Description

  The present invention relates to a technique for improving security of a medical image diagnostic apparatus, and more particularly to a medical image diagnostic apparatus that authenticates an operator without impairing operability.

  Since medical data such as subject information and image information includes personal information, high security is required. In recent years, the US federal law HIPAA (Health Insurance Portability and Accountability Act), which defines data and privacy on subjects, has been institutionalized and legislated in the United States to manage users within hospitals. And the need for access management is growing rapidly.

  A medical image diagnostic apparatus such as an ultrasonic diagnostic apparatus is also required to support the above-mentioned HIPAA, and there are a number of authentication techniques related to the security of the medical diagnostic apparatus (for example, Patent Document 1).

  In conventional medical image diagnostic apparatuses, authentication is performed by inputting a user ID (or name) and password into the apparatus, and biometrics (biological characteristics) such as fingerprints, eyes, faces, voices, handprints, handwriting, etc. There is known one that performs authentication using.

JP 2001-344349 A

  However, the authentication method for inputting the user ID and password requires the inspector to input the user ID and password each time the inspector (operator) changes. In particular, in the inspection by the ultrasonic diagnostic apparatus, since the inspector frequently changes, the number of input operations increases, and the work that is very complicated for the inspector increases.

  In the authentication method using biometrics (biological features), first, settings for preparation for authentication are performed, and then authentication is performed. For example, when fingerprint authentication is performed using a fingerprint sensor, the medical image diagnostic apparatus performs an operation for starting the fingerprint authentication operation, and then the examiner performs fingerprint authentication by placing a finger on the fingerprint sensor. ing. This authentication method using biometrics is superior in operability compared with a method of inputting a user ID or the like because it is not necessary to input a user ID or the like. However, since it is necessary to perform a setting operation for preparation for authentication for each examination, the troublesome work for the inspector increases as in the method of inputting the user ID and the like.

  Further, in a medical image diagnostic apparatus such as an ultrasonic diagnostic apparatus, the subject information for specifying the subject in the apparatus is reset every time the subject is changed, and then the subject is imaged to obtain image data. ing. A reset switch for giving an instruction for resetting the subject information to the apparatus is installed in the medical image diagnostic apparatus, and the examiner resets the subject information by pressing the reset switch. As described above, it is necessary to press the reset switch every time the subject changes, but in order to increase the security of medical data, in addition to pressing the reset switch, the above-described operation for ensuring security is required.

  As described above, in the conventional medical image diagnostic apparatus, it is necessary to press the reset switch when performing an inspection, and the inspector needs to perform some setting or input work in order to perform authentication. It was a burden for the person. In other words, if an authentication technique for increasing the security of medical data is introduced into the medical image diagnostic apparatus, the medical data security is increased, but the operability of the medical image diagnostic apparatus is impaired, and the burden on the examiner increases. .

  SUMMARY OF THE INVENTION An object of the present invention is to provide a medical image diagnostic apparatus capable of ensuring the security of medical data without impairing the operability of the medical image diagnostic apparatus.

  The transmission / reception unit 3 includes a transmission unit that drives the ultrasonic probe 2 and a reception unit that receives a signal from the ultrasonic probe 2. The transmission unit generates a clock signal that determines the transmission timing and transmission frequency of the ultrasonic signal, and performs transmission focusing with a delay when transmitting the ultrasonic wave. Further, a drive pulse is generated at a transmission timing multiplied by a delay and supplied to each transducer of the ultrasonic probe 2. The receiving unit amplifies the echo signal output from each transducer of the ultrasonic probe 2 for each reception channel, and performs A / D conversion on the amplified echo signal. A delay time necessary for determining the reception directivity is given to the echo signal after the A / D conversion and added. By the addition, the reflection component from the direction according to the reception directivity is emphasized.

  The signal processing unit 4 performs band pass filter processing on the signal output from the transmission / reception unit 3. Thereafter, the envelope is detected, and the detected data is subjected to compression processing by logarithmic transformation to generate a B-mode image signal.

  The image generation unit 5 converts the B-mode image signal after the signal processing represented by the scanning line signal sequence output from the signal processing unit 4 into coordinate system data based on the spatial information (scan conversion processing). That is, the scanning method is converted by reading out in synchronization with the standard television scanning so that the signal sequence synchronized with the ultrasonic scanning can be displayed on the display unit 6 of the television scanning method. Thereafter, D / A conversion processing is performed, and a luminance signal (tomographic image data) converted into an analog format is output to the display unit 6. The display unit 6 is a monitor that displays the luminance signal output from the image generation unit 5 as a tomographic image.

  The operation unit 7 includes an operation panel 72, a TCS (Touch Command Screen) 73, and the like, and further includes a switch 71 in which a reset switch 71a and a fingerprint sensor 71b are combined.

  The reset switch 71a is a switch that is pressed when resetting the subject information input to the ultrasound diagnostic apparatus 1 and imaging information indicating imaging conditions, and is pressed every time the subject changes. . In other words, this switch is pressed first before the ultrasonic diagnostic apparatus 1 examines a new subject. The reset switch 71a is generally referred to as “New Patin Switch”. The fingerprint sensor 71b is a sensor that detects a fingerprint of a finger when the finger is placed on the fingerprint sensor 71b. A switch 71 is formed by combining the reset switch 71a and the fingerprint sensor 71b.

  The appearance of the operation unit 7 will be described with reference to FIG. FIG. 2 is a top view showing the external appearance of the operation panel and TCS provided in the ultrasonic diagnostic apparatus according to the first embodiment of the present invention. The operation panel 72 mainly includes a freeze button 72a, a trackball 72b, and a plurality of operation buttons 72c, and a TCS 73.

  The freeze button 72a is used when obtaining a still image of the ultrasonic image being displayed on the screen of the display device. When the examiner presses the freeze button 72a, the still image is displayed on the screen of the display device. Can do. The trackball 72b is used when setting a region of interest such as a measurement cursor.

For example, an operation button relating to image quality adjustment of an image is displayed, an operation button relating to a diagnostic application such as distance or area measurement is displayed, or an operation button relating to a body mark serving as supplementary information of an image is displayed.

  A switch 71 in which a reset switch 71 a and a fingerprint sensor 71 b are incorporated is installed on the operation panel 72. In FIG. 2, the switch 71 is installed beside the TCS 73, but the installation location is not limited to this location and may be installed around the trackball 72b or the like.

  A detailed configuration of the switch 71 including the reset switch 71a and the fingerprint sensor 71b will be described with reference to FIG. FIG. 3A is a top view of the switch 71 including the reset switch 71a and the fingerprint sensor 71b. FIG. 3B is a cross-sectional view of the switch 71 taken along the line segment A-A ′ in FIG.

  As shown in FIGS. 3A and 3B, the switch 71 is formed by incorporating a fingerprint sensor 71b into a reset switch 71a having a circular shape, for example. The switch 71 protrudes from the surface of the operation panel 72 and is provided on the operation panel 72. When pressed, the switch 71 is pushed in the direction inside the operation panel 72 (direction of arrow A). The fingerprint sensor 71b is installed on the surface side of the reset switch 71a, and when the inspector puts a finger on the reset switch 71a, the fingerprint of the finger is detected.

  When the switch 71 is pressed by the examiner, the switch 71 is pressed in the direction inside the operation panel 72 (in the direction of arrow A), and a signal corresponding to the pressing is sent via the control unit 13 to the subject information reset unit 10. And output to the imaging information reset unit 14. Furthermore, since the fingerprint sensor 71b is installed on the front side of the reset switch 71a, when the finger is placed on the switch 71 and the switch 71 is pressed, the fingerprint of the finger is detected by the fingerprint sensor 71b, and the detected fingerprint information Is output to the verification unit 8 via the control unit 13.

  In this way, by providing the switch 71 combining the reset switch 7a and the fingerprint sensor 7b, the inspector simply presses down the combined switch 71 and follows the fingerprint authentication and prior to the inspection by the ultrasonic diagnostic apparatus 1. It is possible to reset the subject information and the imaging information performed in this manner.

  The collation unit 8 collates the fingerprint information of the inspector detected by the fingerprint sensor 71b with the fingerprint information (identification information) stored in the fingerprint data memory 9 registered in advance, thereby matching / mismatching the fingerprints Make a decision. The fingerprint data memory 9 stores fingerprint information (identification information) of an inspector who is permitted to operate the ultrasonic diagnostic apparatus 1. The examiner who has been given the operation permission can image the subject with the ultrasonic diagnostic apparatus 1 and can access and read out image data, subject information, and the like recorded in the ultrasonic diagnostic apparatus 1. Become. The collation unit 8 performs fingerprint collation by reading fingerprint information (identification information) from the fingerprint data memory. The verification unit 8 corresponds to “authentication means” of the present invention.

  The subject information memory 11 stores subject information for specifying a subject to be examined by the ultrasonic diagnostic apparatus 1. For example, the subject information includes a subject ID and a name given to each subject. The examiner inputs subject information including a subject ID or the like from the operation unit 7 when performing an examination, and the subject information is stored in the subject information memory 11. In addition, when the ultrasonic diagnostic apparatus 1 is connected to a server in which subject information is stored via a network, the subject information is transmitted from the server when the examination is performed, and the subject information memory 11 Stored in This subject information memory 11 corresponds to the “subject information storage means” of the present invention.

  The subject information reset unit 10 resets the subject information stored in the subject information memory 11 and enables reception of new subject information. When the reset switch 71a is pressed by the examiner, a signal corresponding to the pressing is received, and the subject information reset unit 10 prohibits the use of the subject information stored in the subject information memory 11, and newly The subject information of the correct subject is received. Since the reset switch 71a is pressed every time the subject changes, the subject information reset unit 10 resets the subject information in the subject information memory 11 every time the subject changes. The subject information reset unit 10 corresponds to the “reset means” of the present invention.

  After the subject information is reset, the subject information of a new subject is input via the operation unit 7 or the network and stored in the subject information memory 11. Thereafter, the new subject is examined. The ultrasound image obtained by the ultrasound diagnostic apparatus 1 is recorded in the recording unit 12 in association with the subject information stored in the subject information memory 11. If the subject information is not reset, an ultrasonic image of a different subject is recorded in association with certain subject information, leading to misdiagnosis. In order to prevent this, the subject information is reset each time a new subject is examined, and new subject information is received.

  The imaging information memory 15 stores imaging information indicating conditions for imaging by the ultrasonic diagnostic apparatus 1. This imaging information includes, for example, imaging conditions such as ultrasonic scanning line density, the number of samples, the number of parallel simultaneous receptions, a pulse repetition frequency (PRF), and a frame rate. The inspector inputs imaging information from the operation unit 7 when performing an examination, and the imaging information is stored in the imaging information memory 15, and the ultrasound diagnostic apparatus 1 stores the imaging information via a network. When the inspection is performed, the imaging information is transmitted from the server and stored in the imaging information memory 15. Further, the imaging information stored in the imaging information memory 15 is sequentially updated according to the input from the outside. The imaging information memory 15 corresponds to “imaging information storage means” of the present invention.

  The imaging information reset unit 14 resets imaging information stored in the imaging information memory 15 and enables reception of new imaging information. When the inspector presses the reset switch 71a, the imaging information reset unit 14 receives the signal corresponding to the pressing, and the imaging information stored in the imaging information memory 15 is set to the initial imaging conditions set in advance. Is returned to the initial imaging information indicating that the imaging information indicating new imaging conditions is received. Accordingly, when the imaging information is reset, the imaging information stored in the imaging information memory 15 is updated to the initial imaging information indicating the initial conditions for imaging, and the initial imaging information is stored. The preset initial imaging information means, for example, imaging conditions set at the time of factory shipment, imaging conditions in which each setting value is a default value, and the like. Since the reset switch 71a is pressed every time the subject changes, the imaging information reset unit 14 resets the imaging information in the imaging information memory 15 every time the subject changes. The imaging information reset unit 14 corresponds to the “reset means” of the present invention.

  After the imaging information is reset, the imaging information stored in the imaging information memory 15 is reset to preset initial imaging information, and then new imaging information is input via the operation unit 7 or the network. And stored in the imaging information memory 15. Thereafter, the inspection is performed under the imaging condition indicated by the new imaging information.

  Further, the ultrasonic diagnostic apparatus 1 is provided with a recording unit 12 and a control unit 13. The recording unit 12 includes a memory, a hard disk, and the like, and records data such as tomographic images generated by the signal processing unit 4 and the image generation unit 5, various setting conditions of the ultrasonic diagnostic apparatus 1, programs, and the like. For example, the ultrasound image obtained by the ultrasound diagnostic apparatus 1 and the subject information are recorded in association with each other, the imaging information and the subject information are recorded in association with each other, or the ultrasound image and the imaging information are recorded. And the subject information are recorded in association with each other.

  Furthermore, an operation history when the examiner operates the ultrasonic diagnostic apparatus 1 is recorded in the recording unit 12. In the operation history, the function actually performed by the inspector is written, and further, the user name of the inspector, the diagnostic content, the ultrasonic mode, and the like are written together with the date and time when the operation is performed. As an example of the operation history, the identification information (fingerprint information, user name, user ID, etc.) of the inspector is obtained from the imaging information indicating the imaging conditions performed by the inspector (from the inspector's authentication to the next authentication) Imaging conditions), object information, ultrasonic images, and the like. The control unit 13 is connected to each unit of the ultrasonic diagnostic apparatus 1 and controls each unit. The recording unit 12 corresponds to the “recording unit” of the present invention.

(Operation)
Next, the operation of the ultrasonic diagnostic apparatus as the medical image diagnostic apparatus according to the embodiment of the present invention will be described with reference to FIG. FIG. 4 is a flowchart showing the operations of the ultrasonic diagnostic apparatus according to the embodiment of the present invention in order.

  In order to reset the subject information of the subject that has been examined earlier, which is stored in the subject information memory 11 when examining a new subject, the examiner places a finger on the switch 71 and switches the subject information. 71 is pressed (step S01). A signal corresponding to this depression is output to the control unit 13 and temporarily stored. In this state, since the examiner is not authenticated, the subject information resetting unit 10 does not reset the subject information stored in the subject information memory 11. Similarly, the imaging information reset unit 14 does not reset the imaging information stored in the imaging information memory 15.

  In step S01, when the inspector places his finger on the switch 71 and presses the switch 71, the fingerprint of the inspector's finger is detected by the fingerprint sensor 71b provided on the surface side of the switch 71 (step S02). ). Fingerprint information detected by the fingerprint sensor 71 b is output to the collation unit 8 via the control unit 13.

  When the collation unit 8 receives the fingerprint information from the fingerprint sensor 71b, the collation unit 8 reads the fingerprint information (identification information) registered in advance from the fingerprint data memory 9. Then, the fingerprint information read by the fingerprint sensor 71b and the fingerprint information (identification information) stored in the fingerprint data memory 9 are compared and collated to determine whether they match (step). S03). Since the fingerprint information (identification information) stored in the fingerprint data memory 9 is the fingerprint information (identification information) of the inspector who is permitted to log in to the ultrasonic diagnostic apparatus 1, the fingerprint read by the fingerprint sensor 71b. If the information matches the fingerprint information (identification information) stored in the fingerprint data memory 9, it is determined that the inspector having the fingerprint is an inspector who can log in.

  If the collation unit 8 determines that the fingerprint information read by the fingerprint sensor 71b matches the fingerprint information (identification information) stored in the fingerprint data memory 9 (Yes in step S04), the fingerprint is The inspector possessed is authenticated and allowed to log in to the ultrasonic diagnostic apparatus 1 (step S05). Specifically, this authentication enables the use of the ultrasonic diagnostic apparatus 1, and imaging and reference of medical data (for example, image data) stored in the recording unit 12 of the ultrasonic diagnostic apparatus 1 can be performed.

  The collation result is output from the collation unit 8 to the control unit 13. If the result of the collation is a determination result that the fingerprint information matches, the control unit 13 confirms that the reset switch 71a is already pressed, and the control unit 13 checks the subject information reset unit 10 with the subject. A command is sent to reset the subject information stored in the information memory 11. The subject information reset unit 10 resets the subject information stored in the subject information memory 11 in accordance with a reset command from the control unit 13 (step S07). Thereby, the use of the subject information before authentication is prohibited, and the subject information of a new subject is accepted. Then, subject information newly input via the operation unit 7 or the network is stored in the subject information memory 11.

  Further, when it is determined that the fingerprint information matches, the control unit 13 sends a command to the imaging information reset unit 14 to reset the imaging information stored in the imaging information memory 15. The imaging information reset unit 14 resets the imaging information stored in the imaging information memory 15 according to a reset command from the control unit 13. When the imaging information is reset in this way, the imaging information stored in the imaging information memory 15 is updated to initial imaging information indicating initial conditions for imaging, and the initial imaging information is stored in the imaging information memory 15. Will be. When new imaging information is input via the operation unit 7 or the network, the new imaging information is stored in the imaging information memory 15.

  After the subject information is reset, the subject information of the new subject is input to the ultrasound diagnostic apparatus 1 by the operation unit 7 or the like, and the subject information of the new subject is stored in the subject information memory 11. The Further, after the imaging information is reset and updated to the initial imaging information, imaging information indicating new imaging conditions is input to the ultrasound diagnostic apparatus 1 by the operation unit 7 or the like, and the new imaging information is stored in the imaging information memory. 15 is stored. Then, ultrasonic waves are transmitted / received to / from the new subject under new imaging conditions to obtain image data (for example, tomographic image) of the subject (step S07). This image data is recorded in the recording unit 12 in association with new subject information. Alternatively, the imaging information and the subject information are associated and recorded in the recording unit 12.

  If the collation unit 8 determines in step S04 that the fingerprint information detected by the fingerprint sensor 71b does not match the fingerprint information (identification information) stored in the fingerprint data memory 9 (step S04, No), the inspector with the fingerprint is not authenticated and is not permitted to log in to the ultrasonic diagnostic apparatus 1. That is, the ultrasonic diagnostic apparatus 1 cannot be used. As a result, it is impossible to perform imaging or referencing medical data (for example, image data) recorded in the recording unit 12 of the ultrasonic diagnostic apparatus 1.

  The collation result is output from the collation unit 8 to the control unit 13. If the result of the collation is a determination result that the fingerprint information does not match, the control unit 13 does not send a reset command to the subject information reset unit 10 and the imaging information reset unit 14, and as a result, the subject information reset The unit 10 does not reset the subject information stored in the subject information memory 11, and the imaging information reset unit 14 does not reset the imaging information stored in the imaging information memory 15.

  Further, the control unit 13 that has received the determination result that the fingerprint information does not match requests the inspector to input a user ID and a password, and outputs a request display command to the display unit 6. In response to the display command, the display unit 6 displays "Please enter user ID and password" (step S08).

  The inspector inputs a user ID and a password (hereinafter referred to as a user ID or the like) using a keyboard or the like installed on the operation unit 7 in accordance with the request displayed on the display unit 6 (step S09). Upon receiving this user ID and the like, the collation unit 8 reads the user ID and password (both are identification information) registered in advance in the ultrasonic diagnostic apparatus 1 and determines whether or not the user ID and the like match. Do.

  If the collation unit 8 determines that the user ID and the like match (step S10, Yes), the inspector having the user ID and the like is authenticated and login of the ultrasonic diagnostic apparatus 1 is permitted (step S10). S11). That is, the ultrasonic diagnostic apparatus 1 can be used by this authentication.

  The collation result is output from the collation unit 8 to the control unit 13. When the result of the collation is a determination result that the user IDs and the like match, the control unit 13 resets the subject information stored in the subject information memory 11 with respect to the subject information reset unit 10. Send an order to do. The subject information reset unit 10 resets the subject information stored in the subject information memory 11 in accordance with a reset command from the control unit 13 (step S12). Thereby, the use of the subject information before authentication is prohibited, and the subject information of a new subject is accepted. Then, the subject information newly input via the operation unit 7 or the network is stored in the subject information memory 11.

  Furthermore, when it is determined that the user IDs match, the control unit 13 sends a command to the imaging information reset unit 14 to reset the imaging information stored in the imaging information memory 15. The imaging information reset unit 14 resets the imaging information stored in the imaging information memory 15 according to a reset command from the control unit 13. When the imaging information is reset in this way, the imaging information stored in the imaging information memory 15 is updated to initial imaging information indicating initial conditions for imaging, and the initial imaging information is stored in the imaging information memory 15. Will be. When new imaging information is input via the operation unit 7 or the network, the new imaging information is stored in the imaging information memory 15.

  After the subject information is reset, the subject information of the new subject is input to the ultrasound diagnostic apparatus 1 by the operation unit 7 or the like, and the subject information of the new subject is stored in the subject information memory 11. The Further, after the imaging information is reset and updated to the initial imaging information, imaging information indicating new imaging conditions is input to the ultrasound diagnostic apparatus 1 by the operation unit 7 or the like, and the new imaging information is stored in the imaging information memory. 15 is stored. Then, ultrasonic waves are transmitted / received to / from the new subject to obtain image data of the subject. This image data is recorded in the recording unit 12 in association with the subject information of the new subject. Alternatively, the imaging information and the subject information are associated and recorded in the recording unit 12.

  In step S10, when the collation unit 8 determines that the user ID or the like does not match (No in step S10), the inspector having the user ID or the like is not authenticated and is sent to the ultrasonic diagnostic apparatus 1. Login is denied. That is, the ultrasonic diagnostic apparatus 1 cannot be used.

  The collation result is output from the collation unit 8 to the control unit 13. When the result of the collation is a determination result that the user IDs do not match, the control unit 13 does not send a reset command to the subject information reset unit 10 and the imaging information reset unit 14, and as a result, the subject information The reset unit 10 does not reset the subject information stored in the subject information memory 11. Similarly, the imaging information reset unit 14 does not reset the imaging information stored in the imaging information memory 15.

  Furthermore, the control unit 13 outputs a login rejection display command to the display unit 6. In response to the display command, the display unit 6 displays “login refusal” or the like (step S13).

  As described above, by combining the reset switch 71a and the fingerprint sensor 71b that are first pressed when the ultrasonic diagnostic apparatus 1 examines a new subject, authentication of the examiner and subject can be performed by one operation. It is possible to reset the sample information. As a result, it is not necessary to place a finger on the fingerprint sensor 71b for authentication other than pressing the reset switch 71a. As described above, since it is not necessary to separately perform an operation for ensuring security in addition to resetting the subject information, it is possible to ensure the security of medical data without impairing the operability of the ultrasonic diagnostic apparatus 1. It becomes.

  Further, when access to the ultrasonic diagnostic apparatus 1 is permitted by authentication by fingerprint authentication or the like, the control unit 13 records the access history in the recording unit 12 as an operation history. In addition to access, the function actually performed by the inspector, the user name of the inspector, the diagnostic content, the ultrasonic mode, and the like are recorded in the recording unit 12 as the operation history together with the date and time when the operation was performed. The inspector who is authenticated and given access authority can view the operation history by operating the operation unit 7 of the ultrasonic diagnostic apparatus 1. For example, the identification information (fingerprint information, user name, user ID, etc.) of the examiner is associated with imaging information indicating the conditions of imaging performed by the examiner, subject information, ultrasonic images, and the like as an operation history. To be recorded.

  Since this operation history also includes the personal information of the subject, high security is required. The inspector who is given login permission by the above-described authentication can browse the operation history by the ultrasonic diagnostic apparatus 1.

  In the above-described embodiment, when the login is permitted in step S05, the medical data (image data or the like) stored in the recording unit 12 can be referred to, but is stored in the recording unit 12. Access authority restrictions may be imposed depending on the type of medical data. In other words, in addition to image data, information such as subject information, imaging information indicating imaging conditions, operation history, and the like are recorded in the recording unit 12, but the examiner places restrictions on access to each information. Also good.

  For example, a certain examiner is given access authority only to image data, and is not given access authority to information such as subject information and operation history. In order to perform such control, a table in which the identification information (fingerprint information, user name, user ID, etc.) of the inspector is associated with each information is created, and the collation unit 8 refers to the table, Grant permission to access each information.

  Specifically, the examiner A is given access authority to image data, the examiner B is given access authority to image data and subject information, and the examiner C is given image data and subject information. Access to the operation history is given, and a table representing the correspondence between the inspector's identification information (fingerprint information, user name, user ID, etc.) and each information is stored in the recording unit 12. When the verification unit 8 authenticates the inspector A and is granted access, the verification unit 8 further refers to the table recorded in the recording unit 12 to identify the inspector A. Information that can be accessed is searched from information (fingerprint information, user name, user ID, etc.) and its table. Since the inspector A is authorized to access only the image data, the collation unit 8 gives the inspector A only the access authority to the image data recorded in the recording unit 12.

  On the other hand, when the inspector B is authenticated by the verification unit 8 and access is granted, the verification unit 8 further verifies the verification unit 8 based on the table and the identification information (fingerprint information, etc.) of the inspector B. Searches for accessible information. Since the examiner B is given access authority to the image data and the subject information, the collation unit 8 gives the examiner B access authority to the image data and the subject information recorded in the recording unit 12. give. Similarly, for the inspector C, accessible information is searched based on the table and the identification information (fingerprint information, etc.) of the inspector C, and the inspector C is referred to the image data, the subject information, and the operation history. It becomes possible. In this way, it is possible to further improve the security of medical data by changing the level of access authority given by the examiner.

  Further, it may be determined whether to permit imaging based on the relationship between the examiner and the subject. For example, the examiner A is permitted to image the subject a, the examiner B is permitted to image the subject b, and the examiner C is permitted to image the subject c. Also good. More specifically, the operator who performs the imaging of the heart is permitted to perform imaging only for the subject undergoing the heart examination, and the examiner who performs the imaging of the abdomen is directed to the subject undergoing the examination of the abdomen. Only imaging permission may be given.

  In order to perform such control, when the collation unit 8 authenticates the inspector and gives the examiner permission of imaging, the collation unit 8 identifies the inspector's identification information (fingerprint information, user name, user ID, etc. ) And subject information. Based on the comparison, the collation unit 8 determines whether or not the pieces of identification information and part of the information included in the subject information match each other. Do not give permission to shoot.

  For example, in the case where information capable of imaging the heart is added to the identification information of the examiner A, and information for receiving a heart examination is added to the subject information of the subject to be imaged, the verification unit 8 gives the inspector A permission for photographing. On the other hand, when the subject information includes information for receiving an abdominal examination, the collation unit 8 does not give the examiner A permission for imaging. In this way, by giving imaging permission according to the relationship between the examiner and the subject, an operator who specializes in imaging of the heart is allowed only to take an image of the heart, and an examination that specializes in imaging of the abdomen Since the person is only allowed to take an image of the abdomen, it is no longer necessary to take an image of a non-specialized affected area, and the reliability of the ultrasonic image is improved.

  In this embodiment, the ultrasonic diagnostic apparatus is described as an example of the medical image diagnostic apparatus. However, a medical image diagnostic apparatus other than the ultrasonic diagnostic apparatus may be used. For example, a medical image diagnostic apparatus such as an X-ray CT apparatus, an X-ray diagnostic apparatus, or an MRI apparatus may be used. In each apparatus, a combination of a switch to be pressed first when performing an examination (corresponding to a reset switch 71a for resetting the subject information and imaging information in this embodiment) and the fingerprint sensor 71b is 1 By one operation, it is possible to execute a function that should function first with fingerprint authentication (corresponding to resetting object information and imaging information in this embodiment).

  In this embodiment, the switch 71 including the reset switch 71a and the fingerprint sensor 71b is provided, but only the fingerprint sensor 71b may be provided without providing the hardware reset switch 71a. When only the fingerprint sensor 71b is provided, the inspector places his / her finger on the fingerprint sensor 71b to read the inspector's fingerprint, and the collation unit 8 confirms the matching of the fingerprint to obtain authentication. The reset unit 10 receives the authentication and automatically resets the subject information stored in the subject information memory 11. Further, when the authentication is obtained, the imaging information reset unit 14 receives the authentication and automatically resets the imaging information stored in the imaging information memory 15. As described above, even if the hardware reset switch 71a for instructing the reset of the subject information and the imaging information is not provided, the authentication and the reset of the subject information and the imaging information are performed by one operation by software processing. Can be performed.

  That is, only the fingerprint sensor 71b that reads the fingerprint of the examiner for authentication is provided, and the reset of the subject information and the imaging information is processed by software. Since there is no need to separately perform an operation for resetting the imaging information, it is possible to restrict access without impairing the operability of the ultrasonic diagnostic apparatus 1, and to ensure the security of medical data such as image data and subject information. Is possible.

  In this embodiment, security is ensured by fingerprint authentication, but an authentication technique using biometrics (biological features) other than fingerprint authentication may be used. Biological features other than fingerprint authentication include handprints, eyes (retina, iris), voice (voiceprint), face, signature, and vein pattern on the back of the hand. An inspector may be authenticated using these biological characteristics.

  For example, when using voice (voice print) authentication, the voice is used as identification information of the inspector. When a microphone for inputting voice to the ultrasonic diagnostic apparatus 1 is provided, and the inputted voice (voice print) data is compared with previously registered voice (voice print) data (identification information), and they match. Is authenticated, the ultrasonic diagnostic apparatus 1 can be accessed, and then the subject information and the imaging information are automatically reset. As described above, for voice (voice print) authentication, as in fingerprint authentication, there is no need to perform a separate operation for resetting subject information and imaging information other than an operation for ensuring security. It becomes possible to ensure the security of medical data without impairing the operability of the device 1.

  In addition, the same effect can be obtained for an authentication technique that performs authentication by detecting the retina and iris. In this case, the retina or iris is used as the identification information of the examiner. When the ultrasonic diagnostic apparatus 1 is provided with a sensor for detecting a retina or an iris and is authenticated, the subject information and the imaging information are reset. As a result, it is not necessary to perform an operation for resetting the subject information and the imaging information other than an operation for ensuring security, so that it is possible to improve security without impairing operability. In addition, the same effect can be obtained by using a bill, a face, a signature, a vein pattern on the back of the hand, and the like as identification information, and an authentication technique using the identification information.

  Next, a medical diagnostic system including the medical image diagnostic apparatus according to this embodiment will be described with reference to FIG. FIG. 5 is a block diagram showing a schematic configuration of a medical diagnostic system provided with a medical image diagnostic apparatus.

  In hospitals, a hospital information system called HIS (Hospital Information System) is constructed between departments in the hospital in order to automate medical accounting work, prescription ordering work, and diagnosis support work. Within each department, for example, in the radiology department, an information system tailored to each department, such as RIS (Radiology Information System) and PACS (Picture Archiving Communication System), is being constructed, and online information transmission is being promoted. In such an information system, test results can be stored in HIS, RIS, and PACS servers, and information can be shared in hospitals.

  The medical diagnosis system 100 according to this embodiment is configured so that the HIS 110 that is an information system between departments in a hospital, the RIS 120 that is an information system in a radiation department, and the PACS 130 that is an image diagnosis system can communicate with each other. Connected and configured.

  The HIS 110 includes a server 111, a terminal device 113A of the department 112A, and a terminal device 113B of the department 112B. Examples of the department 112A and the department 112B include an accounting department, a medicine department, a medical examination department (such as an internal medicine department, a surgical department, and an orthopedic department). The server 111 stores subject information (subject ID, name, date of birth, etc.), accounting information, and prescription information.

  The RIS 120 includes a server 121, a terminal device 125 in the radiation department 124, a medical image diagnostic apparatus 123A in the examination room 122A, and a medical image diagnostic apparatus 123B in the examination room 122B. Each of the medical image diagnostic apparatus 123A and the medical image diagnostic apparatus 123B corresponds to a medical image diagnostic apparatus such as the ultrasonic diagnostic apparatus 1 according to the above-described embodiment. The server 121 includes a database of examination parameters for performing examinations by the medical image diagnostic apparatuses 123A and 123B and past executed information.

  The PACS 130 includes a server 131 and a terminal device 132. The server 131 stores image data acquired by the medical image diagnostic apparatuses 123A and 123B.

  An example of the flow of processing in such a medical diagnosis system 100 will be described. First, the subject goes to a department (for example, brain surgery, internal medicine, surgery, orthopedics, etc.) corresponding to the department 112A in the HIS 110 and a diagnosis department in the department 112B, and the subject information such as the chart and the subject ID number. Is submitted to the relevant diagnosis department (for example, department 112A).

  The doctor of the department 112A accesses the server 111 of the HIS 110 by using the ID number of the magnetic card submitted from the subject as a search key by the terminal device 113A, and from the personal data of the subject stored in the server 111, The personal data of the subject is read, and the subject is diagnosed while referring to the personal data. Then, the doctor writes an examination request such as ultrasonic imaging in the irradiation record, hands it to the subject, and instructs the radiation department 124 to go. The subject goes to the radiation department 124 with the magnetic card and the irradiation record given from the doctor, and gives the magnetic card and the irradiation record to the examiner.

  The inspector can acquire the subject information from the server 111 of the HIS 110 by inputting the subject information such as the subject ID and the examination number recorded on the magnetic card of the subject by the terminal device 125. After confirming the imaging request contents of the doctor described in the above, the imaging conditions and the like are determined.

  When the examiner finishes determining the necessary conditions, the examiner transmits the examination request information to the corresponding medical diagnostic apparatus (for example, the medical diagnostic apparatus 123A) in the medical diagnostic apparatuses 123A and 123B that actually perform imaging. Furthermore, the examination number is written on the magnetic card held by the subject.

  In the medical image diagnostic apparatus 123A, the examiner presses the switch 71. By pressing the switch 71, the fingerprint of the examiner's finger is detected by the fingerprint sensor 71b, and the fingerprint is collated (step S01 to step S03 shown in FIG. 4). If the fingerprint information matches the pre-registered fingerprint information (step S04, Yes), the login to the medical image diagnostic apparatus 123A is permitted (step S05), and the subject information and the imaging that have been input previously are captured. Information is reset (step S06).

  In addition, as described above, examination is performed using biological features other than fingerprint authentication, such as hand features, eyes (retina, iris), voice (voice print), face, signature, and vein pattern on the back of the hand. Authentication may be performed. Further, only the fingerprint sensor 71b may be provided without providing the hardware reset switch 71, and the subject information and the imaging information may be automatically reset after the authentication.

  When login to the medical diagnostic apparatus 123A is permitted in this way, the examiner reads the subject information of the magnetic card in which the subject information such as the subject ID number is recorded, and the subject included in the subject information is read. Based on the specimen ID and the examination number, the corresponding examination request information is selected from the examination request information list. The examiner confirms whether the content of the examination request matches the examination information described in the irradiation record owned by the subject, and starts imaging by the medical image diagnostic apparatus 123A after confirmation.

  When the imaging is completed, the execution information is transmitted from the medical image diagnostic apparatus 123A to the server 121 of the RIS 120. At the same time, the image data acquired by the medical image diagnostic apparatus 123A is transmitted from the medical image diagnostic apparatus 123A to the server 131 of the PACS 130.

  The transmission of the PACS 130 to the server 131 is often performed according to a medical image communication standard called DICOM. In DICOM, one file is formed simultaneously with an image using subject information, examination information, and imaging information as tags.

  The server 121 of the RIS 120 records examination execution information, the server 111 of the HIS 110 records accounting information, and the server 131 of the PACS 130 records image data. At this time, image data and subject information are recorded in association with each other. The doctor obtains image data from the server 131 of the PACS 130 and performs diagnosis in the terminal device of the HIS 110 or the terminal device of the PACS 130. The operation history of operating the medical image diagnostic apparatus 123A is recorded in the recording unit 12.

  As described above, the medical image diagnostic apparatuses 123A and 123B in the examination rooms 122A and 122B are connected to the server 111 of the HIS 110, the server 121 of the RIS 120, and the server 131 of the PACS 130 via the network. , 123B becomes accessible, the medical image diagnostic apparatuses 123A, 123B can acquire the subject information, examination information, and the like stored in each server.

  Accordingly, although the authentication of the examiner in the medical image diagnostic apparatuses 123A and 123B is important, according to the conventional authentication method, the operation for authentication and the reset of the subject information and the imaging information in the medical image diagnostic apparatus 123A are performed. Therefore, the operation is complicated and the operability is impaired. However, when the medical image diagnostic apparatus according to the above-described embodiment is used, it is possible to authenticate the examiner and reset the subject information and the imaging information by one operation. Is no longer necessary. Since there is no need to separately perform an operation for ensuring security, it is possible to ensure the security of medical data without impairing the operability of the medical image diagnostic apparatuses 123A and 123B.

  The collation unit 8, the subject information reset unit 10, the imaging information reset unit 14, and the like may be provided in the server without being installed in the medical image diagnostic apparatus. Further, the operation history may be recorded in the server without being recorded in the recording unit 12 of the medical image diagnostic apparatus.
