Description

  Embodiments described herein relate generally to an X-ray diagnostic system.

  Conventionally, a mass screening has been carried out for a plurality of examinees (subjects). In this group examination, for example, an X-ray diagnostic apparatus is used for imaging a region such as a chest or stomach.

  In addition, mass screening of the stomach using an X-ray diagnostic apparatus is performed at each medical institution, and for example, a vehicle such as a bus equipped with an X-ray diagnostic apparatus goes to a place where many subjects gather. May also be implemented.

JP 2005-160929 A

  When a mass examination is performed, a medical worker who operates the X-ray diagnostic apparatus must take a large number of subjects within a limited time. In many cases, a region to be imaged is determined in advance, such as “chest screening” or “stomach screening”. Therefore, although there is no deviation as to where the position is in the body as long as it is a human being, the position differs depending on the subject even if it is called “chest” or “stomach”. For this reason, the medical staff must specify the position to be an imaging region for each subject and move the X-ray diagnostic apparatus to an appropriate position according to the position.

  However, in the case of a group medical examination in which a large number of subjects are photographed, it is very burdensome for medical staff to grasp an appropriate photographing position for each subject and move the apparatus.

  The present invention has been made in order to solve the above-mentioned problems, and the object of the present invention is to assure as much as possible the burden on the medical staff involved in appropriately grasping the imaging region and imaging the subject when imaging the subject. An object of the present invention is to provide an X-ray diagnostic system that can be reduced.

  According to a first aspect of the present invention, in the X-ray diagnostic system, when acquiring a diagnostic image of a subject, data on the height of the subject used for specifying an imaging region to be imaged is acquired. Therefore, based on the first sensor that measures the height of the subject and the height data acquired by the first sensor, the imaging region that is the target when imaging the subject is specified, and the imaging region And an X-ray diagnostic apparatus that automatically moves to the position and prepares for imaging.

It is a flowchart which shows the flow of utilization of the X-ray diagnostic system in embodiment.

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

  FIG. 1 is an overall view showing a scene where the X-ray diagnosis system S in the embodiment is actually used. The X-ray diagnostic system S includes at least a first sensor M and an X-ray diagnostic apparatus 1. The X-ray diagnostic system S in the embodiment of the present invention is installed in a medical institution, for example. As another form, for example, it may be mounted on a vehicle such as a bus and moved to a place where there are a large number of subjects to perform group examination.

  Furthermore, the X-ray diagnosis system S according to the embodiment of the present invention may be configured as an independent system, for example. For example, a hospital data management system (HIS: Hospital Information System), a radiation department data management system (RIS: Radiological Information System), medical image management system (PACS: Picture Archiving Communication System), etc. All of various management systems constructed in a medical institution, or a part thereof may be connected.

  When acquiring the internal data of the subject H, the first sensor M determines the height of the subject H in order to acquire the height data of the subject H used for specifying the imaging region to be imaged. Used to measure. As described above, the first sensor M measures the height of the subject H. For example, the first sensor M can be placed on the subject H by using an infrared sensor or the like after the subject H is placed at a predetermined position. It may be possible to measure height. In addition, any sensor may be used as the first sensor M as long as the height of the subject H can be measured.

  The X-ray diagnostic apparatus 1 specifies an imaging region that is an object when imaging the subject H based on the height data acquired by the first sensor M, and automatically sets the imaging site to the position of the imaging region. Move and prepare for shooting. For example, since the positions of the stomach and chest are roughly determined in the human body, if the height data of the subject H can be grasped, the position of the examination site to be imaged can be roughly grasped. Using this concept, the X-ray diagnostic apparatus 1 uses the height data of the subject H measured by the first sensor M to specify a part of the subject H to be imaged to some extent.

  The reason for specifying a certain degree is that the position of the imaging region for each subject H is slightly shifted, and in any case, the accurate location of the imaging region for the subject H is determined from the height data. Because it is not possible to grasp. Therefore, as will be described later, after the imaging system such as an X-ray tube is moved to a position to be an imaging region based on the height data, the medical staff may finely adjust the position.

  In the overall view shown in FIG. 1, the examination room R in which examination is performed is shown as seen from above. However, this examination room R may be provided in a medical institution or may be provided in a vehicle. The examination room R is composed of a preparation room R1 in which a subject H to be photographed enters and waits and a photographing room R2 in which photographing is actually performed.

  The preparation room R <b> 1 is a room where the subject H who has entered the room prepares and waits for imaging using the X-ray diagnostic apparatus 1. When the subject H enters the preparation room R1, the subject H stands at a predetermined position and measures the height. When the height measurement is performed and the height data of the subject H is acquired, for example, barium or the like is further drunk to prepare for photographing and wait. Then, the subject H waiting in the preparation room R1 is imaged in the imaging room R2. Therefore, since the subject H moves in the examination room R in this order, the subject H that has entered the preparation room R1 is hereinafter referred to as “subject H1” for convenience.

  In the preparation room R1, the height of the subject H1 is measured. This height measurement is performed by using the first sensor M. In the embodiment of the present invention, it is performed when the subject H1 entering the preparation room R1 stands on the wall parallel to the sliding door. The first sensor M measures the height of the subject H1 standing in front of it, and transmits the result to the X-ray diagnostic apparatus 1 as height data of the subject H1.

  The first sensor M is installed at the position shown in FIG. 1 in the embodiment of the present invention. However, if the height of the subject H1 can be measured, the first sensor M is installed in the preparation room R1. It may be provided at any position. Here, although the first sensor M uses one sensor, a plurality of sensors may be provided, for example, to measure the height of a plurality of subjects H1 simultaneously. good.

  The imaging room R2 is a room for imaging a desired part using the X-ray diagnostic apparatus 1. An X-ray diagnostic apparatus 1 that performs imaging using a bed B is shown in the imaging room R2 shown in FIG. However, the X-ray diagnostic apparatus 1 may be an apparatus that performs imaging while the subject H is lying on the bed B as described above, or may be in a standing position on the subject H. It may be an apparatus that performs photographing in a maintained state. Here, the subject H photographed in the photographing room R2 is represented as “subject H2” for convenience.

  In the imaging room R2 of FIG. 1, it is shown that imaging is performed with the subject H2 lying on the bed B. Further, since the examination room R is shown as an overhead view in FIG. 1, the X-ray generation unit 1k of the X-ray diagnostic apparatus 1 covers the subject H2 just in the region corresponding to the stomach of the subject H1. Looks like. Further, the bed B does not move, and the X-ray generator 1k and the like move in the height direction (longitudinal direction) of the subject H2, so that an appropriate imaging position is taken.

  FIG. 2 is a block diagram showing an internal configuration of the X-ray diagnostic system S including the X-ray diagnostic apparatus 1 according to the embodiment. The height data of the subject H1 measured by the first sensor M is transmitted to the X-ray diagnostic apparatus 1. Further, the X-ray diagnostic apparatus 1, for example, the X-ray generator 1 k is automatically driven on the basis of the obtained height data and moved to an appropriate position. It may be dangerous if H is present. Therefore, in the embodiment of the present invention, a second sensor N is provided for confirming that the subject H does not exist in the vicinity of the X-ray diagnostic apparatus 1 during the movement.

  In the X-ray diagnostic apparatus 1, a CPU (Central Processing Unit) 1a, a ROM (Read Only Memory) 1b, a RAM (Random Access Memory) 1c, and an input / output interface 1d are connected via a bus 1e. An input unit 1f, a display unit 1g, a communication control unit 1h, a storage unit 1i, and a drive unit control unit 1j are connected to the input / output interface 1d.

  The drive controller 1j includes an X-ray generator 1k that irradiates the subject H2 with X-rays, an X-ray detector 1l that detects X-rays transmitted through the subject H2, and a subject H2 during imaging. A lying bed B is connected. The drive unit control unit 1j drives and controls the X-ray generation unit 1k, the X-ray detection unit 1l, or the bed B based on, for example, imaging conditions input by the medical staff using the input unit 1f. The bed B has a function of detecting whether or not the subject H2 is placed, and information regarding the presence or absence of the subject H1 is transmitted to the CPU 1a via the drive unit control unit 1j.

  Further, here, only the three drive units connected to the drive unit control unit 1j are described above, but other drive units included in the normal X-ray diagnostic apparatus 1 are merely omitted. Of course, the X-ray diagnostic apparatus 1 is provided.

  The CPU 1a reads out and executes a boot program for starting up the X-ray diagnostic apparatus 1 from the ROM 1b based on an input signal from the input unit 1f, and reads out various data stored in the storage unit 1i. The CPU 1a controls various devices based on input signals from other external devices not shown in FIG. 2 via the input unit 1f and the input / output interface 1d.

  Further, the CPU 1a reads a program and data stored in the RAM 1c, the storage unit 1i, and the like, loads them into the RAM 1c, and performs processing for setting shooting conditions and image generation based on a command of the program read from the RAM 1c. A processing device that implements a series of processing such as processing, data calculation, and processing.

  The input unit 1f is configured by an input device such as a keyboard and a dial for an operator of the X-ray diagnostic apparatus 1 (for example, a medical worker such as a medical radiographer) to input various operations, and is based on the operation of the operator. An input signal is generated and transmitted to the CPU 1a via the bus 1e.

  The display unit 1g is a liquid crystal display, for example. The display unit 1g receives an output signal from the CPU 1a via the bus 1e and, for example, an image necessary for setting a condition when performing a processing request for an image to the X-ray diagnostic apparatus 1, or a processing result of the CPU 1a. Etc. are displayed.

  The communication control unit 1h is a means such as a LAN card or a modem, and is a means that enables the X-ray diagnostic apparatus 1 to be connected to a communication network (not shown) such as the Internet or a LAN. Data transmitted / received to / from the communication network via the communication control unit 1h is transmitted / received to / from the CPU 1a via the input / output interface 1d and the bus 1e as input signals or output signals. Further, information (data) from the first sensor M and the second sensor N constituting the X-ray diagnostic system S is input to the X-ray diagnostic apparatus 1 via the communication control unit 1h.

  Here, the “second sensor N” detects that the preparation for imaging has been completed and the subject H1 has entered the imaging room R2, or that the imaging has ended and the subject H2 has exited the imaging room R2. It is a sensor. As for the second sensor N, any sensor may be used as long as the entrance / exit of the subject H into the imaging room R2 can be grasped.

  The storage unit 1i is composed of a semiconductor or a magnetic disk, and stores programs and data executed by the CPU 1a.

  Next, the flow of examination will be described along the movement of the subject H in the examination room R when the group examination is performed. 3 to 6 are flowcharts showing the flow of use of the X-ray diagnostic system S in the embodiment.

  First, when a medical examination is started, the first sensor M checks whether or not the subject H is waiting at a predetermined position in the preparation room R1 (ST1 in FIG. 3). The “subject H” here is represented as “subject H1” for convenience as described above. Here, the “predetermined position” indicates a position suitable for measuring the height of the subject H1 using the first sensor M. In the preparation room R1 shown in FIG. 1, the front of the first sensor M and the front of the wall on which the door for entering the preparation room R1 is provided are “predetermined positions”.

  The height of the subject H1 entering the preparation room R1 is measured by the first sensor M. Therefore, if the subject H1 does not stand at a position where the height of the subject H1 can be measured by the first sensor, the measurement cannot be performed. Therefore, the measurement of the height of the subject is on standby until the preparation for measurement is completed, that is, until the subject H1 stands at a predetermined position (NO in ST1). Actually, the subject H1 stands (waits) at a predetermined position based on his / her own judgment or guidance by a medical worker.

  When the first sensor M confirms that the subject H1 has stood at a predetermined position (YES in ST1), the first sensor M measures the height of the subject H1 (ST2). The height data of the subject H1 acquired by the measurement is input to the X-ray diagnostic apparatus 1 via the communication control unit 1h. In addition, the X-ray diagnostic apparatus 1 specifies an imaging region based on the input height data of the subject H1 (ST3).

  In the flowchart shown in FIG. 3, it has been described that the first sensor M acquires the height data by measuring the height of the subject H1. However, the method of acquiring the height data is not limited to this method. For example, a method described using the flowchart shown in FIG. 4 can also be adopted.

  That is, as described above, the X-ray diagnostic apparatus 1 is connected to the communication network via the communication control unit 1h. Here, examples of the communication network include a network such as a LAN (Local Area Network) and the Internet. In addition, the standard related to information exchanged via the communication network may be any standard such as DICOM (Digital Imaging and Communication in Medicine).

  For example, the HIS described above stores various information related to the subject H to be imaged. The information stored here includes not only the case of the disease but also patient information of the subject H, for example, and also includes the height data. Therefore, if the height data stored in advance is acquired separately in this way, the subject H1 does not have to be measured using the first sensor M in the preparation room R1. H1 height data can be acquired.

  In this case, the medical staff uses the input unit 1f (not shown) to identify the subject H1 who has entered the preparation room R1 (ST21). In specifying the subject H1, for example, a name, date of birth, or patient ID assigned to the subject H1 can be used. After the subject H1 to be acquired is identified, the X-ray diagnostic apparatus 1 further sends an acquisition request for the height data to the device storing the height data via the communication network. (ST22). The device in which the height data is stored may be any device, for example, a device constituting the HIS or a server connected to a communication network.

  The X-ray diagnostic apparatus 1 issues an acquisition request and waits until desired data can be acquired (ST23). If the height data related to the subject H1 can be acquired (YES in ST23), the position of the part to be imaged for the subject H1 is then specified using the height data (FIG. 3). ST3).

  Here, the part is specified as follows, for example. As described above, the position of a part such as the stomach or chest in the human body is not increased. Therefore, it is considered that the position of the stomach or chest in height can be roughly grasped statistically, for example. However, for example, the height (position) from the foot differs depending on whether the height is high or low. Therefore, from the data indicating the relationship between the height and the position of each part such as the stomach and chest that are the imaging region, the approximate position of the imaging region is grasped from the height data of the subject H to be imaged. Can be considered.

  Therefore, the X-ray diagnostic apparatus 1 specifies the position of the imaging region using the grasped height data of the subject H1. It is assumed that the data indicating the relationship between the height and the position of the imaging region used here is stored in, for example, the storage unit 1i or, for example, a server connected via a communication network.

  When the specification of the position to be an imaging region for the subject H1 is completed, the X-ray diagnostic apparatus 1 checks whether or not the subject H1 is the first imaging target (ST4). Here, the “first imaging object” may be the first imaging after the X-ray diagnostic apparatus 1 is turned on, or may be the first imaging of the day. Such a determination is made because it is necessary to determine whether or not the subject H2 is in the imaging room R2.

  That is, as described above, in the embodiment of the present invention, the second sensor N is provided in the imaging room R2, and it is confirmed whether or not the subject H2 exists in the imaging room R2. This is because the positioning of the X-ray diagnostic apparatus 1 is automatically performed based on the measured or acquired height data of the subject H1, and the X-ray diagnostic apparatus 1 is automatically driven (moved). This is because it is necessary to give sufficient consideration to safety so that the subject H2 does not come into contact with the X-ray diagnostic apparatus 1.

  As a result of confirming whether or not the subject H1 is the first imaging target, the X-ray diagnostic apparatus 1 determines that it is not the first imaging (NO in ST4), first, the previous subject H, that is, It is confirmed whether or not the subject H2 for which imaging has been completed has left the X-ray diagnostic apparatus 1 (ST5). Here, whether or not the subject H2 has left the X-ray diagnostic apparatus 1 can be confirmed by, for example, determining whether or not the subject H2 has descended from the bed B.

  When the subject H2 is placed on the bed B, for example, if the X-ray generator 1k is moved based on the height data relating to the subject H2 currently in the preparation room R1, which is imaged next, It does not necessarily happen that the X-ray generation unit 1k is brought into contact with the specimen H2. Therefore, in order to avoid such inconvenience, it is confirmed whether or not the subject H2 for which imaging has been completed is not in the vicinity of the X-ray diagnostic apparatus 1. As a result, when it is determined that the subject H2 is not separated from the X-ray diagnostic apparatus 1 (NO in ST5), the X-ray diagnostic apparatus 1 is in a stand-by state.

  If the safety of the subject H2 is further ensured, the subject H2 is separated from the X-ray diagnostic apparatus 1 unless the second sensor N receives a report that the subject H2 has left the imaging room R2. You may make it judge that it is not.

  In the embodiment of the present invention, as shown in FIG. 1, the second sensor N is provided in two locations near the door of the photographing room R2. That is, one second sensor N1 is provided at a position closest to the door, and the other second sensor N2 is provided at a position facing one second sensor N1. Then, one second sensor N1 and the other second sensor N2 are connected with infrared rays, and the subject H2 leaves the imaging room R2 when the infrared rays are blocked, or the subject H1 enters the imaging room R2. Can be judged to have entered the room.

  Usually, in the imaging room R2 in which the X-ray diagnostic apparatus 1 is installed, the subject H1 that is the next imaging target is the imaging room R2 unless the subject H2 that was the imaging target exits after imaging. Is not expected to enter the room. Therefore, the subject H2 whose imaging has been completed is performed by confirming whether or not the subject H2 is placed on the bed B and confirming whether or not the second sensor N has detected exit of the subject H2. Is present in the vicinity of the X-ray diagnostic apparatus 1.

  When it is determined that the subject H2 is away from the X-ray diagnostic apparatus 1 based on one or both of the detection by the bed B, the detection by the second sensor N (YES in ST5), X-rays The diagnostic apparatus 1 further checks whether or not the next subject H has approached the X-ray diagnostic apparatus 1 (represented as “apparatus” in the flowchart of FIG. 3) (ST6). Here, the “next subject H” is the subject H1 prepared for the next imaging in the preparation room R1. That is, it is determined here whether or not the subject H1 has entered the imaging room R2.

  The determination as to whether or not the subject H1 has entered the imaging room R2 is made based on the information sent from the second sensor N. Usually, after imaging is completed and the subject H2 leaves the imaging room R2, the subject H1 to be imaged next enters the imaging room R2.

  As described above, if the subject H1 or the subject H2 is present in the radiographing room R2 in which the X-ray diagnostic apparatus 1 is installed, it is necessary to ensure the safety thereof. It is not possible to move the position of the X-ray diagnostic apparatus 1 before imaging the subject H1 using the height data of the subject H1. That is, after confirming that the imaging room R2 is in an unattended state, for example, the X-ray generator 1k of the X-ray diagnostic apparatus 1 is moved.

  Therefore, after confirming that the subject H2 has moved away from the X-ray diagnostic apparatus 1, the subject H1 has not further approached the X-ray diagnostic apparatus 1 (the subject H1 has not yet entered the imaging room R2). The X-ray diagnostic apparatus 1 is moved during this period. Accordingly, when the subject H2 that has completed imaging has left the X-ray diagnostic apparatus 1 and then enters the imaging room R2 and approaches the X-ray diagnostic apparatus 1 (YES in ST6), The X-ray diagnostic apparatus 1 is in a standby state without performing alignment processing to a position to be an imaging region.

  If the subject H2 leaves the imaging room R2 (YES in ST5), but the subject H1 does not enter the imaging room R2 from the preparation room R1 (NO in ST6), then the subject H1 takes an image. The subject H does not exist in the imaging room R2 until it enters the room R2. Therefore, in order to move the X-ray diagnostic apparatus 1 during this period, the X-ray diagnostic apparatus 1 receives information related to the position of the imaging region specified from the height data related to the subject H1 to be subjected to the next imaging, and is driven. It transmits to the part control part 1j (ST7).

  Thus, the drive unit control unit 1j can move, for example, the X-ray generation unit 1k to the position of the imaging region in order to image the subject H1 next. Therefore, the drive unit control unit 1j moves, for example, the X-ray generation unit 1k based on the received information on the position of the imaging region (ST8 in FIG. 5). As described above, since there is no subject H in the imaging room R2 in this state, even if each part of the X-ray diagnostic apparatus 1 is moved, there is no inconvenience such as contact with the subject H, for example.

  Note that, for example, the X-ray generation unit 1k and the bed B are objects to be moved by the drive unit control unit 1j. The moving direction is the height direction of the subject H. In addition, in the case of the X-ray diagnostic apparatus 1 that includes the bed B and the subject H needs to lie down at the time of imaging, the X-ray generator 1k and the like move in the horizontal direction with respect to the ground plane of the X-ray diagnostic apparatus 1 Will do. On the other hand, in the case of the X-ray diagnostic apparatus 1 that performs imaging while the subject H is standing, the position is set by, for example, the X-ray detection unit 11 moving up and down in the vertical direction.

  The X-ray diagnostic apparatus 1 confirms, for example, whether or not the X-ray generation unit 1k has moved to an appropriate position based on the measurement or acquired height data of the subject H1 (ST9). If it has not moved, the drive part control part 1j will continue a movement until it moves to the position made into an appropriate position (NO of ST9). On the other hand, when it is determined that the X-ray generator 1k or the like has moved to an appropriate position from the measured or acquired height data (YES in ST9), the subject H2 (the subject in the preparation room R1) When the specimen H1 enters the photographing room R2 and is photographed, photographing of the subject H1 becomes the subject H2) (ST10).

  This automatic alignment is performed when the height data of the subject H2 to be imaged is measured or acquired in advance and the X-ray diagnostic apparatus 1 is automatically moved to a position suitable for imaging. If the shooting position is surely done, it will never be over.

  However, even if the position of the X-ray diagnostic apparatus 1 is aligned based on the height data of the subject H2, for example, when the subject H2 is lying on the bed B, for example, the position where the alignment is performed is not necessarily the position of imaging. In some cases, it is not optimal. Therefore, it is of course possible for the medical staff to finely adjust the imaging position before the imaging is started after the X-ray generator 1k of the X-ray diagnostic apparatus 1 is moved. In this case, the subject H2 to be actually imaged is brought close to the X-ray diagnostic apparatus 1 so as to take a posture suitable for imaging, and then a medical worker manually generates X-rays at an optimal position for the imaging position. Move part 1k and the like.

  Up to this point, a general method has been described for automatic alignment of the X-ray imaging apparatus 1 based on height data. Next, as a modification, for example, a case where a footrest plate is provided on the bed B will be described. Here, the “footrest plate” is a plate on which the subject H2 lying on the bed B makes contact with the foot. For example, the bed B moves not only in a position parallel to the installation surface but also in the vertical direction, for example. If possible, it is a plate used by the subject H2 for footrest. By providing this plate, the subject H2 can stand on the footrest plate when the bed B is perpendicular to the installation surface.

  When the footrest plate is provided, the footrest plate is used for automatic alignment of the X-ray imaging apparatus 1 based on height data. In other words, if the subject H2 is placed on the footrest plate with the sole of the foot, the height data of the subject H2 to be imaged can be fully utilized with the footrest plate as a base point. That is, if the footrest plate is set to 0 cm and the height data is applied from here, the position of the part to be imaged that has already been determined can be grasped more accurately, and the X-ray generator 1k of the X-ray diagnostic apparatus 1 and the like. Can be appropriately moved to the position to be imaged. In this way, it is considered that the number of scenes where further fine adjustment by the medical staff is not necessary thereafter increases, so that the burden on the medical staff can be further reduced.

  FIG. 6 is a flowchart showing a flow of use of the X-ray diagnostic system S in the embodiment. The flowchart shown in FIG. 6 is connected to the flowchart shown in FIG.

  After measuring or acquiring the height data of the subject H2 to be imaged, the subject H2 that has been imaged so far leaves the imaging room R2, while the subject H1 in the preparation room R1 Preparation for movement of the X-ray diagnostic apparatus 1 is performed in a state where the imaging room R2 is not yet entered (ST1 to ST6 in FIG. 3). In the X-ray imaging apparatus 1, position information relating to the specified imaging region is received by the drive unit control unit 11 (ST 7 in FIG. 3). Next, it is confirmed by the medical staff whether or not the footrest plate has been moved in accordance with the subject H2 to be imaged next (ST31 in FIG. 6).

  Depending on the height of the subject H2, it is necessary to perform imaging at a more appropriate position on the bed B. At that time, the X-ray diagnostic apparatus 1 is appropriate if the footrest plate is moved from the position where the subject H2 is lying to an appropriate position and the subject H2 is lying down in contact with the footrest plate. It is possible to move to a proper shooting position. Therefore, as described above, the medical staff moves the position of the footrest plate according to the subject H2. The X-ray diagnostic apparatus 1 is in a standby state until the medical worker moves the footrest board (NO in ST31).

  When the X-ray diagnostic apparatus 1 recognizes that the footrest plate has been moved (YES in ST31), the drive unit control unit 11 performs the X-ray generation unit 1k or the like based on the received information on the position of the imaging region. Is moved (ST8). Thereafter, after it is confirmed whether or not the X-ray generator 1k or the like has moved to an appropriate position (ST9), imaging of the subject H2 is started (ST10). Here, the subject H2 is naturally lying on the bed B so that the sole of the foot is brought into contact with the footrest plate.

  Of course, there is a case where it is not necessary to move the footrest plate. In that case, the X-ray diagnostic apparatus 1 knows that the medical staff has not moved the footrest plate. Although not shown in the flowchart of FIG. 6, in this case, after the X-ray diagnostic apparatus 1 checks that the footrest plate is not moved, the received imaging is performed on the basis of the position of the footrest plate that does not move. Based on the information on the position of the part, the drive unit control unit 11 moves the X-ray generation unit 1k and the like to perform imaging.

  Further, when there is no footrest plate, if a reference position on the bed B is determined in advance, the X-ray generator 1k of the X-ray diagnostic apparatus 1 and the like using the height data based on the position is used. Can be moved. At the same time, by aligning the position of the foot of the subject H2 lying on the bed B with the position, the X-ray generation unit 1k after the movement can be moved to the position of the imaging region on the subject H2.

  As described above, imaging of the subject is performed by automatically moving the X-ray diagnostic apparatus to a position suitable for imaging using the height data of the subject to be measured or acquired in advance. Therefore, it is possible to provide an X-ray diagnostic system capable of reducing as much as possible the burden on the medical staff accompanying the proper grasp of the imaging region and the alignment of the apparatus.

  In addition, when a footrest plate or the like is provided, the position serving as a reference for the measured height data is clarified, so that more appropriate alignment can be performed.

  Although an embodiment of the present invention has been described, this embodiment is presented as an example and is not intended to limit the scope of the invention. For example, heretofore described the example based on the position of the subject's foot in order to identify the position of the part to be imaged in the subject, such as the use of a footrest plate, the use of height data In this case, instead of placing the reference on the foot, for example, the position of the imaging part may be grasped on the basis of the head of the subject.

  This embodiment can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the spirit of the invention. This embodiment and its modifications are included in the scope and gist of the invention, and are included in the invention described in the claims and the equivalents thereof.
