<p>A radiological apparatus having an X-ray tube (2) with control grid (17), a high-voltage generator (3) for electrically supplying the X-ray tube (2) so as to generate an X-ray beam (4), an X-ray detector (5), which consists of a CMOS flat panel with direct deposition of a scintillator and is arranged in front of the X-ray tube (2) to receive the X-ray beam (4) and form images of a patient (6) positioned between the X-ray tube (2) and the X-ray detector (5), a control unit (18) for generating a modulated control signal (CS) with a sequence of pulses (P), and a driving unit (19) connected between the control unit (18) and the grid (17) of the X-ray tube (2) for driving the grid (17) according to the control signal (CS) so that the X-ray beam (4) is intermittently generated and the X-ray detector (5) forms a respective image for each of said pulses (P).</p> |
