Problems solved by technology

However, compensation cannot take into account changes in the x-ray generator, e.g. due to use, and often time-consuming recalibration of the equipment is required to compensate for such changes
[0007] Additionally, such inaccuracies are more difficult to predict and may require compensation for settings of the x-ray system outside of the optimum setting values ​​to achieve improved accuracy

Abstract

A method is provided for compensating the settings of a pulsed X-ray system. A current, voltage and intended pulse width settings are selected for the X-ray pulses to be provided. Then, the selected pulse width setting for the set voltage and tube current is compensated, in accordance with stored normalized value or values at a predetermined temperature, taking into account the environmental temperature of the electric circuitry of the X-ray tank. The normalized values are obtained in a calibration step from the actual or effective pulse width and the difference thereof with the intended width, normalizing said value with the temperature of the circuitry providing pulsed voltage and current to the source.

Description

technical field [0001] The invention relates to the field of radiodiagnosis. More particularly, the present invention relates to methods, software products and systems for generating X-ray pulses, activating and calibrating X-ray systems, and related calibrated X-ray systems. Background technique [0002] In an x-ray machine, several different x-ray patterns can be generated. Certain x-ray patterns are more advantageous than others depending on the application, surgeon, type of surgery, and / or components used in the x-ray machine. One possible X-ray pattern is a pulsed pattern, in which the X-rays are generated with a predetermined duty cycle. [0003] According to international regulations, the applied X-ray parameters should be reported to the user within a defined accuracy. In particular, for many applications, including medical and surgical applications, the expected average tube current should be accurate within 20% of the current actually applied to the tube for any...
