An x-ray diagnostic apparatus and methods performs Real-Time Digital Radiography with particular application in dental x-ray imaging modalities, such as Orthopantomography, Scannography, Linear Tomography and Cephalography, by using a versatile and modular electronic unit, featuring ultra fast computation capability to serve diversified image sensor typology and scanning modality.

In Digital Orthopantomography and Scannography, a plurality of tomographic images at different depths of the jaw can be generated, based on the pre-selection made by the user interface.

The image processing unit utilizes for the tomo-synthesis of the diagnostic image an accurate and economic digital simulator of the radiographic film speed, including a digital frequency synthesizer fed with film cassette speed digital input and high resolution clock signal, ensuring accurate and reproducible phase continuity of the output frequency signal.

It also introduces an automatic adaptation of the frame acquisition rate in frame transfer mode, based on the actual speed of the cassette unit. By this method the dynamic of the exposure signal is reduced, and a better optimization of the signal response of the x-ray detector is achieved.

In a heat storage system for a vehicle, when a temperature of cooling water from a vehicle engine is high, adsorbents are heated by the cooling water, so that moisture is desorbed from the adsorbents in order to store heat. When the temperature of cooling water is low, the moisture is adsorbed in the adsorbents to heat the cooling water, while refrigerant in a vapor compression refrigerator is cooled by evaporating water. Thus, adsorption heat is generated from the adsorbents, and the cooling water is heated by using the adsorption heat. Accordingly, warm-up operation of the vehicle engine is facilitated, while motive power consumed by the vapor compression refrigerator can be reduced.

Electron linear accelerators are used to generate X-ray radiation for the treatment of tumors. Efficient irradiation of tumors can only be guaranteed if the electron beam is guided accurately and so the required dose profile is applied. The deviation from the ideal path of the electron beam is measured by means of so-called beam position monitors and then corrected by magnets.

According to the invention the deviation of the electron beam is measured in a drift tube of the linear accelerator, the wave to be decoupled having a frequency range that corresponds to a multiple of the basic frequency of the acceleration field. Coupling probes, a mixer-based receiving concept with high dynamics and sensitivity, a method for evaluating the measuring signals and a calibration method for calibrating out non-linearities are specified.

Disruptive influences through the acceleration field are minimized by the measurement method according to the invention and the frequency range to be evaluated. The high evaluated frequencies also offer geometrically small coupling probes which one can introduce into a drift tube in which only the field of the electron beam to be evaluated exists.
