Description

Respiratory Tunning Device {RESPIRATION TUNING DEVICE}

The present invention relates to a respiration synchronization device for linking a respiration monitoring device and an imaging device.

An imaging device using X-rays may transmit X-rays through the human body in order to photograph the inside of the human body. Specifically, X-rays have a property of easily passing through a material having a low density and not easily passing through a material having a high density. Therefore, in an X-ray image, regions composed of materials with high density (eg, organs, bones, and tumors) have high brightness, and regions composed of materials with low density (eg, fat, and muscle) may have a low brightness.

When taking X-rays of the abdomen and chest, the patient's breathing control is required. When the patient breathes during X-rays of the abdomen and chest, organs and muscles can move. Therefore, in order to provide accurate image information, the patient's breathing control is required. For this reason, in the field of X-ray imaging, an imaging technique for obtaining an accurate image of a patient's respiration is required.

An object of the present invention is to provide a respiration synchronization device for interlocking a respiration monitoring device for monitoring a patient's respiration state and outputting a gate signal and an imaging device using X-rays.

A respiratory synchronization device according to an embodiment of the present invention controls an imaging device in a recording standby mode in response to an output voltage received from the respiration monitoring device for monitoring a respiration state, and based on the monitored respiration state, provided from the respiration monitoring device and a first relay for outputting a gate signal and a second relay for controlling the imaging device in an imaging mode to perform X-ray imaging of the imaging device in response to the gate signal output from the first relay.

According to an embodiment of the present invention, the respiration synchronization device may control the imaging device so that accurate image data may be provided by interlocking the respiration monitoring device and the imaging device.

Referring to FIG. 1 , an X-ray imaging system 100 may include a respiration monitoring device 110, a switch 120, a respiration synchronization device 130, and an imaging device 140.

Respiration monitoring device 110 may monitor the patient's respiration. In some embodiments, the breathing monitoring device 110 may monitor the patient's breathing state through a breathing sensor (not shown) attached to the patient's abdomen.

As some embodiments, the respiration monitoring device 110 may be a Real Time Position Management (RPM) device. The marker can be used as an index to show the patient's respiratory rate. Respiration monitoring device 110 may detect the movement of a marker (marker (not shown)) attached to the patient's belly. The marker can move up and down according to the patient's breathing. In addition, the breathing monitoring device 110 may monitor the patient's breathing condition by detecting the movement of the indicator. Respiration monitoring device 110 may output a gate signal when the indicator goes below the reference point. Illustratively, when the indicator goes below the reference point, it may be the moment when the patient's lungs contain about 10% of air. Illustratively, the breathing monitoring device 110 may determine that the patient's breathing is stable when the marker goes below the reference point.

Respiration monitoring device 110 may apply an output voltage to the switch (120). Illustratively, the output voltage may be 5V. The output voltage may be used as a driving voltage of the respiratory synchronization device 130 through the switch 120. The output voltage applied to the switch 120 is described in detail with reference to FIGS. 3 and 4 .

The switch 120 may be connected between the respiration monitoring device 110 and the respiration synchronization device 130 . According to the operation of the switch 120, the output voltage of the respiration monitoring device 110 may be applied to the respiration synchronization device 130. The switch 120 may control the operation of the respiratory tuning device 130 by controlling the output voltage applied to the breathing tuning device 130 . The switch 120 for controlling the respiratory tuning device 130 will be described in detail with reference to FIGS. 3 and 4 .

The breathing synchronization device 130 may control the imaging device 140 in at least one of a shooting standby mode and a shooting mode. Specifically, when the respiratory synchronization device 130 receives the output voltage from the switch 120, the respiratory synchronization device 130 may control the imaging device 140 to a recording standby mode.

Then, when the recording standby mode, when the breathing tuning device 130 receives a gate signal from the breathing monitoring device 110, the breathing tuning device 130 may control the imaging device 140 to the shooting mode. In the photographing mode, the imaging device 140 may emit X-rays and may perform photographing using the X-rays. The imaging device 140 may provide accurate imaging result data to the user of the X-ray imaging system 100 by performing imaging under the control of the respiratory synchronization device 130 .

However, the present invention is not limited thereto, and the breathing synchronization device 130 may be included in at least one of the breathing monitoring device 110 and the imaging device 140 . Alternatively, the respiratory synchronization device 130 may be implemented as a single device separate from the respiratory monitoring device 110 and the imaging device 140 .

Figure 2 is a timing diagram for showing the signal output from the respiratory monitoring device. Referring to FIGS. 1 and 2 , the respiration monitoring device 110 may output a gate signal as shown in FIG. 2 . Specifically, the respiratory monitoring device 110 may measure and analyze the patient's respiratory state.

Referring to the graph shown in FIG. 2 , inhalation and exhalation of the patient may be repeatedly performed. When the patient's respiratory volume is below the stable criterion, the marker may drop below the reference point. Then, when the indicator goes below the reference point, the respiration monitoring device 110 may output a gate signal. Illustratively, when the marker goes below the reference point, the respiration monitoring device 100 may determine the most ideal state in imaging the tumor. Therefore, when the patient's breathing volume is below the stable criterion, the respiration monitoring device 100 may output a gate signal of a high state. Illustratively, the magnitude of the voltage of the high-state gate signal may be 5V. The gate signal may be used as a control signal for controlling the operation of the respiratory tuning device 130 . And, the breathing tuning device 130 may control the imaging device 140 in response to the control signal.
