Diagnosis support apparatus and X-ray CT apparatus
In one embodiment, a diagnosis support apparatus includes: an input circuit configured to acquire a first medical image; and processing circuitry configured to generate a second medical image from the first medical image in such a manner that information included in the second medical image is reduced from information included in the first medical image, extract auxiliary information from the first medical image, and perform inference of a disease by using the second medical image and the auxiliary information.
1. A diagnosis support apparatus comprising:
an input circuit configured to acquire a first medical image obtained by imaging an object; and
processing circuitry configured to
generate a second medical image from the first medical image in such a manner that information included in the second medical image is reduced from information included in the first medical image,
extract auxiliary information from the first medical image,
input the second medical image and the auxiliary information into a trained model generated through machine learning, and cause the trained model to infer a disease information about the object, based on the second medical image and the auxiliary information, and
wherein the processing circuitry is configured to extract a bone-removed image from the first medical image as the auxiliary information by performing bone removal processing on the first medical image.
2. The diagnosis support apparatus according to claim 1 , wherein:
the first medical image is a three-dimensional volume image; and
the second medical image is a two-dimensional virtual projection image generated from the three-dimensional volume image.
3. The diagnosis support apparatus according to claim 1 , wherein:
the first medical image is a three-dimensional volume image; and
the second medical image has a lower resolution than the three-dimensional volume image.
4. The diagnosis support apparatus according to claim 1 , wherein the processing circuitry is configured to extract information on an anatomical feature point from the first medical image as the auxiliary information by performing processing of detecting the anatomical feature point on the first medical image.
5. The diagnosis support apparatus according to claim 1 , further comprising a display, wherein:
the first medical image is a three-dimensional volume image; and
the processing circuitry is configured to cause the display to display a two-dimensional image on which information on inference result of the disease is superimposed.
