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 ...

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...

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...
Automatic segmentation and 3D feature extraction of protein aggregates in Caeno...
Rodrigues, Pedro L.; Moreira, António H. J.; Teixeira-Castro, Andreia; Oliveira, João; Dias, Nuno; F. Rodrigues, Nuno; Vilaça, João L.In the last years, it has become increasingly clear that neurodegenerative diseases involve protein aggregation, a process often used as disease progression readout and to develop therapeutic strategies. This work presents an image processing tool to automatic segment, classify and quantify these aggregates and the whole 3D body of the nematode Caenorhabditis Elegans. A total of 150 data set images, containing ...

Moreira, António H. J.; Rodrigues, Pedro L.; Fonseca, Jaime C.; Pinho, A. C. Marques de; Rodrigues, Nuno F.; Pinto, Jorge Correia; Vilaça, João L.Pectus excavatum is the most common congenital deformity of the anterior chest wall, in which an abnormal formation of the rib cage gives the chest a caved-in or sunken appearance. Today, the surgical correction of this deformity is carried out in children and adults through Nuss technic, which consists in the placement of a prosthetic bar under the sternum and over the ribs. Alth ough this technique has been ...

Vilaça, João L.; Moreira, António H. J.; L-Rodrigues, Pedro; F. Rodrigues, Nuno; Fonseca, Jaime C.; Correia-Pinto, JorgePectus excavatum is the most common congenital deformity of the anterior chest wall, in which several ribs and the sternum grow abnormally. Nowadays, the surgical correction is carried out in children and adults through Nuss technic. This technic has been shown to be safe with major drivers as cosmesis and the prevention of psychological problems and social stress. Nowadays, no application is known to predict t...
