Abstract
The present invention relates to a solid-state X-ray detector comprising a photosensitive sensor associated with a radiation converter, known as a scintillator, transforming the X-rays into a radiation to which the sensor is sensitive, and an entry window through which the X-rays pass upstream of the scintillator. The entry window is mounted on the scintillator, without being fixed to the scintillator, and the entry window and the sensor are fixed by a water vapor-tight seal. The scintillator consists of a support, distinct from the sensor, and a scintillating substance. The application areas of this type of detector are notably radiology (radiography, fluoroscopy and mammography), but equally, non-destructive testing.
Claims18
A solid-state X-ray detector, comprising:
- a photosensitive sensor
- a scintillator transforming X-rays into a radiation to which the sensor is sensitive, the scintillator including a support and a scintillating substance;
- the scintillating substance being deposited on a support through which the radiation to be detected must pass before reaching the sensor;
- an entry window though which the X-rays pass upstream of the scintillator, such that the support is positioned between the entry window and the scintillating substance;
- and a water vapor-tight seal attached to said photosensitive sensor and to said entry window and spaced from said scintillator, support and scintillator substance;
- wherein the entry window is adjacent to the scintillator, without being fixed to the scintillator, the entry window and the sensor being fixed by the water vapor-tight seal, the support being distinct from the sensor.
The X-ray detector as claimed in 1, where in the scintillator comprises a material belonging to the family of alkaline halides or of rare earth oxysulfides.
