DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a patient or a subject who can accurately irradiate a target organ with radiation or the like when performing radiotherapy or radiological diagnosis from outside the human body, and which is generated with respiration. A synchronization point determining method capable of accurately synchronizing the respiratory phase without reducing the influence of the body movement of the patient (hereinafter referred to as "patient") and without making an individual difference in the judgment; and a respiratory phase monitor used for the same. Related to the device.

2. Description of the Related Art Conventionally, radiological medical devices using radiation such as X-rays, gamma rays, neutrons, protons, and particle beams have been developed and widely used. In particular, X-ray is a medical device that is indispensable for diagnosing details of the affected area, such as gastric cancer, pulmonary tuberculosis,
It is widely used on a daily basis for diagnosis and examination of fractures. In addition, neutron beams, proton beams, particle beams, and the like have recently shown great power in cancer treatment and the like.

In the treatment using radiotherapy equipment, it is extremely important that the affected part be irradiated with radiation accurately. Therefore, it is necessary to concentrate the radiation on the affected part and to minimize the irradiation on the normal part. desirable. To do this,
The movements of the organs of the patient etc. must be properly managed. Similarly, in a diagnostic apparatus such as an X-ray diagnostic apparatus and a computer tomography apparatus (CT), it is important to appropriately control the movement of an organ such as a patient in order to obtain a clear image.

As described above, when using a radiotherapy device or a radiological diagnostic device, it is important to control the movement of an organ of a patient or the like, but it is very difficult to execute the process, and the problem is solved only by the radiotherapy device. It is not simple. That is, the position of the affected part to be treated or diagnosed periodically and largely fluctuates due to the movement of the body such as the chest and abdomen which occurs with the breathing of the patient and the like.
The magnitude of this variation can be as much as 3-4 cm depending on the location.

[0005] It is extremely difficult to predict such movements associated with breathing, including sudden movements. The conventional practice is to temporarily stop breathing when irradiating radiation and stop breathing. Irradiation was performed with little movement of the body. That is, in a phase when a patient or the like breathes periodically (hereinafter referred to as a respiratory phase), the breathing operation is temporarily stopped (this is a normal method) while exhaling air from the lungs, and A method of performing treatment and diagnosis by irradiating radiation with this paused respiratory phase is fixed.

However, in such a method of synchronizing the respiratory phase with the radiation therapy equipment, not only the result varies depending on the individual's sensory judgment, but also the physical (physical) object to be treated or diagnosed. There was a great difference between individuals, and it was very difficult to irradiate accurately, requiring skill.

[0007] Such problems are basically the same not only in radiation therapy equipment and radiation diagnostic equipment, but also in MRI diagnostic equipment, ultrasonic diagnostic equipment, and the like. Depending on individual differences, accurate treatment and diagnosis required skill.

Therefore, in order to eliminate such individual differences,
Conventionally, a respiratory synchronization control medical device has been proposed (JP-A-200
0-201922). This conventional respiratory-synchronous control medical device is characterized by utilizing the function of a semiconductor position detecting element (PSD), and the position of a light source or the direction of a light beam fluctuates in response to the fluctuation of the epidermis of a living body in conjunction with respiration. An infrared light emitting diode, a PSD that receives light from the infrared light emitting diode as a fluctuation signal of the epidermis of a living body, and converts it into an electric signal corresponding to the respiratory cycle phase, and other controlled equipment based on the electric signal A respiratory synchronization controller is constituted by a control circuit that sends an operation control signal of
It detects the respiratory phase of a living body simply, accurately, and quickly, converts this detection signal into a control signal of a device, and sends it out.

This conventional respiratory synchronization control medical device controls a medical device by generating a synchronization signal at a timing before a patient or the like shifts to a respiratory operation from a phase signal waveform obtained by detecting light from an infrared light emitting diode by a PSD. The control of the radiation therapy equipment, the radiation diagnostic equipment, the MRI diagnostic equipment, the ultrasonic diagnostic equipment and the like can be stabilized.

[0010]

As described above,
With the breathing operation temporarily stopped in the state of exhaling air, radiation and the like are radiated at the paused respiratory phase, and the synchronization point determination method in the conventional respiratory phase, which performs treatment and diagnosis, makes judgments with individual senses In addition to being mixed, the physical differences between individuals were large and it was extremely difficult to irradiate accurately.

A conventional respiratory synchronization control medical device proposed in Japanese Patent Application Laid-Open No. 2000-201922 uses a phase signal waveform obtained by detecting light from an infrared light emitting diode with a PSD before a patient or the like moves to a respiratory operation. Since a medical device is controlled by generating a synchronization signal at a timing, the control of a treatment device, a diagnostic device, and the like (hereinafter, referred to as a medical device) can be stabilized. Since it is used by sticking on the body surface, the light source unit becomes relatively large, the optical axis is blurred, it is difficult to handle, and it is difficult to accurately set the light irradiation direction to the PSD direction. . In addition, since it is an infrared light emitting diode, the PSD has to be arranged at a relatively short distance due to the need to increase the sensitivity, and this has been a hindrance to medical practice by medical equipment. Furthermore, control of the medical device after detecting the synchronization signal can be expected to be relatively accurate control. However, the configuration of the light source section for obtaining the synchronization signal, which is the premise of this control, greatly affects the effect of the physical condition. When a sudden occurrence of a breathing motion occurs, the accuracy immediately deteriorates.

Furthermore, in this respiratory synchronization control medical device, no information on the timing of medical treatment is provided to a patient or a person to be diagnosed, and the patient or the person to be diagnosed is merely an object of treatment or diagnosis. . If, as in the conventional practice of determining the synchronization point in the primitive respiratory phase,
If cooperation could be obtained to synchronize the respiratory phase of the patient and the subject, the accuracy would have improved a little, but this was wasteful in ignoring it.

Further, even if a medical staff member such as a doctor intends to perform a medical act such as irradiation of radiation at the timing when he / she wants to perform treatment or diagnosis by examining the situation of a patient or the like, the setting of the timing is flexible. Could not be done. If a threshold is determined in a respiratory phase and only synchronization is mechanically performed at the same timing as in a conventional respiratory synchronization control medical device, a uniform medical action may be imposed. For example, in patients with intense movements, such as patients with asthma or cerebral palsy, synchronization is not always performed at the same timing as a healthy person, but at the timing that is most suitable for medical practice by examining individual situations. Synchronization is desirable.

[0014] In order for a patient or the like to make an effort to synchronize the respiratory phase with respect to a medical practice, there is a mental aspect in a light sense to confront the illness with a doctor or the like. Unlike the pause of
If this can be done accurately without individual differences, it is more desirable to have the patient or the like synchronize the respiratory phase.

Therefore, the present invention can accurately synchronize the respiratory phase without causing individual differences, does not affect the medical action by the medical equipment, is safe, and can be used for patients and diagnosed persons. It is an object of the present invention to provide a method for determining a synchronization point in a respiratory phase, which can provide information and can provide an effect on a mental aspect.

Further, the present invention can accurately synchronize the respiratory phase without causing individual differences, does not affect the medical practice by the medical equipment, is safe, and can be used by patients and diagnosed persons. It is an object of the present invention to provide an inexpensive respiratory phase monitoring device that can provide information and improve the effect in mental aspects.

[0017]

In order to solve the above-mentioned problems, a method of determining a synchronization point in a respiratory phase according to the present invention is to mount an outgoing light portion on a body surface and to transmit light generated by a light source portion from the outgoing light portion. While irradiating the light receiving unit, one point is set as a synchronization point from the trajectory of the light point moving on the light receiving unit, and the synchronization point is displayed as the fixed point along with the movement of the light point. In this case, when the patient or the like temporarily stops breathing, the medical device is operated at the same time.

This makes it possible to accurately synchronize the respiratory phase without causing individual differences, and to provide information to patients and diagnosed persons safely without affecting medical treatment by medical equipment. Can be effective in terms of mental health.

Further, in the respiratory phase monitoring apparatus according to the present invention, the light emitting unit is mounted on the body surface, and the light source unit converts the change information of the body surface into a change in the direction of the irradiated light and outputs the light. A light-transmitting or semi-transmitting light-receiving plate is displayed, on which light emitted from the light-emitting device is illuminated and fluctuation information is displayed as movement information of light spots formed on the front and back surfaces, and the back surface of the light-receiving plate A synchronization point setting unit for setting a point in a locus drawn by the light point as a synchronization point, and setting the synchronization point in the synchronization point setting unit; Are simultaneously displayed on the light receiving plate, and when the synchronization point and the light spot overlap, the medical device is operated at the same time as the patient stops breathing.

[0020] Thereby, the respiratory phase can be accurately synchronized without any individual difference, and the information can be safely and safely provided to the patient and the patient without affecting the medical action by the medical equipment. Thus, an inexpensive respiratory phase monitor that can provide an effect on the mental side can be provided.

Note that a material such as glass may be used instead of the plastic material. Thereby, even if the laser beam 6 is irradiated on the light receiving plate 2, the light reflected to the eyes is reliably prevented by the absorber 2c.

Paste on the surface. Then, by confirming the emission direction by the aiming means 3f and adjusting the universal joint part 3,
Complete setting of the respiratory phase monitor. Next, the light source unit 1 is operated by the control unit 11.

The semiconductor laser element 1a is oscillated, and the micro lens 1c, the optical fiber connector 1d, the optical fiber 4
The laser beam 6 is guided through the light source and is irradiated toward the light receiving plate 2. Then, the light spot 7a is displayed on the irradiation surface 2a and the back face 2b of the light receiving plate 2, and the light spot 7a starts moving on the trajectory 7 with the breathing motion of the patient or the like.

The doctor or the like determines the position of the synchronization point for synchronizing with the medical action of the medical device by comprehensively judging while watching the locus 7. Then, the synchronization point indicator 5 is arranged and adhered to the position of the synchronization point on the back surface 2b of the light receiving plate 2. As a result, the synchronization point is set on the trajectory 7 as a fixed point. The synchronization point is displayed together with the moving light spot 7a.

The patient or the like moves the locus 7 of the light spot 7a on the bed.
And the fluorescence of the synchronization point indicator 5 can be simultaneously watched, so that the inspiration of the breathing motion is repeated so that the trajectory 7 drawn by one's own breathing crosses the synchronization point. When the breathing motion becomes stable, the breathing phase appears as a stable orbit.

At this point, the physician or the like judges that he is ready to perform a medical procedure, selects the timing of the medical procedure, and instructs the patient or the like to pause breathing when the synchronization point and the light spot 7a overlap. The patient or the like temporarily stops breathing when the synchronization point and the light spot 7a overlap. At this timing, the doctor or the like presses the medical device operation switch 10 to irradiate radiation, ultrasonic waves, or the like.

As described above, since the light spot 7a moving in real time is displayed at the same time as the synchronization point and synchronized by the patient, there is no individual difference depending on intuition as in the prior art, and the respiration phase can be accurately determined. Can be synchronized. Light spot 7
Since the synchronization point is set by selecting one point from the locus 7 of a, it is very easy for the patient to synchronize. Since the laser beam 6 generated by the light source unit 1 is received by the light receiving plate 2 for synchronization, the presence of the respiratory phase monitoring device does not affect the medical treatment by the treatment device or the diagnostic device. The respiratory phase monitoring device according to the first embodiment is inexpensive, safe, and provides a patient and a patient with information for synchronizing and information for timing of performing a medical procedure, and can provide an effect on a mental aspect. .

Light is received on the surface 2a. This configuration is different from that of the first embodiment only.
