A power supply for an x-ray emitter is disclosed. A voltage source of the power supply is configured to provide an acceleration voltage or a heating voltage between a first internal contact and a second internal contact to, in a first operating mode, supply the x-ray emitter with power. The power supply includes a control device configured, in a second operating mode, to detect a voltage between the first and the second internal contact and/or to detect a current via the first and/or second internal contact. As a function of the detected voltage and/or of the detected current, the control device is configured to activate a warning device for giving a warning and/or to transmit a warning signal. A method is further disclosed.

A phoswich device for determining depth of interaction (DOI) includes a first scintillator having a first scintillation decay time characteristic, a second scintillator having a second scintillation decay time characteristic substantially equal to the first scintillation decay time, a photodetector coupled to the second scintillator, and a wavelength shifting layer coupled between the first scintillator and the second scintillator, wherein the wavelength shifting layer modifies the first scintillation decay time characteristic of the first scintillator to enable the photodetector to differentiate between the first decay time characteristic and the second decay time characteristic. The phoswich device is particularly applicable to positron emission tomography (PET) applications.
