Voxel-based registration of simulated and real patient CBCT data for accurate d...
Moreira, António H. J.; Queirós, Sandro; Morais, Pedro; Rodrigues, Nuno F.; Correia, André Ricardo; Fernandes, Valter; Pinho, ACM; Fonseca, Jaime C.The success of dental implant-supported prosthesis is directly linked to the accuracy obtained during implant’s pose estimation (position and orientation). Although traditional impression techniques and recent digital acquisition methods are acceptably accurate, a simultaneously fast, accurate and operator-independent methodology is still lacking. Hereto, an image-based framework is proposed to estimate the pat...
Automatic modeling of pectus excavatum corrective prosthesis using artificial n...
Rodrigues, Pedro L.; F. Rodrigues, Nuno; Pinho, ACM; Fonseca, Jaime C.; Correia-Pinto, Jorge; Vilaça, João L.Pectus excavatum is the most common deformity of the thorax. Pre-operative diagnosis usually includes Computed Tomography (CT) to successfully employ a thoracic prosthesis for anterior chest wall remodeling. Aiming at the elimination of radiation exposure, this paper presents a novel methodology for the replacement of CT by a 3D laser scanner (radiation-free) for prosthesis modeling. The complete elimination of...

Vilaça, João L.; Rodrigues, Pedro L.; Soares, Tony R.; Fonseca, Jaime; Pinho, ACM; Henriques-Coelho, Tiago; Correia-Pinto, JorgePectus excavatum is the most common deformity of the thorax. A minimally invasive surgical correction is commonly carried out to remodel the anterior chest wall by using an intrathoracic convex prosthesis in the substernal position. The process of prosthesis modeling and bending still remains an area of improvement. The authors developed a new system, i3DExcavatum, which can automatically model and bend the bar...
