The computing device is configured to determine a pose of the fluoroscopic imaging device for each frame of the fluoroscopic video and to construct fluoroscopic-based three dimensional volumetric data of the target area in which soft tissue objects are visible using a fast iterative three dimensional construction algorithm.

A system and method are provided for performing fluoroscopic procedures with assistance of guiding laser beam projections to reduce a reliance on harmful radiation emitting fluoroscopic imaging devices during the procedure. The system and method reduce an amount of radiation exposure to patients and medical personnel during procedures that require assistive real-time imaging. Specifically, an automated laser guidance system and method of use is provided to reduce fluoroscopic radiation, reduce operation time, and increase operative accuracy.

Systems and methods for quantification of an influence of scattered radiation in the analysis of an object a projection image is provided. Based on the projection image and on a characteristic of a tomography facility and/or of the object relating to the influence of the scattered radiation, at least one intermediate image is created. The at least one intermediate image is analyzed using an artificial neural network to quantify the influence of the scattered radiation.

Disclosed is a C-shaped arm X-ray apparatus, comprising a C-shaped arm translation assembly (1), a support column (2), a base (3), a balancing weight (4) and an adjusting apparatus. One end of the support column (2) is connected to the base (3), and the other end of the support column is slidably connected to the C-shaped arm translation assembly (1). The balancing weight (4) is in sliding connection with the base (3). The adjusting apparatus is connected to the balancing weight (4), and when the C-shaped arm translation assembly (1) moves in a first direction, the adjusting apparatus enables the balancing weight (4) to move by a preset distance in the direction opposite to the first direction such that the gravity center of the C-shaped arm X-ray apparatus can be maintained at a preset position. The stability of the C-shaped arm X-ray apparatus can be guaranteed by adjusting the position of the balancing weight (4) by means of the adjusting apparatus.

An X-ray diagnosis apparatus according to an embodiment includes an X-ray limiter having four diaphragm blades; and a console on which four physical operating units that correspond to the four diaphragm blades are placed at four positions. When viewed from the side of the operator of the console, the four operating units are placed on the far side, the near side, the left side, and the right side. The far-side operating unit, the near-side operating unit, the left-side operating unit, and the right-side operating unit correspond to the upper diaphragm blade, the lower diaphragm blade, the left-side diaphragm blade, and the right-side diaphragm blade, respectively, with reference to an X-ray image displayed in a display. An operation of moving the far-side operating unit in the far-side direction results in the movement of the upper diaphragm blade in the upward direction of the X-ray image displayed in the display, and an operation of moving the far-side operating unit in the near-side direction results in the movement of the upper diaphragm blade in the downward direction of the X-ray image displayed in the display. An operation of moving the near-side operating unit in the far-side direction results in the movement of the lower diaphragm blade in the upward direction of the X-ray image displayed in the display, and an operation of moving the near-side operating unit in the near-side direction results in the movement of the lower diaphragm blade in the downward direction of the X-ray image displayed in the display. An operation of moving the left-side operating unit in the leftward direction results in the movement of the left-side diaphragm blade in the leftward direction of the X-ray image displayed in the display, and an operation of moving the left-side operating unit in the rightward direction results in the movement of the left-side diaphragm blade in the rightward direction of the X-ray image displayed in the display. An operation of moving the right-side operating unit in the leftward direction results in the movement of the right-side diaphragm blade in the leftward direction of the X-ray image displayed in the display, and an operation of moving the right-side operating unit in the rightward direction results in the movement of the right-side diaphragm blade in the rightward direction of the X-ray image displayed in the display.

A transformable imaging system configured to operate in at least two configurations. A first configuration may be open and a second configuration may be closed. The closed configuration may allow for imaging in along an arc greater than 180 degrees.

A method for calculating during use the geometric parameters of an x-ray imaging system, an object or a patient to be observed being placed between the x-ray source and a detector of x-rays having passed through the object or patient, wherein it includes at least the following steps: detecting at least one marker on the object or the patient or in proximity to the object, the marker being of unknown 3D position, acquiring a plurality of 2D images for a plurality of viewpoints of the imaging system, detecting the position of at least one marker in each of the acquired 2D images, estimating the projection matrices corresponding to the projections of the object at various viewing angles and reconstructing in 3D the position of a marker on the basis of the estimation of the projection matrices.
