields, the food and Drug Administration (FDA) has approved the mammomat inspiration with Tomosynthesis Option the breast tomosynthesis add-on option for siemens healthcares mammomat inspiration digital mammography platform. Siemens breast tomosynthesis algorithm reconstructs multiple 2D images of the breast into an approximation of a english 3D image to enable detection of tumors that are hidden by overlapping breast tissue, enabling more accurate diagnosis than standard 2D digital mammography and reducing the number of false-positive. In a recent study involving 22 readers with a broad range of reading experience, siemens demonstrated that all readers improved their accuracy in detecting and diagnosing cancers when reading digital breast tomosynthesis as an adjunct to full-field digital mammography. In tomosynthesis mode, the x-ray tube of the mammomat inspiration digital mammography system rotates in a circular motion around the breast to acquire an image every two degrees while moving through an angular range of 50 degrees. The resulting 25 projections are reconstructed as three-dimensional (3D) digital breast tomosynthesis (DBT) images.

Evaluation of fractures edit tomosynthesis supermarket 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 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.

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. 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 peers 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.
reconstructed from the same acquisition. However, since fewer projections are needed than ct to perform the reconstruction, radiation exposure and cost 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.
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 paper 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 exposures (e.g., 7-51) than.

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 biography 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. 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.
