Description

  Embodiments described herein relate generally to a medical diagnostic apparatus.

  In recent years, with the development of wireless communication technology, data is also transmitted and received by wireless communication in medical diagnostic apparatuses. For example, in a general X-ray imaging apparatus, X-ray detection data temporarily stored in a buffer in an FPD (Flat Panel Detector) is moved away from the FPD by wireless communication such as WiFi (registered trademark). There is a technique for transmitting to a positioned image generation device. In this technique, the image generation device generates an image based on the received detection data, and displays the image on, for example, a display adjacent to the image generation device. The operator visually confirms the image displayed on the display to confirm whether the image is a desired image. If the displayed image is a desired image, the image is stored in a storage device such as a hard disk provided in the image generation device via an operation means such as a touch panel provided in the display.

  In the above technique, when wireless communication becomes unstable during transmission / reception of detection data, the detection data may not be transmitted / received. In this case, the operator requests the FPD to retransmit the detection data via the operation means. Upon receiving the request, the FPD transmits again the detection data stored in the buffer to the image generation apparatus.

JP 2008-134057 A

  However, in the above technique, when detection data related to past shooting as well as detection data related to the latest shooting is stored in the buffer in the FPD, the FPD erroneously detects the detection data related to the previous shooting. May be sent to. More specifically, for example, when two consecutive shootings are performed, the detection data related to the first shooting that is the past shooting is not used instead of the detection data related to the second shooting that is the latest shooting. It is conceivable that the FPD transmits to the image generation apparatus. In such a case, the determination that the detection data received by the image generation device is the detection data related to the latest photographing is dependent only on the operator.

  The problem to be solved by the present invention is to provide a medical diagnostic apparatus that can reduce the possibility of data misunderstanding when data related to imaging by the medical diagnostic apparatus is transmitted and received by wireless communication.

  In order to solve the above problems, a medical diagnostic apparatus according to an embodiment is based on an imaging unit that wirelessly transmits data acquired by imaging, a receiving unit that receives the data, and the data received by the receiving unit. An image generation unit for generating an image, an image storage unit capable of storing the image generated by the image generation unit, an image newly generated by the image generation unit, and an image stored in the image storage unit An image comparison unit for comparison, and a display unit for displaying a comparison result by the image comparison unit.

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

  The medical diagnostic apparatus in the present embodiment is, for example, a general X-ray imaging apparatus. Hereinafter, the configuration of a general X-ray imaging apparatus will be briefly described. FIG. 1 is a perspective view of an imaging unit 1 of a general X-ray imaging apparatus according to this embodiment. The imaging unit 1 of the general X-ray imaging apparatus in the present embodiment includes an X-ray irradiation unit 2, a base unit 3, a telescopic unit 4, a first rail 5, a second rail 6, an imaging table 7, an FPD 8, and an operation panel. 9 is provided.

  The first rail 5 supports the second rail 6 so as to be movable in the direction of arrow a. The second rail 6 supports the base portion 3 so as to be movable in the direction of the arrow b. The base part 3 supports the telescopic part 4 so that it can rotate in the direction of arrow C. The expansion / contraction part 4 supports the X-ray irradiation part 2 so that it can move up and down in the direction of arrow d, and supports the X-ray irradiation part 2 so that it can rotate in the directions of arrow e and arrow f. The movement and rotation of the second rail 6, the base part 3, the telescopic part 4, and the X-ray irradiation part 2 are manually performed by an operator, for example.

  As shown in FIG. 1, the imaging table 7 can insert the FPD 8 from the outside, and supports the FPD so as to be movable in the direction of the arrow g.

  FIG. 2 is a side view of the photographing unit 1 in the present embodiment. X-rays irradiated from the X-ray irradiation unit 2 pass through the patient P and are detected by the FPD 8. Note that a range surrounded by a dotted line (irradiation range 101) in FIG. 2 is a range in which X-rays are irradiated, and the irradiation range 101 changes depending on an X-ray diaphragm described later. In addition, the FPD 8 is usually positioned directly below the X-ray irradiation unit 2 so that the X-rays irradiated by the X-ray irradiation unit 2 and transmitted through the patient P are detected by the FPD 8.

  FIG. 3 is a block diagram of a general X-ray imaging apparatus according to this embodiment. The general X-ray imaging apparatus according to the present embodiment includes a console 10 in addition to the imaging unit 1 illustrated in FIG. 1. The console 10 includes an image processing unit 11, a display unit 12, an operation unit 13, an image comparison unit 14, A dialog generation unit 15 is provided. Note that the imaging unit 1 is installed in a dedicated imaging room so that X-rays do not leak outside during imaging, and the console 10 is installed outside the imaging room so that an operator is not exposed during imaging.

  The X-ray irradiation unit 2 includes an X-ray control unit (not shown), an X-ray tube (not shown), and an X-ray diaphragm (not shown). The X-ray control unit controls the output of X-rays generated by the X-ray tube. The X-ray diaphragm adjusts an irradiation range 101 of X-rays generated by the X-ray tube. The operation panel 9 in FIG. 1 is, for example, a touch panel, and the operator operates a predetermined operation screen displayed on the operation panel 9 to adjust the X-ray output setting and the irradiation range 101. X-ray irradiation is performed by pressing a switch installed on the operation unit 13 in the image processing unit 10 to be described later.

  The FPD 8 includes a buffer 31, an X-ray detection unit 32, a detection data transmission unit 33, and a retransmission instruction reception unit 34. The X-ray detection unit 32 detects X-rays emitted from the X-ray irradiation unit and transmitted through the patient. The detected X-ray is converted into a digital signal, and is temporarily stored in the buffer 31 installed in the FPD 8 as detection data. The detection data transmission unit 33 automatically transmits the detection data temporarily stored in the buffer 31 to the image processing unit 11 using wireless communication such as WiFi (registered trademark). Further, the detection data transmission unit 33 is temporarily stored in the buffer 31 when the retransmission instruction reception unit 34 receives an instruction to retransmit the detection data from a retransmission instruction transmission unit 38 of the image processing unit 11 described later. The detected data is transmitted to the image processing unit 11 using wireless communication such as WiFi (registered trademark).

  The image processing unit 11 includes a detection data reception unit 35, an image generation unit 36, an image storage unit 37, and a retransmission instruction transmission unit 38. The detection data receiving unit 35 receives the detection data transmitted from the FPD 8. The image generation unit 36 generates an image based on the detection data received by the detection data reception unit 35. The newly generated image is automatically displayed on the display unit 12. The image storage unit 37 stores a newly generated image in accordance with an operator instruction via the operation unit 13. If the detection data receiving unit 35 has not received the detection data even after a predetermined time has elapsed after the X-ray irradiation has ended, the image processing unit 11 sends the detection data to the dialog generation unit 15 described later. Is instructed to generate a dialog (re-acquisition dialog) for notifying the operator of the re-acquisition. When a reacquisition dialog generated by a dialog generation unit 15 to be described later is displayed on the display unit 12, the retransmission instruction transmission unit 38 transmits a detection data retransmission instruction to the FPD 8. The predetermined time described above is set, for example, when the operator inputs a numerical value on a predetermined operation screen displayed on the display unit 12 via the operation unit 13.

  The image comparison unit 14 compares all the images stored in the image storage unit 37 with the newly generated image by, for example, binary check. When the newly generated image matches any of the images stored in the image storage unit 37, the image comparison unit 14 generates a dialog (warning dialog) for notifying the operator of the comparison result by the image comparison unit 14. The dialog generation unit 15 is instructed to do so.

  The dialog generation unit 15 generates a reacquisition dialog according to an instruction from the image processing unit 11 and causes the display unit 12 to display the generated reacquisition dialog. Further, a warning dialog is generated according to an instruction from the image comparison unit 14 and the generated warning dialog is displayed on the display unit 12.

  The display unit 12 displays a re-acquisition dialog and a warning dialog in addition to the newly generated image. The display unit 12 displays options (“save button” and “failure button”) as to whether or not to store the newly generated image in the image storage unit 37 and a predetermined operation screen. The display unit 12 displays an image stored in the image storage unit 37 in accordance with an operator instruction via the operation unit 13.

FIG. 4 is a schematic diagram of a reacquisition dialog displayed on the display unit 12. The reacquisition dialog has a message field 23. In the message column, as shown in FIG. 4, a message indicating that the detection data could not be acquired and a message indicating that re-acquisition is to be performed are displayed.

  FIG. 5 is a schematic diagram of a warning dialog displayed on the display unit 12. The warning dialog has a message field 24. In the message column 24, a message is displayed indicating that a newly generated image matches one of the images stored in the image storage unit 37 as a result of comparison by the image comparison unit 14 described later.

  When the operator selects the above-described “save button” via the operation unit 13, the image processing unit 11 stores the newly generated image as it is in the image storage unit 37. On the other hand, when the operator selects the above-mentioned “failure button” via the operation unit 13, a memo field for writing the reason for the failure is displayed on the display unit 12 as a predetermined operation screen. The operator inputs the reason for the copy failure into the memo field via the operation unit 13. When the input of the reason for the copying failure is completed, the newly generated image is stored in the image storage unit 37 as the data for handling the copying failure together with the memo input by the operator in the memo field.

  As described above, the display of the warning dialog means that the newly generated image matches one of the images stored in the image storage unit 37, so that the operator can select the newly generated image. Can be determined to have been generated based on detection data relating to past imaging that the FPD 8 transmitted in error. On the other hand, the fact that the warning dialog is not displayed means that the newly generated image does not match all the images stored in the image storage unit 37, so that the operator can confirm that the newly generated image is the latest. It can be determined that the data is generated based on the detection data related to the shooting. With the above in mind, the operator makes a visual check and then determines whether to save the newly generated image or treat it as a damaged image.

  The operation unit 13 is, for example, a mouse, a keyboard, or a touch panel. The operator selects the save / failure button or inputs to a predetermined operation screen via the operation unit 13. On the other hand, the operation unit 13 has a switch for instructing X-ray irradiation as described above, and X-ray irradiation is performed when the operator presses this switch.

  FIG. 6 is a flowchart in the present embodiment. Note that the flow shown in FIG. 6 is a flow when transmission / reception of detection data between the FPD 8 and the image processing unit 11 fails.

  In step S1, an image generation / storing process for one shooting is started. The operator depresses the switch of the operation unit 13 and performs X-ray irradiation by the X-ray irradiation unit 2. The irradiated X-rays pass through the patient and are detected by the X-ray detection unit 32 of the FPD 8. The detected X-ray is converted into a digital signal and temporarily stored in the buffer 31 in the FPD 8 as detection data. The stored detection data is automatically transmitted to the detection data receiving unit 35 of the image processing unit 11 by the detection data transmitting unit 33.

  In step 2, since the detection data is not received by the detection data receiving unit 35, the image processing unit 11 instructs the dialog generation unit 15 to generate a reacquisition dialog. The dialog generation unit 15 generates a reacquisition dialog and causes the display unit 12 to display the generated reacquisition dialog. When the reacquisition dialog is displayed on the display unit 12, the retransmission instruction transmission unit 38 of the image processing unit 11 instructs the retransmission instruction reception unit 34 of the FPD 8 to retransmit the detection data.

  In step S3, when the detection data reception unit 35 of the image processing unit 11 has successfully received the detection data retransmitted by the detection data transmission unit 33 of the FPD 8, the process proceeds to step S4. On the other hand, when the detection data reception unit 35 of the image processing unit 11 fails to receive the detection data retransmitted by the detection data transmission unit 33 of the FPD 8 in S3, the process proceeds to step S2.

  In step S4, the image generation unit 36 of the image processing unit 11 generates an image based on the received detection data. The generated image is automatically displayed on the display unit 12.

  In step S5, the image comparison unit 14 compares all the images stored in the image storage unit 37 of the image processing unit 11 with the newly generated image displayed on the display unit 12 by binary check or the like. .

  In step S <b> 6, if the newly generated image matches any of the images stored in the image storage unit 37 in the comparison result by the image comparison unit 14, the image processing unit 11 generates a warning dialog in the dialog generation unit 15. Is transferred to step S7. On the other hand, if the newly generated image does not match all the images stored in the image storage unit 37, the process proceeds to step S8.

  In step S <b> 7, the dialog generation unit 15 causes the display unit 12 to display a warning dialog generated according to an instruction from the image processing unit 11. Thereafter, the process proceeds to step S8.

  In step S <b> 8, the operator selects the “save button” or “failure button” displayed on the display unit 12 via the operation unit 13. When the operator selects the “save button”, the process proceeds to step S9. On the other hand, when the operator selects the “failure button”, a memo field for writing the reason for the failure is displayed on the display unit 12 as a predetermined operation screen. The operator inputs the reason for the image loss in the memo field via the operation unit 13. When the operator inputs the reason for the failure, the newly generated image is stored in the image storage unit 37 as the failure handling data together with the memo entered by the operator in the memo field, and the process proceeds to step S2.

  In step S <b> 9, the image processing unit 11 stores the newly generated image as it is in the image storage unit 37.

  In step S10, the image generation / storing process for one shooting is completed.

  With the above configuration, the general X-ray imaging apparatus according to the present embodiment compares an image based on newly acquired detection data using wireless communication with an image related to past imaging, and is the same as an image related to past imaging. You can select and save images that are not. That is, even when the image processing apparatus 11 has erroneously acquired detection data relating to past shooting temporarily stored in the buffer 31 in the FPD 8, a warning dialog based on the comparison by the image comparison unit 14 is displayed. Since the image is displayed on the display unit 12, it is no longer necessary to rely solely on the operator to determine that the newly generated image is not an image related to past shooting as in the related art. As a result, the possibility of mistaken images to be stored is reduced.

  In step S6, if the newly generated image matches any of the images stored in the image storage unit 37 in the comparison result by the image comparison unit 14, the image processing unit 11 informs the dialog generation unit 15 of a warning dialog. In addition to instructing the generation of the image, the image stored in the matched image storage unit 37 may be displayed on the display unit 12 together with the newly generated image. As a result, not only a mechanical judgment but also an operator's visual judgment is possible, so that the possibility that the image is mistakenly stored is further reduced.

  The present embodiment can be applied even when the image processing unit 11 is included in the photographing unit 1. In that case, the data transmitted from the photographing unit 1 to the console 10 is not detection data but image data.

  Further, the imaging unit 1 may transmit detection data including incidental information such as the date and time of imaging and the output of X-rays at the time of imaging to the console 10. In that case, not only the image but also the accompanying information is compared. This allows for a more rigorous comparison and further reduces the possibility of mistaking and storing images.

  Furthermore, when the newly generated image does not match all of the images stored in the image storage unit 37, the dialog generation unit 15 in the present embodiment does not generate a dialog, but the newly generated image May be generated and displayed on the display unit 12 with a message indicating that it does not match all of the images stored in the image storage unit 37. In this case, it is expected that the familiarity of the comparison result to the operator will increase.

  In the present embodiment, the specification has been described in which the detection data is re-acquired automatically. However, naturally, the detection data may be re-acquired in accordance with an instruction from the operator. In this case, for example, the re-acquisition dialog is provided with a not-shown YES button and a not-shown NO button in addition to the message field 23, and when the operator selects the YES button via the operation unit 13, re-send The instruction transmission unit 38 transmits an instruction to retransmit the detection data to the retransmission instruction reception unit 34. Conversely, when the operator selects the NO button, the retransmission instruction transmission 38 does not transmit a detection data retransmission instruction to the retransmission instruction reception unit 34.

  In this embodiment, in addition to a general X-ray imaging apparatus, image data or image base using wireless communication, such as a mammography apparatus using a wireless FPD or an ultrasonic diagnostic apparatus using a wireless ultrasonic probe. Any medical diagnostic apparatus that communicates data to be used can be sufficiently applied. For example, when applied to an ultrasonic diagnostic apparatus, echo signal data based on a reflected wave received by the ultrasonic probe is temporarily stored in a memory in the ultrasonic probe. The ultrasonic probe transmits the echo signal data temporarily stored in the memory to the image processing apparatus in the ultrasonic diagnostic apparatus by wireless communication. The image processing device generates an ultrasonic image based on the received echo signal, and compares the image generated by the image comparison device in the ultrasonic diagnostic device with the ultrasonic image obtained in the past diagnosis. Only the ultrasonic diagnostic image related to the latest diagnosis can be acquired.

  As mentioned above, although embodiment of this invention was described, these embodiment is shown as an example and is not intending limiting the range of invention. These novel embodiments can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the spirit of the invention. These embodiments and modifications thereof are included in the scope and gist of the invention, and are included in the invention described in the claims and the equivalents thereof.
