Assessment of the potential of convolutional neuronal networks in the different...
Valador, N.; Oliveira, F. P.; Ferreira, P. M.; Vieira, Lina Oliveira; Costa, D. C.Aim/Introduction: To evaluate the potential of convolutional neural networks (CNN) in the differential diagnosis of Parkinson’s disease (PD) based on [123I]FP-CIT single-photon emission computed tomography (SPECT) images, compared to other machine learning-based classifiers. Materials and Methods: This work included 806 [123I]FP-CIT SPECT brain images (208 health controls and 598 with PD). Data were obtained fr...
Using 3D anthropometric data for the modelling of customised head immobilisatio...
Loja, MAR; Sousa, Eva; Vieira, Lina Oliveira; Costa, D. M.; Craveiro, D. S.; Parafita, R.; Costa, D. C.Head immobilization thermoplastic masks for radiotherapy purposes involve a distressful modeling procedure for the patient. To assess the possibility of using different acquisition and reconstruction methods to obtain a 3D skin surface model of PIXY-phantom-head and to present a proposal of an alternative head immobilization mask prototype. Phantom head geometry acquisitions using: computed tomography (reconstr...

Comparison between 3D laser scanning and computed tomography on the modelling o...
Sousa, E.; Vieira, L.; Costa, D. M. S.; Costa, D. C.; Parafita, R.; Loja, AméliaThe measurement of people physical parameters and proportions constitutes an importante field of science, the anthropometry, since it is related to the characterization of the human size and constitution; it allows improving the design and sizing of systems and devices to human use. To enable these measurements, different direct and indirect methodologies may be used depending on the particular aim of a specifi...
