In this paper we present an efficient implementation of an algorithm for reconstructing a 3D volume from limited angle projection data, based on statistical inversion theory. We demonstrate the strength of the method for detecting structural defects in large composite aerospace components, whose dimensions prevent acquiring measurements over the full circle. In comparison with a number of other...

A novel reconstruction technique, called Wiener Filtered Reconstruction Technique (WIRT), for sparse-data tomographic imaging is introduced. This six-step method applies a spatially varying constrained leastsquares filter combined with a regularization method based on total variation. The WIRT reconstruction is implemented in the frequency domain, where the information based on measurements and...

introduction: reconstruction of intraoral soft tissue defects is important in restoring function and esthetic. in large defects, there will be demand for regional pedicle flaps or free flaps. hard palate separates nasal and oral cavities. due to the small surface area between flap and remaining palate after surgical resections, optimal blood supply of the flaps for hard palate reconstructions a...

Background: Multiligament knee injury (MLKI) is a complex orthopedic injury leading to the tear of at least two ofthe major knee ligaments. However, there is no consensus on the optimal management of this debilitating condition.Regarding this, the present study was performed to evaluate the outcomes of single-stage multiligament reconstructionsurgery in patients with MLKI.<br ...

Dear Editor,We have greatly enjoyed reading the case report entitled “‘Femoral Condyle Fracture during Revision of Anterior Cruciate Ligament Reconstruction: Case Report and a Review of Literature in the issue of Arch Bone Jt Surg. 2015;3(2) with great interest. We would like to commend the authors for their detailed and valuable work. Although various case reports have described postoperative ...

Background: Nowadays combined high tibial osteotomy and ACL reconstruction is accepted as a safe and effectivesurgery for patients with symptomatic varus osteoarthritis and anterior knee instability; however, the source of varusdeformity is sometimes the femoral bone. No studies have reported concomitant ACL reconstruction and distal femoralosteotomy in ACL-deficient knees wit...

background: no uniform consensus exists to decide type of fixation for arthroscopic anterior cruciate ligament reconstruction. hypothsis: there is similar functional outcome after rigid fix compared to other methods of fixation which has been published. study design: retrospective observational study. methods: a total of 50 patients underwent arthroscopic anterior cruciate ligament reconstructi...

Neurocognitive motor tasks have been shown to have an effective relationship with athletic performance and musculoskeletal injuries. Cognitive changes following anterior cruciate ligament reconstruction surgery may lead to adverse knee biomechanical changes and an increased risk of secondary injury. This study aimed to compare the kinetics of athletes with a history of ACL reconstruction and th...
