Breast cancer diagnosis device

A breast cancer diagnosis device comprising:

• an X-ray diagnosis unit generating an X-ray transmission image of a diagnosis subject;
• an optical diagnosis unit generating an optical transmission image of the diagnosis subject;
• compression pads pressing and fixing upper and lower portions of the diagnosis subject at a predetermined pressure so that the X-ray diagnosis unit and the optical diagnosis unit sequentially generate the X-ray image and the optical transmission image while the compression pads fix the diagnosis subject;
• a transfer unit which is coupled to the X-ray diagnosis unit and the optical diagnosis unit to transfer all or part of the X-ray diagnosis unit and the optical diagnosis unit, and sequentially transfer all or part of the X-ray diagnosis unit or the optical diagnosis unit toward the diagnosis subject;
• and
• a lesion determination unit for fusing the optical transmission image and the X-ray transmission image, which are sequentially photographed in a state in which the diagnosis subject is constantly fixed to generate a fusion image,
• wherein the X-ray diagnosis unit comprises:
• an X-ray irradiation unit generating X-rays to irradiate the X-rays onto the diagnosis subject;
• and
• an X-ray detection unit disposed to face the X-ray irradiation unit to acquire an X-ray diagnosis image of the diagnosis subject from the X-rays, which are irradiated from the X-ray irradiation unit to pass through the diagnosis subject,
• wherein the optical diagnosis unit comprises:
• an optical irradiation unit irradiating light onto the diagnosis subject;
• and
• an optical detection unit disposed to face the optical irradiation unit to acquire an optical diagnosis image of the diagnosis subject from the light, which is irradiated from the optical irradiation unit to pass through the diagnosis subject,
• wherein the transfer unit comprises a horizontal transfer unit coupled to the X-ray detection unit and the optical detection unit to horizontally transfer the X-ray detection unit and the optical detection unit, and the transfer unit moves the X-ray detection unit and the optical detection unit to sequentially place the X-ray detection unit and the optical detection unit in a straight line with the diagnosis subject while the compression pads fix the diagnosis subject,
• wherein the lesion determination unit generating a first three-dimensional image in a digital breast tomosynthesis (DBT) manner by synthesizing the X-ray transmission image in a filtered back projection (FBP) manner, generating a second three-dimensional image in a diffuse optical tomography (DOT) manner based on the optical transmission image, and determining whether one or more lesions exist in the diagnosis subject using the first three-dimensional image and the second three-dimensional image.
