A method for planning a root canal treatment of a tooth which includes a cavity of a patient. The method includes measuring a surface of the cavity with an optical three-dimensional method to generate three-dimensional measurement data of the cavity. A 3D-model of a guide template is planned based on the generated three-dimensional measurement data. The 3-D model is designed in its dimensions as a counterpart to the cavity. Three-dimensional volume data of the tooth is displayed. A position and an orientation of a root canal of the tooth is determined based on the three-dimensional volume data of the tooth. A guide opening for a tool is planned to expose the root canal. The guide opening is arranged within the guide template so that the guide opening points at an entry point of the root canal and in an entry direction of the root canal.

A method for generating a virtual jaw image includes performing a movement recording method to obtain a movement record which comprises producing at least one position data record over a defined time. A position data record describes a spatial position of a lower jaw to an upper jaw at a specific time. Surface sections of the upper and lower jaw are scanned at the defined time during the movement recording method to obtain a spatial relation of the surface sections during the defined time. Digital upper and lower jaw images are recorded. A position data record of a virtual position of the digital lower jaw image is assigned to the digital upper jaw image. A position data record is selected to obtain a selected position data record. The digital lower and upper jaw images are virtually aligned based on the selected position data record to produce the virtual jaw image.

A patient table for a medical radiation therapy system or radiation diagnosis system is provided. The patient table includes a flat bearing surface and a surface-specific radiation absorption that is measured per radiated surface unit of the bearing surface. The perpendicular incidence radiation reduces along a transversal direction from a central longitudinal plane of the patient table to both of the lateral edges.

Use of an adaptive radiation therapy framework includes determination of a radiation beam size, radiation beam shape, and radiation beam position for delivering at least a portion of a prescribed radiation dose to a target volume based on first image data of a patient, and selection of one radiation therapy process from an available first process and second process. The first radiation therapy process comprises acquisition of two dimensional image data of the patient, determination of a position offset based on the two-dimensional image data and on the first image data, and movement of the patient based on the position offset. The second radiation therapy process comprises acquisition of three-dimensional image data of the patient, determination of a second position offset based on the three-dimensional image data and on the first image data, and movement of the patient based on the second position offset.

System and method utilizing adaptive radiation therapy framework

In a system and a method for generating an image dataset that contains superimposed or fused image data, a first system for the acquisition of a first image dataset of a subject and a second system for the acquisition of a second image dataset of the subject are provided that are different from each other. With a navigation system, the positions of the first and the second systems in the acquisition of the image datasets are determined, with reference to which the attitudes of the two image datasets in space can be determined, so that the two image datasets can be superimposed on one another or fused with one another.

The invention is directed to a mobile X-ray apparatus having an X-ray system comprising an X-ray source and an X-ray detector that is arranged at a carrier device. For registering a series of 2D projections of a subject, the carrier device is pivotable under motor drive around an axis that proceeds at least essentially horizontally through the carrier device. The X-ray apparatus comprises means for generating a 3D image dataset from the registered 2D projections. The invention is also directed to a method for determining the projection geometries required for producing a 3D image dataset from registered 2D projections.

A medical apparatus has a carrying device for at least one component, wherein the carrying device is adjustable relative to a holding mechanism and is formed of plastic. Rollers at least partly formed of plastic are provided for the adjustment of the carrying device relative to the holding mechanism, the carrying device being seated on these rollers and these rollers running directly on a plastic surface of the carrying device.

An x-ray system which can be operated at various energy supply sources which can respectively deliver different average electric powers per unit of time, has an x-ray source supplied by a voltage generator, an x-ray receiver and a control unit to which the average electrical power to be drawn from the respective energy supply source can be prescribed. The control unit actuates the voltage generator so that, given the prescribed available average electrical power per unit of time, x-ray pulses can be generated with a period, an x-ray energy and a pulse repetition rate so that x-ray images of moving objects can be acquired in cine mode, with the average electrical power per unit of time drawn from the respective energy supply source not being exceeded, and with at least the x-ray energy or the pulse period or the pulse repetition rate of the x-ray pulse to be generated being prescribed.

X-ray apparatus with a ceiling suspension has a motor for displacing and positioning the X-ray apparatus and a motion control circuit which superimposes a dynamic motion factor on the motor output so that pendulum motions during an acceleration of the apparatus are counteracted. For this purpose, a filter is connected in the motion control circuit in front of the setting element of the motor, the filter being dimensioned so as to correspond to the characteristic system behavior, and compensates oscillations of the apparatus.
