Radiological imaging apparatus

A radiological imaging apparatus comprising:

• a semiconductor radiation detector that detects a radiation;
• a capacitor that applies a voltage to the detector;
• a first current regulated unit that conducts a charge current to the capacitor;
• a second current regulated unit that conducts a discharge current from the capacitor;
• and
• an opening and closing unit having the first current regulated unit and the second current regulated unit connected to an input end.

A radiological imaging apparatus comprising:

• a bed that supports a subject and;
• a semiconductor radiation detector that detects a radiation from the subject,
• the radiological imaging apparatus intermittently moving the bed to detect the radiation,
• the radiological imaging apparatus further comprising:
• a capacitor that applies a voltage to the detector;
• and
• a unit that subjects the capacitor to charging or discharging in synchronism with the intermittent movement of the bed.

A radiological imaging apparatus comprising:

• a semiconductor radiation detector that detects a radiation;
• a capacitor that applies a voltage to the detector;
• a first resistor that conducts a charge current to and a discharge current from the capacitor;
• a second resistor connected in parallel with the first resistor to subject the capacitor to charging and discharging;
• a first opening and closing unit connected in series with the second resistor;
• and
• a second opening and closing unit connected to a wire connecting the first resistor and the first opening and closing unit together.
