DiffeoRaptor: diffeomorphic inter-modal image registration using RaPTOR
Springer Science and Business Media LLC - Tập 18 - Trang 367-377 - 2022
Diffeomorphic image registration is essential in many medical imaging applications. Several registration algorithms of such type have been proposed, but primarily for intra-contrast alignment. Currently, efficient inter-modal/contrast diffeomorphic registration, which is vital in numerous applications, remains a challenging task. We proposed a novel inter-modal/contrast registration algorithm that...... hiện toàn bộ
Wire-driven flexible manipulator with constrained spherical joints for minimally invasive surgery
Springer Science and Business Media LLC - Tập 14 - Trang 1365-1377 - 2019
One of the main factors that affect the rigidity of flexible robots is the twist deformation because of the external force exerted on the end effector. Another important factor that affects accuracy is the fact that such robots do not have a constant curvature. The conventional kinematic model assumes that the curvature is constant; however, in reality, it is not. To improve the rigidity and accur...... hiện toàn bộ

Clinical, functional, and radiographic outcomes following total knee arthroplasty with patient-specific instrumentation, computer-assisted surgery, and manual instrumentation: a short-term follow-up study
Springer Science and Business Media LLC - Tập 9 - Trang 837-844 - 2013
The purpose of this study was to evaluate clinical, functional, and radiographic outcomes following total knee arthroplasty (TKA) performed with patient-specific instrumentation (PSI), computer-assisted surgery (CAS), and manual instruments at short-term follow-up. 122 TKAs were performed by a single surgeon: 42 with PSI, 38 with CAS, and 40 with manual instrumentation. Preoperative, 1-month...... hiện toàn bộ
Ultrasound texture-based CAD system for detecting neuromuscular diseases
Springer Science and Business Media LLC - Tập 10 - Trang 1493-1503 - 2014
Diagnosis of neuromuscular diseases in ultrasonography is a challenging task since experts are often unable to discriminate between healthy and pathological cases. A computer-aided diagnosis (CAD) system for skeletal muscle ultrasonography was developed and tested for myositis detection in ultrasound images of biceps brachii. Several types of features were extracted from rectangular and polygonal ...... hiện toàn bộ
Towards real-time, tracker-less 3D ultrasound guidance for spine anaesthesia
Springer Science and Business Media LLC - Tập 10 - Trang 855-865 - 2015
Epidural needle insertions and facet joint injections play an important role in spine anaesthesia. The main challenge of safe needle insertion is the deep location of the target, resulting in a narrow and small insertion channel close to sensitive anatomy. Recent approaches utilizing ultrasound (US) as a low-cost and widely available guiding modality are promising but have yet to become routinely ...... hiện toàn bộ
Design of a force-measuring setup for colorectal compression anastomosis and first ex-vivo results
Springer Science and Business Media LLC - Tập 16 - Trang 1335-1345 - 2021
The introduction of novel endoscopic instruments is essential to reduce trauma in visceral surgery. However, endoscopic device development is hampered by challenges in respecting the dimensional restrictions, due to the narrow access route, and by achieving adequate force transmission. As the overall goal of our research is the development of a patient adaptable, endoscopic anastomosis manipulator...... hiện toàn bộ
DICOM data migration for PACS transition: procedure and pitfalls
Springer Science and Business Media LLC - Tập 10 - Trang 1055-1064 - 2014
Transition from one Picture Archiving and Communication System (PACS) to the other is costly and disruptive. Especially the migration of the DICOM data from the legacy to the new PACS is a very challenging task, and although such a migration will happen in every hospital, literature on methodologies to follow and possible problems and pitfalls is scarce. The objective of this work is to provide in...... hiện toàn bộ
