Patent number: 6714622Abstract: In a method and apparatus for producing an overall image from a number of partial images which are produced successively for common playback, a first partial image is produced and stored, and at least a portion of the first partial image, that adjoins a second partial image to be produced, is played back. A survey image is produced for the second partial image and this survey image is simultaneously played back with the first partial image, with overlapping regions adjoining each other. From this simultaneous playback, the correct orientation of the exposure region for the second partial image is selected, and the image acquisition device is correspondingly positioned and the second partial image is produced, The first and second partial images are then joined to form the overall image.Type: GrantFiled: July 19, 2002Date of Patent: March 30, 2004Assignee: Siemens AktiengesellschaftInventor: Heinz Horbaschek

Patent number: 6304627Abstract: Radiographic diagnostic device has a projection unit that is formed as a computer tomography system with a radiation emitter and a line detector, which are constructed such that they can be rotated around a projection area opposite one another. A support apparatus with a support plate for an examination subject is provided. The radiographic diagnostic device has an additional radiation receiver allocated to it so that the additional radiation receiver can be moved from a standby position into a pick-up position for receiving a radiation beam that emanates from the radiation emitter of the computed tomography system. Both computed tomography projections and conventional X-ray projections can be obtained with the radiographic diagnostic device when the additional radiation receiver is realized as a radiographic film, a solid-state detector, or a storage foil.Type: GrantFiled: April 25, 2000Date of Patent: October 16, 2001Assignee: Siemens AktiengesellschaftInventor: Heinz Horbaschek

Patent number: 5630414Abstract: An X-ray diagnostics installation has an X-ray source and an X-ray image intensifier video chain, including an X-ray image intensifier, a video camera, a control circuit that derives control pulses for producing images of a subject from data supplied thereto identifying exposure conditions, and a subtraction circuit for forming the difference between stored video signals and continuing, current video signals given the same exposure conditions. The X-ray source is cyclically moved during the production of a number of successive images, with the control circuit deriving the control pulses for the production of images from apparatus positions and, possibly, from the ECG of the subject. The subtraction circuit forms the difference between predetermined video signals stored for different apparatus positions and heart phases of a heart cycle and continuing, current video signals obtained at the same apparatus positions and at the same heart phase.Type: GrantFiled: March 17, 1995Date of Patent: May 20, 1997Assignee: Siemens AktiengesellschaftInventor: Heinz Horbaschek

Patent number: 5509044Abstract: A medical radiological diagnostics system having an automatic exposure unit employs signal acquisition and a processing circuitry for controlling the radiation source so as to obtain easily diagnosed exposures with a low radiation load. This is accomplished by disposing a stray radiation grid between the radiation receiver and a radiation sensor, or by selecting the spacing between the radiation receiver and the radiation sensor such that scattered radiation is not incident on the radiation sensor, or, in a system having an x-ray image intensifier and a light sensor, by supplying the output signal of the light sensor to the control circuit through a high-pass filter. In all versions, the measured signal is not disadvantageously influenced by scattered radiation, so that a correct exposure of x-ray film is possible.Type: GrantFiled: April 26, 1995Date of Patent: April 16, 1996Assignee: Siemens AktiengesellschaftInventor: Heinz Horbaschek

Patent number: 5495514Abstract: An x-ray diagnostics installation has an x-ray source connected to a parameter setting unit which sets exposure parameters (operating characteristics) of the x-ray source, and an x-ray image intensifier video chain. The x-ray image intensifier video chain includes a processing circuit connected to a video pick-up stage and a motion detector. The processing unit controls the parameters of a filter unit for chronological filtering of the video signal. The motion detector is connected to the parameter setting unit for the x-ray source, and controls the filter unit depending on the exposure parameters which are set for a given exposure, such as the level of the video signal, the tube voltage, the radiation dose, and the imaging format of the x-ray image intensifier, all of which are set at the parameter setting unit and which characterize the exposure.Type: GrantFiled: December 12, 1994Date of Patent: February 27, 1996Assignee: Siemens AktiengesellschaftInventors: Heinz Horbaschek, Heinz Eschenbacher
