Abstract
A display control apparatus that performs rendering on volume data generated based on a signal obtained by receiving a photoacoustic wave generated by an object irradiated with light includes a first unit configured to obtain positional information of a surface of the object, a second unit configured to set a region inside the object between a surface located at a first distance from the surface of the object and a surface located at a second distance from the surface of the object as a display region on the basis of the positional information of the surface of the object, and a third unit configured to perform the rendering on the volume data in a manner that the display region and a region except for the display region can be discriminated from each other.
Claims11
A display control apparatus that performs rendering of volume data generated based on a signal obtained by receiving a photoacoustic wave generated by an object irradiated with light, the display control apparatus comprising:
- a first unit configured to obtain positional information of a first surface of the object;
- a second unit configured to set a display region inside the object between a second surface located at a first distance from the first surface of the object and a third surface located at a second distance from the first surface of the object, and set a surface vicinity region located from the first surface of the object to the second surface located at the first distance and set a deep region away from the third surface located at the second distance based on the first surface of the object;
- and
- a third unit configured to perform the rendering of the volume data in a manner that the display region is more emphasized than the surface vicinity region and the deep region,
- wherein the third unit performs the rendering of the volume data in a manner that an opacity of the display region is automatically set to be higher than an opacity of the surface vicinity region and the deep region, or a transparency of the display region is automatically set to be lower than a transparency of the surface vicinity region and the deep region, and
- wherein the third unit causes a display unit to display information about the first distance and information about the second distance together with an image on which rendering of volume has been performed.
A display method of performing rendering of volume data generated based on a signal obtained by receiving a photoacoustic wave generated by an object irradiated with light, the display method comprising:
- obtaining positional information of a first surface of the object;
- setting a display region inside the object between a second surface located at a first distance from the first surface of the object and a third surface located at a second distance from the first surface of the object, and set a surface vicinity region located from the first surface of the object to the second surface located at the first distance and set a deep region away from the third surface located at the second distance based on the first surface of the subject;
- and
- performing the rendering of the volume data in a manner that the display region is more emphasized than the surface vicinity region and the deep region,
- wherein the third unit performs the rendering of the volume data in a manner that an opacity of the display region is automatically set to be higher than an opacity of the surface vicinity region and the deep region, or a transparency of the display region is automatically set to be lower than a transparency of the surface vicinity region and the deep region, and
- wherein the third unit causes a display unit to display information about the first distance and information about the second distance together with an image on which rendering of the volume data has been performed.
