Digital x-ray tomosynthesis is a technique for producing slice images using conventional x-ray systems it is a refinement of conventional geometric tomography, which has been known since the 1930s. 2 welcome from program directors welcome to duke university and the tomosynthesis symposium 2009 we are delighted that.
Digital breast tomosynthesis (dbt) is a three-dimensional imaging technique providing an arbitrary set of reconstruction planes in the breast with limited series of projection images a framework for optimising the radiographic technique in digital x-ray imaging.
Duke uses 3-d mammograms (digital breast tomosynthesis) to screen for breast cancer because of its proven record of detecting more and smaller breast cancers and reducing the number of false alarms we rely on traditional 2-d digital mammography to more closely examine some abnormalities identified at screening. Duke radiology is one of the largest providers of continuing medical education (cme) nationally, and the breast imaging division is an important part of these efforts. Digital breast tomosynthesis (3-d mammography), available at duke locations in durham and raleigh, is the latest diagnostic advance in breast cancer detection jay baker, md, a duke radiologist, explains what it is, and how 3-d mammography differs from traditional digital mammography. • digital tomosynthesis is a process used to reconstruct 3-d images of from 2-d scans • advantages of dts include comfort, speed, and lower radiation dosage • it may eventually replace conventional mammography as it become less expensive • currently, it is only approved in the eu.
The duke radiology difference matters clinical expertise: your mammogram is always interpreted by a physician who is fellowship-trained in breast imaging every time you have your mammogram done at duke cancer institute’s breast center, patterson place and southpoint locations only these three sites in the triangle can guarantee this kind of expertise.
Tomosynthesis is a technique in which several low dose x-ray images of the breast are obtained at various angles, and thin tomographic slices of the breast are reconstructed this technique removes the problem of overlapping breast tissue, making detection of breast lesions easier, and, in theory, improving the sensitivity of mammography. Technology an imaging system for performing tomosynthesis on a region of an object comprises an x-ray source, motion controller, an x-ray detector and a processing unit the x-ray source is positioned at a predetermined distance from the object and continuously moves along a linear path relative to the object. Finally, the faculty and staff of duke breast imaging are strongly committed to improving the quality of breast imaging practice more broadly through educational activities duke radiology is one of the largest providers of continuing medical education (cme) nationally, and the breast imaging division is an important part of these efforts.
Digital tomosynthesis is a radiographic technique that can produce an arbitrary number of section images of a patient from a single pass of the x-ray tube it utilizes a conventional x-ray tube, a flat-panel detector, a computer-controlled tube mover, and special reconstruction algorithms to produce.
