Description

  The present invention is directed to an ultrasonic diagnostic apparatus capable of improving the quality and efficiency of ultrasonic examination and treatment, and the like, even when an operator performs transmission and reception of ultrasonic waves by an ultrasonic probe while looking at the hand. It relates to the control program.

  In an ultrasonic diagnostic apparatus, an ultrasonic image inside a subject can be observed in real time. While the operator is observing the display unit on which the ultrasonic image is displayed, it may be necessary to look at the hand holding the ultrasonic probe that transmits and receives the ultrasonic wave to and from the subject. For example, when performing a puncture under an ultrasonic guide, the operator looks at an actual puncture needle with respect to the insertion position and angle of the puncture needle, or views a positional relationship between the puncture needle and the ultrasonic probe. It is necessary to confirm. Also, when the operator records an ultrasonic image on the ultrasonic diagnostic apparatus while observing the movement of the subject's body, such as inclination, breathing, and convulsions, the examination is performed while alternately viewing the ultrasonic image and the hand. It is necessary to do. In addition, when the operator performs an examination with the ultrasonic probe positioned between the ribs of the subject and it is difficult to find the desired transmitting / receiving surface due to the narrow ribs, the operator alternates between the ultrasonic image and the hand. It is necessary to carry out the inspection while watching.

  By the way, in some cases, the operator sets a marker in an ultrasonic image at a target portion where a puncture needle is inserted, for example. The setting of the marker is performed before inserting the puncture needle. Therefore, the operator first displays an ultrasonic image of a desired cross section, and then sets a marker in the ultrasonic image. The ultrasonic probe is provided with a position sensor for detecting a position in a three-dimensional space, and by setting a marker in an ultrasonic image, the position of the marker in the three-dimensional space is stored (for example, see Patent Reference 1).

  After setting the marker, the operator once puts the ultrasonic probe to prepare for inserting the puncture needle. When the preparation for inserting the puncture needle is ready, the position and angle of the ultrasonic probe are adjusted so that the position where the marker is set is included in the ultrasonic transmission / reception surface, and the marker is displayed again on the ultrasonic image. .

  In addition, there is a method of measuring the elasticity of a living tissue of a subject by generating ultrasonic waves transmitted from an ultrasonic probe and generating a shear wave in the subject, and measuring the propagation speed of the shear waves ( For example, see Patent Document 2). In this measurement method, while the operator stops the ultrasonic probe and the subject holds his / her breath, the ultrasonic image is stopped. Generate waves.

  As described above, when the operator adjusts the position of the ultrasonic probe to display the marker again on the ultrasonic image or stops the ultrasonic probe to perform elasticity measurement using the shear wave. In some cases, it is necessary to look at the hand. Therefore, even if the operator can see that the position of the ultrasonic transmission / reception surface or the moving speed of the ultrasonic transmission / reception surface has reached a predetermined position or speed, the ultrasonic inspection It is expected to improve the quality and efficiency of treatment and treatment.

  The control unit 8 is a processor such as a CPU (Central Processing Unit). The control unit 8 reads the program stored in the storage unit 9 and controls each unit of the ultrasonic diagnostic apparatus 1. For example, the control unit 8 reads a program stored in the storage unit 9 and causes the functions of the transmission / reception beamformer 3, the echo data processing unit 4, and the display processing unit 5 to be executed by the read program.

  The control unit 8 may execute all of the functions of the transmission / reception beamformer 3, all of the functions of the echo data processing unit 4, and all of the functions of the display processing unit 5 by a program, Only some functions may be executed by a program.

  The functions of the transmission / reception beamformer 3, the echo data processing unit 4, and the display processing unit 5 may be realized by hardware such as a circuit.

  In addition, the control unit 8 causes a program to execute a determination function by the determination unit 81 and a light emission control function by the light emission control unit 82 illustrated in FIG. The determination unit 81 determines whether the position of the transmission / reception surface has reached a predetermined position based on the position coordinates of the transmission / reception surface of the ultrasonic wave specified by the position specification unit 51.

  The light emission control unit 82 changes the light emission state of the light emitting unit 12. Details will be described later. The light emission control unit 82 is an example of an embodiment of the light emission control unit according to the present invention.

  The storage unit 9 is an HDD (Hard Disk Drive: hard disk drive), a semiconductor memory (Memory) such as a RAM (Random Access Memory) or a ROM (Read Only Memory).

  The ultrasound diagnostic apparatus 1 may include all of the HDD, the RAM, and the ROM as the storage unit 9. The storage unit 9 may be a portable storage medium such as a CD (Compact Disk) or a DVD (Digital Versatile Disk).

  The program executed by the control unit 8 is stored in a non-transitory storage medium such as an HDD or a ROM. Further, the program may be stored in a portable and non-transitory storage medium such as a CD or a DVD.

  Now, the operation of the ultrasonic diagnostic apparatus 1 of the present example will be described. Here, an operation in the case of cauterizing an affected part such as a tumor using a puncture needle will be described.

  First, the operator sets the marker MK in the ultrasonic image UI as shown in FIG. The operator first adjusts the position and angle of the ultrasonic probe 2 so that an ultrasonic image UI of a desired cross section D including a target to be inserted with a puncture needle such as a tumor is displayed on the display unit 6.

  When the ultrasonic image UI for the desired section D is displayed, the operator performs an input on the operation unit 7 to display the marker MK. Based on this input, the marker setting unit 52 causes the display unit 6 to display the marker MK. Then, when the operator performs an input for moving the marker MK using the trackball or the like of the operation unit 7, the marker setting unit 52 moves the marker MK based on the input. When the operator performs an input to determine the position of the marker MK at the position to be inserted with the puncture needle in the operation unit 7, the marker setting unit 52 sets the marker in the three-dimensional space with the magnetism generation unit 11 as the origin. The position coordinates of the MK are specified, and the position coordinates are stored in the storage unit 9.

  The marker setting unit 52 specifies the position coordinates of the marker MK in the three-dimensional space based on the position coordinates of the transmitting / receiving surface of the ultrasonic wave specified by the position specifying unit 51 and the position of the marker MK in the ultrasonic image UI. .

  Next, the operator suspends the transmission and reception of the ultrasonic wave at the desired cross section D and places the ultrasonic probe 2 to prepare for inserting the puncture needle. When the preparation for inserting the puncture needle is completed, the operator adjusts the position and angle of the ultrasonic probe 2 so that the ultrasonic image UI for the desired cross section D is displayed again.

  The determining unit 81 determines whether or not the transmitting / receiving surface of the ultrasonic wave whose position coordinates in the three-dimensional space are detected by the position specifying unit 51 includes the position coordinates of the marker MK set in the three-dimensional space. . Then, when the position coordinates of the marker MK are included in the transmitting / receiving surface of the ultrasonic wave, the determining unit 81 determines that the position of the transmitting / receiving surface of the ultrasonic wave has reached a predetermined position.

  When the determining unit 81 determines that the position coordinates of the marker MK are included in the transmitting / receiving surface of the ultrasonic wave, the light emission control unit 82 causes the light emitting unit 12 to emit light. On the other hand, when the determination unit 81 determines that the position coordinates of the marker MK are not included in the transmitting / receiving surface of the ultrasonic wave, the light emission control unit 82 does not cause the light emitting unit 12 to emit light. Therefore, the light emission control unit 82 changes the light emission state of the light emitting unit 12 depending on whether or not the position coordinates of the marker MK are included in the transmission / reception surface of the ultrasonic wave.

  When the operator confirms that the light emitting unit 12 has emitted light, the operator starts cauterization treatment with a puncture needle.

  According to the present example, even if the operator looks at the hand without looking at the display unit 6, the light emitting unit 12 emits light, and the transmitting / receiving surface of the ultrasonic wave has a cross section including the position where the marker MK is set. You can know that it has become. Therefore, if the operator wants to check the puncture needle itself or the positional relationship between the puncture needle and the ultrasonic probe 2 and check the insertion position and angle of the puncture needle, without looking at the ultrasonic image, Since it is possible to know that the transmitting / receiving surface of the ultrasonic wave is located on the cross section including the target into which the puncture needle is inserted, it is expected to improve the quality and efficiency of the ultrasonic examination and the treatment.

  Next, a modification of the first embodiment will be described. In this example, the control unit 8 causes a program to execute a distance calculation function by a distance calculation unit 83 shown in FIG. 6 in addition to a determination function by the determination unit 81 and a light emission control function by the light emission control unit 82.

  The distance calculation unit 83 calculates the distance between the position coordinates of the marker MK set in the three-dimensional space having the origin of the magnetism generation unit 11 and the position of the transmitting / receiving surface of the ultrasonic wave specified by the position specifying unit 51. The distance here is, for example, the shortest distance between the position coordinates of the marker MK and the position of the transmitting / receiving surface.

  The determining unit 81 determines whether or not the distance X calculated by the distance calculating unit 83 is equal to or less than a predetermined distance Xth (X ≦ Xth). The determining unit 81 determines that the position of the transmitting / receiving surface of the ultrasonic wave has become the predetermined position when the distance X calculated by the distance calculating unit 83 is equal to or less than the predetermined distance Xth.

  When the determination unit 81 determines that X ≦ Xth (where X ≠ 0), the light emission control unit 82 causes the light emitting unit 12 to emit light at the first luminance Br1. On the other hand, when the determination unit 81 determines that X> Xth, the light emission control unit 82 does not cause the light emitting unit 12 to emit light.

  When the determination unit 81 determines that the position coordinates of the marker MK are included in the transmission / reception surface of the ultrasonic wave, the light emission control unit 82 causes the light emission unit 12 to emit light at the second luminance Br2. The second luminance Br2 is higher than the first luminance Br1 (Br2> Br1).

  According to this modification, when the transmitting / receiving surface of the ultrasonic wave approaches the position where the marker MK is set, the light emitting unit 12 emits light at the first luminance Br1, and the transmitting / receiving surface of the ultrasonic wave has the marker MK set. When the position is included, the light emitting unit 12 emits light at the second luminance Br2. As described above, the light emitting state of the light emitting unit 12 changes according to the distance between the ultrasonic wave transmitting / receiving surface and the position coordinates of the marker MK. Therefore, the operator pays attention to the light emitting state of the light emitting unit 12 while looking at the hand. This makes it possible to more easily position the transmitting / receiving surface of the ultrasonic wave so as to include the puncture target of the puncture needle.

  The light emitting unit 12 may emit light in different colors. In this case, in the above description, the emission color of the light emitting unit 12 may be changed according to the distance between the ultrasonic wave transmitting / receiving surface and the position coordinates of the marker MK. That is, when the determination unit 81 determines that X ≦ Xth (where X ≠ 0), the light emission control unit 82 causes the light emitting unit 12 to emit light in the first color Cl1. When the determination unit 81 determines that the position coordinates of the marker MK are included in the transmission / reception surface of the ultrasonic wave, the light emission control unit 82 causes the light emission unit 12 to emit light in the second color Cl2.

  The light emitting unit 12 may be configured by a liquid crystal display 121, as shown in FIG. 7, instead of the LED. In this case, the emission color of the liquid crystal display 121 may be changed.

  Further, as shown in FIG. 8, the light emitting unit 12 may be configured by a plurality of light emitting units 12A, 12B, 12C, 12D, and 12E. In this case, the predetermined distance Xth may be a plurality of different distances Xth1, Xth2, Xth3, Xth4 (Xth1> Xth2> Xth3> Xth4> 0). The determining unit 81 determines whether or not the distance X calculated by the distance calculating unit 83 is equal to or less than the distances Xth1, Xth2, Xth3, and Xth4.

  When the determination unit 81 determines that Xth2 <X ≦ Xth1, the light emission control unit 82 causes the light emitting unit 12A to emit light, and does not cause the other light emitting units 12B to 12E to emit light. When the determination unit 81 determines that Xth3 <X ≦ Xth2, the light emission control unit 82 causes the light emitting units 12A and 12B to emit light and does not emit light from the other light emitting units 12C to 12E. When the determination unit 81 determines that Xth4 <X ≦ Xth3, the light emission control unit 82 causes the light emitting units 12A to 12C to emit light, and does not cause the other light emitting units 12D and 12E to emit light. When the determination unit 81 determines that 0 <X ≦ Xth4, the light emission control unit 82 causes the light emitting units 12A to 12D to emit light and the other light emitting units 12E not to emit light.

  When the determining unit 81 determines that the position coordinates of the marker MK are included in the transmitting / receiving surface of the ultrasonic wave (X = 0), the light emission control unit 82 causes all the light emitting units 12A to 12E to emit light.

  By changing the light emitting state of the plurality of light emitting units 12A to 12E in this manner, the operator can know a finer change in the distance between the ultrasonic transmitting / receiving surface and the position coordinates of the marker MK while looking at the hand. it can.

  However, even when only one light emitting unit 12 is provided, the distance between the transmitting / receiving surface of the ultrasonic wave and the position coordinates of the marker MK is determined because the light emitting unit 12 emits light in different colors. You can know the more detailed change of. That is, the determination unit 81 determines whether or not the distance X calculated by the distance calculation unit 83 is equal to or less than the distances Xth1, Xth2, Xth3, and Xth4, and according to the determination result, the light emission control unit 82 Are emitted in different colors.

  By increasing the number of predetermined distances Xth, the luminance and color of the light emitting unit 12 may be changed continuously.

(Second embodiment)
Next, a second embodiment will be described. However, description of the same items as in the first embodiment will be omitted.

  In this example, the ultrasonic wave transmitted from the ultrasonic probe generates a shear wave in the subject, and the propagation speed of the shear wave is measured. Specifically, as shown in FIG. 9, the echo data processing unit 4 includes a B-mode processing unit 41, a propagation speed calculation unit 42, and an elasticity value calculation unit 43. The B-mode processing unit 41 performs B-mode processing such as logarithmic compression processing and envelope detection processing on the echo data output from the transmission / reception beamformer 3 to generate B-mode data.

  The propagation speed calculation unit 42 calculates the propagation speed of the shear wave based on the echo data output from the transmission / reception beamformer 3. The elasticity value calculator 43 calculates the elasticity value of the living tissue to which the push pulse has been transmitted, based on the propagation speed. The propagation speed and the elasticity are measured values relating to the elasticity of the living tissue.

  Incidentally, only the propagation velocity is calculated, and the elasticity value does not necessarily have to be calculated. The data of the propagation velocity or the data of the elasticity value is referred to as elasticity data.

  Further, as shown in FIG. 10, the display processing unit 5 has a motion detection unit 54. The motion detecting unit 54 detects the motion of the ultrasonic image by performing image correlation calculation on the ultrasonic image data of two temporally different frames of the same part of the subject. The motion of the ultrasonic image includes a motion accompanying the movement of the ultrasonic probe 2 and a motion of the living tissue itself due to a heartbeat or the like. The motion detection unit 54 performs image correlation calculation on a region of interest set in the ultrasound image, and detects the motion of the ultrasound image. The motion detection unit 54 is an example of an embodiment of the motion detection unit according to the present invention.

  As described later, in this example, the determination unit 81 determines whether the moving speed of the transmission / reception surface has reached a predetermined speed based on the position coordinates of the transmission / reception surface of the ultrasonic wave specified by the position specification unit 51. Is determined.

  The operation of the ultrasonic diagnostic apparatus 1 according to the present embodiment will be described. First, the operator displays a B-mode image on the display unit 6 and searches for a desired cross section D ′ for which the elasticity of the living tissue is to be measured. When the operator finds the desired section D ′, the operator stops the ultrasonic probe 2. The determination unit 81 determines whether or not the moving speed of the ultrasonic wave transmitting / receiving surface has become zero based on the position of the ultrasonic wave transmitting / receiving surface specified by the position specifying unit 51. Then, the determining unit 81 determines that the moving speed of the ultrasonic transmitting / receiving surface has reached a predetermined speed when the moving speed of the ultrasonic transmitting / receiving surface has become zero. Incidentally, the movement of the transmission / reception surface is caused, for example, by the operator moving the ultrasonic probe 2 on the body surface or pushing the ultrasonic probe 2.

  Further, the determination unit 81 determines whether or not the motion of the ultrasonic image has been detected by the motion detection unit 54.

  When the determining unit 81 determines that the moving speed of the ultrasonic wave transmitting / receiving surface has become zero and the motion detecting unit 54 determines that the motion of the ultrasonic image is not detected (first case), the light emission control unit 82 causes the light emitting unit 12 to emit light. On the other hand, when the determining unit 81 determines that the moving speed of the ultrasonic wave transmitting / receiving surface is not zero, or when the motion detecting unit 54 determines that the motion of the ultrasonic image is detected (second In this case, the light emission control unit 82 does not cause the light emitting unit 12 to emit light. Therefore, the light emission control unit 82 changes the light emission state of the light emitting unit 12 depending on whether the moving speed of the ultrasonic wave transmitting / receiving surface has become zero and whether the movement of the living tissue itself due to respiration or the like has ceased.

  When the operator confirms that the light emitting unit 12 has emitted light, the operation unit 7 performs an input for transmitting an ultrasonic wave (push pulse) for generating a shear wave to the living tissue of the subject from the ultrasonic probe 2. With this input, an ultrasonic wave for generating a shear wave is transmitted, and the propagation speed of the shear wave is calculated by the propagation speed calculation unit 42. Further, the elasticity value of the living tissue is calculated by the elasticity value calculation unit 43 based on the propagation speed.

  According to the present example, the operator can know that the ultrasonic probe 2 is in a stationary state and there is no movement of the living tissue by emitting light from the light emitting unit 12, so that the ultrasonic wave that generates the shear wave is used. Can be known.

  As described above, the present invention has been described with reference to the above-described embodiments. However, it is needless to say that the present invention can be variously modified without departing from the gist thereof. For example, in the first embodiment, the emission color or luminance of the light emitting unit 12 may change depending on whether the position coordinates of the marker MK are included in the transmitting / receiving surface of the ultrasonic wave or not. Further, in the second embodiment, when it is determined that the moving speed of the transmitting / receiving surface of the ultrasonic wave has become zero and the motion detecting unit 54 determines that the motion of the ultrasonic image is not detected (the first case). When the moving speed of the transmitting / receiving surface of the ultrasonic wave is determined to be not zero or when the motion detecting unit 54 determines that the motion of the ultrasonic image is detected (second case), the light emission is performed. The emission color and brightness of the unit 12 may change.

  In the first embodiment, a plurality of markers MK may be set. In this case, the colors of the markers MK may be different. When the color of the marker MK is different, the light emitting unit 12 may emit light in the same color as the color of the marker MK.
