Abstract

In an image collecting system for sensing an X-ray image by using a solid state image pickup unit, the operability of the system is improved by omitting an operation of turning on and off the solid state image pickup unit or other operations. When an operator selects an image sensing part of an object by using an acquisition part setting button on a display unit, the solid state image pickup unit is driven and a timer starts, and in addition, the sensing condition, image processing parameters and the like are automatically set in accordance with the selected sensing part. When an exposure button is depressed before the timer counts up, e.g., in 10 minutes, an X-ray generation control unit makes an X-ray tube radiate an X-ray to the object, and the solid state image pickup unit senses an X-ray image. If the exposure button is not depressed in 10 minutes, the operation of the solid state image pickup unit is stopped and the set sensing part is released.

Claims

1. A system comprising:

X-ray irradiating means for irradiating an X-ray;

an image pickup unit for acquiring an image of an object by receiving the X-ray which has been irradiated onto the object and transmitted through the object;

an input unit for inputting information

a first control unit for changing a state of said image pickup unit between an active state and an inactive state in accordance with the information from said input unit; and

a second control unit for determining the state of said image pickup unit on the basis of a drive notification signal from said image pickup unit, and for sending an irradiation permission signal to said X-ray irradiating means when said image pickup unit is determined to be in the active state.

2. A system according to claim 1, wherein the input information comprises information identifying an image of the object to be acquired by said image pickup unit.

3. A system according to claim 2, wherein the identifying information comprises information specifying the object.

4. A system according to claim 1, further comprising a request reception unit for receiving an image acquisition request from an external source, wherein the image acquisition request includes information specifying a kind of one or more images of the object to be acquired.

5. A system according to claim 4, wherein said input unit comprises a kind of selection unit for selecting a kind of an image to be acquired in accordance with the image acquisition request received by said reception unit.

6. A system according to claim 1, wherein said first control unit changes the state of said image pickup unit into the inactive state if image sensing by said image pickup unit is not performed for a predetermined time after the information has been input from said input unit.

7. A system according to claim 6, further comprising a display unit for displaying a notice of a lapse of the predetermined time.

8. A system according to claim 6, wherein said first control unit releases the information if image sensing by said image pickup unit is not performed for a predetermined time after the information has been input from said input unit.

9. A system according to claim 1, wherein said first control unit changes the state of said image pickup unit into the active state if the information is input from said input unit.

10. A system according to claim 9, further comprising a display unit for displaying a notice that said image pickup unit, when in the active state, is in an image acquisition-enabled state.

11. A system according to claim 4, wherein said first control unit changes the state of said image pickup unit into the inactive state if the image acquisition request for which an image acquisition is not completed is empty after an image is acquired.

12. A system according to claim 1, wherein said system is adapted to acquire an X-ray image.

13. A system according to claim 12, further comprising a condition reception unit for receiving X-ray condition information from an X-ray generation apparatus controller, wherein said first control unit changes the state of said image pickup unit into the active state in accordance with a reception of the X-ray condition information.

14. A system according to claim 12, further comprising a condition reception unit for receiving X-ray condition information from an X-ray generation apparatus controller and a setting unit for setting a grid speed parameter in accordance with the X-ray condition information.

15. A method adapted to an imaging system, the method comprising the steps of:

inputting information from an input unit;

changing, with a first control unit, a state of an image pickup unit between an active state and an inactive state in accordance with an input of information from the input unit;

determining, with a second control unit, the state of the image pickup unit on the basis of a drive notification signal from the image pickup unit, and sending an irradiation permission signal to X-ray irradiation means when the image pickup unit is determined to be in the active state;

irradiating an object with an X-ray with the X-ray irradiation means when the irradiation permission signal is received by the X-ray irradiation means; and

acquiring an image of the object with the image pickup unit.

16. A computer-readable storage medium storing a program code for performing a method adapted to an imaging system, the method comprising the steps of:

inputting information from an input unit;

changing, with a first control unit, a state of an image pickup unit between an active state and an inactive state in accordance with an input of information from the input unit;

determining, with a second control unit, the state of the image pickup unit on the basis of a drive notification signal from the image pickup unit, and sending an irradiation permission signal to X-ray irradiation means when the image pickup unit is determined to be in the active state;

irradiating an object with an X-ray with the X-ray irradiation means when the irradiation permission signal is received by the X-ray irradiation means; and

acquiring an image of the object with the image pickup unit.

17. A system comprising:

X-ray irradiating means for irradiating an X-ray;

an image pickup unit for acquiring an image of an object by receiving the X-ray which has been irradiated onto the object and transmitted through the object;

an input unit for inputting information identifying an image of the object to be acquired by said image pickup unit;

a first control unit for changing a state of said image pickup unit between an active and an inactive state in accordance with the information from said input unit; and

a second control unit for determining the state of said image pickup unit on the basis of a drive notification signal from said image pickup unit, and for sending an irradiation permission signal to said X-ray irradiating means when said image pickup unit is determined to be in the active state.
