Abstract
Provided is a tomographic image displaying method and apparatus capable of displaying a plurality of tomographic images in an easily viewable manner and enabling viewers to immediately understand a region of interest or the like. A predetermined target tomographic image is specified among a plurality of tomographic images, a weighting factor is multiplied to each of the plurality of tomographic images, and the weighted tomographic images are added to thereby generate and display a combined tomographic image. The weighting factor multiplied to the specified target tomographic image is set so as to be larger than the weighting factors multiplied to at least one of the tomographic images other than the target tomographic image.
Claims15
A tomographic image displaying method comprising:
- irradiating a subject with radioactive rays from a plurality of different radiographing directions;
- acquiring a radiological image for each of the radiographing directions, detected by a radiological image detector with the irradiation of radioactive rays;
- generating a plurality of tomographic images of the subject based on a plurality of acquired radiological images;
- and
- displaying the plurality of generated tomographic images, the method further comprising:
- specifying a predetermined target tomographic image among the plurality of tomographic images;
- multiplying a weighting factor to each of the plurality of tomographic images and adding the plurality of tomographic images multiplied by the weighting factors to thereby generate a combined tomographic image;
- and
- displaying the generated combined tomographic image,
- wherein a weighting factor multiplied to the specified target tomographic image is set so as to be larger than a weighting factor multiplied to at least one tomographic image other than the target tomographic image.
A tomographic image displaying apparatus comprising:
- a radiological image acquisition unit that irradiates a subject with radioactive rays from a plurality of different radiographing directions to acquire a radiological image for each of the radiographing directions, detected by a radiological image detector with the irradiation of radioactive rays;
- a tomographic image generation unit that generates a plurality of tomographic images of the subject based on a plurality of radiological images acquired by the radiological image acquisition unit;
- and
- a display unit that displays the plurality of tomographic images generated by the tomographic image generation unit, the apparatus further comprising:
- a combined tomographic image generation unit that multiplies a weighting factor to each of the plurality of tomographic images generated by the tomographic image generation unit and adds the plurality of tomographic images multiplied by the weighting factors to thereby generate a combined tomographic image;
- and
- a target tomographic image specifying unit that specifies a predetermined target tomographic image among the plurality of tomographic images,
- wherein the combined tomographic image generation unit sets a weighting factor of the target tomographic image specified by the target tomographic image specifying unit so as to be larger than a weighting factor of at least one tomographic image other than the target tomographic image, and
- wherein the display unit displays the combined tomographic image generated by the combined tomographic image generation unit.
