[0005]
[Problems to be solved by the invention]
However, in the medical image diagnostic system as described above, when a lesion is detected in an examination image, a recognition assist function such as marker display operates on all the lesions on the detected examination image, which hinders diagnosis. The use of digitized image data is not sufficient.
[0006]
In view of the above circumstances, an object of the present invention is to provide a method of using a medical image diagnostic terminal in which digitized image data is further used in diagnosis of an inspection image.
[0007]
[Means for Solving the Problems]
Among the methods for using the medical image diagnostic terminal of the present invention to achieve the above object, the first method for using the medical image diagnostic terminal is:
Use via a network connected to a diagnostic image capturing apparatus for generating a medical image of a patient and an image server apparatus having an image database for storing medical images generated by the diagnostic image capturing apparatus In a method of using a medical diagnostic imaging terminal that provides medical images to a person,
Enter the inspection purpose and input
A medical image is displayed with a lesion marker that identifies the lesion portion of the lesion portion in the medical image that matches the purpose of the examination input as specified.
[0008]
In the medical image diagnostic terminal according to the method of using the first medical image diagnostic terminal of the present invention, a lesion that matches the input examination purpose is displayed with a marker. Therefore, for example, when there are two types of examinations, namely, a health examination that is confirmation of the presence or absence of a disease and a detailed examination that is a detailed confirmation of a site where there is a disease, the health examination is selected as the examination purpose. When a lesion is detected, no marker is attached to the other examination items in the medical examination for which the lesion is not supported, and a close examination is selected for the examination purpose. A mode in which markers are attached to all detected lesions can be adopted. That is, according to the medical image diagnostic terminal according to the method of using the first medical image diagnostic terminal of the present invention, the display mode of the inspection image can be changed according to the inspection purpose using the digitized image data.
[0009]
Here, when displaying a medical image, a lesion marker having a size that matches the purpose of the inspection among lesion sites in the medical image may be displayed.
[0010]
As described above, the marker may not be attached, but may be determined based on a different lesion size depending on the examination purpose.
[0011]
Of the methods of using the medical image diagnostic terminal of the present invention for achieving the above object, the second method of using the medical image diagnostic terminal is:
A user connected via a network to a diagnostic image capturing apparatus for generating a medical image of a patient and an image server apparatus having an image database for storing the medical image generated by the diagnostic image capturing apparatus In a method of using a medical diagnostic imaging terminal that provides a medical image for

To do.
[0012]
In the medical image diagnostic terminal according to the second method of using the medical image diagnostic terminal of the present invention, the examination image is displayed together with the occurrence time of the lesion detected from the examination image or the elapsed time since the occurrence of the lesion. In other words, according to the medical image diagnostic terminal according to the second method of using the medical image diagnostic terminal of the present invention, by using the digitized image data, the elapsed period from the occurrence of the lesion that can be determined by uniform judgment is obtained. Since the display is performed, the lack of experience or knowledge on the side of viewing the inspection image can be compensated.
[0013]
Here, in determining the elapsed period from the occurrence of the lesion, the elapsed period or generation time may be determined based on the size of the lesion.
[0014]
