Description

  Embodiments described herein relate generally to an IP reader and an X-ray diagnostic apparatus.

  There are the following methods for obtaining an X-ray image of a subject. 1) A method of copying an X-ray transmission image on a film coated with a photosensitive agent (hereinafter referred to as FS (Film Screen)); (Referred to as IP (Imaging Plate)) is read by a laser scanner, converted into a digital signal, and an image is obtained (hereinafter referred to as CR (Computed Radiography)), 3) X-rays are absorbed by a phosphor, A method of obtaining an image by FPD (Flat Panel Display) by converting the generated light into electric charge by a photodiode and converting it into a digital signal corresponding to the electric charge (hereinafter referred to as DR (Digital Radiography)). Note that if the DR is interpreted broadly, the CR also belongs to the DR. Here, the imaging method using the IP is referred to as CR, and the imaging method using the FPD is referred to as DR.

  Conventionally, in imaging with FS and CR, after X-ray imaging, development processing and scanning processing are necessary, respectively, so that the imaging results cannot be confirmed immediately on the spot. On the other hand, in DR using FPD, the result can be confirmed with an image immediately after shooting. However, since the FPD is more expensive than the IP or the like, there is a problem that the cost burden is large due to the introduction of a photographing set using the FPD.

  An object of the present invention is to provide an IP reading apparatus and an X-ray diagnostic apparatus that can confirm an X-ray image on the spot immediately after X-ray imaging.

The IP reading apparatus according to the present embodiment includes an IP reading unit that reads X-ray information about a subject from an IP, a storage unit that stores the IP reading unit, an IP support mechanism that supports the IP movably, and the IP In order to enable the insertion / extraction of the X-ray image with respect to the subject based on an output from the IP reading unit and an IP driving unit that drives the IP support mechanism A display unit for displaying the X-ray image;

(First embodiment)
The IP reader according to the first embodiment will be described below with reference to the drawings. In the following description, components having substantially the same function and configuration are denoted by the same reference numerals, and redundant description will be given only when necessary.

  FIG. 1 is a block diagram illustrating an example of the configuration of the IP reader 1 according to the first embodiment. As shown in FIG. 1, the IP reading apparatus 1 according to the first embodiment includes an IP reading unit 11, a storage unit 12, an IP support mechanism 13, an IP drive unit 14, an image generation unit 15, an image processing unit 16, and display control. Section 17, display section 18, input section 19, IP control section 20, and storage section 21.

  The IP reading device 1 described in the first embodiment is a device that reads an imaging plate (hereinafter referred to as IP). The IP is, for example, a plate in which a special phosphor having a memory function called a stimulable phosphor is formed into a sheet shape. When X-rays are irradiated to the IP, the radiation energy corresponding to the transmitted subject is accumulated in the IP.

  The IP reading unit 11 reads X-ray information related to the subject from the IP. The IP reading unit 11 includes a laser scanning unit, a photodetector, an A / D converter, and a sub scanning unit. The laser scanning unit includes a laser light source for scanning IP and an optical deflector such as a polygon mirror. The laser scanning unit scans the IP with a laser beam. Then, IP generates stimulated light emission according to the radiation energy. The photodetector detects the stimulated emission generated from the IP and converts it into an electrical signal. The A / D converter converts an electrical signal from the photodetector into a digital signal. The converted digital signal is output to the image generation unit 15 described later.

  In addition, the IP reading unit 11 erases the X-ray information included in the IP. Specifically, the IP reading unit 11 applies visible light having a long wavelength to the IP. Then, the radiation energy accumulated in the IP is emitted as short wavelength light. As described above, the X-ray information included in the IP is erased.

  The accommodating part 12 accommodates at least the IP reading part 11. The accommodating part 12 has a box shape, for example. However, the storage unit 12 may have other structures and shapes as long as the IP stored in the storage unit 12 is not exposed to natural light, infrared light, fluorescent light, or the like. The accommodating part 12 has a slit for allowing IP to be taken in and out of the accommodating part 12. The slit may have another structure as long as the IP can be taken in and out of the accommodating portion 12. For example, the accommodating part 12 may have an opening / closing part 121 in a part thereof. The opening / closing part 121 is opened and closed by an opening / closing drive part (not shown), so that the IP accommodated in the accommodation part 12 can be taken in and out. The structure of the accommodating part 12 having the slit and the structure of the accommodating part 12 having the opening / closing part 121 will be described later.

The IP support mechanism 13 supports the IP in a movable manner. The IP support mechanism may be a structure that supports a plurality of IPs.
The IP drive unit 14 drives the IP support mechanism 13 in order to take out the IP stored in the storage unit 12 from the storage unit 12. A state in which the IP is accommodated in the accommodation unit 12 is referred to as a standby state of the IP reader 1. In addition, the IP support mechanism 13 is driven in order to accommodate the IP in a state of being taken out from the accommodation unit 12 in the accommodation unit 12. The state where the IP is taken out from the storage unit 12 is referred to as a photographing state of the IP reading device 1. The IP drive unit 14 drives the IP support mechanism 13 in accordance with a user instruction via the input unit 19. The IP drive unit 14 may automatically drive the IP support mechanism 13 when the X-ray imaging of the subject is completed. In order to determine whether the X-ray imaging of the subject has been completed, the IP reader 1 may include an X-ray detection unit that detects X-rays. The X-ray detection unit is provided in the IP support mechanism 13, for example. However, the X-ray detection unit may be provided at another position as long as the X-ray irradiated to the subject can be detected in the imaging state. For example, the X-ray detection unit may be provided on a part of the storage unit 12, for example, on the outer surface. The IP control unit 20 described later determines whether the X-ray imaging has been completed based on output data from the X-ray detection unit. Specifically, the IP control unit 20 compares the X-ray detection value of the X-ray detection unit with a threshold value. For example, the IP control unit 20 specifies the timing at which the X-ray detection value by the X-ray detection unit is larger than the threshold as the timing at which X-ray imaging is started. Then, the timing when the X-ray detection value by the X-ray detection unit becomes equal to or less than the threshold is specified as the timing when the X-ray imaging is finished. The IP control unit 20 outputs an imaging end signal notifying the end of X-ray imaging to the IP driving unit 14. The IP driving unit 14 receives the shooting end signal from the IP control unit 20 or receives the shooting end signal from the IP control unit 20, and drives the IP support mechanism 13 after a predetermined time has elapsed. Then, the IP is accommodated in the accommodating portion 12.

  Note that the IP support mechanism 13 is configured to support a plurality of IPs, and when shifting from the standby state to the photographing state, the IP drive unit 14 accommodates one IP from which data has been deleted among the plurality of IPs. The IP support mechanism is driven so as to come out from the unit 12.

  The image generation unit 15 generates X-ray image data related to the subject based on the output data from the IP reading unit 11. The pixel value assigned to each pixel constituting the X-ray image is a value corresponding to the X-ray attenuation coefficient related to the substance on the X-ray transmission path in the subject.

  The image processing unit 16 performs image processing on the X-ray image data generated by the image generation unit 15. The image processing here includes, for example, gradation conversion processing for manipulating the contrast of an X-ray image, smoothing processing for removing noise, sharpening processing for enhancing edges, and the like. Among these image processing, the image processing executed by the image processing unit 16 and its parameters are determined by the user.

  The display control unit 17 sends an image signal to the display unit 18 based on the X-ray image data generated by the image generation unit 15 or the X-ray image data after the image processing is executed by the image processing unit 16. Output. The display unit 18 displays an X-ray image according to the image signal from the display control unit 17. Note that the IP reading device 1 according to the first embodiment includes a display unit 18. However, the IP reader 1 according to the first embodiment may not include the display unit 18 as long as the X-ray image can be displayed immediately. For example, the display control unit 17 may output an image signal to an external display.

  The input unit 19 functions as an interface for inputting instruction information from the operator to the IP reading device 1. The input unit 19 includes input devices such as a mouse and a keyboard, for example. Note that a trackball, a touch panel, a switch, or the like may be used as the input device. The operator can input, for example, an instruction relating to setting of IP movement conditions, setting of the type of image processing to be executed, and setting of parameters of image processing to the IP reading device 1 via the input unit 19. . The IP movement condition is, for example, a condition regarding whether or not the IP is automatically accommodated at the same time as the movement speed of the IP and the X-ray imaging.

  The IP control unit 20 includes a CPU (Central Processing Unit) and a memory circuit. The IP control unit 20 receives the information input from the input unit 19 and temporarily stores the input information in the memory circuit. Then, the IP control unit 20 controls each unit of the IP reading device 1 based on this input information. Specifically, the IP control unit 20 controls the IP reading process by the IP reading unit 11. For example, the IP control unit 20 controls the IP reading unit 11 so that the IP reading process of the IP reading unit 11 is executed when the captured IP is stored in the storage unit 12. Further, the IP control unit 20 controls the IP reading unit 11 so that IP data erasure of the IP reading unit 11 is executed in accordance with a user instruction via the input unit 19.

  The storage unit 21 is a semiconductor storage device such as a flash SSD (Solid State Disk) that is a semiconductor storage element, an HDD (Hard Disk Drive), or the like. The storage unit 21 stores X-ray image data, IP movement condition data, and image processing condition data in accordance with control by the IP control unit 20. The data stored in the storage unit 21 can be appropriately deleted according to a user instruction via the input unit 19.

Hereinafter, the appearance of the IP reading apparatus 1 according to the first embodiment will be described with reference to FIGS. 2A, 2B, 3A, and 3B.
FIG. 2A is a diagram illustrating an appearance of a first example of the IP reading device 1 according to the first embodiment in a standby state.
FIG. 2B is a diagram illustrating an external appearance of the first example of the IP reading device 1 according to the first embodiment in a photographing state.
As shown in FIG. 2A, the accommodating portion 12 of the first example (hereinafter, referred to as the IP reading device 1 of the first example) of the IP reading device 1 according to the first embodiment has a slit. The accommodating portion 12 includes an input portion 19 and a display portion 18 in a part thereof. In the standby state, the IP reading device 1 of the first example stores the IP in the storage unit 12. Then, when the standby state is switched to the photographing state, the IP reading device 1 of the first example puts out the IP from the accommodating portion 12 as shown in FIG. 2B. Specifically, the IP drive unit 14 is driven by the IP control unit 20, and the IP is slid out of the housing unit 12 together with the IP support mechanism 13.

FIG. 3A is a diagram illustrating an appearance of a second example of the IP reading device 1 according to the first embodiment in a standby state.
FIG. 3B is a diagram illustrating an appearance of a second example of the IP reading device 1 according to the first embodiment in a photographing state.
As illustrated in FIG. 3A, the accommodating unit 12 of the second example (hereinafter, referred to as the IP reader 1 of the second example) of the IP reading device 1 according to the first embodiment includes an opening / closing unit 121. Moreover, the accommodating part 12 has the input part 19 and the display part 18 in the part. In the standby state, the IP reading device 1 of the second example stores the IP in the storage unit 12. At this time, the opening / closing part 121 is closed. Therefore, IP is not sensitive.
As shown in FIG. 3B, when the standby state is switched to the photographing state, the IP reading device 1 of the second example outputs the IP from the storage unit 12. Specifically, the IP drive unit 14 is driven by the IP control unit 20, the opening / closing unit 121 is opened, and the IP is taken out from the housing unit 12 together with the IP support mechanism 13. In the shooting state, the opening / closing part 121 is closed. Thereby, since IP is supported by IP support mechanism 13 and opening-and-closing part 121, it is stabilized.

Next, the IP support mechanism 13 according to the first embodiment will be described with reference to FIGS. 4A and 4B.
FIG. 4A is a diagram illustrating a first example of the IP support mechanism 13 of the IP reading device 1 according to the first embodiment.
FIG. 4B is a diagram illustrating a second example of the IP support mechanism 13 of the IP reading device 1 according to the first embodiment.

  As shown in FIG. 4A, the first example of the IP support mechanism 13 of the IP reader 1 according to the first embodiment (hereinafter referred to as the IP support mechanism 13 of the first example) is different from the IP support mechanism 13. In order to fix the IP, for example, it has a structure sandwiching the IP. Specifically, as shown in FIG. 4A, the IP support mechanism 13 of the first example has a structure that sandwiches two opposite sides of the four sides of the IP. However, the IP support mechanism 13 of the first example may have a structure sandwiching another position as long as the IP can be fixed to the IP support mechanism 13. For example, the IP support mechanism 13 of the first example may have a structure that sandwiches four corners of the IP, or may have a structure that sandwiches one side of the IP. The IP support mechanism 13 of the first example may be fixed by a method other than sandwiching the IP as long as the IP can be fixed to the IP support mechanism 13. As shown in FIG. 4B, the IP support mechanism 13 may be a tray as in the second example of the IP support mechanism 13 of the IP reader 1 according to the first embodiment. The IP support mechanism 13 fixes the IP to the IP support mechanism 13 by placing the IP on the tray.

  Next, a procedure for imaging a subject using the IP reader 1 of the first example and the second example will be described with reference to FIGS. 5A, 5B, and 5C, respectively.

FIG. 5A is a diagram illustrating an example of an imaging posture of a subject using the first example of the IP reading device 1 according to the first embodiment.
FIG. 5B is a diagram illustrating a first example of the imaging posture of the subject using the second example of the IP reading device 1 according to the first embodiment.
FIG. C is a diagram illustrating a second example of the imaging posture of the subject using the second example of the IP reading device 1 according to the first embodiment.
5A, 5B, and 5C illustrate a state in which the subject placed on the bed apparatus 2 is imaged by the X-ray diagnostic apparatus 4. FIG. The IP reader 1 is arranged so that the IP of the IP reader 1 in the imaging state faces the X-ray diagnostic apparatus 4. As described above, the method of arranging the IP reading device 1 includes a method in which the user directly arranges the IP reading device 1 or a method in which the IP reading device 1 is automatically arranged according to a user operation via the input unit 19. is there.

  As shown in FIG. 5A, the user moves the subject to the imaging position of the IP reader 1 of the first example. The subject is covered with an anti-static cloth or the like for preventing IP exposure. Then, the IP is issued from the storage unit 12 by a user operation via the input unit 19. Thus, the IP reading device 1 of the first example changes from the standby state to the photographing state. When the user finishes imaging of the subject, the user stores the IP in the storage unit 12 via the input unit 19. At this time, the IP reading device 1 of the first example may automatically store the IP in the storage unit 12 when the imaging of the subject ends. When the IP is stored in the storage unit 12, the IP reading unit 11 reads X-ray information about the subject from the IP. Based on the output data from the IP reading unit 11, X-ray image data relating to the subject is generated by the image generation unit 15. The image processing unit 16 executes image processing according to a user instruction or preset image processing on the X-ray image data. Thus, an X-ray image relating to the subject is displayed on the display unit 18. Then, data is erased from the IP according to a user instruction via the input unit 19. The IP from which data has been erased is used repeatedly.

  The shooting procedure described in FIG. 5A is the same as in FIGS. 5B and 5C. As shown in FIG. 5C, when the couchtop 2 or a part of the couchtop is made of CFRP (Carbon Fiber Reinforced Plastic), the IP reader 1 of the second example is The opening / closing part 121 may not be included in the constituent elements. That is, the opening / closing part 121 may be in an open state. CFRP has good X-ray transmittance. Therefore, as shown in FIG. 5C, the IP reading device 1 can detect X-rays that have passed through the subject by holding the IP at a position facing the X-ray diagnostic device 4 with the top plate interposed therebetween. On the other hand, CFRP is difficult to transmit visible light or the like that causes IP to be exposed. At the time of imaging, the subject is covered with an antistatic cloth or the like. For this reason, as shown in FIG. 5C, the IP reader 1 is arranged immediately below the top plate made of CFRP, so that IP is not exposed even during photographing. Therefore, when the IP reader 1 of the second example is arranged as shown in FIG. 5C, the IP reader 1 of the second example may not include the opening / closing part 121 as a component.

According to the IP reader 1 according to the first embodiment described above, the following effects can be obtained.
The IP reading device 1 according to the first embodiment has a structure that supports IP in a movable manner. Then, it is possible to shift from the standby state in which the IP is accommodated to the imaging state in which the IP is issued in accordance with a user instruction. Then, after the X-ray imaging of the subject is completed, the IP is accommodated in the accommodating unit 12 according to the user instruction, and the IP reading process is executed. Then, X-ray image data can be generated based on the X-ray information regarding the subject read from the IP, and the X-ray image can be displayed on the display unit 18 of the IP reading device 1 or an external display. . That is, the user can confirm an X-ray image related to the subject on the spot immediately after X-ray imaging in a CR using IP that is less expensive than FPD. Furthermore, the IP reading apparatus 1 can detect that the X-ray imaging on the subject has been completed, and automatically store the IP in the storage unit 12. This eliminates the need for an IP accommodating operation by the user each time shooting is completed. Therefore, the efficiency of diagnosis and treatment by the user can be improved. In the imaging state, the patient is placed on the exposed IP. Since the IP is thinner than a cassette with a built-in IP, for example, even if the IP is inserted under the patient's waist, the patient can take a picture without feeling uncomfortable. Thereby, the physical burden relevant to a patient's X-ray imaging can be reduced.
