Sentence examples for ct beam from inspiring English sources

On CT, beam hardening artefacts may obscure or mimic bilateral temporal lobe disease.

We assume (E_{text {eff}}= frac {E_{text {peak}}}{3}), with Epeak the maximum energy of the CT beam.

As a result, the attenuation of the CT beam is much less for the cadaver ear and should provide a much better signal to noise ratio when compared to a comparable in vivo image data set.

The attenuation correction was also performed according to the manufacturer's formula, reported, and validated in [13], see Eq. 9, with μ m, μ w, μ a, and μ b the attenuation coefficients of respectively material, water, air, and bone, E the energy of the gamma photons in keV, and Eeff the mean energy of the CT beam.

Hybrid imaging (PET-CT, SPECT-cone beam CT).

Hybrid imaging (PET-CT, SPECT-cone beam CT) Imaging during pregnancy and in childhood as well as young adults Imaging in disease requiring periodic follow-up examinations Occupational exposure (http://www.cirse.org/files/File/SOP/Occupational%20radiation%20radiationn%20radiationerventionalists%20radiation).

Typical findings are illustrated and the respective roles of computed tomography (CT), cone beam CT (CBCT), magnetic resonance imaging (MRI) with diffusion-weighted imaging (DWI) sequences and ultrasonography (US) are discussed for the pre-therapeutic assessment, complex treatment planning and post-treatment surveillance.

In multislice row CT, thick beam collimation has better radiation utilization [ 27].

Practitioners and researchers have been investigating the magnitude of catheter displacements and their effects on dosimetry by using films, 94 fluoroscopy images, 93 helical CT, 95– 100 cone beam CT, 101, 102 or CT/MR scans.

In addition to free-hand positioning and fluoroscopy-guided techniques, several different tomographic imaging techniques (3D fluoroscopy, cone beam CT, intraoperative CT scan) have contributed to greater intraoperative precision in positioning pedicle screws [ 28– 30].

The comparability of electron beam CT and multidetector CT has been demonstrated previously (14).
