X-ray detector and operation method thereof
The present disclosure is for minimizing the problem of AED sensor malfunction, and comprises: a panel having a plurality of sensing elements for sensing an X-ray, and converting an X-ray into an electrical signal; an AED sensor for sensing an X-ray; and a main control unit for obtaining image data by reading out the charge of the panel when an X-ray is sensed by the AED sensor, wherein the main control unit may determine whether or not reading out is to be performed on the basis of the acceleration of the panel even when the AED sensor senses an X-ray.
1 . A detector comprising:
a panel comprising a plurality of sensors including a scintillator and an automatic exposure detection (AED) sensor capable of detecting X-rays and configured to convert X-rays into an electrical signal;
an acceleration sensor configured to detect the acceleration of the panel;
control circuitry including a trigger signal determination unit configured to generate a trigger signal based on a first sensor value of the AED sensor and a second sensor value of the acceleration sensor; and
a main controller configured to read-out charges of the panel to obtain image data based on the generated trigger signal,
wherein the trigger signal determination unit is configured to:
obtain the first sensor value of the AED sensor and the second sensor value of the acceleration sensor,
determine whether the first sensor value of the AED sensor is greater than a first threshold value,
determine whether the second sensor value of the acceleration sensor is greater than a second threshold value when the first sensor value of the AED sensor is greater than the first threshold value, and
generate the trigger signal when the second sensor value of the acceleration sensor is less than or equal to the second threshold value,
wherein the main controller does not perform read-out and determines that sensing of the AED sensor is misdetection, when the first sensor value of the AED sensor exceeds the first threshold value and the second sensor value of the acceleration sensor exceeds the second threshold value.
2 . The detector of claim 1 , wherein the main controller is configured to output a notification informing about a shock of the detector based on the detected acceleration of the panel.
3 . The detector of claim 1 , wherein the main controller is configured to perform the read-out based on the first sensor value of the AED sensor exceeding the first threshold value and the second sensor value of the acceleration sensor being less than or equal to the second threshold value.
4 . The detector of claim 3 , wherein the trigger signal determination unit is configured to generate the trigger signal for performing the read-out further based on the sensor value of the AED sensor exceeding the first threshold value.
5 . The detector of claim 3 , wherein the main controller is configured to store image data resulting from the read-out in a memory based on detection of an object in the resulting image data.
6 . The detector of claim 3 , wherein the main controller is configured to not store the image data in the memory based on no objects being detected in the resulting image data.
