RADIATION IMAGING APPARATUS, RADIATION IMAGING SYSTEM, CONTROL METHOD FOR RADIATION IMAGING APPARATUS, NON-TRANSITORY COMPUTER-READABLE STORAGE MEDIUM, AND SIGNAL PROCESSING APPARATUS - A simplified explanation of the abstract
This abstract first appeared for US patent application 18317173 titled 'RADIATION IMAGING APPARATUS, RADIATION IMAGING SYSTEM, CONTROL METHOD FOR RADIATION IMAGING APPARATUS, NON-TRANSITORY COMPUTER-READABLE STORAGE MEDIUM, AND SIGNAL PROCESSING APPARATUS
Simplified Explanation
The patent application describes a radiation imaging apparatus that includes pixels with conversion and switch elements, a signal line, a readout circuit, and a processor. The readout circuit performs two operations during radiation exposure - reading out a signal when the switch element of each pixel is in a non-conduction state and reading out a signal when the switch element of a specific pixel is in a conduction state. The processor corrects the second signal value using the first signal value.
- The radiation imaging apparatus includes pixels with conversion and switch elements.
- A signal line is used to supply signals from the pixels.
- A readout circuit reads out signals from the signal line.
- The readout circuit performs two operations - reading out signals with switch elements in a non-conduction state and in a conduction state.
- A processor corrects the second signal value using the first signal value.
Potential Applications
- Medical imaging devices, such as X-ray machines and CT scanners.
- Industrial inspection systems for detecting defects or analyzing materials.
- Security scanners for screening baggage or cargo.
Problems Solved
- Improved image quality by correcting signal values.
- Efficient use of the readout circuit by performing different operations.
- Enhanced accuracy in radiation imaging.
Benefits
- Higher quality and more accurate radiation images.
- Increased efficiency in reading out signals.
- Improved performance and reliability of radiation imaging devices.
Original Abstract Submitted
A radiation imaging apparatus including pixels each including a conversion element and a switch element, a signal line to which signals are supplied from the pixels, a readout circuit reading out a signal supplied to the signal line and a processor processing a signal read out by the readout circuit, is provided. The readout circuit performs, during irradiation with radiation, a first operation of reading out a signal while the switch element of each of the pixels is in a non-conduction state and a second operation of reading out a signal while the switch element of a predetermined pixel of the pixels is in a conduction state. The processor corrects a second signal value of a signal read out by the second operation by using a first signal value of a signal read out by the first operation.
