A laparoscopic surgery training interface
Queirós, Sandro Filipe Monteiro; Vilaça, João L.; Rodrigues, Nuno F.; Neves, Sara C.; Teixeira, Pedro M.; Correia-Pinto, JorgeLaparoscopy is a surgical procedure on which operations in the abdomen are performed through small incisions using several specialized instruments. The laparoscopic surgery success greatly depends on surgeon skills and training. To achieve these technical high-standards, different apprenticeship methods have been developed, many based on in vivo training, an approach that involves high costs and complex setup p...
Thoracic wall reconstruction using ultrasound images to model/bend the thoracic...
Fonseca, João; Moreira, António H. J.; Rodrigues, Pedro L.; Fonseca, Jaime C.; Pinho, A. C. Marques de; Rodrigues, Nuno F.; Pinto, Jorge CorreiaPectus 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...
A region-based algorithm for automatic bone segmentation in volumetric CT
Rodrigues, Pedro L.; Moreira, António Herculano Jesus; Fonseca, Jaime C.; Pinho, A. C. Marques; Rodrigues, Nuno F.; Vilaça, João L.In Computed Tomography (CT), bone segmentation is considered an important step to extract bone parameters, which are frequently useful for computer-aided diagnosis, surgery and treatment of many diseases such as osteoporosis. Consequently, the development of accurate and reliable segmentation techniques is essential, since it often provides a great impact on quantitative image analysis and diagnosis outcome. Th...

Rodrigues, PL; Vilaça, JL; Oliveira, C; Cicione, A; Rassweiler, J; Fonseca, J; Rodrigues, NF; Correia-Pinto, J; Lima, EPURPOSE: Precise needle puncture of the renal collecting system is a challenging and essential step for successful percutaneous nephrolithotomy (PCNL). This works aims to evaluate the efficiency of a new real-time electromagnetic tracking (EMT) system for in vivo kidney puncture. MATERIALS AND METHODS: Six anesthetized female pigs underwent ureterorenoscopies in order to place a catheter with an EMT sensor into...
Assessment of 3D scanners for modeling Pectus Carinatum corrective bar
Moreira, António Herculano Jesus; Fonseca, João Luís Gomes; Rodrigues, Pedro Miguel Loureiro; Fonseca, Jaime C.; Pinho, A. C. MarquesPectus 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...

Rodrigues, Pedro L.; Vilaça, João L.; Oliveira, Carlos; Cicione, Antonio; Rassweiler, Jens; Fonseca, Jaime; Rodrigues, Nuno F.; Pinto, Jorge CorreiaPURPOSE: 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 prebent customized prosthesis for pectus excavatum minimally invasive...
Vilaça, João L.; Rodrigues, Pedro L.; Soares, Tony Ramos; Fonseca, Jaime C.; Pinho, António C. M.; Coelho, Tiago Henriques; 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...
A new methodology for assessment of pectus excavatum correction after bar remov...
Fonseca, João Luís Gomes; Vilaça, João Luis Araújo Martins; Henriques-Coelho, Tiago; Direito-Santos, Bruno; Pinho, António C.M.; Fonseca, Jaime C.Purpose: The objective is to present a new methodology to assess quantitatively the impact of bar removal on the anterior chest wall, among patients with pectus excavatum who have undergone the Nuss procedure, and present a preliminary study using this methodology. Methods: We propose to acquire, for each patient, the surface of the anterior chest wall using a three-dimensional laser scanner at subsequent time ...
