WebAug 1, 2008 · The cone beam scan acquires the image using a radiation source opposing a target sensor on a rotating mechanism. The X-ray is focused (collimated) at its source and then diverges into a fan shape by the time it reaches the detectors, hence the name cone beam. This fan beam collimation is the major difference between the medical CT … WebCone-beam CT for enhanced bronchoscopic access to pulmonary nodules. Peripheral pulmonary nodules are a common abnormality seen by pulmonologists. In some cases, nodules are best managed by serial imaging to assess for interval growth. Alternatively, if the pretest probability of malignancy exceeds 70 percent, a lung nodule or mass may be ...
