Introduction digital tomosynthesis is a newly available imaging modality that offers the potential to be a substantial improvement over conventional chest radiography for the detection of subtle lung disease. Digital tomosynthesis is a relatively novel imaging modality using limited angle tomography to provide 3d imaging the purpose of this review is to compare the sensitivity of digital tomosynthesis of the chest and plain film chest imaging in accurately identifying pulmonary nodules and to compare the effective dose between standard chest examinations using digital tomosynthesis and ct. Digital tomosynthesis of the breast is different from a standard mammogram in the same way a ct scan of the chest is different from a standard chest x-ray or think of the difference between a ball and a circle.

New research shows that digital tomosynthesis (dt) significantly outperforms chest radiography in the detection of potentially malignant lung nodules, while also improving decisions about patient management and with a lower radiation dose than ct, a possible role for this technology in lung cancer .

Digital tomosynthesis is a newly available imaging modality that offers the potential to be a substantial improvement over conventional chest radiography for the detection of subtle lung dis-. Digital tomosynthesis is a technique that generates an arbitrary number of section images of a patient from a single pass of the x-ray tube it is under investigation for application to a number of clinical detection tasks, and has recently been implemented in commercial devices for chest . •digital tomosynthesis (dt) has a lower cost and lower effective radiation dose of about 01 msv (30-70 times lower than that for multidetector ct, comparable to the dose of a posteroanterior and lateral chest radiographs) [4, 5, 6]. Digital tomosynthesis (dt) refers to the technique of collecting a number of projection radiographs at very low doses (lds) and at varying angles, using these radiographs.

Digital breast tomosynthesis (dbt) is an imaging technique that allows a volumetric reconstruction of the whole breast from a finite number of low-dose two-dimensional projections obtained by different x-ray tube angles, with a geometric principl. Dual-energy subtraction digital tomosynthesis with pulsed x-ray and rapid kv switching was used to examine calcifications in pulmonary lesions the digital tomosynthesis system used included a conventional fluororadiographic tv unit with linear tomographic capabilities, a high resolution videocamera . Digital tomosynthesis (dts) of the chest is a technique whose basic components are similar to those of digital radiography, but that also provides some of the benefts of computed tomography (ct).
