Three-dimensional image display apparatus, method, and program

摘要

A label adding unit adds labels to structures such as a body surface region, a lung region, bronchi, and pulmonary nodules of a human extracted by a structure extraction unit from a three-dimensional image of a chest. An image display control unit displays the three-dimensional image by volume rendering on a display unit. At this time, a label display determination unit determines at least one label to be displayed with the volume rendering image to be displayed based on the opacity during the volume rendering display. A label display control unit displays the determined label with the volume rendering image on the display unit.

主权项

1. A three-dimensional image display apparatus that displays a three-dimensional image of an object composed of a plurality of structures, to each of which at least one label is added, comprising;
an image display control unit that emits a virtual light beam from a projection plane toward the three-dimensional image, generates a three-dimensional image by virtual reflected light from the interior of the object, based on the colors (R, G, B) and opacity corresponding to the respective signal values in the three-dimensional image, and generates a projection image, which enables seeing through a three-dimensional structure in the interior of the object, on the projection plane from the three-dimensional image to display the three-dimensional image by volume rendering; a label display determination unit that determines at least one label to be displayed from a plurality of labels based on the opacity of the three-dimensional image to be displayed by volume rendering; a label display control unit that adds the at least one label determined to be displayed to a corresponding structure and displays the label with the three-dimensional image to be displayed by volume rendering.
