2. Cone beam computed tomography - Wikipedia

   en.wikipedia.org/wiki/Cone_beam_computed_tomography

   Cone beam computed tomography (or CBCT, also referred to as C-arm CT, cone beam volume CT, flat panel CT or Digital Volume Tomography (DVT)) is a medical imaging technique consisting of X-ray computed tomography where the X-rays are divergent, forming a cone.

3. Cone-beam spiral computed tomography - Wikipedia

   en.wikipedia.org/wiki/Cone-beam_spiral_computed...

   Cone-beam spiral computed tomography (CT) is a medical imaging technology that has impacted healthcare since its development in the early 1990s. [1] [2] This technology offers advancements over traditional fan-beam CT, including faster scanning speed, higher image quality, and the ability to generate true three-dimensional volumes, even with contrast-enhancement.

4. Operation of computed tomography - Wikipedia

   en.wikipedia.org/wiki/Operation_of_computed...

   Helical (or spiral) cone beam computed tomography is a type of three-dimensional computed tomography (CT) in which the source (usually of X-rays) describes a helical trajectory relative to the object while a two-dimensional array of detectors measures the transmitted radiation on part of a cone of rays emanating from the source.

5. Image-guided radiation therapy - Wikipedia

   en.wikipedia.org/wiki/Image-guided_radiation_therapy

   Cone-beam computed tomography (CBCT) based image guided systems have been integrated with medical linear accelerators to great success. With improvements in flat-panel technology, CBCT has been able to provide volumetric imaging, and allows for radiographic or fluoroscopic monitoring throughout the treatment process.

6. Tomographic reconstruction - Wikipedia

   Most of the commercial software packages that are available for purchase focus on processing data for benchtop cone-beam CT systems. A few of these software packages include Volume Graphics, InstaRecon, iTomography, Livermore Tomography Tools (LTT), and Cone Beam Software Tools (CST).

7. Cone beam reconstruction - Wikipedia

   en.wikipedia.org/wiki/Cone_beam_reconstruction

   In microtomography X-ray scanners, cone beam reconstruction is one of two common scanning methods, the other being Fan beam reconstruction. [1] Cone beam set-up. Cone beam reconstruction uses a 2-dimensional approach for obtaining projection data. Instead of utilizing a single row of detectors, as fan beam methods do, a cone beam systems uses a ...

   A man has been found guilty of murdering an 86-year-old widow and trying to set her on fire. The body of Una Crown was found at her bungalow on Magazine Lane in Wisbech, Cambridgeshire, on 13 ...

9. Dental radiography - Wikipedia

   en.wikipedia.org/wiki/Dental_radiography

   Cone beam computed tomography (CBCT), also known as digital volume tomography (DVT), is a special type of X-ray technology that generates 3D images. In the recent years, CBCT has been developed specifically for its use in the dental and maxillofacial areas [4] to overcome the limitations of 2D imaging such as buccolingual superimposition. [25]
