The purpose of this study was to evaluate the clinical accuracy of femoral canal preparation using postoperative reconstructed computed tomography (CT) images of 75 consecutive total hip arthroplasties performed with a two-pin-based ROBODOC system. Intraoperatively, the robot milled the femoral canal according to the preoperative planning performed with preoperative CT data and the ROBODOC work...

Diversity in data is critical for the successful training of deep learning models. Leveraged by a recurrent generative adversarial network, we propose CT-SGAN model that generates large-scale 3D synthetic CT-scan volumes (\({\ge }224\times 224\times 224\)) when trained on small dataset chest CT-scans. offers an attractive solution to two major challenges facing machine medical imaging: number g...

OBJECTIVE In this paper, we present an autonomous virtual mobile robot (AVMR) for three-dimensional (3D) exploration of unknown tubular-like structures in 3D images. METHODS AND MATERIALS The trajectory planning for 3D central navigation is achieved by combining two neuro-fuzzy controllers, and is based on 3D sensory information; a Hough transform is used to locally fit a cylinder during the ...

introduction: mandibular fracture is the most common facial bone fracture due to facial trauma. a variety of imagings have been used for diagnosis of mandibular fractures. however, the choice of imaging for diagnosis of mandibular fractures is controversial.present study compares the accuracy of the three most common imaging methods in mandibular fracture diagnosis panoramic radiography, corona...

UNLABELLED Small-animal imaging systems are often characterized using phantoms, which may not predict performance in clinical applications. An implantable synthetic SPECT lesion would facilitate characterization of lesion detectability in a living animal. METHODS Anion-exchange columns with bed volumes of 100-300 nL were constructed from medical-grade polyvinyl chloride tubing and resin. The ...

Background The superior soft tissue contrast of magnetic resonance imaging (MRI) compared to computed tomography (CT) has urged the integration of MRI and exclusion of CT in prostate radiotherapy treatment, referred to as an MRI-only workflow. Such a workflow can eliminate image registration errors between the CTand MR-images but incorporates multiple challenges. MR-images lack electron density...
