CT numbers and noise were measured on images with and without the VOI filter. Radiation dose with and without the VOI filter was estimated using 16 projection views over a 180 range where the VOI filter was manually placed in the x-ray beam.. A simulated VOI study was also performed using...

We propose a statistical penalized weighted least-squares (PWLS) method to reconstruct two basis material images from a single-energy CT scan acquired with a simple split X-ray filter. Methods: We used a pre-patient split-filter that contains 2mm aluminum across half the fan beam and 200 ...

In addition to reducing scan time, helical scanning provides other advantages such as better use of injected contrast, improved image reconstruction at arbitrary locations, and better three-dimensional images. In known CT systems the x-ray beam is projected from the x-ray source through a pre-...
Reduction in x-ray scatter and radiation dose for volume-of-interest (VOI) cone-beam breast CT—a phantom study With volume-of-interest (VOI) cone-beam computed tomography (CBCT) imaging, one set of projection images are acquired with the VOI collimator at a regular ... C Lai,L Chen,H...
An FDG PET/CT was performed to evaluate a tracheal nodule, which was revealed by chest CT. The PET/CT images showed increased FDG uptake with SUVmax of 3.3 in the known tracheal lesion. The results of pathological examination ...
