Predicting hospital emergency department visits accurately: a systematic review

Silva, Eduardo; Pereira, Margarida F.; Vieira, Joana T.; Ferreira-Coimbra, João; Henriques, Mariana; Rodrigues, Nuno F.

The emergency department (ED) is a very important healthcare entrance point, known for its challenging organisation and management due to demand unpredictability. An accurate forecast system of ED visits is crucial to the implementation of better management strategies that optimise resources utilization, reduce costs and improve public confidence. The aim of this review is to investigate the different factors t...


The effects and viability of video games on the rehabilitation of schizophrenic...

Pinto, Gonçalo; Barroso, Bárbara; Rodrigues, Nuno F.; Guimarães, Manuel; Oliveira, Eva

Background: Schizophrenia is the most common psychotic illness in the world. The negative and cognitive symptoms of this mental disorder often prevent full reintegration of patients into society, and cannot be effectively addressed with drugs alone, relying on therapy and rehabilitation. Video games as a digital tool for rehabilitation and therapy can help promote accessibility, improve patient engagement and r...

Automatic strategy for extraction of anthropometric measurements for the diagno...

Oliveira, Bruno; Torres, Helena R.; Veloso, Fernando; Vilhena, Estela; Rodrigues, Nuno F.; Fonseca, Jaime C.; Morais, Pedro; Vilaça, João L.

Deformational Plagiocephaly (DP) refers to an asymmetrical distortion of an infant’s skull resulting from external forces applied over time. The diagnosis of this condition is performed using asymmetry indexes that are estimated from specific anatomical landmarks, whose are manually defined on head models acquired using laser scans. However, this manual identification is susceptible to intra-/inter-observer var...

Automated Image Analysis of Lung Branching Morphogenesis from Microscopic Image...

Rodrigues, Pedro L.; Rodrigues, Nuno F.; Duque, Duarte; Granja, Sara; Vilaça, João L.

Background. Regulating mechanisms of branching morphogenesis of fetal lung rat explants have been an essential tool for molecular research. This work presents a new methodology to accurately quantify the epithelial, outer contour, and peripheral airway buds of lung explants during cellular development from microscopic images. Methods. The outer contour was defined using an adaptive and multiscale threshold algo...

Segmentation of kidney and renal collecting system on 3D computed tomography im...

Oliveira, Bruno; Torres, Helena Daniela Ribeiro; Queirós, Sandro Filipe Monteiro; Morais, Pedro; Fonseca, Jaime C.; D'hooge, Jan; Rodrigues, Nuno F.

Surgical training for minimal invasive kidney interventions (MIKI) has huge importance within the urology field. Within this topic, simulate MIKI in a patient-specific virtual environment can be used for pre-operative planning using the real patient's anatomy, possibly resulting in a reduction of intra-operative medical complications. However, the validated VR simulators perform the training in a group of stand...


Dense motion field estimation from myocardial boundary displacements

Morais, Pedro; Queirós, Sandro; Ferreira, Adriano; Rodrigues, Nuno F.; Baptista, Maria J.; D’hooge, Jan; Vilaça, João L.; Barbosa, Daniel

Minimally invasive cardiovascular interventions guided by multiple imaging modalities are rapidly gaining clinical acceptance for the treatment of several cardiovascular diseases. These images are typically fused with richly detailed pre-operative scans through registration techniques, enhancing the intra-operative clinical data and easing the image-guided procedures. Nonetheless, rigid models have been used to...

Accuracy Comparison of Implant Impression Techniques: A Systematic Review

Moreira, António H. J.; Rodrigues, Nuno F.; Pinho, António C.M.; Fonseca, Jaime C.; Vilaça, João L.

Background: Several studies link the seamless fit of implant-supported prosthesis with the accuracy of the dental impression technique obtained during acquisition. In addition, factors such as implant angulation and coping shape contribute to implant misfit. Purpose: The aim of this study was to identify the most accurate impression technique and factors affecting the impression accuracy. Material and Methods: ...

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...

Robust temporal alignment of multimodal cardiac sequences

Perissinotto, Andrea; Queirós, Sandro; Morais, Pedro; Baptista, Maria J.; Monaghan, Mark; Rodrigues, Nuno F.; Vilaça, João L.; Barbosa, Daniel

Given the dynamic nature of cardiac function, correct temporal alignment of pre-operative models and intraoperative images is crucial for augmented reality in cardiac image-guided interventions. As such, the current study focuses on the development of an image-based strategy for temporal alignment of multimodal cardiac imaging sequences, such as cine Magnetic Resonance Imaging (MRI) or 3D Ultrasound (US). First...
