Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a medical image display apparatus capable of generating and reproducing browse cut images of moving images and still images.
[0002]
[Prior art]
Conventionally, when a medical image (hereinafter simply referred to as an image) including moving images and still images captured by various medical devices is reproduced and referred to a medical image display device, the captured moving image is a VTR (Video Tape Recorder). While the analog image is stored in the apparatus, the still image is recorded on a recording medium such as a film or a magneto-optical disk.
[0003]
Therefore, when the operator tries to refer to the moving image and the still image alternately, the VTR device and the MO (Magnetic Optical) device are operated and reproduced respectively.
[0004]
Further, when only a moving image is displayed on the VTR device, reproduction and fast-forwarding operations are repeatedly performed until a desired image appears.
[0005]
Furthermore, when it is desired to display a moving image in a range that is a VTR device in a looped manner, a replay operation is performed after a rewind operation.
[0006]
Furthermore, when a moving image is reproduced and displayed on the medical image display device, the next / previous operation is performed to display the still image index, and then the reproduction operation is performed. Further, even when a moving image and a still image are mixed, an index of the still image is displayed and then a reproduction operation is performed.
[0007]
[Problems to be solved by the invention]
However, in the conventional medical image display device, when a desired moving image is reproduced and displayed, the moving image is recorded in the VTR device, so that the image before the target is not seen until the target image is reached. The operation efficiency was low.
[0008]
Also, since moving images were browsed as still images, it was impossible to distinguish between moving images and still images. Further, when displaying a moving image and a still image separately, it is necessary to perform two operations in order to obtain browsing corresponding to one examination by displaying the moving image and the still image on separate screens.
[0009]
The present invention has been made in view of the above, and an object of the present invention is to provide a medical image display apparatus capable of efficiently generating and reproducing a browse cut image obtained by connecting images.
[0010]
[Means for Solving the Problems]
The invention described in claim 1 is a medical image display device that reproduces and displays a medical image including a captured moving image or still image in order to solve the above-described problem, and selects an arbitrary image of the moving image. Means, image editing means for editing a plurality of selected images as a series of browse cut images, and continuous playback means for continuously playing back a series of edited browse cut images on a display screen. The gist.
[0011]
In the first aspect of the present invention, after selecting an arbitrary image of a moving image and editing the selected plurality of images as a series of browse cut images, the edited series of browse cut images are continuously displayed. Reproduction on the display screen has an effect that the browse cut image obtained by connecting the images can be efficiently generated and reproduced.
[0012]
In order to solve the above-mentioned problem, the gist of the invention is that the image selecting means selects from a moving image for one heartbeat.
[0013]
According to the second aspect of the present invention, by selecting from moving images for one heartbeat, there is an effect of preventing overlapping of heartbeat images in the same image.
[0016]
In order to solve the above-mentioned problem, the invention described in claim 3 has an operation means for changing an operation function depending on whether the reproduced image is a moving image or a still image .
[0017]
In the invention according to claim 3, by changing the operation function depending on whether the reproduced image is a moving image or a still image , an operation suitable for each operation is performed regardless of whether the display image is a moving image or a still image. The function can be provided to the operator.
[0022]
[Form of the present invention]
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
(First embodiment)
FIG. 1 is a system configuration diagram of a medical image display apparatus 1 according to the first embodiment of the present invention.
In FIG. 1, a medical image display apparatus 1 is connected to an ultrasonic diagnostic apparatus 3 that scans an ultrasonic beam and draws a tomographic image (hereinafter simply referred to as an image). It is assumed that the ultrasonic diagnostic apparatus 3 has a VTR apparatus capable of external control for storing moving images.
[0023]
Further, the medical image display device 1 includes a CPU unit 5 that performs control and arithmetic processing of the device based on the control program and control data, a memory unit 7 that stores the control program and control data of the device, and a magnetic head on the magnetic disk. An HD unit 9 that reads and writes image data via the CPU, a display control unit 11 that exchanges image data between the CPU unit 5 and the VRAM unit 13 and performs display processing of the image data, and an image that can be displayed on the display unit 15 LAN control for controlling data communication between a VRAM (Video Random Access Memory) 13 that expands and stores the data, a display unit 15 that displays an image, and another terminal device via Ethernet 19 Control data between the MO drive 21 and the MO drive 21 for controlling the drive of the magneto-optical disk capable of writing and erasing still image data. SCSI I / F unit 23 for transferring data and image data, I / O unit 31 for controlling input / output with keyboard 25, mouse 27, FD drive 29 and other I / O devices, and ultrasonic diagnostic apparatus 3 The serial I / F unit 35 that controls serial communication with the remote controller 33 or the like based on the RS232C standard and the image output from the ultrasonic diagnostic apparatus 3 are collected in the internal RAM, while the edited image is An image collecting unit 37 that generates an image to be displayed on the ultrasonic monitor of the ultrasonic diagnostic apparatus 3, and a scan conversion process for displaying the image generated by the display control unit 11 on the ultrasonic monitor of the ultrasonic diagnostic apparatus 3 On the other hand, an image conversion combining unit 39 that combines the image signal subjected to the scan conversion processing and the output image signal from the image collecting unit 37, and an internal bus 41 are included.
[0024]
Next, an operation of adding a mark to an image will be described using the flowchart shown in FIG.
First, the operator selects an image using an input device such as a keyboard or a trackball of the ultrasonic diagnostic apparatus 3 and selects whether to reproduce a moving image, a still image, or a mixed image. Here, for example, it is assumed that an image to be reproduced is only a moving image, and a specific image among the moving images is stationary. In this case, the output image from the ultrasonic diagnostic apparatus 3 may be an ultrasonic image being captured. Further, it is assumed that the ultrasonic image being captured is displayed on the monitor of the ultrasonic diagnostic apparatus 3.
[0025]
In step S <b> 10, the image taken by the ultrasonic diagnostic apparatus 3 is stored in the internal RAM of the image collection unit 37.
Next, in step S20, it is determined whether or not an instruction to add a mark to the image is sent from the remote controller 33 in order to adopt it as a prowl cut. If an instruction to add a mark is sent, the process proceeds to step S30. If an instruction to add a mark is not sent, the process proceeds to step S50.
[0026]
Next, in step S30, since an instruction to add a mark is sent, the CPU unit 5 instructs to add a mark to, for example, the lower right part of the image stored in the internal RAM of the image collecting unit 37.
[0027]
Next, in step S40, the image to which the mark stored in the internal RAM of the image collection unit 37 is added is stored in the HD unit 9.
On the other hand, in step S50, since an instruction to add a mark has not been sent, the CPU unit 5 stores the image stored in the internal RAM of the image collecting unit 37 in the HD unit 9 as it is.
Next, in step S60, it is determined whether or not an end instruction has been sent from the remote controller 33 in order to end the creation of the plus cut. If an end instruction has been sent, the process ends. If no end instruction has been sent, the process returns to step S10 to repeat the process.
[0028]
Next, the operation of the medical image display apparatus 1 will be described using the diagram shown in FIG.
By completing the processing of steps S10 to S60, the HD unit 9 stores images A1 to A4, B1 to B4, and C1 to C4 for one heartbeat as shown in FIG. . Here, images to which marks (hereinafter referred to as *) are added are A2, A4, B3, and C1.
Next, only the image numbers A2, A4, B3, and C1 to which the mark (*) stored in the HD unit 9 is added are stored in the browse cut table of the memory unit 7 to create a browse cut.
[0029]
Next, the CPU unit 5 reads out the images corresponding to the numbers sequentially specified from the HD unit 9 based on the image numbers A2, A4, B3, and C1 stored in the browse cut table of the memory unit 7 and displays them. The data is stored in the VRAM 13 via the control unit 11. On the other hand, the display control unit 11 reads out the image data stored in the VRAM 13 and displays it on the display unit 15. In this way, as shown in FIG. 3B, an image obtained by connecting A2, A4, B3, and C1, that is, a browse cut image can be reproduced and displayed on the display unit 15, and only an arbitrary range image is displayed. The time to read the image will be shortened.
[0030]
If the image to be reproduced is composed only of moving images, an arbitrary partial range is selected. When selecting a partial range, if the moving image represents, for example, a heart rate, it is possible to select any one heart rate of the electrocardiogram, and it is possible to select an operation time without reading the heart rate image in the same image redundantly. And playback time can be shortened.
[0031]
(Second Embodiment)
The system configuration of the medical image display apparatus 1 shown in FIG. 1 is characterized in that an interruption key for inputting an operator's interruption instruction is added to the remote controller 33.
Next, the operation of the medical image display apparatus 1 will be described using the diagram shown in FIG.
Now, as shown in FIG. 4, it is assumed that an image (A) obtained by connecting A2, A4, B3, and C1, that is, a browse cut image is sequentially reproduced and displayed on the display unit 15.
[0032]
At this time, it is assumed that the operator has pressed the interrupt key (b) of the remote controller 33. Here, the CPU unit 5 interrupts the reproduction display of the series of browse cut images A2, A4, B3, and C1, while the interruption key (B) is pressed at the reproduction time of the image number A2. The moving images A2 to Ax to A2 for one heartbeat are reproduced. Next, as indicated by the arrow (d), the process proceeds to the reproduction display of the browse cut image A4, and thereafter, the sequential reproduction display (a) of the series of browse cut images A2, A4, B3, C1 is executed.
[0033]
It is also possible to select and input either the next image or the previous image from the remote controller 33, and then press the interrupt key (e). In this case, as shown in FIG. It is also possible to interrupt the reproduction of the current image number A4 and reproduce the moving images B3 to Bx to B3 for one heartbeat including the selected next image B3.
Further, when an image number or mark (*) is designated from the remote controller 33, the image number or mark (*) may be jumped to. If no mark (*) is designated, it is possible to jump to the head of the image number. Further, after the reproduction display is performed, the moving image loop reproduction (i) is automatically performed.
[0034]
(Third embodiment)
The system configuration of the medical image display apparatus 1 shown in FIG. 1 is characterized in that a touch panel for inputting an operator's operation is added to the display screen of the display unit 15. FIG. 5 is a diagram illustrating a display screen of the display unit 15 that reproduces and displays a moving image. In the figure, 56 is a moving image rewind button, 57 is a playback button, 58 is a stop button, 59 is a fast forward button, and 60 is a pause button.
Next, FIG. 6 is a diagram showing a display screen of the display unit 15 that reproduces and displays still images. In the figure, reference numeral 61 denotes that an operation function similar to that of a still image rewind button, playback button, stop button, fast forward button, or pause button can be performed by pressing an arrow or moving the button 62.
[0035]
As shown in FIG. 4, when a file containing browse cut images is stored in the HD unit 9, when the image to be reproduced and displayed is a moving image, the moving image is displayed on the display unit 15 as shown in FIG. On the other hand, when a still image is reproduced and displayed during the reproduction of the moving image, the still image is displayed on the display unit 15 as shown in FIG. 6, so that each of the displayed images is a moving image or a still image. An operation function suitable for the operation can be provided to the operator.
[0036]
(Fourth embodiment)
The system configuration of the medical image display apparatus 1 shown in FIG. 1 is characterized in that a related attribute table for storing related attributes between individual moving images and still images is added to the memory unit 7.
FIG. 7 is a diagram illustrating a state in which playback of a browse cut image in which a moving image (vertical line) and a still image (shaded) are mixed is controlled.
[0037]
In the figure, (a) represents a state in which a moving image is repeatedly reproduced. Here, when the interruption key 71 is pressed from the remote controller 33, the process proceeds to reproduction of a still image (b).
As described above, when the interrupt key 71 is pressed, the CPU unit 5 reads the related attribute from the related attribute table stored in the memory unit 7 and displays the still image (b) as the related attribute of the moving image (b). Thus, when the interrupt key 71 is pressed, it is possible to shift from the repeated playback state of the moving image (A) to the playback of the still image (B).
[0038]
(Fifth embodiment)
FIG. 8 is a diagram illustrating a display screen of the display unit 15 that reproduces and displays moving images and still images.
In the figure, the reduced still images (B) and (C) are displayed on the moving image (A). If there is no related image, a message indicating that there is no image related to the display position (c) of the display unit 15 is displayed.
Next, FIG. 9A shows the flow of moving images, and FIG. 9B shows the flow of still images, which are displayed on the moving image screen (A) and still image screen (B) shown in FIG. 8, respectively. Is done. Note that the flow of still images shown in FIG. 9B shows related images.
[0039]
When there is a related still image, for example, the display screen of the display unit 15 may be divided into left and right parts in the vertical direction, and a moving image may be displayed on one side and a still image displayed on the other side. When there are a plurality of still images, a display period is set and related still images are sequentially displayed. When there is a single related still image, each image is displayed until an interruption instruction is received.
As described above, the CPU unit 5 reads the related attribute of the moving image from the related attribute table stored in the memory unit 7 based on the image number of the moving image being reproduced shown in FIG. Here, when the related attribute of the moving image is stored in the related attribute table, the still image corresponding to the related attribute is played back as shown in FIG. Still images related to moving images can also be played back.
[0040]
In addition, a moving image and a still image can be displayed by one browsing reproduction, and when one of the moving images is displayed, a related still image is displayed, and an operator can quickly view a necessary still image. Can be improved.
In the above-described embodiment, the case where image selection is performed using images for one heartbeat has been described. However, the target range for image selection may be arbitrarily selected. What is necessary is just to comprise so that the desired image range may be designated and input.
[0041]
【The invention's effect】
As described above, according to the present invention, an arbitrary image of a moving image is selected, a plurality of selected images are edited as a series of browse cut images, and then the edited series of browse cut images are continuously displayed. Then, by reproducing on the display screen, it is possible to efficiently generate and reproduce a browse cut image obtained by connecting the images.
