Figure 1 shows an example of a light field camera with a pinhole mask in front of the sensor. If we look at the sensor in 1D and assume an total x-resolution of 900 pixels and a Θ resolution of 9, the local x resolution is 100. The disadvantages are therefore a loss in resolution and a loss of light, as most of the light gets blocked by the mask. Therefore, while this model is very clean on a t...

Background: Angiogenesis is a key phenomenon for tumour progression, diagnosis and treatment in brain tumours and more generally in oncology. Presently, its precise, direct quantitative assessment can only be done on whole tissue sections immunostained to reveal vascular endothelial cells. But this is a tremendous task for the pathologist and a challenge for the computer since digitised whole t...

Computed tomography (CT) angiography is a useful imaging technique for the evaluation of the intraand extra-cranial vasculature. With the introduction of multi-detector row CT scanners, head and neck CT angiography images make it easy to detect cerebral aneurysms, arterial stenosis, and other vascular anomalies. To get an arterial anatomy in three-dimensional views, CT angiography images are of...

Since the release of COVID-19 epidemic in late December 2020, recommendations issued for personal protection by the World Health Organization and National Health Organizations around the world. The most prominent of which has the use of masks to prevent the spread of the virus. Despite the importance of this solution, many people still resist using the mask. Therefore, this study, by emphasizin...

STUDY OBJECTIVE Although preoxygenation for emergency airway management is usually performed with nonrebreather face masks or bag-valve-mask devices, some clinicians also deliver supplemental high-flow oxygen by nasal cannula. We aim to measure the efficacy of supplemental nasal cannula oxygen delivery to conventional bag-valve-mask and nonrebreather face mask preoxygenation both with and witho...

coronary artery anomalies are rare, with their incidence varying from 1 to 5%. angiography is a commonly used modality for the assessment of coronary artery anomalies. based on previous reports, a majority of coronary artery anomalies are of origin or distribution, with separate ostia of the left anterior descending artery and left circumflex artery. coronary artery anomalies may cause myocardi...

Masked logic styles use a random mask bit to de-correlate the power consumption of the circuit from the state of the algorithm. The effect of the random mask bit is that the circuit switches between two complementary states with a different power profile. Earlier work has shown that the mask-bit value can be estimated from the power consumption profile, and that masked logic remains susceptible...
