[Industrial applications]
According to the present invention, when an operator or the like performs a catheter operation or the like on a subject, a support mechanism that supports the X-ray tube and the image intensifier, a table on which the subject is placed, and the like are touched with their operation means. The present invention relates to an X-ray diagnostic apparatus such as an X-ray fluoroscopic apparatus and a circulatory organ X-ray inspection system which can be controlled without the need.
[0002]
[Prior art]
FIG. 5 shows a cardiovascular X-ray inspection system as a conventional X-ray diagnostic apparatus. In FIG. 5, reference numeral 1 denotes a subject, 2 denotes a table on which the subject 1 rests, 34 denotes a television monitor for observing an X-ray image, and 35 denotes an image intensifier (hereinafter referred to as II) 36. A support mechanism for supporting the X-ray tube 37 is provided. I. This is a support mechanism for supporting the forty. Reference numeral 3 denotes an operation device provided with a switch (not shown) for controlling the support mechanisms 35 and 38, the table 2, and the like.
[0003]
This apparatus is used mainly for the purpose of contrast examination of blood vessels such as the heart, head, and abdomen. For example, for a subject 1 having a heart disease, a catheter ( (Not shown) is inserted, and the inside of the blood vessel is advanced toward the heart while confirming the progress of the operation on the television monitor 34 by X-ray fluoroscopy. In particular, when the catheter is advanced toward the heart or head while selecting a blood vessel, it is difficult to understand the state of the complicated blood vessel traveling only by one-way fluoroscopy, making the catheter advancement difficult.
[0004]
Therefore, in this device, the blood vessel can be seen from another angle by changing the fluoroscopic direction, and the running of the blood vessel can be easily confirmed. Also, in order to widen the field of view of the part being photographed or enlarge the image, I.P. I. 36 can be raised and lowered. During inspection, such an I.D. I. 36 may be moved up and down.
[0005]
Further, not only the imaging system (II 36, X-ray tube 37) supported by the support mechanism 35 but also the imaging system (II 40 and X-ray tube 39) supported by the support mechanism 38. An X-ray fluoroscopic image can be obtained. Further, the support mechanism 38 has a structure capable of rotating in a direction parallel to the body axis of the subject 1, so that an X-ray fluoroscopic image at an angle that cannot be obtained by the imaging system of the support mechanism 35 can be obtained. Obtainable. On the other hand, the table 2 can move in the body axis direction A of the subject 1 and can change the height direction B.
[0006]
In this manner, the positioning of the imaging system is performed from multiple directions, and a target blood vessel is selected from a group of blood vessels that travel in a complicated manner, and an X-ray fluoroscopic image is obtained. The fluoroscopy is performed by operating the foot switch 14.
[0007]
In such an examination, when the above-described positioning is completed, a contrast agent is injected into the blood vessel through the catheter, and photographing, for example, film photographing by the cine camera 45 is performed.
[0008]
[Problems to be solved by the invention]
In the above-mentioned conventional apparatus, a treatment method using a catheter called interventional radiology (hereinafter referred to as IVR) has been actively performed in recent years. This is, for example, when there is an infarction in the annular artery, when treating this, insert a catheter from the aorta and the like, advance the catheter to the target blood vessel under X-ray fluoroscopy, at the target site, the balloon catheter And the use of an atherectomy catheter to open the stenosis.
[0009]
In such an IVR procedure, it is necessary to find a target blood vessel under X-ray fluoroscopy and quickly insert a catheter into the target blood vessel. , 38 and the table 2 must be moved. Such an operation, which was a conventional contrast test, became more necessary with an IVR procedure.
[0010]
However, in IVR, a target treatment site is determined from an X-ray image obtained at the time of diagnosis, and when actually performing treatment by IVR, the catheter is moved in a blood vessel and used as a guide to reach the target site. X-ray fluoroscopy becomes even more important. Then, a catheter is brought close to the region of interest, and a desired operation is brought to the center of the field of view of the cine camera 45, or a small operation is performed by slightly shifting the position.
[0011]
However, due to the IVR procedure, the operator's hand must be kept clean. Therefore, the operator touches the operating means of the apparatus with his / her own hand and operates the switch, for example, the operating device 3 as shown in FIG. Of the switch levers 41 to 46 and the switch buttons 47 to 50 cannot be commanded to control means (not shown).
[0012]
Therefore, a third party who does not directly touch the subject 1 performs a switch operation on behalf of the subject, or covers the switch levers 41 to 46 and the switch buttons 47 to 50 with a cover for hygiene maintenance, and always keeps a clean state. To keep the surgeon's hands clean.
[0013]
However, the former method, in which a third party performs the switch operation on behalf of the operator, has a problem that the procedure becomes complicated and the position state is not always as expected by the operator himself, and it takes time to perform positioning and the like. there were. In the latter method of attaching a cover for maintaining hygiene, there is a problem that a great deal of labor and time are required for the mounting and replacement work. In particular, in the IVR technique, an operation of frequently switching between a large number of switches is required, and the above problem becomes more remarkable.
[0014]
An object of the present invention is that a direct operator such as an operator can control each unit of the apparatus by himself without using his / her own hand, and can delegate a switch operation to a third party or sanitize a switch operation unit in advance. An object of the present invention is to provide an X-ray diagnostic apparatus which eliminates the need to cover a holding cover and can easily and quickly perform control of each section of the apparatus, particularly, control of positioning of each section of the apparatus in an IVR procedure.
[0015]

【Example】
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a configuration diagram showing an embodiment of an X-ray diagnostic apparatus according to the present invention. Here, a case where the present invention is applied to a circulatory organ X-ray inspection system similar to FIG. 5 is illustrated.
[0020]
1, the same reference numerals as those in FIG. 5 indicate the same or corresponding parts. Reference numeral 9 denotes a control device for controlling each part of the X-ray diagnostic apparatus. The control mechanism from the operation unit 3 activates a moving mechanism of each part of the X-ray diagnostic apparatus such as the table 2 and the support mechanisms 35 and 38, and controls an X-ray aperture. It controls opening and closing and controls the image display state of the television monitor 34, for example, the brightness and the like. Therefore, the control device 9 includes, for example, a moving mechanism operation controller 9a, an image display controller 9b, an X-ray aperture controller 9c, and the like.
[0021]
Reference numeral 5 denotes a voice input device for converting voice into an electric signal and outputting the voice signal. Reference numeral 6 denotes voice data based on an output signal of the voice input device 5 when receiving predetermined words for controlling a plurality of control means. This is a voice storage device that registers a plurality of speakers corresponding to speakers.
[0022]
Reference numeral 7 denotes a specific-speaker voice recognition / control command transmission device, which receives speaker-specific data set for each of a plurality of speakers, and is registered in the voice storage device 6 of the specific speaker. A standby state for comparison with audio data is entered. Then, when the voice input device 5 receives the word of the specific speaker, it determines which of the plurality of types of words for controlling the control means corresponds, and converts the word into a control command corresponding to the word. To the control device 9 to operate each part of the device in the same manner as when receiving a control command from the operation device 3.
[0023]
In this case, when the voice input device 5 receives the word of the specific speaker, the determination as to which of the plurality of types of control device control words corresponds is actually input to the voice input device 5 . This is performed by comparing the voice data of words with the voice data already registered in the voice storage device 6. In order to determine what control command the determined word means, a control command corresponding to each of the plurality of control device control words is determined in advance, and the control command is determined, for example, in a correspondence table (table). This is performed by having the specific speaker's voice recognition / control command transmission device 7 hold it.
[0024]
In the illustrated example, the specific speaker voice recognition / control command transmission device 7 includes a specific speaker voice recognition device 7a and a control command transmission device 7b. In this case, the control command transmission device 7b converts the discrimination result signal from the specific speaker voice recognition device 7a into a control command that can be received by the control device 9 and transmits the control command. It has the above functions. The specific speaker voice recognition device 7a is configured using, for example, a DSP (Digital Signal Processor) or the like.
[0025]
The reason why the voice data of a plurality of persons is registered in the voice storage device 6 and the number of recognition targets of the specific speaker is set to a plurality of persons is as follows. That is, usually, a person who performs diagnosis and treatment in a medical facility such as a hospital, in other words, the operator of the X-ray diagnostic apparatus is not limited to one person. This is to prevent the device from being operated by the words spoken by the person, and to allow only a plurality of limited persons (a plurality of specific speakers) to control and operate the device by their own voices. .
[0026]
Next, the operation of the device of the present invention will be described.
Now, a plurality of types determined in advance by a plurality of persons (a plurality of specific speakers: arbitrarily determined, but in this case, an IVR operator) who may perform diagnosis, treatment, and the like using the apparatus. It is assumed that the control device control word is registered in the voice storage device 6 as voice data via the voice input device 5 for the speaker. Further, on the operation device 3, a keyboard or a magnetic device for giving speaker identification data (ID data) set for each of a plurality of specific speakers to the specific speaker voice recognition / control command transmission device 7 is provided. It is assumed that an ID data input device (not shown) such as a card reader is provided.
[0027]
Hereinafter, the operation when the speaker A among the plurality of specific speakers uses the apparatus as an operator performing the IVR procedure will be described with reference to FIG.
(1) First, the fact that the person who will operate the device by voice from now on is the speaker A is input to the ID data input device on the operating device 3. As an input method, for example, when the ID data input device is a keyboard, the name or ID number of the speaker A is input from the keyboard. When the ID data input device is a magnetic card reader, A method of reading a magnetic card on which the name and ID number of the speaker A are recorded by the magnetic card reader is used.
[0028]
(2) When the speaker A is input to the specific speaker voice recognition device 7a, the voice data (registered voice data) of the speaker A already registered from the voice storage device 6 is recognized as the specific speaker voice recognition. The specific-speaker voice recognition device 7a is loaded into the device 7a, and enters a standby state for comparison between the loaded registered voice data of the speaker A and the voice data input from the current time via the voice input device 5.
[0029]
(3) In this standby state, the operator (speaker) A starts the IVR procedure on the subject 1. Now, it is assumed that the surgeon A utters the word (voice) “CRA 30 degrees”. Here, the CRA refers to an imaging system (II 40 and X-ray tube 39) in which an image to be projected is in the head direction, in other words, the position of the support mechanism 38.
[0030]
(4) The sound is input to the speech recognition apparatus 7a as voice data through the voice input device 5, already compared with the audio data within the registered voice data group of the operator A being loaded is performed.
[0031]
(5) Accordingly, the speech recognition device 7a recognizes the two words “CRA” and “30 degrees”.
(6) Then, the word "CRA" is determined and recognized as a command to move the support mechanism 38 to the CRA position of the movement mechanism operation controller 9a.
(7) Also, it is determined and recognized that the command target value is to move to the position of 30 degrees by the word "30 degrees".
[0032]
(8) The two determination results are transmitted as two control commands to the moving mechanism operation controller 9a of the control device 9 by the control command transmission device 7b.
[0033]
(9) The moving mechanism operation controller 9a selects a drive motor (not shown) of the support mechanism 38 for executing CRA.
[0034]
(10) Next, the drive motor is controlled so that the operation angle becomes 30 degrees, and the position control of CRA 30 degrees is completed.
[0035]
(11) If the surgeon A issues the word (voice) "monitor up", the voice recognition device 7a recognizes the three words "monitor", "luminance", and "up".
(12) Then, the word "monitor" is determined and recognized as a command to the image display controller 9b.
(13) Also, it is determined and recognized as a bright control command by “brightness”, and is determined and recognized as a command to set a predetermined brightness increase amount as a target value by “up”.
[0036]
(14) These three determination results are transmitted to the image display controller 9b as three control instructions by the control instruction transmission device 7b.
(15) The image display controller 9b receives these three control commands and increases the brightness of the television monitor 34 according to the command amounts.
[0037]
As described above, according to the device of the present invention, each part of the device is controlled only by the words of the surgeon A. From the viewpoint of the surgeon A, the surgeon A can arbitrarily operate the apparatus only by using words without using hands.
[0038]
In the above-described embodiment, the specific speaker voice recognition / control command transmission device 7 is constituted by the specific speaker voice recognition device 7a and the control command transmission device 7b, but the present invention is not limited to this. For example, as shown in FIG. 3, a quantification controller 7c may be added.
[0039]
Here, the quantification controller 7c quantifies the voice data based on the output signal of the voice input device 5 when receiving an ambiguous word, for example, a word such as "slightly" or "slightly", into a predetermined command content. It becomes something.
[0040]
Hereinafter, the device of the present invention having such a configuration will be described with reference to FIGS. 3 and 4 in which the same or corresponding parts as those in FIG. In this case, the above-mentioned ambiguous words such as "slightly" and "slightly" are words for controlling a plurality of kinds of control means, which are determined in advance by voice data for a plurality of persons, and are stored in a voice storage device corresponding to speakers. 6 is registered.
[0041]
(1) First, the fact that the person who will operate the device by voice from now on is the speaker A is input to the ID data input device on the operating device 3.
(2) When the speaker A is input to the specific speaker voice recognition device 7a, the voice data (registered voice data) of the speaker A already registered from the voice storage device 6 is recognized as the specific speaker voice recognition. The specific-speaker voice recognition device 7a is loaded into the device 7a, and enters a standby state for comparison between the loaded registered voice data of the speaker A and the voice data input from the current time via the voice input device 5.
[0042]
(3) In this standby state, the operator (speaker) A starts the IVR procedure on the subject 1. Now, it is assumed that the surgeon A has uttered the word (voice) “CRA 30 degrees”. (4) The sound is input to the speech recognition apparatus 7a as voice data through the voice input device 5, already compared with audio data that is in the registered voice data group of the operator A being loaded is performed.
[0043]
(5) As a result, the speech recognition device 7a recognizes the three words "CRA", "30 degrees", and "slightly".
(6) Then, the word "CRA" is determined and recognized as a command to move the support mechanism 38 to the CRA position of the movement mechanism operation controller 9a.
(7) Also, it is determined and recognized that the command target value is to move to a position of 30 degrees + slightly by the words “30 degrees” and “slightly”.
(8) Here, the quantification controller 7c receives the word "slightly" and converts it into a command target value of moving to a position of 30 degrees + α. The value + α can be arbitrarily set in the quantification controller 7c, but is set to １ ／ of the command angle here. Therefore, the command target value of moving to the position of 30 degrees + α is converted (determined and recognized) into the command target value of moving to the position of 36 degrees here.
[0044]
(9) The above three determination results are converted into three control commands (actually, two control commands of “CRA” and “36 degrees”) by the control command transmission device 7b, and the movement mechanism operation controller 9a of the control device 9 Is transmitted to.
(10) The moving mechanism operation controller 9a selects a drive motor (not shown) of the support mechanism 38 for executing CRA.
(11) Next, the drive motor is controlled so that the operation angle becomes 36 degrees, and the position control of CRA 36 degrees is completed.
[0045]
(12) If the surgeon A issues the word (voice) "monitor up", the voice recognition device 7a recognizes the three words "monitor", "luminance" and "up". The operation in this case is the same as in the above-described embodiment.
[0046]
As described above, according to the apparatus of the present invention illustrated in FIG. From the viewpoint of the surgeon A, the surgeon A can arbitrarily operate the apparatus only by using words without using hands. Further, when the surgeon A utters an ambiguous word such as “(CRA 30 degrees) little”, the word “slight” is ignored according to the apparatus of the present invention illustrated in FIG. It is determined and recognized as a specific numerical value by the quantification controller 7c. The word "slightly" is a commonly used word, and its quantification improves operability.
[0047]
【The invention's effect】
As described above, according to the present invention, a direct operator such as an operator can control each unit of the apparatus by himself without using his / her own hand, and can allow a third party to perform a switch operation, or There is no need to cover the switch operation section with a hygiene maintenance cover, and there is an effect that control of each section of the apparatus, particularly positioning control of each section of the apparatus in an IVR procedure, can be performed easily and quickly. Further, according to the present invention, even if a voice of an unspecified speaker, that is, a person who does not operate the device, enters the voice input device, the voice input device does not operate the voice input device.
[0048]
Furthermore, if the specific-speaker voice recognition / control command transmission device is configured by adding a quantification controller, even if an operator or the like utters an ambiguous word such as "slightly", specific numerical values can be obtained. Is determined and recognized, and control of each unit of the apparatus is performed, so that an effect that operability is further improved can be obtained.
