Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a medical X-ray imaging apparatus used in a hospital or the like.

[0002]

2. Description of the Related Art Fluoroscopic imaging has been widely used for medical examination and diagnosis. In general medical X-ray fluoroscopy, depending on the purpose, either the radiography in the standing posture in which the subject is upright or the supine posture in the state where the subject is lying on the bed, or Both are often done. The conventional general procedure when an outpatient goes to a medical institution to undergo a diagnosis including X-ray photography is as follows.

First, the subject is an internal medicine, surgery, orthopedics, etc.
When the doctor in charge receives a diagnosis and the doctor determines that X-ray imaging is necessary, a prescription describing imaging conditions (imaging posture, imaging site, etc.) is created. The subject goes to the radiology department at the instruction of the doctor, while the prescription is carried to the radiology department by the hand of a nurse or the like. In the X-ray room of the radiology department, a device for standing and a device for lying down are installed.
The technician in charge instructs the subject to be in a standing or lying position according to the contents described in the prescription, and manually sets conditions such as an imaged site in any of the devices.
Then, X-ray fluoroscopy is performed to print the captured image on the film. The photographed image thus obtained is delivered to the examination room where the doctor is present by the hand of a nurse or the like. The doctor examines the photographed image in the examination room.

[0004]

The conventional X-ray imaging method as described above has the following various problems. (1) Medical institutions must deploy both X-ray imaging devices for standing and lying down, which imposes a heavy cost burden. (2) The setting of imaging conditions such as alignment when performing X-ray imaging must be done manually by the engineer in charge, which is troublesome and work efficiency is poor. Also, if the technologist's skill or experience is insufficient, there is a possibility that imaging mistakes will occur, and time and cost will be wasted when re-imaging, etc., and the exposure dose to the subject will increase. Occurs. (3) It is troublesome to exchange the prescription written by the doctor and the photographed film between the radiology department and the doctor in charge of the examination. In particular, if the name of the subject is not clearly written on the film, it may be confused with that of another subject or may be lost during transportation.

Needless to say, in the medical field, human error is particularly relevant to the life of the patient. Therefore, various procedures and agreements are established to prevent such mistakes. However, even in medical devices and medical systems, it is required to cover such human errors and differences in individual skills, and by combining them, the reliability of medical care can be further enhanced. One of the objects of the present invention is to provide a medical X-ray imaging apparatus capable of compensating for human error and lack of skill and ensuring high reliability. Another object of the present invention is to provide a medical X-ray imaging apparatus capable of reducing the cost required for equipment in a medical institution.

[0006]

Means for Solving the Problems and Effects The medical X-ray imaging apparatus according to the present invention made to solve the above problems is a) a top plate on which a subject lies down, and b) the subject. X-ray irradiating means for irradiating the examiner with X-rays, and c) X-ray detecting means in which minute X-ray detecting elements are two-dimensionally arranged in order to detect the X-rays passing through the subject. And d) holding the X-ray detection means rotatably between a horizontal posture and a vertical posture, and also lying down the imaging position and the top plate in which the X-ray detection device is inserted below the top plate. A first holding means that is movable between a predetermined standing imaging position that does not interfere with e), and e) the direction of emission of X-rays from the X-ray irradiation means can be changed between downward and lateral directions. The X-ray irradiating means is held by the X-ray irradiating means, and the X-ray irradiating means and the X-ray detecting means are erected above the tabletop. A second holding means that is movable between an upright imaging position that faces the X-ray detection means while sandwiching the subject when in the imaging position; It is characterized in that the X-ray fluoroscopic imaging is selectively performed in the lying position on the floor and the standing position standing at a predetermined position on the floor.

That is, when performing X-ray fluoroscopic imaging on a subject lying on the top, the X-ray irradiating means is the second.
The holding means is arranged above the top plate, that is, above the subject, and the X-ray irradiation direction is downward. On the other hand, the X-ray detection means is maintained in a horizontal posture by the first holding means and is inserted below the top plate. As a result, the X-ray irradiating unit is arranged above and the X-ray detecting unit is arranged below the subject with the subject in the recumbent posture on the tabletop. Further, when performing X-ray fluoroscopic imaging on a subject in a standing posture, the X-ray detecting means is maintained in a vertical posture by the first holding means, and a predetermined standing photographing position that does not interfere with the top plate. Is moved up to. For example, when a chest image is taken, the examinee stands up with his / her chest pressed against the detection surface of the X-ray detection means. On the other hand, X
The X-ray irradiating means holds the subject by the second holding means and holds X.
The X-ray irradiation direction is set to a sideways direction so that the X-ray irradiation direction is directed to the subject. As a result, the X-ray irradiating means and the X-ray detecting means are arranged so as to face each other substantially laterally across the subject in the standing posture.

As described above, according to the medical X-ray radiographing apparatus of the present invention, the X-ray irradiating means and the X-ray detecting means, which are the main parts of the apparatus, are shared between the standing radiography and the recumbent radiography. The device becomes cheaper. Therefore, the cost when the medical institution introduces the device can be significantly reduced, and the cost for maintenance such as maintenance can be reduced.

Furthermore, the medical X-ray imaging apparatus according to the present invention has, in addition to the above-mentioned configuration, an imaging information acquisition means for externally acquiring imaging information on a subject, and the X-ray based on the acquired imaging information. It is preferable that the irradiation means and the X-ray detection means are provided with a control means for controlling the first and second holding means so that they are located at predetermined positions. Here, the photographing information fetching means can be configured to fetch photographing information from the outside via a communication network such as a LAN.

According to this structure, the X-ray irradiating means and the X-ray detecting means are automatically set in a state in which either standing or lying down imaging can be performed based on imaging conditions instructed by a doctor or the like. . Therefore, the troublesome operation and work by the person in charge of photography are reduced, and the work efficiency is also improved. Further, if the shooting position and other conditions regarding shooting are automatically set, inappropriate shooting due to human error by the person in charge of shooting is also eliminated. Further, since the photographing information is sent via the communication network, the trouble of carrying the prescription by hand becomes unnecessary, and mistakes such as loss can be eliminated.

Furthermore, as described above, when the medical X-ray imaging apparatus according to the present invention is connected to a communication network such as a LAN, data composing an imaged X-ray fluoroscopic image is transferred to the communication network. It is more preferable that the data format conversion means for converting the data into a transmittable format is provided above.

According to this structure, the computer directly at the doctor's hand via the communication network without burning the X-ray fluoroscopic image photographed by the medical X-ray photographing apparatus on the film or storing it in the removable storage medium. To be displayed on the monitor screen, or registered / stored in a database built in the host computer. Therefore,
It saves you the trouble of carrying a film or removable storage medium by hand, prevents it from being lost or confused with another person's, and allows the doctor to see the shot image immediately after shooting, which improves the efficiency of diagnosis and treatment. .

Further, in the configuration for controlling the operations of the first and second holding means by fetching the photographing information from the outside via the communication network, it is necessary to take the photographing information from the outside via the communication network. An informing means for informing, an operation start accepting means for accepting an operation start instruction from an operator, and an X-ray irradiating means and an X-ray detecting means are used until the operation start instruction is accepted after informing by the informing means. It is preferable that the control means further comprises a standby means for waiting at the position, and the control means starts the control of the first and second holding means in response to an operation start instruction from the operation start reception means.

According to this structure, the operator does not start the operation immediately after the photographing information fetching means fetches the photographing information but the operator informs that the first and second holding means fetch the photographing information by the notifying means. Then, the first and second holding means hold the X-ray irradiating means and the X-ray detecting means in their original positions by the waiting means, and the first and second holding operations are performed only when the operator gives an instruction to start the operation. 2 The operation of the holding means is started. Therefore, the operator can move the X-ray irradiating means and the X-ray detecting means so that the X-ray irradiating means and the X-ray detecting means are located at predetermined positions after sufficiently confirming safety such as no obstacles around the operator. As the notification means, visual attention such as display,
Audible attention such as a warning sound may be given.

Similarly, as a preferable structure for ensuring safety, obstacle detecting means for detecting an obstacle when the first holding means and / or the second holding means are moved, and an obstacle detecting means for detecting the obstacle are provided. It may be configured to further include movement stopping means for stopping the movement of the first holding means and / or the second holding means.

According to this configuration, when an obstacle such as a person (subject or the like) or an object is present on the movement path after the first and second holding means start moving, or when the obstacle is close to the obstacle. In addition, the movement is automatically stopped to avoid a collision. Therefore, even if the movement of the first and second holding means is started in an unsafe state due to an operator's oversight or an operation error, or an unsafe state in which a person unexpectedly approaches the device. Even in the case of occurrence of, it is possible to avoid the first and second holding means from colliding with the obstacle.

In general, in the recumbent shooting, the shooting is performed with reference to the center, in which the shooting areas are set symmetrically with respect to the center of the shooting surface, while in the standing shooting, the center of the upper edge of the shooting surface is set. This is an upper standard shooting in which the shooting area is set symmetrically with respect to the vertical axis. Therefore, also in the medical X-ray imaging apparatus according to the present invention, the read-out region of the X-ray detection element in the X-ray detection means is changed according to the horizontal or vertical posture of the X-ray detection means to perform X-ray fluoroscopy. It is preferable that the configuration is performed. According to this configuration, it is possible to reliably photograph a desired part in each photographing.

DETAILED DESCRIPTION OF THE INVENTION A medical X-ray imaging apparatus according to an embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is an overall configuration diagram of a medical X-ray imaging apparatus according to the present embodiment, FIG. 2 is a front view of a main part at the time of lying down imaging, and FIG. 3 is a front view of a main part at the time of standing imaging.

In FIG. 1, a range surrounded by a dotted line indicated by A shows the position of each part at the time of lying down photographing, and a range surrounded by a dotted line shown by B shows the position of each part at the time of standing standing photographing. .
That is, on the floor surface F of the imaging room R, a mounting table 10 having a U-shaped vertical cross section for mounting the subject P is provided at the upper part, and is elevated in the direction of arrow M1 in FIGS. A free lifting platform 11 is installed. Next to the rail, a holding table 13 for holding the FPD unit 12 having a two-dimensional X-ray sensor (hereinafter referred to as "FPD" because it is a flat panel X-ray sensor) 12a is laid on the floor surface F. It is provided movably along the direction of arrow M2 in FIG.

The FPD unit 12 is attached to an arm 13a protruding laterally from the holding table 13, and the height of the FPD 12a is changed by moving the arm 13a up and down in the direction of arrow M3 in FIGS. The FPD 12a is freely movable, and the FPD 12a is switched to the horizontal state or the vertical state by rotating the arm 13a in the direction of the arrow M4 in FIGS. The FPD unit 12 has a built-in obstacle sensor 12b for detecting the presence of an obstacle in the moving direction. As the obstacle sensor 12b, a conventionally known one such as an infrared sensor can be used. Further, an indicator lamp 13b is provided above the holding table 13.

The FPD 12a has a structure in which a predetermined number of minute X-ray detecting elements are arranged in the vertical and horizontal directions in a plane, and each X-ray detecting element is connected to a read wiring running in the vertical and horizontal directions via a TFT. In addition, the read wirings are connected to the horizontal read drive section or the vertical read drive section, respectively, and the read drive signal is supplied to the horizontal and vertical read drive sections. Addresses corresponding to the rows and columns are assigned to each X-ray detection element, and it is possible to read the signal of a specific X-ray detection element by designating the address. Here, for example, the number of pixels (the number of elements)
2700 × 2700 FPD is used. In addition, FPD
The specific configuration of the above can be the one already described in Japanese Patent Application No. 9-324430 (JP-A No. 11-155851) by the present applicant.

A rail 16 for moving the X-ray tube 15 is provided on the ceiling C of the radiographing room R, and the X-ray tube 15 is a suspending arm which can extend and contract in the direction of arrow M7 in FIGS. It is suspended and supported by 15a, and is reciprocally provided along the rail 16 in the direction of arrow M5 in FIG.
Furthermore, the X-ray tube 15 is rotatable about the axis with respect to the suspension arm 15a in the direction of an arrow M6 in FIGS. 2 and 3, whereby the X-ray can be directed either directly below or directly beside. It is possible to switch and irradiate. It is also possible to actually stop the rotation during the rotation and irradiate the X-ray with a certain angle.

In this medical X-ray photographing apparatus, the X-ray tube 15 which is an X-ray irradiating means is used during the recumbent photographing and the standing photographing.
And the FPD 12a which is the X-ray detecting means are commonly used. That is, at the time of lying down imaging, as shown in the range A in FIG. 1 and as shown in FIG. 2, the FPD 12a is in a horizontal state and is inserted below the top plate of the mounting table 10, whereby the X-ray tube positioned on the ceiling C is positioned. The subject P is placed between the two. On the other hand, at the time of standing imaging, as shown in the range B in FIG. 1 and in FIG. 3, the FPD 12a moves vertically and moves to a position away from the lifting table 11, and the X-ray tube 1
5 also moves to a position where the subject P is sandwiched between the FPD 12a and the suspension arm 15a, and the X-ray tube 15 moves 90 degrees.
Rotate to face the subject P's back. In this medical X-ray imaging apparatus, since the X-ray tube 15 and the FPD 12a, which account for a large proportion of the cost in the entire apparatus, are shared in this way, the apparatus for recumbent imaging and standing imaging is separately provided. It is possible to significantly reduce the cost as compared with the case of preparing.

The processing / control unit 2 is at the center of the control of each of the above units.
0 is set, and the movement control unit 23 that receives a control signal from the processing / control unit 20 integrally controls the positions (that is, movement and rotation) of the above respective units. The irradiation control unit 24 also controls the X-ray irradiation from the X-ray tube 15. On the other hand, FPD1
The output of each X-ray detection element 2a is converted into a digital value by the A / D conversion unit 22 via the data collection unit 21 and input to the processing / control unit 20. The detection signal of the obstacle sensor 12b is determined by the obstacle detection unit 35, and the result is input to the processing / control unit 20.

The processing / control unit 20 can be configured as a device dedicated to this X-ray imaging apparatus, but the same function can be realized by installing and executing predetermined software in a normal computer. . The processing / control unit 20 includes a large-capacity storage device 25 for storing captured X-ray fluoroscopic image data, a film recording unit 26 for printing the captured X-ray fluoroscopic image on a film, an X-ray fluoroscopic image, A monitor 27 for displaying other information, an input unit 28 including a pointing device such as a keyboard and a mouse, and the like are connected.

Further, the processing / control unit 20 is connected to the in-hospital network 32 via a communication control unit 29 having a communication function such as a modem. The in-hospital network 32 is, for example, a closed communication line network such as a LAN laid in a medical institution in which the X-ray imaging apparatus is installed, and an individual computer 34 installed in each medical doctor or department and a medical history of a patient. A host computer 33, etc., which holds various information including the above as a database, is also connected. Further, the processing / control unit 20 is also connected to a card reader 30 capable of reading a card 31 handed to each subject. Card 3
Reference numeral 1 denotes, for example, a magnetic card or an IC card, which holds at least identification information (such as an ID code) of the subject who holds the card.

If the card has a large storage capacity such as an IC card, it is possible to write the photographing information on this card at the time of receiving a diagnosis from a doctor. In that case, the imaging information is passed to this X-ray imaging apparatus without passing through the in-hospital network 32. However, from the viewpoint of preventing leakage of personal information from the card, it is preferable to store only the minimum necessary information such as identification information in the card and send the photographing information via the in-hospital network.

The data collecting unit 21 is configured to read out the signal of the X-ray detecting element at the address determined in a predetermined order. However, the FPD 12a is used during the recumbent imaging and the standing imaging. The read-out area of all the areas is different. This point will be described with reference to FIG. 4A and 4B are diagrams showing a read-out area on the FPD 12a, where FIG. 4A is a state during standing imaging and FIG. 4B is a state during lying down imaging.

When standing upright, the subject is the FPD unit 1
2 Place the chin on the upper edge and take a picture. Therefore, FPD
The reading area is set symmetrically with respect to the vertical line at the center of the upper end of 12a. On the other hand, at the time of lying down imaging, the center of the FPD 12a is used as a reference and the reading areas are set symmetrically in the vertical and horizontal directions. By changing the read-out area in this way, it is possible to reliably capture the part to be photographed.

Next, an example of the operation of the medical X-ray imaging apparatus will be described according to the imaging procedure. First, the examinee P goes to a desired medical examination department such as internal medicine or surgery to undergo medical examination. When the doctor determines that the X-ray fluoroscopic imaging is necessary, the doctor inputs the imaging information described below from the computer 34 at hand. Of course, such work is not always performed by the doctor himself, and may be input by another person according to the prescription written by the doctor. The imaging information input in this way is the subject P.
It is sent to the in-hospital network 32 in association with the identification information of and stored in the storage device of the host computer 33. The subject P who has received an instruction from the doctor goes to the radiology department with the card 31 in which the identification information of the subject is stored.

The person in charge of the radiation department receives a card 3 from the examinee P.
1 is received and mounted on the card reader 30, and the input unit 28
Perform a predetermined operation from. Then, the card reader 30 reads the identification information from the card 31, and the processing / control unit 2
Give to 0. The processing / control unit 20 inquires the identification number from the communication control unit 29 to the host computer 33 or another computer 34 via the in-hospital network 32 in order to acquire the imaging information of the subject P to which the identification information is added. Then, the latest shooting information, that is, the shooting information about the shooting to be performed, is received. The shooting information is at least selection information for standing or lying down (may be both).
Is included. Other than that, detailed imaging conditions such as an imaging site (for example, head, chest, abdomen, etc.) and an imaging angle may be included.

When the processing / control section 20 receives the photographing information from the communication control section 29, it first turns on the indicator lamp 13b.
That is, the indicator / light 13b is turned on when the processing / control unit 2
0 has already received the imaging information and indicates that the FPD 12a and the X-ray tube 15 are ready to be moved to a predetermined imaging position. Since the person in charge can immediately see whether the indicator light 13b is turned on or off,
The person in charge recognizes that the device is in a standby state by turning on the indicator light 13b and confirms the safety around the device. That is,
When the FPD 12a and the X-ray tube 15 move, it is confirmed whether or not the subject P is present at a position in contact with the FPD 12a and the X-ray tube 15, or whether another obstacle is left on the movement route. If the safety is confirmed, a predetermined operation is performed by the input 28 to instruct the start of the operation. In response to this instruction,
The processing / control unit 20 sends a control signal based on the shooting information to the movement control unit 23. As a result, the movement control unit 23 first moves the X-ray tube 15 and the FPD unit 12 to either the recumbent imaging (range A in FIG. 1) or the standing imaging (range B in FIG. 1). Then, when the imaging region is set, it is moved to a position where imaging of the setting region is possible within the above range. However, since the same imaged part is not always obtained at a certain position depending on the physical constitution of the subject P, automatic setting of the imaged part is a rough adjustment, and the person in charge manually sets it as described later. It is desirable to make fine adjustments.

While the movement control section 23 is controlling the operation, the obstacle detection section 35 judges the detection signal from the obstacle sensor 12b and confirms whether or not there is an obstacle in the movement direction. Even if the person in charge confirms the safety of the surroundings first, if the subject P suddenly approaches the device, the safety may be impaired. Therefore, when the obstacle detection unit 35 determines that there is an obstacle, the processing / control unit 20 instructs the movement control unit 23 to temporarily stop the movement operation, for example, by sounding a warning buzzer (not shown). Call attention to the person in charge and the subject. In this way, when the movement operation is temporarily stopped, it waits in that state until the person in charge instructs the operation section 28 to restart the operation, so that a very high degree of safety can be secured. Of course, it is more preferable to provide a switch for urgently stopping the movement of the device as described above at an appropriate place such as the input unit 28.

The person in charge confirms the completion of the movement of the apparatus as described above, and instructs the subject P to hold the posture at a predetermined position. For example, if the doctor has instructed to take a chest image in a standing position, the X-ray tube and the FPD unit are indicated by B in FIG.
Range, that is, the X-ray tube 15 'and the FPD unit 12'
Is located in. Therefore, the subject P is instructed to stand upright with the chest closely attached to the FPD unit 12 '. In response to this, the subject takes the posture shown by P'in FIG. The person in charge performs fine adjustment of the imaged region as appropriate and then performs a predetermined operation from the input unit 28 to instruct the start of the image capturing operation. In response to this instruction, the irradiation control unit 24 drives the X-ray tube 15 and irradiates the subject P ′ with X-rays for a predetermined time.

The FPD 12 is operated during the irradiation of X-rays.
The signal output from a'is passed through the data collection unit 21 and is sent to A /
It is input to the D conversion unit 22, converted into a digital value for each detection signal by each X-ray detection element, and sent to the processing / control unit 20. Then, it is stored in the storage device 25 as data constituting one X-ray fluoroscopic image. At the same time, processing
Predetermined image signal processing is performed in the control unit 20, and the result is displayed on the screen of the monitor 27 as an X-ray fluoroscopic image. Therefore, the person in charge can confirm whether or not the image is surely taken by looking at this image. If there is no particular problem in photographing, the person in charge performs a predetermined operation using the input unit 28. As a result, the fluoroscopic image captured previously is determined as the captured image for the subject P.

The image data stored in the storage device 25 is
It is immediately sent to the host computer 33 via the in-hospital network 32 together with the identification information and the photographing information of the subject P and stored in the storage device of the host computer 33.
Therefore, after that, the doctor in charge is in charge of the computer 3 at hand.
It is possible to retrieve the identification information of the subject P from 4 and retrieve the X-ray fluoroscopic image previously captured and display it on the monitor screen. For example, when the image data is stored in the host computer 33, the image data is sent to the computer 34 at the same time as the doctor in charge, or the computer 34 is notified that the image data is stored in the host computer 33. If set to, the doctor in charge can see the X-ray fluoroscopic image on the monitor of the computer 34 immediately after photographing. As before,
In the X-ray imaging apparatus, it is also possible to print the X-ray fluoroscopic image on the film by the film recording unit 26 based on the image data stored in the storage device 25.

As described above, according to the X-ray imaging apparatus of the present embodiment, a series of operations from the first doctor's instruction for imaging to the viewing of the captured X-ray fluoroscopic image are extremely efficient and It can be implemented so that human error is unlikely to occur.

Naturally, the above embodiment is merely an example of the present invention, and it is obvious that appropriate changes and modifications can be made within the scope of the present invention.
