PROBLEM TO BE SOLVED: To provide ultrasonic diagnostic equipment capable of sufficiently carrying out an ultrasonic diagnostic function, and an attachment for use in the same.SOLUTION: Ultrasonic diagnostic equipment of an embodiment has an attachment that is configured in such a manner as to be capable of being freely attached to/detached from an ultrasonic probe and that carries out a partial function of diagnosis including an inspection together with the ultrasonic probe, when attached. The ultrasonic probe has reading means for reading intrinsic information including manufacture information and/or a use history, affecting accuracy when carrying the function.

Description

  The present invention relates to an ultrasonic diagnostic apparatus and an attachment used therefor.

  The ultrasonic diagnostic apparatus has an ultrasonic probe that converts an applied pulse signal into an ultrasonic beam and converts a reflected wave into an echo signal, transmits the ultrasonic beam to the human body, receives the reflected wave, The shape, function, etc. are measured.

  In the ultrasonic diagnosis, when a patient is diagnosed, an attachment attached to the ultrasonic probe may be attached and used. Examples of the attachment include a puncture adapter, a water bag, and a position sensor. The attachment has its ideal processing accuracy (nominal value) and manufacturing variation (tolerance). As the specification value, a range value is determined in consideration of the nominal value and tolerance.

  If the processed dimension of the manufactured attachment is within the range defined as the specification value, it is shipped as a non-defective product and used for ultrasonic diagnosis.

  Here, ultrasonic diagnosis will be described using a puncture adapter having a puncture guide as an example. When collecting a living tissue (affected part) such as cancer, attach a puncture adapter to the ultrasonic probe and superimpose a guideline corresponding to the entry path of the puncture needle on the ultrasonic image based on the specification value of the puncture adapter. indicate. Next, the target affected part is positioned on the guideline by moving the ultrasonic probe. Next, the puncture needle is moved while being guided by the puncture guide, and the puncture needle reaches the target affected area.

JP 2001-046373 A

  However, although the guideline is displayed in the conventional ultrasonic diagnostic apparatus, the guideline represents the ideal processing accuracy (nominal value), and the manufacturing variation (tolerance) that occurs in each puncture adapter is reflected. Not. For example, when the variation is large, the puncture needle may not reach the target affected part even if the target affected part is positioned on the guideline. For this reason, there has been a problem that the function of ultrasonic diagnosis as an attachment cannot be sufficiently performed.

  This embodiment solves the above-described problem, and an object thereof is to provide an ultrasonic diagnostic apparatus capable of sufficiently fulfilling the function of ultrasonic diagnosis and an attachment used therefor.

  In order to solve the above-described problem, the ultrasonic diagnostic apparatus according to the embodiment is configured to be detachable from the ultrasonic probe, and has an attachment that performs a part of a diagnosis function including an inspection together with the ultrasonic probe when the ultrasonic diagnostic apparatus is attached. The ultrasonic probe has reading means for reading unique information including manufacturing information and / or usage history affecting the accuracy when performing the function.

The flowchart which shows a series of flow of reading of specific information.

  This embodiment is configured to be attachable to and detachable from the ultrasonic probe, and is applied to all attachments that perform the function of ultrasonic diagnosis together with the ultrasonic probe. Examples of the attachment include a puncture adapter, a water bag, and a position sensor.

  Here, the puncture adapter is attached to the ultrasonic probe and has a function of fixing the puncture direction of the puncture needle by forming an entry path with a puncture guide. The guideline corresponding to this approach route is displayed on the monitor. Since the user places the target affected part on the guideline and then enters the guide while guiding the puncture needle through the puncture guide, the target affected part can be collected easily, safely and reliably. However, if the approach path and the guideline do not correspond exactly due to the processing dimensions of the puncture guide, the puncture needle will not reach the target affected part even if the target affected part is positioned on the guideline. The function of is reduced. The puncture direction corresponds to the “movement direction”.

  The water bag is attached to the ultrasonic probe and has a function of adjusting the distance between the ultrasonic probe 2 and the body surface according to the amount of water to be added. The water bag is used after being washed, disinfected, and sterilized. For example, if the effect of washing or the like decreases due to long-term use, the use of the water bag is hindered.

  The position sensor is attached to an ultrasonic probe, and a magnetic generator is arranged near the patient. For example, spatial position information (coordinate axes) is sent to the main body of the ultrasonic diagnostic apparatus by the position sensor and acquired in advance within the main body. By performing positioning with other modalities (for example, CT, MRI, etc.) of the same patient, it has a function of synchronously displaying the same CT image and MPR image as the ultrasound image in real time. If there is a deviation in the processing dimension of the position sensor, the identity between the ultrasonic image and the CT image is impaired, and the function of the position sensor is degraded.

  In order to sufficiently perform the function of ultrasonic diagnosis, it is only necessary to reflect the attachment-specific information in the ultrasonic diagnosis and improve the accuracy thereof. Examples of the unique information include attachment manufacturing information and / or usage history.

  The manufacturing information includes, for example, the processing dimension of the puncture guide that greatly affects the function of the puncture adapter, and the processing dimension of the position sensor that significantly affects the function of the position sensor.

  In addition, the usage history includes the number of usages, the number of years of use, and the usage time of attachments that greatly affect the function of the attachment (eg, puncture adapter, water bag, position sensor, etc.). The number of uses is the number of times when the attachment is attached to the ultrasonic probe. Here, the “number of times when attached” refers to the number of times stored in the IC tag 61 (described later) when the attachment is attached to the ultrasonic probe 2. The age of use refers to the number of years that have elapsed since the attachment was first used. The usage time is a time obtained by accumulating the elapsed time from the start of attachment attachment to the removal.

[Basic configuration]
A basic configuration of the ultrasonic diagnostic apparatus will be described with reference to FIG. FIG. 1 is a block diagram illustrating the configuration of an ultrasonic diagnostic apparatus, and FIG. 2 is a diagram schematically illustrating an ultrasonic probe to which an attachment is attached and a main body.

  As shown in FIGS. 1 and 2, in the ultrasonic diagnostic apparatus, a probe 2 having a transducer 22 that transmits and receives ultrasonic waves is connected to a transmission / reception circuit 11 in the main body 1 by a cable C.

  The transmission / reception circuit 11 includes a drive unit 12 and a control unit 13. The drive unit 12 generates a pulse (transmission signal) applied to the transducer 22 and performs processing such as amplification of a reception signal (reception echo) from the transducer 22. This amplified received signal (in some cases, a signal that has also been converted to digital data) is provided to the signal processing system 3, where it is used for ultrasonic images such as B-mode images, Doppler images, and M-mode images. Signal data is obtained. This signal data is converted into a video format by the display system 4 and output as an ultrasonic image to an image display device such as the monitor 5.

  The control unit 13 generates a control signal for controlling on / off of a switch element (not shown) for switching the transducer in the probe 2. The display system 4 includes display control means 41. The display control means 41 and the monitor 5 are examples of “display means”.

[First Embodiment]
The ultrasonic diagnostic apparatus according to the first embodiment will be described with reference to FIGS. 1 and 2.
As shown in FIG. 1, the ultrasonic probe 2 includes a reader / writer 21 that reads unique information of the attachment 6. The reader / writer 21 is an example of a “reading unit”. The reader / writer 21 has a loop antenna (not shown) that receives the unique information of the attachment 6.

  The attachment 6 has an IC tag 61. The IC tag 61 has a storage medium that stores the unique information of the attachment 6 and a loop antenna (not shown) that transmits the unique information. The IC tag 61 is an example of a “storage medium”. When the attachment 6 is attached to the ultrasonic probe 2, for example, the control unit 13 detects the attachment and sends a reading command to the reader / writer 21, whereby the unique information is obtained by wireless communication using the mutual loop antenna. Is read by the reader / writer 21. By attaching the attachment 6 to the ultrasonic probe 2, the unique information can be automatically read, so that the user does not have to input the unique information.

  The IC tag 61 does not need to be provided integrally with the attachment 6 and may be provided separately from the attachment 6. For example, the IC tag 61 and the attachment 6 are provided so as to be associated with each other, and the ultrasonic probe 2 is held over the predetermined IC tag 61 so that the unique information of the predetermined attachment 6 can be read by wireless communication. May be.

  The storage medium capable of storing the unique information is not limited to the IC tag 61, and may be a semiconductor memory such as a flash memory, a CF (CompactFlash) card, or a smart media.

  The semiconductor memory may be provided integrally with the attachment 6, or may be provided separately from the attachment 6. When provided integrally with the attachment 6, the semiconductor memory is preferably small. In this case, the unique information is read from the semiconductor memory by wired communication. When provided separately from the attachment 6, the semiconductor memory is set in the ultrasonic probe 2 so that the unique information can be read.

  As shown in FIGS. 1 and 2, a cable C is provided for passing a pulse signal from the main body 1 to the ultrasonic probe 2 and passing an echo signal from the ultrasonic probe 2 to the main body 1. The cable C has a signal line for transmitting unique information from the ultrasonic probe 2 to the main body 1 in addition to a signal line for passing a pulse signal and an echo signal. Since the unique information can be transmitted from the ultrasonic probe 2 to the main body 1 using the existing cable C, there is no need to separately provide a dedicated cable for transmitting the unique information, and the ultrasonic probe by providing the dedicated cable. 2 can be prevented from deteriorating.

  Hereinafter, a puncture adapter will be described as an example of the attachment 6. The puncture adapter has a puncture guide 62. The control unit 13 includes a calculation unit 131.

  The unique information regarding the puncture adapter is the processing dimension of the puncture guide 62. Here, the processing dimension will be described as a value (measurement value) obtained by measuring the inclination angle of the puncture guide 62. This inclination angle (measured value) includes variations in manufacturing of the puncture guide 62.

  In FIG. 2, the central axis of the spread angle (directivity angle) of the ultrasonic beam transmitted from the ultrasonic probe 2 is indicated by “L0”, and the approach path of the puncture needle guided by the puncture guide 62 is indicated by “L1”. The inclination angle of the approach route L1 with respect to the central axis L0 is indicated by “θ”, and the guideline displayed on the monitor 5 is indicated by “f”.

  A guideline f on the screen of the monitor 5 corresponding to the entry route L1 of the puncture guide 62 is expressed by the following equation.

ここで、θは測定値としての傾き角である。
なお、測定値θは、前もって超音波プローブ２に穿刺アダプタを装着して、その穿刺針の傾斜を測定したときの値をＩＣタグ６１に記憶させておいたものである。

Here, θ is an inclination angle as a measured value.
The measured value θ is a value stored in the IC tag 61 in advance when the puncture adapter is attached to the ultrasonic probe 2 and the inclination of the puncture needle is measured.

  According to the first embodiment, when the puncture adapter is attached to the ultrasonic probe 2, the reader / writer 21 reads the tilt angle (measured value) θ of the puncture guide 62 stored in the IC tag 61. The read inclination angle θ is sent to the control unit 13 through the cable C. The calculation means 131 calculates the guideline f by the above formula (1) based on the inclination angle θ. The display control means 41 displays the ultrasonic image formed by the signal processing system 3 on the monitor 5 based on the echo signal from the ultrasonic probe 2 and displays the guideline f on the monitor 5 so as to overlap the ultrasonic image.

  FIG. 3A is a diagram showing a target affected part located outside the guideline, and FIG. 3B is a diagram showing a target affected part located on the guideline. The target affected part in the ultrasonic image is indicated by “D”, and the guideline is indicated by “f”.

  As shown in FIG. 3A, when the target affected part D is not positioned on the guide line f, the target probe D is positioned on the guide line f by moving the ultrasonic probe 2 as shown in FIG. 3B. . As a result, if the puncture needle 62 is guided and moved by the puncture guide 62, the puncture needle can reach the target affected area D more accurately.

  In the above embodiment, the unique information regarding the puncture adapter is the tilt angle (measured value) θ including the variation in manufacturing of the puncture guide 62, and the guideline f is obtained based on the tilt angle θ. However, this was a reflection of manufacturing variations. Therefore, it has become more accurate to make the puncture needle reach the target affected part D.

  On the other hand, the unique information regarding the puncture adapter may be a predetermined processing dimension (nominal value) of the puncture guide 62 and a correction value resulting from individual manufacturing variations of the puncture guide 62. The correction value is stored in the IC tag 61. The nominal value may be stored in the IC tag 61 or may be stored in the internal memory of the control unit 13. In the following description, it is assumed that the nominal value is stored in the IC tag 61.

  When the puncture adapter is attached to the ultrasonic probe 2, the reader / writer 21 reads the nominal value and the correction value stored in the IC tag 61. The read nominal value and correction value are sent to the control unit 13.

  The calculating means 131 corrects the nominal value with the correction value and obtains the guideline f. The display control means 41 displays the guideline f on the monitor 5 so as to overlap the ultrasonic image.

ここで、αは公称値としての傾き角、βは補正値である。

Here, α is an inclination angle as a nominal value, and β is a correction value.

  In this example, the puncture guide 62 corrects the nominal value based on the correction value caused by the manufacturing variation of each individual, thereby enabling to display a more accurate guideline reflecting the manufacturing variation superimposed on the ultrasonic image. . As a result, if the target affected part in the ultrasonic image is positioned on the guideline and the puncture needle 62 is guided and moved by the puncture guide 62, the puncture needle can reach the target affected part more accurately.

  Next, a series of ultrasonic diagnosis operations using the puncture adapter will be described with reference to FIGS. FIG. 4 is a flowchart showing a series of operations from attachment of a puncture adapter to display of a guideline. Here, an example is shown in which a guideline is obtained based on a predetermined inclination angle (nominal value) of the puncture guide 62 and its correction value, and the guideline is displayed.

  As shown in FIG. 4, it is determined whether or not the puncture adapter is attached to the ultrasonic probe 2 (S101).

  When it is determined that the puncture adapter is attached (S101: Y), for example, the control unit 13 receives a detection signal from a detection switch (not shown) and sends a reading command to the reader / writer 21. The reader / writer 21 reads the format of the puncture adapter stored in the IC tag 61 (S102).

  Next, the reader / writer 21 reads the unique information of the puncture adapter stored in the IC tag 61 (S103).

  FIG. 5 is a flowchart showing a series of operations for reading the unique information of the puncture adapter. As shown in FIG. 5, the inclination angle (nominal value) of the puncture guide 62 is read from the IC tag 61 (S201). Next, the correction value resulting from the manufacturing variation of the puncture guide 62 is read from the IC tag 61 (S202). The nominal value may be stored in advance in the internal memory of the control unit 13.

Next, it is determined whether there is a guideline display request (S104).
When it is determined that there is a guideline display request (S104: Y), the position information is corrected (S105).

  FIG. 6 is a flowchart showing a series of operations for correcting the position information of the puncture guide 62. As shown in FIG. 6, the calculation means 131 corrects a predetermined inclination angle (nominal value) of the puncture guide 62 based on the correction value (S301). Next, the calculation means 131 obtains a guideline by the above formula (2) based on the corrected value (302).

  Next, the display control means 41 causes the monitor 5 to display the ultrasound image formed by the signal processing system 3 based on the echo signal from the ultrasound probe 2 and causes the monitor 5 to display the guideline superimposed on the ultrasound image. (S106). At this time, by positioning the target affected area on the guideline calculated by the calculating means 131, the user can easily, safely and reliably reach the target affected area with the puncture needle.

[Second Embodiment]
Next, a second embodiment will be described with reference to FIGS.
In the second embodiment, the configuration different from the first embodiment is mainly described, and the description of the same configuration is omitted.

  2nd Embodiment demonstrates the structure for improving the precision of a puncture adapter by displaying the use log | history of a puncture adapter by taking a puncture adapter as an example.

  Here, the specific information regarding the puncture adapter is a use history (for example, the number of use times, the number of years used, and the use time are included) when the attachment 6 is attached to the ultrasonic probe 2. The usage history is stored in the IC tag 61.

  Hereinafter, the number of uses will be described as an example of the use history. When the puncture adapter is attached to the ultrasonic probe 2, the controller 13 detects the attachment and sends a reading command to the reader / writer 21. The reader / writer 21 reads a use history (including a predetermined correspondence count M and a mount count N at the time of attachment) from the IC tag 61. Further, the reader / writer 21 adds 1 to the number N of times when it is attached (N + 1), and writes the added value to the IC tag 61. In this way, the usage history is updated (N = N + 1).

  The read usage history is sent to the control unit 13 through the cable C. The control unit 13 sends the read usage history to the display control means 41. The display control means 41 displays the usage history on the monitor 5.

  Further, the display control means 41 causes the monitor 5 to display a corresponding number of times M in which the performance or function of the puncture adapter is assumed to be deteriorated in advance and the number of times N when the puncture adapter is attached. When the number N of times of wearing exceeds a predetermined number of correspondences M (N> M), the user exchanges a new puncture adapter. This prevents a decrease in diagnostic accuracy due to the use of a deteriorated puncture adapter.

  Note that when the calculation means 131 determines that the number N of attachments exceeds a predetermined correspondence number M (N> M), the display control means 41 displays a warning on the monitor 5. Thereby, the user can easily visually recognize the replacement time of the puncture adapter.

  Next, a series of ultrasonic diagnostic operations using the puncture adapter will be described with reference to FIGS. FIG. 7 is a flowchart showing a series of operations based on the use history of the puncture adapter, and FIG. 8 is a flowchart showing a series of flows for reading / writing the unique information.

  As shown in FIG. 7, it is determined whether or not the puncture adapter is attached to the ultrasonic probe 2 (S401).

  When it is determined that the puncture adapter is attached (S401: Y), the reader / writer 21 reads the format of the puncture adapter (S402).

  Next, the reader / writer 21 reads the unique information of the puncture adapter (S403).

  FIG. 8 is a flowchart showing a series of operations for reading / writing unique information of the puncture adapter.

  As shown in FIG. 8, a predetermined inclination angle (nominal value) of the puncture guide 62 is read (S501). Next, a correction value including variations in manufacturing of the puncture guide 62 is read (S502). Next, the use history of the puncture adapter (including the predetermined number of times M and the number of times N when the puncture adapter is attached) and the date of manufacture are read (S503). The read unique information is sent to the control unit 13.

  Next, the calculation means 131 determines whether or not it is within the corresponding years (the number of years allowed for the performance and function of the attachment not to deteriorate) based on the date and time of manufacture and the date of manufacture. It is determined whether or not the number of times N is within a predetermined number of correspondences M (the number of times allowed for the performance and function of the attachment not to deteriorate) (S404). When it is determined that it is not within the corresponding year or not within the corresponding number of times M (S404: N), the display control means 41 displays a warning on the monitor 5.

  When the calculation unit 131 determines that the number of corresponding years is within the corresponding number of years and the number of correspondences is within the number M (S404: Y), it is determined whether there is a guideline display request (S405).

  When it is determined that there is a guideline display request (S405: Y), the position information of the puncture guide 62 is corrected (S406).

  A series of operations for correcting the position information of the puncture guide 62 is as described above. That is, as shown in FIG. 6, the calculation means 131 corrects a predetermined inclination angle (nominal value) of the puncture guide 62 based on the correction value (S301). Next, the calculation unit 131 obtains a guideline based on the corrected value (302).

  Next, the display control unit 41 causes the monitor 5 to display the guideline superimposed on the ultrasonic image (S407). At this time, by positioning the target affected part on the guideline, the user can easily, safely and reliably reach the target affected part with the puncture needle.

  Next, the reader / writer 21 writes the usage history in the IC tag 61. For example, the reader / writer 21 adds one to the number of times N when the reader / writer 21 is mounted (N + 1), and writes the added value to the IC tag 61 (N = N + 1).

  The second embodiment has been described above by taking the puncture adapter as an example. However, the attachment attached to the ultrasonic probe 2 is not limited to the puncture adapter, and may be a water bag, a position sensor, or the like. By referring to each unique information, the accuracy of the attachment can be improved.

FIG. 9 is a functional block diagram illustrating an example of a water bag as an attachment.
As shown in FIG. 9, the IC tag 61 stores a water bag usage history (a predetermined number of times M, a number N of times of attachment, and a manufacturing date). When the water bag is attached to the ultrasonic probe 2, the reader / writer 21 reads the use history of the water bag from the IC tag 61. In addition, the reader / writer 21 adds 1 to the number N of attachments (N + 1), and writes the added value in the IC tag 61.

  The display control means 41 causes the monitor 5 to display a predetermined number of correspondences M and the number of times of attachment N that can be compared.

[Third Embodiment]
Next, a third embodiment will be described with reference to FIGS.
Note that in the third embodiment, a configuration different from that of the first embodiment will be mainly described, and description of the same configuration will be omitted.

  In the third embodiment, a configuration for improving the positional accuracy of the ultrasonic probe 2 by reflecting the processing dimensions of the position sensor due to manufacturing variations will be described using the position sensor as an example of the attachment 6.

  The position sensor is attached to a predetermined processing dimension (nominal value) of the ultrasonic probe 2 and is configured to detect position information of the ultrasonic probe 2 of the ultrasonic probe 2. The unique information regarding the position sensor includes a machining dimension (nominal value) and a correction value for the nominal value.

FIG. 10 is a block diagram of the configuration of the ultrasonic diagnostic apparatus.
As shown in FIG. 10, the reader / writer 21 reads unique information (nominal value and correction value) from the IC tag 61 and sends it to the control unit 13 through the cable C. The calculation unit 131 obtains position information of the ultrasonic probe 2 based on the nominal value and the correction value. The display control unit 41 causes the monitor 5 to display the position information of the ultrasonic probe 2 when the ultrasonic control probe 2 is mounted on the obtained ultrasonic probe 2.

  The position information of the ultrasonic probe 2 is expressed by the following equation.

ここで、ｘ、ｙ、ｚは公称値、γ、δ、εは補正値である。

Here, x, y, and z are nominal values, and γ, δ, and ε are correction values.

  Next, a series of ultrasonic diagnosis operations using the puncture adapter will be described with reference to FIGS. FIG. 11 is a flowchart showing a series of operations from mounting the position sensor to displaying the position information of the ultrasonic probe.

  As shown in FIG. 11, it is determined whether or not a position sensor is attached to the ultrasonic probe 2 (S601).

  When it is determined that the position sensor is attached (S601: Y), the reader / writer 21 reads the format of the position sensor (S602).

  Next, the reader / writer 21 reads the unique information of the position sensor (S603).

  FIG. 12 is a flowchart showing a series of operations for reading the unique information of the position sensor. As shown in FIG. 12, the nominal value is read from the IC tag 61 (S701). Next, the correction value is read from the IC tag 61 (S702).

  Next, it is determined whether or not there is a display request for position information of the ultrasonic probe 2 (S604).

  When it is determined that there is a request to display the position information of the ultrasonic probe 2 (S604: Y), the position information of the ultrasonic probe 2 is corrected (S605).

  A series of operations for correcting the position information of the ultrasonic probe 2 is as follows. That is, the calculation unit 131 corrects the nominal value based on the correction value, and obtains corrected position information of the ultrasonic probe 2.

  Next, the display control means 41 displays the corrected position information of the ultrasonic probe 2 on the monitor 5 (S606). Thereby, the user can perform ultrasonic diagnosis while confirming the corrected position information.

  In this embodiment, a puncture adapter, a water bag, and a position sensor are shown as examples of attachments, but the present invention is not limited to this.
