For X-ray microtomography, powerful open source software is available, such as the ASTRA toolbox. [ 8 ] [ 9 ] The ASTRA Toolbox is a MATLAB and python toolbox of high-performance GPU primitives for 2D and 3D tomography, from 2009 to 2014 developed by iMinds-Vision Lab , University of Antwerp and since 2014 jointly developed by iMinds-VisionLab ...
Practical reconstruction algorithms have been developed to implement the process of reconstruction of a three-dimensional object from its projections. [3] [2] These algorithms are designed largely based on the mathematics of the X-ray transform, statistical knowledge of the data acquisition process and geometry of the data imaging system.
Projectional radiography, also known as conventional radiography, [1] is a form of radiography and medical imaging that produces two-dimensional images by X-ray radiation.The image acquisition is generally performed by radiographers, and the images are often examined by radiologists.
[1] [2] [3] In a map projection, coordinates, often expressed as latitude and longitude, of locations from the surface of the globe are transformed to coordinates on a plane. [4] [5] Projection is a necessary step in creating a two-dimensional map and is one of the essential elements of cartography.
Taking an X-ray image with early Crookes tube apparatus, late 1800s. Radiography's origins and fluoroscopy's origins can both be traced to 8 November 1895, when German physics professor Wilhelm Conrad Röntgen discovered the X-ray and noted that, while it could pass through human tissue, it could not pass through bone or metal.

The Monument to the X-ray and Radium Martyrs of All Nations (also known as the X-ray Martyrs' Memorial) is a memorial in Hamburg, Germany, commemorating those who died due to their work with the use of radiation, particularly X-rays, in medicine.
The Troyanovo-1 coal mine is a large coal mine located in Burgas Province. Troyanovo-1 represents one of the largest coal reserve in Bulgaria having estimated reserves of 525.3 million tonnes of coal and an annual coal production of around 8 million tonnes. [1] [2]
Ruse (also transliterated as Rousse, Russe; Bulgarian: Русе) is the fifth largest city in Bulgaria.Ruse is in the northeastern part of the country, on the right bank of the Danube, opposite the Romanian city of Giurgiu, approximately 67 km (42 mi) south of Bucharest, Romania's capital, 172 km (107 mi) from Varna, and 249 km (155 mi) from the capital Sofia.
