Description

  The present invention relates to an X-ray diagnostic treatment apparatus, and more particularly to an improvement of an X-ray diagnostic treatment apparatus using information from an interventional radiology simulator.

  In the X-ray therapy diagnostic apparatus, an image for transcutaneously treating a disease such as a blood vessel wall through a guide wire and a catheter is provided. And, for example, in Patent Document 1 below, an interventional radiology that treats a disease such as a blood vessel wall by advancing a guide wire or a catheter percutaneously inserted into a blood vessel along the running of the blood vessel. An X-ray therapy diagnostic apparatus is described that provides an image for performing interventional radiology (hereinafter referred to as IVR).

  Reaching the therapeutic device in a short time to the target site is important for reducing the burden on the patient undergoing treatment and reducing the risk of complications associated with the prolonged procedure. However, due to individual differences in blood vessel travel and the like, a technique based on the experience of the surgeon is required, and for an unskilled surgeon, there is a concern of increasing the aforementioned risk by repeating trial and error.

Therefore, an IVR simulator exists as a system for such surgeons (see, for example, Patent Document 2 below).
JP 2002-119507 A JP 2005-241883 A

  By the way, when operating intravascular devices for diagnosis and treatment such as guide wires and catheters along the blood vessels, there are individual differences and blood vessel malformations that are rarely seen. Special running conditions, such as malformed bifurcations, can interfere with the progression of the endovascular device in the blood vessel. In order to pass the blood vessel part in such a special running state, it is necessary to fully understand the possibility of individual differences and malformations, and if the knowledge is insufficient, it is necessary to pass the blood vessel part. There is also a risk that it will take time, put a burden on the blood vessels, and thus cause complications that also affect the general condition.

  Passing in a short time is important to reduce the burden on the patient being treated and to reduce the risk of complications associated with prolonged procedures. Necessary and unskilled operators have a concern of increasing the aforementioned risk by repeating trial and error.

  In addition, the IVR simulator described above is only a general treatment simulation, and since it is not in the stage of performing a treatment simulation for a patient to be treated in the future, a specific technique for a deformed running blood vessel peculiar to an individual is examined. It hasn't been done yet.

  Even if this IVR simulator is developed to pre-simulation (pre-examination) before actual treatment using an X-ray device based on the data of the patient to be actually treated, the information in the pre-examination is effectively used. This cannot be used for actual treatment by an X-ray apparatus.

  The present invention also provides an X-ray generation means for irradiating a subject with X-rays, and an X-ray detection for detecting the X-rays emitted from the ray generation means through the subject and converting them into an electrical signal. Means, a first storage means for temporarily storing the electrical signal converted by the X-ray detection means as image data, and an image for performing image processing on the image data stored in the first storage means In an X-ray diagnostic treatment apparatus comprising a processing means and a display means for displaying an image processed by the image processing means, it is detected during an examination using an intravascular device for diagnostic treatment.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

(First embodiment)
1 and 2 show an X-ray diagnostic treatment apparatus according to a first embodiment of the present invention. FIG. 1 is an external view showing the overall configuration, and FIG. 2 is a block configuration diagram showing the overall configuration.

  The X-ray diagnosis and treatment apparatus 10 of this embodiment includes a bed 11, an operation unit 12 provided on the bed 11, an X-ray generation unit 14, an X-ray detection unit 15, the X-ray generation unit 14 and the X-ray generation unit 14. The C-shaped C arm 16 in which the line detection unit 15 is disposed in an opposing relationship and a plurality of image monitors 17 are configured.

  The bed 11 is for placing the subject 20, and the X-ray generation unit 14 and the X-ray detection unit 15 are mounted on both ends of the C-arm 16 so as to face each other with the bed 11 interposed therebetween. The C arm 16 is driven to rotate by the C arm / bed mechanism control unit 27. At this time, the X-ray generator 14 and the X-ray detector 15 rotate around the same axis of rotation.

  The X-ray generator 14 includes an X-ray tube 31 and an X-ray restrictor 32. The X-ray tube 31 receives power supply from the high voltage generator 30 and emits X-rays toward an X-ray detector 33 (described later) in the X-ray detector 15. In the high voltage generator 30, the tube voltage and the filament current are arbitrarily adjusted by the system controller 25 via the X-ray control unit 29 and the C-arm / bed mechanism control unit 27. The system controller 25 controls the overall operation of the X-ray diagnostic treatment apparatus 10. The system controller 25 also controls the X-ray detector 33 in synchronization with the X-ray generation control by the X-ray tube 31.

  On the other hand, the X-ray detector 15 includes an X-ray detector 33 and a data converter (not shown). The X-ray detector 33 detects X-rays incident from the X-ray tube 31 through the subject 20 and outputs an electric signal corresponding to the intensity to the data converter. The image data converted by the data converter is sent from a detector interface (I / F) 41 in the system controller 25 via a bus 40 to a hard disk drive (HDD) 43 as a storage device and a memory 45 for primary storage. To be supplied.

  The system controller 25 includes a detector interface 41, an X-ray / support device control interface (I / F) 42, a hard disk drive 43, a main database (RAID) 44 storing past images for simulation, a memory 45, and a video. A (Video) circuit 47 and a simulator interface (I / F) 48 are included. The operation controller 12, the X-ray detector 15, the image monitor 17, the X-ray / movable unit controller 26, and the IVR simulator 35 are connected to the system controller 25.

  The X-ray / movable unit controller 26 radiates the movement amount of the C arm 16 and the bed 11 and the X-ray tube 31 via the C arm / bed mechanism control unit 27 when the operator operates the operation unit 12. For controlling the X-rays to be generated. The X-ray / movable unit controller 26 obtains angle information and the like from the X-ray / support unit control interface 42 in the system controller 25.

  The IVR simulator 35 is a device for simulating an IVR procedure by synthesizing and displaying a pseudo X-ray image based on patient image information and a situation where a pseudo catheter or pseudo IVR treatment device is simulated. Images and the like obtained in advance by the IVR simulator 35 are stored in the main database 44 via the simulator interface 48 in the system controller 25.

  In the video circuit 47, image processing is performed to display the image data obtained by the X-ray detection unit 15 on the image monitor 17. The surgeon can perform X-ray diagnostic treatment by operating the operation unit 12 while confirming the image displayed on the image monitor 17.

  In the X-ray diagnostic treatment apparatus 10 having such a configuration, an operator performs an imaging start operation using a switch (not shown) of the operation unit 12. Then, the operation signal from the operation unit 12 is processed by the system controller 25, and the movement amount of the C arm 16 and the bed 11 is controlled via the X-ray / movable unit control controller 26 and the C arm / bed mechanism control unit 27. Further, the high voltage generator 30 is controlled by the X-ray controller 29, and X-rays start to be emitted from the X-ray tube 31 in the X-ray generator 14 via the X-ray restrictor 32.

  The X-rays irradiated here pass through the subject 20 placed on the bed 11, and the transmitted X-rays enter the X-ray detector 33 in the X-ray detection unit 15. The transmitted X-rays incident on the X-ray detector 33 are converted into digital data by a data converter (not shown) by the system controller 25 in synchronization with the X-ray irradiation, and are temporarily stored in the memory 45 as image data. The stored image is processed by the video circuit 47 and displayed on the image monitor 17. At the same time, the display image is stored in the hard disk drive 43 as an image file.

  X-ray irradiation can be interrupted by the operation of the operation unit 12, thereby completing the imaging. Also, even if a preset shooting time has elapsed, shooting automatically ends.

(Sixth embodiment)
Next, a sixth embodiment of the present invention will be described.

  In the first to fourth embodiments described above, the example in which the reference image by the IVR simulator 35 and the information at the time of using the IVR simulator are displayed on the image monitor 17 and used effectively is described. In this embodiment, the support position where the image at the time of performing the procedure is obtained by the simulator is reproduced using the incidental angle information associated with the image.

  FIG. 13 is a flowchart for explaining the operation of the X-ray diagnostic treatment apparatus according to the sixth embodiment of the present invention.

  In step S51, simulation information by the IVR simulator 35 is stored. Here, an image of a procedure simulation using the IVR simulator 35 is stored in a hard disk drive (not shown) of the IVR simulator 35 in a predetermined format. Then, the image stored in the hard disk drive is converted into DICOM format by using a file converter of an IVR simulator (not shown).

  In step S55, the angle information of the reference image set in step S53 is used, and the shooting angle of the C arm 16 is reproduced by an auto angle function for reproducing the shooting angle of the collected image.

  For example, in order to effectively use simulation information, conventionally, it has been necessary to manually adjust the observation angle of the X-ray apparatus with the observation angle at the time of simulation by operating the support manually. Therefore, by using the auto angle function, the observation angle at the time of simulation can be reproduced in a short time and without trouble. Furthermore, information at the time of simulation can be used effectively.

  In addition to the first to sixth embodiments described above, the following examples can be considered.

  (1) Two or more of the first to sixth embodiments described above are arbitrarily combined and displayed simultaneously.

  There is a lot of information obtained from the IVR simulator, and it takes time to refer to it individually, but in this way, information about many procedures can be obtained at one time.

  (2) Successful examples such as catheter operation and treatment action are displayed on the simulation image.

  Conventionally, when approaching a difficult place, there was no choice but to deal with it by trial and error. Thus, referring to a successful example, an operator can imagine a catheter operation.

  (3) A failure example such as catheter operation or treatment action is displayed on the simulation image.

  In this way, for example, when it is desired to know the risk when the procedure fails, the operation when the procedure fails and the damage to the patient can be known without actually failing.

  (4) A simulation image is created using an IVR simulator during the procedure, and the result is captured and displayed.

  If you do this, you want to use the IVR simulator even in procedures that have not been pre-simulated, or use the latest simulation information acquired during the procedure as well as the information acquired during the simulation. In some cases, the latest IVR simulation information can be utilized by creating a simulation image using an IVR simulator installed in the operation room during the procedure, and capturing and displaying the result.

  (5) A function of converting a 3D image taken into the X-ray apparatus into a 2D image is added.

  For example, when it is desired to create an X-ray image (2D image) from a 3D image obtained from a CT or IVR simulator, the X-ray image is generated from the 3D image in this way, and compared and referenced. Becomes easier.

  Further, it is possible to display a list of images and information displayed on the image monitor 17 as shown in FIG.

  For example, FIG. 14A is an image type list selection display, which is a display example using characters, and FIG. 14B is an image type list selection display, which is a display example using images. FIG. 14C shows an example in which a comment-specific list is displayed. FIG. 14D is an example of a composite type list display. In this case, FIG. 14D is a list display in which FIGS. 14B and 14C are combined.

  These lists are read from information such as images and comments stored in the main database 44, and can be switched and selected while viewing on the image monitor 17 by a display switching button (not shown) in the operation unit 12. It is.

  Further, the list display described above may have the following functions.

  That is, (i) a function for sorting the display order of the display list shown in FIG. 14 from supporter position information and inspection status information. As this sort, for example, an image close to the current position is preferentially arranged, or an image close in time from the inspection elapsed time is preferentially arranged.

  In addition, (ii) a function of storing what has been used once and sorting it from the display order of the display list shown in FIG. For example, such sorting may be performed by lowering the display priority of items that have been used once, removing items that have been used once from the display list, and preferentially displaying items that have been used once.

  By providing such a sort function, it becomes easier for the surgeon to use.

  Although the embodiments of the present invention have been described above, the present invention can be variously modified without departing from the gist of the present invention other than the above-described embodiments.

  Further, the above-described embodiments include inventions at various stages, and various inventions can be extracted by appropriately combining a plurality of disclosed constituent elements. For example, even if some constituent requirements are deleted from all the constituent requirements shown in the embodiment, the problem described in the column of the problem to be solved by the invention can be solved, and the effect described in the column of the effect of the invention Can be extracted as an invention.
