IntroductionThe utility of evaluating a sagittal view CT the spine is well-known. In many clinical cases, includes noise generated from surrounding objects and may degrade image quality. Iterative reconstruction (IR) techniques are useful for reduction; however, they can reduce spatial resolution. The aim this study was to evaluate effectiveness adaptive statistical iterative (ASiR) generating ...

conclusion safire reconstruction provided better coronary image quality and displayed the number, morphology, and surrounding lumen of calcium plaques more accurately than traditional fbp reconstruction, with safire3 achieving the best results. results the subjective ratings of image quality using safire1–safire5 reconstructions were significantly higher than those using fbp, with safire3 achie...

As has already been shown with 2D-models DIRECTT (Direct iterative reconstruction of computed tomography trajectories) exceeds the spatial resolution of the classical filtered back projection. In this work the DIRECTT algorithm is extended towards cone-beam projection including iterative 3D reconstruction. The improved speed is still overcompensated by the large amount of reconstruction space a...

A challenge in photoacoustic tomography (PAT) brain imaging is to compensate for aberrations in the measured photoacoustic data due to their propagation through the skull. By use of information regarding the skull morphology and composition obtained from adjunct x-ray computed tomography image data, we developed a subject-specific imaging model that accounts for such aberrations. A time-reversa...

introduction: vertical root fracture (vrf) is common in endodontically treated teeth. conventional and digital radiographies have limitations for detection of vrfs. cone-beam computed tomography (cbct) offers greater detection accuracy of vrfs in comparison with conventional radiography. this study compared the effects of metal artifacts on detection of vrfs by using two cbct systems. methods a...

background: in many cases of ild (interstitial lung disease), overlap diagnosis is considered. here, a few cases with diagnosis of a variety of ilds, where eventual open lung biopsy has been performed are selected. reference will be made to reliable sources to show that nsip can still be a variant of uip (usual interstitial pneumonia) with better treatment response and prognosis. case presentat...
