A Digital Game Development Education Project
F. Rodrigues, Nuno; Simões, Ricardo; L. Vilaça, JoãoThe success of the digital game industry is spawning several undergraduate degrees aiming at the training of digital game developers. Building adequate new courses curricula is not a trivial task and demands a profound analysis of the scientific areas to introduce as well as the dependencies throughout the entire degree. Another important aspect of every academic educational plan are the satellite projects that...
Application to quantify fetal lung branching on rat explants
Rodrigues, Pedro L.; Granja, Sara; Moreira, António; F. Rodrigues, Nuno; Vilaça, João L.Recently, regulating mechanisms of branching morphogenesis of fetal lung rat explants have been an essential tool for molecular research. The development of accurate and reliable segmentation techniques may be essential to improve research outcomes. This work presents an image processing method to measure the perimeter and area of lung branches on fetal rat explants. The algorithm starts by reducing the noise c...
Assessment of 3D scanners for modeling Pectus Carinatum corrective bar
Moreira, António H. J.; Fonseca, João Gomes; Rodrigues, Pedro L.; Fonseca, Jaime C.; Pinho, A.C.M.; Correia-Pinto, Jorge; F. Rodrigues, NunoPectus Carinatum (PC) is a chest deformity consisting on the anterior protrusion of the sternum and adjacent costal cartilages. Non-operative corrections, such as the orthotic compression brace, require previous information of the patient chest surface, to improve the overall brace fit. This paper focuses on the validation of the Kinect scanner for the modelling of an orthotic compression brace for the correcti...
Variations of the soft tissue thicknesses external to the ribs in Pectus Excava...
Rodrigues, Pedro L.; Direito-Santos, Bruno; Moreira, António H. J.; Fonseca, Jaime C.; Pinho, A.C.M.; F. Rodrigues, Nuno; Henriques-Coelho, TiagoBackground: Surgical repair of pectus excavatum (PE) has become more popular due to improvements in the minimally invasive Nuss procedure. The pre-surgical assessment of PE patients requires Computerized Tomography (CT), as the malformation characteristics vary from patient to patient. Objective: This work aims to characterize soft tissue thickness (STT) external to the ribs among PE patients. It also presents ...
Kidney targeting and puncturing during percutaneous nephrolithotomy: recent adv...
Rodrigues, Pedro L.; F. Rodrigues, Nuno; Fonseca, Jaime; Lima, Estevão; Vilaça, João L.Background and Purpose: Precise needle puncture of the kidney is a challenging and essential step for successful percutaneous nephrolithotomy (PCNL). Many devices and surgical techniques have been developed to easily achieve suitable renal access. This article presents a critical review to address the methodologies and techniques for conducting kidney targeting and the puncture step during PCNL. Based on this s...
Collecting system percutaneous access using real-time tracking sensors: first p...
Rodrigues, Pedro L.; Vilaça, João L.; Oliveira, Carlos; António, Cicione; Rassweiler, Jens; Fonseca, Jaime; F. Rodrigues, Nuno; Correia-Pinto, JorgePurpose: Precise needle puncture of the renal collecting system is an essential but challenging step for successful percutaneous nephrolithotomy. We evaluated the efficiency of a new real-time electromagnetic tracking system for in vivo kidney puncture. Materials and Methods: Six anesthetized female pigs underwent ureterorenoscopy to place a catheter with an electromagnetic tracking sensor into the desired punc...
Automatic modeling of an orthotic bracing for nonoperative correction of Pectus...
Vila, João L.; Rodrigues, Pedro L.; Moreira, António H. J.; Fonseca, Jaime C.; F. Rodrigues, NunoPectus Carinatum is a deformity of the chest wall, characterized by an anterior protrusion of the sternum, often corrected surgically due to cosmetic motivation. This work presents an alternative approach to the current open surgery option, proposing a novel technique based on a personalized orthosis. Two different processes for the orthosis’ personalization are presented. One based on a 3D laser scan of the pa...
Finite element analysis of pectus carinatum surgical correction via a minimally...
Neves, Sara C.; Pinho, António C.M.; Fonseca, Jaime C.; F. Rodrigues, Nuno; Henriques-Coelho, Tiago; Correia-Pinto, Jorge; Vilaça, João L.Pectus carinatum (PC) is a chest deformity caused by a disproportionate growth of the costal cartilages compared to the bony thoracic skeleton, pulling the sternum towards, which leads to its protrusion. There has been a growing interest on using the ‘reversed Nuss’ technique as minimally invasive procedure for PC surgical correction. A corrective bar is introduced between the skin and the thoracic cage and pos...
Type checking cryptography implementations
Barbosa, Manuel; Moss, Andrew; Page, Dan; F. Rodrigues, Nuno; Silva, Paulo F.Cryptographic software development is a challenging eld: high performance must be achieved, while ensuring correctness and com- pliance with low-level security policies. CAO is a domain speci c language designed to assist development of cryptographic software. An important feature of this language is the design of a novel type system introducing native types such as prede ned sized vectors, matrices and bit st...
Thoracic wall reconstruction using ultrasound images to model/bend the thoracic...
Fonseca, João Gomes; Moreira, António H. J.; Rodrigues, Pedro L.; Fonseca, Jaime; Pinho, A.C.M; Correia-Pinto, Jorge; F. Rodrigues, NunoPectus excavatum is the most common congenital deformity of the anterior thoracic wall. The surgical correction of such deformity, using Nuss procedure, consists in the placement of a personalized convex prosthesis into sub-sternal position to correct the deformity. The aim of this work is the CT-scan substitution by ultrasound imaging for the pre-operative diagnosis and pre-modeling of the prosthesis, in order...
