Abstract: Interstitial brachytherapy is a cancer treatment in which radioactive material is placed closely to the target tissue of the affected site using an afterloader (HDR-brachytherapy) or manually (LDR- and PDR-brachytherapy). For HDR-brachytherapy, the accuracy of this placement is calibrated using an external reference system that locates the radioactive material according to the radiation levels measured at locations around the source. At each of these locations, a scintillator produces light when irradiated by the radioactive material. This light is proportional to the level of radiation at each location. The light produced by each scintillator is converted to an electrical signal that is proportional to the light and the radiation level at each location. The radioactive material is located according to the plurality of electrical signals.

Abstract: Methods and systems are provided for contrast-enhanced diagnostic imaging. In one embodiment, a method comprises estimating a time to perform a diagnostic scan of a patient based on demographics of the patient, and performing the diagnostic scan of the patient at the estimated time responsive to a confidence level of the estimated time above a threshold. In this way, a contrast-enhanced diagnostic scan may be performed without directly monitoring the contrast flow, thereby reducing radiation dose and contrast load while maintaining or improving image quality.

Abstract: An X-ray-diagnostic apparatus generates time-series first vessel images corresponding to a first direction, and generates second vessel image corresponding to a second direction. The apparatus generates third vessel images corresponding to the second direction, by transforming more than one piece out of the first vessel images based on a blood vessel shape in one of the first vessel images and a blood vessel shape in at least one of the second vessel image, the third vessel image corresponding to respective time phases of the first vessel images. The apparatus generates first color image corresponding to the first direction by using more than one piece out of the first vessel images, and generates second color image corresponding to the second direction by using more than one piece out of the third vessel images. The apparatus displays a stereoscopic image based on the first color-image and the second color image

Abstract: A patient placement table moving method may be used with a robotic operating table including a patient placement table, a base buried in or fixed to a floor and an articulated robotic arm including joints and having first and second ends. The first end may be supported on the base to be rotatable about an axis extending in a vertical direction. The second end may support the table. The method may include: horizontally arranging the table by the robotic arm at an imaging position for imaging with a medical imaging apparatus; and translating the table from the imaging position to a surgical operation position by the robotic arm. The surgical operation position may be away from the imaging position by 200 mm or more in a second direction orthogonal to a first direction in a horizontal plane, and the first direction is parallel with a longitudinal direction of the table.

Abstract: The present invention relates to a modulation of X-ray radiation for the purposes of imaging an object of interest. For the modulation, the X-ray radiation provided by an X-ray source (12) is in part totally reflected by a mirror (20). Thus, an X-ray radiation at an object receiving space (16) is formed by an unreflected X-ray radiation (24) and a reflected X-ray radiation (26). The mirror (20) is displaceable by an actuator (28), such that the intensity of the reflected X-ray radiation (26) can be adjusted, in particular to a density of the object to be imaged.
