Abstract

A diagnosis support system which performs computer processing of data obtained from an object to be examined and presents the obtained diagnostic information is disclosed. The diagnosis support apparatus includes a diagnosis support processing unit which processes data obtained from the object to extract diagnosis support information, a storage unit which stores the examination history of the object, and a changing unit which changes a processing method in the diagnosis support processing unit in accordance with the examination history of the object stored in the storage unit. In at least one embodiment, diagnosis processing is executed to obtain medical diagnostic information by performing computer processing of data obtained from the object, and the processing method for diagnosis support processing is changed in accordance with the examination history of the object.

First claim

The invention claimed is:

1. A diagnosis support apparatus operably coupled to a medical examination data acquisition apparatus, the diagnosis support apparatus comprising:
a processor; and
a memory having stored thereon instructions which, when executed by the processor, cause the processor to:
obtain elapsed time from a previous examination based on an examination history of an object;
narrow a size range for detecting a lesion in accordance with the elapsed time, the size range representing a size of the lesion to be detected; and
detect the lesion included in an image of the object in accordance with the narrowed size range.

2. The diagnosis support apparatus according to claim 1 , wherein the instructions further cause the processor to:
narrow the size range in accordance with the elapsed time and a size of the lesion which was detected in the previous examination.

3. A diagnosis support apparatus operably coupled to a medical examination data acquisition apparatus, the diagnosis support apparatus comprising:
a processor; and
a memory having stored thereon instructions which, when executed by the processor, cause the processor to:
obtain an examination history of an object;
narrow a size range for detecting a lesion in accordance with the examination history of the object, the size range representing a size of the lesion to be detected;
calculate an onset probability of the lesion in accordance with the examination history of the object;
narrow a size range for detecting a lesion in accordance with the onset probability; and
detect the lesion included in an image of the object in accordance with the narrowed size range.

4. A control method of a diagnosis support apparatus operably coupled to a medical examination data acquisition apparatus, the method comprising:
obtaining elapsed time from a previous examination based on an examination history of an object;
narrowing a size range for detecting a lesion in accordance with the elapsed time, the size range representing a size of the lesion to be detected; and
detecting the lesion included in an image of the object in accordance with the narrowed size range.

5. A non-transitory computer readable storage medium storing a program for causing a computer to execute a control method of a diagnosis support apparatus operably coupled to a medical examination data acquisition apparatus, the method comprising:
obtaining elapsed time from a previous examination based on an examination history of an object;
narrowing a size range for detecting a lesion in accordance with the elapsed time, the size range representing a size of the lesion to be detected; and
detecting the lesion included in an image of the object in accordance with the narrowed size range.

6. The diagnosis support apparatus according to claim 2 , wherein the instructions further cause the processor to:
predict a size of the lesion based on the elapsed time and the size of the lesion which was detected in the previous examination, and
narrow the size range in accordance with the predicted size of the lesion, the narrowed size range including the predicted size.
