A user such as a doctor can perform a desired diagnosis by selecting an ultrasound image necessary for diagnosis from a plurality of ultrasound images stored in the image memory and displaying the selected ultrasound image on a monitor or the like.

  When a desired image is selected from a plurality of frames of ultrasonic images, for example, a method in which a user operates a trackball or a keyboard to display an ultrasonic image on a monitor frame by frame and perform a search can be considered. However, with this method, an operation for displaying an ultrasonic image on a monitor is repeatedly performed, and it takes time to select an image.

  Further, a method of finding a desired time phase from a waveform shape using a biological signal such as an electrocardiogram waveform and selecting an ultrasonic image of a frame corresponding to the time phase is also conceivable. However, in this method, since the image is displayed after the time phase is selected, it is not possible to determine whether the image is a desired one at the stage before selection.

  A thumbnail image is known as a display form for selecting a desired image from a plurality of images. For example, Patent Document 1 discloses a technique for forming a display image in which a specific time phase of an electrocardiogram waveform is associated with a thumbnail image at that time phase. Japanese Patent Application Laid-Open No. 2004-228561 discloses a technique for forming a thumbnail image for a moving image file by combining thumbnail images of a start frame and an end frame of a moving image file composed of a plurality of frames.

  Patent Document 3 is a document that will be referred to later when describing a preferred embodiment of the present invention, and discloses a technique related to a velocity vector.

  DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, preferred embodiments of the invention will be described with reference to the drawings.

  FIG. 1 shows a preferred embodiment of an ultrasonic diagnostic apparatus according to the present invention, and FIG. 1 is a block diagram showing the overall configuration thereof.

  The probe 10 is an ultrasonic probe that transmits and receives an ultrasonic wave 50 in a space including a heart that is a target tissue. The probe 10 includes a plurality of vibration elements (not shown), and the plurality of vibration elements are electronically scanned, and an ultrasonic beam is scanned in a space including the target tissue. The probe 10 is used by being held by a user (inspector) and contacting the body surface of the subject. The probe 10 may be used by being inserted into a body cavity of a subject.

  The transmission / reception unit 12 functions as a transmission beam former and a reception beam former. That is, the transmission / reception unit 12 forms an ultrasonic beam by supplying a transmission signal to each of the plurality of vibration elements included in the probe 10, while obtaining a reception signal from each of the plurality of vibration elements. For example, a phasing addition process is performed on a plurality of received signals. Thereby, an echo signal is formed for each ultrasonic beam and output from the transmission / reception unit 12.

  The transmission / reception unit 12 is controlled by the transmission / reception control unit 14 to scan the ultrasonic beam, and acquires an echo signal from the entire area within the scanning plane.

  The tomographic image forming unit 16 forms a tomographic image of the heart that is the target tissue based on the echo signal supplied from the transmitting / receiving unit 12. That is, the tomographic image forming unit 16 executes a well-known B-mode image forming process to form a tomographic image (B-mode image) of the heart for each frame (for each time phase). The tomographic image formed for each frame is stored in the tomographic image storage unit 32. As a result, the tomographic image storage unit 32 stores a plurality of tomographic images (image data) corresponding to a plurality of frames.

  The color Doppler calculation unit 18 forms image data of a color Doppler image based on the echo signal supplied from the transmission / reception unit 12. A well-known technique is used for forming a color Doppler image. That is, speed information at each point of the target tissue is extracted from the echo signal, and a color Doppler image is formed by applying a color corresponding to the speed to each part on the tomographic image of the target tissue. The image data of each frame formed by the color Doppler calculation unit 18 is stored in the color Doppler image storage unit 34. As a result, the color Doppler image storage unit 34 stores a plurality of color Doppler images (image data) corresponding to a plurality of frames.

  The velocity vector calculation unit 20 calculates a two-dimensional velocity vector from the value of the beam direction velocity component at each point obtained by the color Doppler calculation unit 18. For the calculation of the two-dimensional velocity vector, for example, the calculation described in Patent Document 3 (Japanese Patent Laid-Open No. 2005-110939) is used. The outline of the calculation described in this document is as follows.

  First, a blood flow function is calculated by integrating the velocity component in the beam direction at each point along a path orthogonal to the beam. Then, along the path, the integral value of only the positive value of the beam direction velocity component and the integral value of only the negative value are obtained, and the smaller one of them is regarded as the flow rate of the eddy current, and the larger one of the two is obtained. The velocity component in the beam direction of the vortex flow is obtained from the ratio of the flow rate of the vortex flow to. The vortex flow function can be calculated from the value of this component, and the velocity component of the vortex flow in the direction orthogonal to the beam can be calculated from the flow function. Further, the basic flow rate function is obtained by subtracting the flow function from the flow rate function. Thus, the velocity component in each direction of the basic blood flow is obtained from the basic flow rate function, and a two-dimensional velocity vector is obtained.

  The velocity vector calculation unit 20 forms a blood flow velocity vector image based on the obtained two-dimensional velocity vector. As the velocity vector image, for example, an image in which the velocity vector of each point is represented by an arrow is formed on the B-mode image. That is, it is an image in which the velocity at each point of blood flow is represented by an arrow. Further, as the velocity vector image, an image in which streamlines having a tangent to the direction of the velocity vector at each point may be formed on the B-mode image. That is, an image in which blood flow is expressed by streamlines (curves) may be formed. The formed velocity vector image (image data) is stored in the velocity vector image storage unit 36.

  The biological signal waveform generation unit 22 generates a biological signal waveform that changes according to the time phase based on biological information obtained from the subject. That is, the biological signal waveform generation unit 22 generates an electrocardiographic waveform based on an electrocardiographic signal acquired from the subject as biological information via the biological signal input unit 24. The generated electrocardiogram waveform (biological signal waveform) is stored in the biological signal waveform storage unit 38.

  The thumbnail image creating unit 26 forms a plurality of thumbnail images by reducing the ultrasonic images of the respective time phases. That is, the thumbnail image creating unit 26 reduces the tomographic image for each frame formed by the tomographic image forming unit 16 to form a plurality of thumbnail images corresponding to a plurality of frames. Alternatively, the thumbnail image creation unit 26 may reduce the color Doppler image for each frame formed by the color Doppler calculation unit 18 to form a plurality of thumbnail images.

  Furthermore, the thumbnail image creation unit 26 is for attaching a cursor later to a thumbnail image corresponding to a specific time phase in the electrocardiogram waveform based on the electrocardiogram waveform generated by the biological signal waveform generation unit 22. Add identification information. That is, identification information is attached to a thumbnail image corresponding to a specific time phase such as an R wave included in an electrocardiogram waveform. A plurality of thumbnail images (image data) created by the thumbnail image creation unit 26 are stored in the thumbnail image storage unit 40.

  The image control unit 30 is based on a user instruction input via the input device 28, and includes a tomographic image storage unit 32, a color Doppler image storage unit 34, a velocity vector image storage unit 36, a biological signal waveform storage unit 38, and a thumbnail. The display image forming unit 42 forms a display image by appropriately extracting the image and waveform stored in the image storage unit 40 and supplying the image and waveform to the display image forming unit 42. The display image formed in the display image forming unit 42 is displayed on the display unit 44.

  Then, the display image displayed on the display unit 44 will be described next. In the following description, the parts already shown in FIG.

  FIG. 2 is a diagram for explaining the display image 100 displayed on the display unit 44. The display image 100 includes an ultrasound image 50, an electrocardiogram waveform 60, and a selection image 70 that are selected by the user.

  The selected image 70 is an image in which a part of a plurality of thumbnail images 76 stored in the thumbnail image storage unit 40 is arranged in a line. That is, the selected image 70 includes nine thumbnail images 76 corresponding to the frame numbers F1 to F9 as shown in FIG. The user compares the plurality of thumbnail images 76 displayed in the selected image 70 with each other to find a thumbnail image 76 corresponding to the desired image. Note that the thumbnail image 76 stored in the thumbnail image storage unit 40 stores a plurality of thumbnail images 76 in addition to the nine thumbnail images 76 corresponding to the frame numbers F1 to F9.

  Therefore, the display image forming unit 42 scrolls and displays the thumbnail images 76 included in the selected image 70. When the thumbnail image 76 is scrolled, scroll buttons 74d and 74u are used. The user operates the scroll button 74d or the scroll button 74u displayed on the screen using the input device 28 such as a mouse, a trackball, or a keyboard. When the scroll button 74d is pressed, the thumbnail image 76 included in the selected image 70 is scrolled to the smaller frame number. On the other hand, when the scroll button 74u is pressed, the thumbnail image 76 included in the selected image 70 has a frame number. Scroll to the larger side.

  For example, when the scroll button 74u is pressed while the thumbnail image 76 of the frame numbers F1 to F9 is displayed as the selected image 70, the 9 of the frame numbers F10 to F18 is substituted for the thumbnail image 76 of the frame numbers F1 to F9. A number of thumbnail images 76 are displayed. Conversely, when the scroll button 74d is pressed while the thumbnail images 76 of the frame numbers F10 to F18 are displayed, the thumbnail images 76 of the frame numbers F1 to F9 are replaced with the thumbnail images 76 of the frame numbers F10 to F18. Is displayed.

  Note that when the scroll button 74d is pressed while the thumbnail images 76 of the frame numbers F1 to F9 are displayed, there is no frame number smaller than the frame number F1, so that the frame number from the largest frame number is 9 A single thumbnail image 76 may be displayed. Conversely, when the scroll button 74u is pressed while nine thumbnail images 76 having the largest frame number are displayed, the thumbnail images 76 of the frame numbers F1 to F9 may be returned. .

  Further, the thumbnail image 76 included in the selected image 70 is not limited to nine (9 frames), and other plural frames may be displayed. Further, the thumbnail image 76 is not limited to the display of only one column as shown in FIG. 2, and the selected image 70 may be configured by a plurality of thumbnail image columns. Further, the thumbnail image 76 included in the selected image 70 is preferably a plurality of continuous frames. However, for example, only the thumbnail image 76 having an even frame number may be displayed, and the frames may be thinned and displayed.

  The user performs a scroll operation or the like to find a desired thumbnail image 76, and performs a selection determination operation in a state where the selection cursor 78 is aligned with the desired thumbnail image 76, whereby the thumbnail image 76 is selected. Note that the selection cursor 78 is realized, for example, by changing the color of the frame of the thumbnail image 76.

  When the thumbnail image 76 is selected, the display image forming unit 42 displays the ultrasonic image 50 corresponding to the selected thumbnail image 76. That is, the ultrasonic image 50 of the time phase (frame) corresponding to the selected thumbnail image 76 is displayed. The display image forming unit 42 uses the tomographic image stored in the tomographic image storage unit 32, the color Doppler image stored in the color Doppler image storage unit 34, or the velocity vector as the ultrasonic image 50 based on a user instruction. The speed vector image stored in the image storage unit 36 is displayed.

  Further, the display image forming unit 42 provides an electrocardiogram cursor 62 corresponding to the time phase of the selected ultrasonic image 50 in the electrocardiogram waveform 60. In other words, an electrocardiographic cursor 62 is provided that clearly indicates at which time point (time phase) in the electrocardiographic waveform 60 the ultrasonic image 50 is. A configuration in which the user moves the electrocardiogram cursor 62 and the selection cursor 78 of the thumbnail image 76 moves according to the position of the electrocardiogram cursor 62 may be adopted. That is, the user may select a desired thumbnail image 76 by operating the electrocardiogram cursor 62.

  Further, the display image forming unit 42 provides an R-wave cursor 72 on the thumbnail image 76 at the time phase corresponding to the R-wave in the electrocardiogram waveform 60. FIG. 2 shows that the thumbnail image 76 with the frame number F1 is an image at the time of the R wave. The R wave cursor 72 is realized, for example, by changing the background color of the frame number.

  As described above, since the plurality of thumbnail images 76 are included in the selected image 70, the user compares the plurality of thumbnail images 76 with each other to confirm a desired content while confirming the image content of the ultrasonic image 50. An image can be selected. Note that the selected ultrasonic image 50 and the selected image 70 may be displayed in the same display area as shown in FIG. 2, or the ultrasonic image 50 is displayed on the main display, and the selected image 70 is displayed on the sub-display. May be displayed.
