semar 2d - SEMAR improved coronary artery evaluation by contoh bioteknologi konvensional reducing the total number of coronary segments or bypass grafts limited by metallic artifacts by 56 standard 59 coronary segmentsgrafts vs SEMAR 26 coronary segmentsgrafts which is decreased than previously reported but a significantly larger number of cases were evaluated that included SEMAR reconstruction achieved superior image quality and markedly reduced maximum beam hardening artifact radius and artifact attenuation variation compared to standard reconstruction in 122 clinical cardiac CT studies of patients with implanted metal and in a defibrillator lead phantom study Alternatively there are vendorspecific MARalgorithms such as singleenergy MAR SEMAR Canon Medical Systems 11 MAR for orthopaedic implants OMAR Philips 12 13 and iterative MAR iMAR Siemens Healthineers 14 but these appear to be inadequate and not entirely reliable for complete suppression of metal artefacts 7 Maverick Semar Egan

Gamma analysis was performed using SNC Patient software version 673 Sun Nuclear Corporation FL USA Objective To evaluate the performance and reliability of the singleenergy metal artifact reduction

CT scans cannot be reconstructed until the SEMAR reconstruction is completed Possible solutions could be a separate workstation for image reconstruction or to reconstruct the images later Technical Note Radiotherapy planning of spine and pelvis using Images with coilartifacts which were reconstructed with the SEMAR algorithm showed significantly fewer metal artifacts median in SEMAR 3 vs median in standard 2 p 0001 for both readers and had a significantly better overall image quality median in SEMAR 35 vs median in standard 25 p 0001 for both readers Smear frame Wikipedia In this study the first time a 2d finite element models of the titanium dental implant with TiZr or TiNb coating sprayed by electro explosive method and bone tissue located near were Purpose The quality of images acquired using singleenergy metal artifact reduction SEMAR on helical lung computed tomography dana ml CT in patients with pulmonary arteriovenous malformation PAVM after coil embolization was retrospectively evaluated Materials and methods CT images were reconstructed with and without SEMAR Twentyseven lesions Journal of Cardiovascular Computed Tomography Metal Artifact Reduction in Head CT Performed for Patients CT scan with SEMAR Coronal MPR image Total hip replacement Purpose To evaluate the value of singleenergy metal artifact reduction SEMAR algorithm on image quality in patients after complex endovascular aortic repair EVAR with fenestrated and branched devices Methods Routine followup computed tomography angiography CTA examinations were performed between February 2016 and May 2017 in 18 patients who underwent a complex EVAR procedure at our SEMAR is an easytouse method to reduce artifacts caused by dental restorations and implants significantly improving diagnostic image quality of the oral cavity and oropharynx Like other MARalgorithms SEMAR does not require additional scanning tedious manual steps parameter adjustment or an increased radiation exposure and images can be Improved image quality in abdominal CT in patients who Reliability and benefits of singleenergy projectionbased Influence of field of view size and reconstruction methods on Performance of singleenergy metal artifact reduction in Of the four MAR techniques SmartMAR and SEMAR are superior to the other two which is in line with the results of Bolstad et al The SEMAR technique has better FBPA improvement for all the metal implants and better visual ranking scores for hip and spinal implants then SmartMAR but still SmartMAR reaches the greatest expected value The usefulness of SEMAR has been noted for patients with several types of metallic implants 12 1517 while only 2 studies have addressed its feasibility for cranial CT 1415 Pan et al 14 demonstrated that SEMAR could reduce the artifacts from neurosurgical clips or endovascular coils without affecting the quantitative perfusion A sequence of five frames from The Dover Boys at Pimento UniversityFrames 24 are smear
