An MRI apparatus is an apparatus that places a patient in a static magnetic field and generates an MRI image of internal information of the patient based on high-frequency pulses applied to the patient. An ultrasonic diagnostic apparatus transmits ultrasonic waves from an ultrasonic probe into a patient, generates echo signals based on reflected waves, and obtains desired ultrasonic image data by image processing. An X-ray diagnostic apparatus generates projection image data of a patient based on electrical signals based on X-rays detected by an X-ray detector by irradiating the patient with X-rays.

An X-ray CT apparatus irradiates a patient with X-rays and generates CT image data such as an axial tomography of the patient based on an electric signal based on the X-rays detected by an X-ray detector. Nuclear medicine diagnostic equipment utilizes the property that drugs (blood flow markers, tracers) containing radioisotopes (RI: Radio Isotope) are selectively incorporated into specific tissues and organs in the body, and are distributed in the body. Gamma rays emitted from the RI are detected by a gamma ray detector to generate nuclear medicine image data in which the dose distribution of gamma rays is imaged.

An example in which the medical image diagnostic apparatus is an MRI apparatus will be described below using embodiments.

FIG. 2 is a block diagram showing functions of the display control device 20. As shown in FIG.

The processing circuit 25 of the display control device 20 implements an acquisition function 251 and a display control function 252 by reading and executing a program stored in the memory 26 or directly incorporated in the processing circuit 25. . A case where the functions 251 and 252 function as software will be described below as an example. good too.

The display control device 20 causes the display 28 to display progress information indicating the progress of diagnosis of the patient. In the examination room of the MRI apparatus 10, when a certain patient (hereinafter referred to as the first patient) is being imaged, from the viewpoint of privacy protection, the next patient (hereinafter referred to as the second patient) is interviewed and the imaging plan registration operation is performed in a separate room. done. Since the operator of the display control device 20 leaves the examination room of the MRI apparatus 10, when registering or changing the imaging plan for the first patient using the display control device 20 in a separate room, the display control device With the small display 28 of 20, there is a problem that it is difficult to determine whether the imaging plan for the first patient or the second patient is being operated. Therefore, an acquisition function 251 and a display control function 252 are provided to solve such a problem.

The acquisition function 251 acquires from the memory 26 the determination elements for determining the progress information indicating the progress of the diagnosis of the desired patient, and obtains the progress information of the diagnosis of the desired patient based on the determination elements. Including the ability to get. For example, diagnosis progress information can include patient registration, medical interview, imaging plan registration, imaging plan change, and image confirmation. In addition, progress information is not limited to the case where these five items are included. For example, the progress information may further include other progresses other than these five progresses, or may be the case where any one of these five progresses is absent. In addition, patient registration and interview may be combined as one progress. Note that the acquisition function 251 is an example of acquisition means.

FIG. 3 is a table showing the relationship between progress information determination elements and progress information.

When the progress information includes patient registration, medical interview, imaging plan registration, imaging plan change, and image confirmation, the determination elements of the progress information are, for example, patient information registration, medical interview, as shown in FIG. These are result registration, imaging plan registration, imaging start, and image generation. Specifically, patient information registration means whether the patient information has been registered in the memory 26 (or a server (not shown) connected to the display control device 20 via the network N). means whether the medical interview result has been registered in the memory 26, "imaging plan registration" means whether the imaging plan has been registered in the memory 26, and "imaging start" means that the start of imaging has been received from the MRI apparatus 10. image generation means whether the image has been generated from the MRI apparatus 10 .

When the patient information is not registered in the memory 26 (or the server connected to the display control device 20 via the network N), the acquisition function 251 obtains the progress status "Patient progress A”, and the progress information is “patient registration”. If the patient information has been registered in the memory 26 but the medical interview results have not been registered in the memory 26, the acquisition function 251 determines that the progress status of the second patient in front of him in the separate room is "patient progress B". and determines that the progress information is "inquiry". If the medical interview result has been registered in the memory 26 but the imaging plan has not been registered in the memory 26, the acquisition function 251 determines that the progress status of the second patient in the separate room is "patient progress C". and determines that the progress information is "shooting plan registration".

On the other hand, if the imaging plan has already been registered in the memory 26, but the information about the start of imaging has not been received from the MRI apparatus 10, the acquisition function 251 determines that the first patient undergoing imaging has progress status "patient progress D". and determines that the progress information is "imaging plan change". When the information indicating the start of imaging has been received from the MRI apparatus 10 but the information indicating the completion of image generation has not been received from the MRI apparatus 10, the acquisition function 251 determines whether the first patient undergoing imaging has progress status "patient progress E , and it is determined that the progress information is "imaging plan change". When the image generation completion information has been received from the MRI apparatus 10, the acquisition function 251 determines that the progress status of the first patient being imaged is "patient progress F" and the progress information is "image confirmation". I judge.

Returning to the description of FIG. 2, the display control function 252 includes a function of controlling the color tone of the screen when the patient information of the patient is displayed on the screen of the display 28 based on the progress information acquired by the acquisition function 251. . A tone (color tone) means a tone of color according to the relationship between lightness and saturation among the three attributes of color. For example, when the progress information indicates that the progress information differs between the first patient and the second patient, the display control function 252 displays the screen color tone when displaying the patient information of the first patient and the patient information of the second patient. The display 28 is controlled so that the color tone of the screen is different from the color tone (the first color tone of the second patient and the second color tone of the first patient shown in FIG. 3). Note that the display control function 252 is an example of display control means.

Here, consider a case where the progress information includes patient registration, medical interview, imaging plan registration, imaging plan change, and image confirmation. The display control function 252 can change the color tone of the screen of the display 28 in accordance with the patient's progress information displayed on the screen.

For example, the display control function 252 can control the display 28 so that at least one of patient registration, interview, and imaging plan registration and at least one of imaging plan change and image confirmation are different in color tone. Specifically, the display control function 252 controls the display 28 so that the color tone for at least one of patient registration, interview, and imaging plan registration is brighter than the color tone for at least one of imaging plan change and image confirmation. (See FIGS. 5 and 6, which will be described later).

In this way, the display control function 252 controls the screen in the case of progress information such as patient registration, which is intended to be shown to the patient, so that it has a bright color tone in order to reduce the patient's anxiety. To control the screen in the case of progress information such as a change of an imaging plan intended to be operated by the operator for a long time so as to have a dark color tone.

Details of the functions 251 and 252 will be described with reference to FIGS. 4 to 6. FIG.

Next, the operation of the display control system 1, particularly the display control device 20 will be described.

FIG. 4 is a diagram showing the operation of the display control device 20 as a flowchart. In FIG. 4, numerals attached to "ST" indicate respective steps of the flow chart.

The memory 26 appropriately registers progress information indicating the progress of diagnosis for each patient according to the operator's input via the input interface 27 .

The acquisition function 251 acquires determination elements for determining desired progress information of the patient from the memory 26 (step ST1). The acquisition function 251 obtains and acquires the progress information of the diagnosis of the desired patient based on the determination factors acquired in step ST1 (step ST2). For example, the desired patient's progress information is obtained by determining which one of patient registration, medical interview, imaging plan registration, imaging plan change, and image confirmation shown in FIG.

The display control function 252 controls the color tone of the screen when the patient information of the desired patient is displayed on the screen of the display 28 based on the progress information acquired in step ST2 (steps ST3 to ST5). For example, the display control function 252 determines whether the desired patient's progress information acquired in step ST2 is medical interview or imaging plan registration (step ST3). In other words, the display control function 252 determines whether or not the desired patient's progress information acquired in step ST2 corresponds to progress intended to be shown to the patient on the screen.

If it is determined YES in step ST3, that is, if the progress information acquired in step ST2 is determined to be patient registration, medical interview, or imaging plan registration, the display control function 252 controls the screen of the display 28 to be the first color tone. The display 28 is controlled so that (step ST4). For example, the display control function 252 controls the display 28 so that the color tone of the screen of the display 28 becomes relatively bright.

On the other hand, if NO in step ST3, that is, if it is determined that the progress information acquired in step ST2 is not patient registration, questioning, or imaging plan registration for the purpose of showing the screen to the patient, the display control function 252 controls the display 28 so that the screen of the display 28 has the second color tone (step ST5). For example, the display control function 252 controls the display 28 so that the color tone of the screen of the display 28 becomes relatively dark.

5 and 6 are diagrams showing display examples of patient information. FIGS. 5A to 5C are diagrams showing display examples when the screen showing patient information is displayed in the first color tone, that is, in a relatively bright color tone. FIGS. 6A and 6B are diagrams showing display examples when the patient information screen is displayed in the second color tone, that is, in a relatively dark color tone. 5 and 6 show examples in which the display control device 20 is a tablet terminal.

FIG. 5A shows a display example of patient information when the progress status "patient progress A" shown in FIG. 3, that is, the diagnosis progress information is "patient registration". If the progress is "Patient Progress A", it is assumed that the operator will show the screen of the display 28 to the second patient. Therefore, the screen of the display 28 is controlled to be displayed in a bright color (first color tone).

FIG. 5B shows a display example of patient information when the progress status "patient progress B" shown in FIG. 3, that is, the diagnosis progress information is "interview". If the progress is "patient progress B", it is assumed that the operator will show the screen of the display 28 to the second patient. Therefore, the screen of the display 28 is controlled to be displayed in a bright color (first color tone) as in FIG. 5(A).

FIG. 5C shows a display example of patient information when the progress status "patient progress C" shown in FIG. 3, that is, the diagnosis progress information is "imaging plan registration". When the progress is "imaging plan registration", it is assumed that the operator shows the screen of the display 28 to the second patient. Therefore, the screen of the display 28 is controlled to be displayed in a bright color (first color tone) as in FIGS. 5A and 5B.

In this way, when displaying information about the second patient, that is, a patient in front of the operator in a separate room, the display control function 252 causes the screens of the display 28 to be shown in FIGS. light color. Therefore, the operator can use the display control device 20 to recognize that the information for the second patient in front of him is being manipulated.

FIG. 6A shows a display example of patient information when the progress status "patient progress D (or patient progress E)" shown in FIG. 3, that is, the diagnosis progress information is "imaging plan change". When the progress is "imaging plan change", it is not assumed that the operator will show the screen of the display 28 to the first patient. Therefore, the screen of the display 28 is controlled to be displayed in a dark color (second color tone), unlike FIGS. 5A to 5C. By using this screen, the operator can change the imaging plan for a patient who is not in front of him.

FIG. 6B shows a display example of patient information when the progress status "patient progress F" shown in FIG. 3, that is, the diagnosis progress information is "image confirmation". If the progress is "image confirmation", it is not assumed that the operator will show the screen of the display 28 to the first patient. Therefore, the screen of the display 28 is controlled to be displayed in a dark color (second color tone) as in FIG. 6(A). By using this screen, the operator can check the MRI image data of the patient who is not in front of him.

In this way, when displaying information about the first patient, that is, a patient who is being imaged and is not in front of the patient, the display control function 252 changes the screen of the display 28 as shown in FIGS. be darkened. Therefore, the operator can use the display control device 20 to recognize that the information for the first patient being imaged is being manipulated.

In the above description, the display control function 252 controls to switch the color tone of the screen of the display 28 in two stages, but it is not limited to this case. For example, the display control function 252 can also control to switch the color tone of the screen in three or more stages.

When the operator of the display control device 20 uses the display control device 20 in a separate room to register or change the imaging plan for the first patient, on the small screen of the display control device 20 (for example, a tablet or the like), the first patient, It was difficult to determine which imaging plan for the second patient was being operated. That is, on the small screen of the display control device 20, it was not possible to instantly recognize whether the imaging plan registration tab or the imaging plan change tab was selected.

However, according to the display control device 20 described above, even if a display control device 20 having a small screen (for example, a tablet or the like) is employed, the operator can easily perform the operation by changing the color tone of the screen according to the progress information. It is possible to instantly determine whether the patient inside is the first patient or the second patient, and the second patient in front of the operator can also easily visually recognize what the operator is doing.

(Modification)
As described above, the first patient can be the patient being imaged in the examination room and the second patient can be the patient in a separate room in front of the operator. That is, the first patient and the second patient can be different patients. However, it is not limited to that case. For example, the first patient and the second patient are the same patient, the first patient is related to imaging at a first time (e.g., past), and the second patient is related to imaging at a second time (e.g., current). can also

According to at least one embodiment described above, the operator of the display control device 20 can easily recognize the progress of diagnosis of the patient.

Note that the acquisition function 251 is an example of acquisition means. The display control function 252 is an example of display control means.
