Ct-to-body divergence
WebA recent pilot study utilizing cone beam CT (CBCT) in conjunction with thin or ultrathin bronchoscopy and rEBUS demonstrated an improvement in yield from 50% to 70% after the introduction of CBCT, without the use of ENB. 4 In a retrospective study of 75 patients with a mean peripheral nodule size of 16 mm, CBCT combined with ENB resulted in a ... WebAug 9, 2024 · Centering the anatomy to the central ray on the image receptor will limit beam distortion due to divergence. The point of the central ray is the focal spot on the x-ray tube; therefore one can angle the tube on a stationary axis and maintain the central ray at the level of the joint, seldom applied but useful for imaging that requires longer ...
