Description

Motion Phantom {MOTION PHANTOM}

The present invention relates to a motion phantom implemented as a motion using a motor as a motion of a lung, and more particularly, to a lung model in which a motion of a lesion cell model has a displacement similar to a behavior of a target cell The motion phantom.

Since the concept of radiation therapy is not long, there are problems even though radiation therapy is currently introduced. First, because it is a field that needs to be continuously developed, it is difficult to clinically test the X-ray of the radiological apparatus in a human body.

In addition, it is difficult to accurately predict how X-ray affects lesion cells and normal cells because there is movement of each organs through respiration when radiation is irradiated on lesion cells, and size and shape are different for each organ. .

In the case of a conventional art equipped with a simulated phantom,

Korean Patent Registration No. 10-0825894 entitled " Phantom Apparatus Having Long Term Simulated Phantom "can realize any desired pattern movement, so that even if the radiation target site in the patient's body is located in an organ moving according to the respiration, A phantom device having a long-term simulation phantom capable of accurately grasping the distribution and enhancing the therapeutic effect through precise management of the radiotherapy equipment is provided.

In addition, Japanese Patent Registration No. 10-1528436 entitled " Four-dimensional breathing simulation phantom device for simulating patient movement "reproduces the motion of the internal organs model and the abdominal model in the same manner as the actual patient environment, The present invention provides a four-dimensional respiration simulation phantom device that simulates a patient's movement independently controlling abdominal and thoracic motion even when there is no correlation between movement and chest movement.

In addition, when we look at the currently developed products, the movement of the product is realized by simple horizontal and vertical movements, whereas the breathing of the human body is not simple horizontal and vertical directions, and there is irregular movement in each organ. Therefore, the similarity with the human body falls.

Accordingly, the present invention has been proposed in order to solve such a problem. By implementing a model of a lesion cell similar to a cell to be actually treated with a lung, it is tested whether the radiation treatment apparatus accurately exposes the radiation to a lesion cell model, And to provide a motion phantom that inspects the safety of the robot.

According to an aspect of the present invention, there is provided a hinge type lattice acrylic box capable of observing the inside from outside; A 3D printing contour having a shape of a part of a body organ installed inside the hinged lattice acrylic box; A driving unit installed inside the 3D printing contour to cause motion to occur; A circuit board connected to and controlling the driving unit; A contour which is a surface covering the 3D printing contour; A motor driver for driving the motion expression of the body organ and the motion representation of the lesion cell displacement in the 3D printing contour; And a lesion cell model adhering to the outer surface of the contour. The X-ray image and the displacement of the lesion table can be measured by expressing the body organs of the individual by the rotation cycle of the motor and the RPM setting.

In such a motion phantom, the motor driving unit may enable remote driving and motion control to the terminal through the Bluetooth chip.

According to this motion phantom, when the safety inspection of the radiation equipment is carried out, the risk of the human body test can be eliminated and more accurate equipment testing is possible. In addition, because the real size of the pen model is similar to that of the real world, it is possible to express the motion function similar to that of the real world, and it is possible to control the displacement of the lesion cell by programming so that the behavior can be expressed considering the respiratory cycle and the degree of change of the lung skin. . It is possible to remotely control motor RPM and rotation cycle by applying Bluetooth function, and it is possible to operate and control it with smart phone, so it is convenient to use the product. In addition, it is possible to operate as a terminal like a smart phone by using the Bluetooth function as a unique designation. When attaching and measuring a marble ball, which is a model of a lesion cell, displacement can be visually observed through a hinged grid acrylic. In addition, accurate displacement can be measured during X-ray imaging, and it is possible to check the accuracy of treatment for actual lesion cells. Since the rechargeable battery is used for the power supply, the power supply cable is not needed separately, thus enhancing the ease of use.
