Cone beam computed tomography (CBCT), is a recent medical imaging technique where the X-rays are divergent, forming a cone.
As a result, this technique is less irradiating that the scanner. The purpose of this exploratory study is to compare the performance of the scanner and the cone beam in the detection of anatomical structures of the ear.

This study is designed to investigate whether daily images of the pelvis and bladder using a device called a cone beam CT scanner will help to increase the accuracy of radiotherapy treatme...
To evaluate the use of cone beam computed tomography in treating head and neck to hopefully reduce side effects
The purpose of this study is to use cone-beam CT scans to more accurately position the tumor during radiation and to see whether this method is more effective than the standard method of u...
The overarching objective of our proposal is to develop a One-Stop-Shop imaging using the available C-arm Cone-Beam Computed Tomography (CBCT) data acquisition systems currently widely ava...
To study changes in tumor and normal organ size and/or position which occur during a course of radiation treatments.
Cone beam CT (CBCT) machines do not always allow for patients to be scanned in the ideal position for image acquisition. This study aimed to investigate the influence of the position/angulation of the...
To demonstrate a proof-of-concept for fast cone-beam CT (CBCT) intensity correction in projection space by the use of deep learning.
To assess the accuracy and efficiency of four different techniques, thus determining the optimum method for recalculating dose on cone beam CT (CBCT) images acquired during radiotherapy treatments.
This report describes upgrades and performance characterization of an experimental benchtop cone-beam x-ray fluorescence computed tomography (XFCT) system capable of determining the spatial distributi...
Scatter contamination constitutes a dominant source of degradation of image quality in cone-beam computed tomography (CBCT). We have recently developed an analytic image reconstruction method with a s...
Modality of computed tomography in which the patient is irradiated in a spiral path around the body with a cone or pyramid-shaped beam.
Computed tomography modalities which use a cone or pyramid-shaped beam of radiation.
Photosensitive proteins expressed in the CONE PHOTORECEPTOR CELLS. They are the protein components of cone photopigments. Cone opsins are classified by their peak absorption wavelengths.
The science and application of a double-beam transmission interference microscope in which the illuminating light beam is split into two paths. One beam passes through the specimen while the other beam reflects off a reference mirror before joining and interfering with the other. The observed optical path difference between the two beams can be measured and used to discriminate minute differences in thickness and refraction of non-stained transparent specimens, such as living cells in culture.
Photosensitive afferent neurons located primarily within the FOVEA CENTRALIS of the MACULA LUTEA. There are three major types of cone cells (red, blue, and green) with photopigments of different spectral sensitivity curves. Retinal cone cells operate in daylight vision (at photopic intensities) providing color recognition and central visual acuity.
