Abstract
For performing imaging with a high-frame rate, a control apparatus determines the time where at least one electrical charge of a sensor is read based on information about the position of an irradiation area of the sensor, the irradiation area being irradiated with a radiation, so that the time period where at least one electrical charge of a non-irradiation area of the sensor is read, the non-irradiation area being irradiated with no radiation, overlaps the time period where irradiation with the radiation is performed and the time period where at least one electrical charge of the irradiation area of the sensor is read does not overlap the radiation-irradiation-time period.
Claims10
A control apparatus for controlling a sensor which detects radiation from a radiation-generation device and generates an electrical charge based on the detected radiation, the control apparatus comprising:
- a determination unit configured to determine a time when at least one electrical charge of the sensor is read based on information about a position of an irradiation area of the sensor, the irradiation area being an area of the sensor irradiated with the radiation, so that a time period during which at least one electrical charge of a non-irradiation area of the sensor is read, the non-irradiation area being an area of the sensor not being irradiated with radiation, overlaps an irradiation time period during which irradiation of the irradiation area with the radiation is performed, and so that a time period where at least one electrical charge of the irradiation area of the sensor is read does not overlap the irradiation-time period;
- and
- a control unit configured to control reading of the electrical charge of the sensor based on the time at which the electrical charge of the sensor is read, the time being determined by the determination unit.
A control method for controlling a sensor which detects radiation from a radiation-generation unit and generates an electrical charge based on the detected radiation, the control method comprising:
- determining a time when at least one electrical charge of the sensor is read based on information about a position of an irradiation area of the sensor, the irradiation area being an area of the sensor irradiated with the radiation, so that a time period during which at least one electrical charge of a non-irradiation area of the sensor is read, the non-irradiation area being an area of the sensor not being irradiated with radiation, overlaps an irradiation time period during which irradiation of the irradiation area with the radiation is performed, and so that a time period where at least one electrical charge of the irradiation area of the sensor is read does not overlap the irradiation-time period;
- and
- controlling reading of the electrical charge of the sensor based on the time at which the electrical charge of the sensor is read, the time being determined at the determination step.
A computer-readable storage medium storing a program making a computer execute a control method for controlling a sensor which detects a radiation from a radiation-generation unit and generates an electrical charge based on the detected radiation, the control method comprising:
- determining a time when at least one electrical charge of the sensor is read based on information about a position of an irradiation area of the sensor, the irradiation area being an area of the sensor irradiated with the radiation, so that a time period during which at least one electrical charge of a non-irradiation area of the sensor is read, the non-irradiation area being an area of the sensor not being irradiated with radiation, overlaps a time period during which irradiation of the irradiated area with the radiation is performed, and a time period where at least one electrical charge of the irradiation area of the sensor is read does not overlap the irradiation-time period;
- and
- controlling reading of the electrical charge of the sensor based on the time at which the electrical charge of the sensor is read, the time being determined at the determination step.
