Radiation image acquisition device

An apparatus for capturing a radiation image, the apparatus comprising:

• a radiation source configured to emit radiation;
• a wavelength converter having an entrance plane, wherein the wavelength converter is configured to receive the radiation emitted from the radiation source through the entrance plane after the emitted radiation has been transmitted by an object, to convert the received radiation to scintillation light, and to output the scintillation light from the entrance plane;
• a first optical system including at least one lens, the first optical system being configured to focus on the entrance plane and to image the output scintillation light, thereby generating a first radiation image of the object;
• and
• a first image sensor configured to capture the first radiation image.

A method for capturing a radiation image, the method comprising:

• emitting radiation from a radiation source;
• converting the radiation emitted from the radiation source to scintillation light after the emitted radiation has been transmitted by an object, wherein the converting is performed using a wavelength converter having an entrance plane;
• outputting the scintillation light from the entrance plane;
• imaging the output scintillation light, thereby generating a first radiation image of the object, using a first optical system that is focused on the entrance plane;
• and
• capturing the first radiation image.
