Introduction: Variable resolution x-ray (VRX) CT is a new type of CT that can image objects at various spatial resolutions. In a VRX CT scanner, the spatial resolution increases at the cost of reduction in the field of view (FOV). An important factor that limits the spatial resolution of the VRX CT is the effect of focal spot size. Also, the optimum magnification is different at each incident a...

In this paper I am describing a computer aided detection (CAD) method, which is able to detect lung nodules in medical data sets. The data sets are obtained by a high resolution computer tomography. The goal of the nodule detection is to gain an early nodule detection which increases the probability of survival. Introduced method is able to detect nodules of variable size and variable shape. It...

First arrivals of seismic waves were recorded along the Kamchatka arc using broadband seismic stations deployed for one year in 1998–1999. Cross correlation methods were used from a high resolution data set for tomographic inversion of body waves. The P-wave teleseismic tomography shows evidence of slab shoaling along the northern terminus of the Kamchatka subduction zone. Tomographic anomalies...

background: computed tomography (ct) scan is one the most useful devices in chest imaging. ct scan can be used in mediastinal abnormality, lungs, and pleural evaluations. according to the high prevalence and different causes of pulmonary nodules, we designed this study to evaluate the prevalence and the types of pulmonary nodules in noncancerous patients who underwent chest multi-detector ct (m...

A group of patients presenting with seizures (focal or generalised) and abnormal CT scans who, on follow up, showed complete resolution of the CT scan changes, without any treatment other than anticonvulsants, are described.

We describe the case of a 64 years-old woman admitted to Emergency Department ASST-Spedali Civili Brescia with fever and gastrointestinal symptoms 10 days after first dose ChAdOx1 nCov-19 vaccine. Laboratory investigations showed severe thrombocytopenia high D-dimer, while an abdominal CT scan reported partially occluding thrombosis superior mesenteric artery. Following treatment fondaparinux, ...

Computed laminography (CL) is an alternative to computed tomography if large objects are to be inspected with high resolution. This is especially true for planar objects. Algebraic reconstruction technique (ART) enhance the quality of laminographic images and permits scanning geometries which cannot be reconstructed by conventional tomosynthesis. Thus ART expands the capabilities of 3D inspecti...
