Maior Sinagoga da Península Ibérica: onde pára a polícia?

A História da Sinagoga Kadoorie está ligada a Artur Carlos de Barros Basto (1887-1961), Militar português que, descobrindo a sua origem judaica, se converteu ao judaísmo, passando a chamar-se Abraham Israel Ben-Rosh. Foi condecorado por ser um soldado valente na frente de batalha, na 1ª Guerra Mundial na Flandres. Já no Porto, ajuda centenas de judeus escapados ao holocausto a começar uma nova vida. Tal como o valente Cônsul Aristides de Sousa Mendes, foi perseguido por Salazar, tendo sido mesmo afastado do exército. Somente foi reabilitado, já morto, em 2012. § The History of Kadoorie Synagogue is linked to Artur Carlos de Barros Basto (1887-1961), Military Portuguese who discovered his Jewish origin, converted to Judaism, going to be called Abraham Israel Ben-Rosh.

Robust temporal alignment of multimodal cardiac sequences

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, we derive a robust, modality-independent signal from the image sequences, estimated by computing the normalized crosscorrelation between each frame in the temporal sequence and the end-diastolic frame. This signal is a resembler for the left-ventricle (LV) volume curve over time, whose variation indicates di erent temporal landmarks of the cardiac cycle. We then perform the temporal alignment of these surrogate signals derived from MRI and US sequences of the same patient through Dynamic Time Warping (DTW), allowing to synchronize both sequences. The proposed framework was evaluated in 98 patients, which have undergone both 3D+t MRI and US scans. The end-systolic frame could be accurately estimated as the minimum of the image-derived surrogate signal, presenting a relative error of 1:6 1:9% and 4:0 4:2% for the MRI and US sequences, respectively, thus supporting its association with key temporal instants of the cardiac cycle. The use of DTW reduces the desynchronization of the cardiac events in MRI and US sequences, allowing to temporally align multimodal cardiac imaging sequences. Overall, a generic, fast and accurate method for temporal synchronization of MRI and US sequences of the same patient was introduced. This approach could be straightforwardly used for the correct temporal alignment of pre-operative MRI information and intra-operative US images.
