Embodiment 1

[0052] This embodiment provides a detection device, the detection device at least includes: a TFT panel 1 , a detection unit 2 and a circuit board 3 .

[0053] like figure 1 As shown, the circuit board 3 is disposed on the backlight surface of the TFT panel 1 .

[0054] like figure 1 As shown, the TFT panel 1 is used to respond to X-rays and convert the X-rays into charge signals. There are multiple pixels and driving lines in the TFT panel; as an example, each pixel contains 1 photodiode (Diode) and 1 thin film transistor (TFT), the photodiode can store the amount of charge corresponding to the X-ray dose, and the thin film The transistor is equivalent to a switch that stores charge in a photodiode. The switch can be turned on or off under the control of a drive circuit and timing. When turned on, the amount of charge stored in the Diode can be read. The TFT and Diode in the TFT panel will generate leakage current, which will gradually increase with the accumulation of tim...

Embodiment 2

[0067] This embodiment provides an X-ray imaging system, including the detection device described in the first embodiment, and also includes a computer and an X-ray source.

[0068] The detection device and the X-ray source are both connected to the computer, the computer triggers the X-ray source to emit X-rays, and the detection device collects X-ray images and transmits the collected X-ray images to the computer for processing. processing and display. When the detection device does not enter the detection area, the X-ray photography system is in a low power consumption state; when the detection device detects that the detected object enters the detection area, the X-ray photography system switches to normal working status.

[0069] In this embodiment, the detection device in the X-ray imaging system detects whether the object to be measured is in the detection area, so as to switch the working state of the X-ray imaging system. In the low power consumption state, the power...

Embodiment 3

[0071] This embodiment provides a low power consumption detection method, which is implemented based on the detection device in Embodiment 1, and includes the following steps:

[0072] Based on the detection unit 2, it is detected whether the detected object is in the detection area.

[0073] Specifically, when the detection unit 2 detects that the measured object enters the detection area, it sends a response signal to the circuit board 3. The detection methods include, but are not limited to, the detection device feels the pressure transmitted by the measured object, and the visual sensor Detecting the measured object and sensing the measured object through the proximity sensor, etc., will not be described in detail.

[0074] When the detected object is not detected to enter the detection area, the detection device switches to a low power consumption state.

[0075] Specifically, when the detection device is in a low power consumption state, the TFT panel 1 and the circuit ...

Abstract

The invention provides a detection device, an X-ray photography system and a low-power-consumption detection method. The detection device at least comprises a TFT panel, a detection unit and a circuit board. The TFT panel is used for responding to X-rays and converting the X-rays into charge signals; the detection unit is used for detecting whether a detected object exists in a detection area or not; and the circuit board is connected with the output end of the detection unit, and controls the TFT panel to be in a low power consumption state or a normal working state based on an output signal of the detection unit. The detection unit in the detection device sends the response signal when detecting the detected object, so that the detection device enters an exposure acquisition state, and is in a dormant non-working state when not detecting the detected object, the emptying frequency of a TFT panel is reduced, the power consumption is reduced, and the endurance time is prolonged.

Description

technical field [0001] The invention relates to the field of X-ray detection, in particular to a detection device, an X-ray photography system and a low-power consumption detection method. Background technique [0002] The existing wireless flat panel detector is powered by a battery and transmits signals wirelessly, and has good portability. Usually wireless flat panel detectors and mobile X-ray machines form a mobile DR (digital radiographic, direct digital X-ray photography) system, which is widely used in orthopaedics, emergency rooms, field battles and other scenarios to provide fast and effective imaging inspections for patients who are inconvenient to transport. , which is conducive to follow-up first aid and treatment. The battery life of the wireless flat panel detector refers to the longest time that a single battery can support the detector to work under the condition of full power, which is an important technical indicator of the detector. For the wireless flat...
