Method for correction of artifacts arising from temporal changes of attenuation values

Номер: US20120051619A1
Автор: Andreas Fieselmann, Frank Dennerlein
Принадлежит: SIEMENS AG

A method for correcting artifacts in an image dataset reconstructed by filtered back projection is proposed. The artifacts are occurred as a result of temporal changes of attenuation values during rotational recording of X-ray projection images with an angular speed. A linear, analytically-derived, filter-type relationship between the attenuation values of the image dataset at a reference point and the real attenuation values is determined from the sum of a respective application of an angle speed-dependent weighting factor, a point spread function and a temporal derivation, evaluated at the reference time. The linear relationship is inverted and the inverted linear relationship is applied to the attenuation values of the image dataset for the correction.

When a multi-system setting command switch, targeted rotating position information switches, and a command executing switch are pressed down, a CPU reads out a path of frontal and lateral systems from a current position to a setting position from a setting position information memory, and reads out rotation direction and angle from a targeted position information memory. The CPU moves the frontal and lateral systems horizontally along the read-out path until the commanded setting position information conforms to detected actual position information. When the setting position information conforms to the actual position information, the frontal and lateral systems are rotated successively until the commanded rotation direction and angle conform to the detected actual position information. Thereby a fluoroscopic X-ray system can be moved smoothly from a standby position via the setting position to a targeted rotating position.

A method of operating an x-ray unit that supplies the maximum power at all times, for which the supply or input voltage at the x-ray tube must be half the power supply voltage ((Vbat)/2 or (Vline)/2), which will be termed the reference voltage (Vref). In case of a deviation from the reference voltage, the method modifies the current supplied, changing the exposure time so that the maximum power is delivered at all times. In short, it is based on a method that regulates the tube current as a function of the supply voltage (of the batteries or the grid). 1. A method for automatic maximum power regulation in x-ray units , comprising:calculating a reference voltage (Vref), which if the x-ray unit is powered by a grid will be half of a line voltage (V line), provided this value is greater than 90 volts, and otherwise the reference voltage will be 90 volts, and if the x-ray unit is battery powered the reference voltage will be half of a voltage supplied by batteries (Vbat);comparing the reference voltage (Vref) and an input voltage (Vi) supplied to the x-ray unit, regulating the voltage and thereby the power, and obtaining a reference for a current to supply (Iref); andcomparing the reference current (Iref) to the input current (Ii) to obtain a filament current (Ifil), which is the current that allows supplying the maximum power at all times and corresponds to the regulated voltage of the input voltage having as reference, the reference (Vref) which is half of the line voltage (V line), provided this value is greater than 90 volts, and otherwise the reference voltage will be 90 volts, and if it is battery powered the reference voltage will be half of the voltage supplied by the batteries (V bat).2.

One or more techniques and/or systems described herein implement, among other things, a parabolic curve for a ramp signal in a data acquisition component, where the curve can be effectively calibrated and used to provide a settling period to mitigate noise. That is, a ramp generator can generate a ramp signal that has a parabolic voltage curve with two substantially mirroring halves. A comparator can compare a first portion of the parabolic voltage curve with a voltage signal indicative of a number of photons detected by a detection array. A second portion of the parabolic voltage curve is used as a temporal delay so that circuitry, such as the ramp generator, can settle.

An x-ray source can include a power supply and an x-ray tube. The power supply can include digital-to-analog converters (DACs) electrically-coupled between a digital controller and an x-ray tube control circuit. A user of the x-ray source can provide a digital input to the digital controller for operation of the x-ray source. Advantages of this power supply can include easy operation of the x-ray source, minimize problems in x-ray source operation due to variation between manufactured x-ray tubes, and reduced electronic noise. There can be a small distance between the DACs and the x-ray tube control circuit. The power supply electronic components can be part of a single electronic circuit rigidly-mounted together. The digital controller, the first DAC, the second DAC, and the x-ray tube control circuit can be rigidly-mounted within a housing. 1. A power supply for an x-ray tube , the power supply comprising:a) a digital controller capable of emitting a first digital signal to indicate a desired x-ray tube voltage and a second digital signal to indicate a desired x-ray tube electrical current for an electron emitter;b) a first digital-to-analog converter, defining a first DAC, electrically-coupled to the digital controller, capable of receiving the first digital signal, and capable of emitting a voltage corresponding to the first digital signal, defining a first analog signal;c) a second digital-to-analog converter, defining a second DAC, electrically-coupled to the digital controller, capable of receiving the second digital signal, and capable of emitting a voltage corresponding to the second digital signal, defining a second analog signal; i) electrically-coupled to the first DAC and capable of receiving the first analog signal and providing a voltage differential, of at least 1 kilovolt, to the x-ray tube, based on the first analog signal;', 'ii) electrically-coupled to the second DAC and capable of receiving the second analog signal and providing an electrical ...

A method for processing angiography image data by using an imaging catheter path that is directly detected from the angiography data as a co-registration path or using detected marker locations from the angiography data to generate a co-registration path. If the acquired angiography data includes synchronized cardiac phase signals and a predetermined quantity of angiography image frames not including contrast media, then a directly detected imaging catheter path is used as the co-registration path. Otherwise the co-registration path is determined based upon detected marker locations from the angiography image data. 1. A method for processing angiography image data , the method comprising:an importing step for importing angiography data including a plurality of angiography image frames, the angiography data being synchronized with cardiac phase signals such that each angiography image frame includes an associated cardiac phase signal;a first detecting step for detecting an imaging catheter path for angiography image frames not including contrast media in a targeted area and saving the imaging catheter path with the associated cardiac phase signal for the angiography image frames not including contrast media in the targeted area;a second detecting step for detecting a vessel contour and a marker for angiography image frames including contrast media in the targeted area and saving the vessel contour, the marker and the associated cardiac phase signal for the angiography image frames including contrast media in the targeted area;a selecting step for selecting an angiography image frame from the angiography image frames including contrast media and selecting an angiography image frame from the angiography image frames not including contrast media having identical cardiac phase signals;an overlaying step for overlaying the angiography image frame from the angiography image frames including contrast media with the angiography image frame from the angiography image frames ...
