Abstract
According to the method and the apparatus for acquiring a CBCT image based on adaptive sampling according to the exemplary embodiment of the present disclosure, a final CBCT image is acquired by reconstructing a plurality of cone beam computed tomography (CBCT) images acquired based on adaptive sampling so that a dose applied to the target patient may be reduced.
Claims11
A CBCT image acquiring method based on adaptive sampling, comprising:
- a step of acquiring a plurality of image scanning points based on a previously acquired medical image for a target patient, by acquiring an image for every image scanning point based on the medical image, sorting images for image scanning points based on a quantitative value for each of images for image scanning points, selecting a plurality of images according to a predetermined criterion, among sorted images for image scanning points, and acquiring the image scanning points corresponding to the plurality of selected images as the plurality of image scanning points;
- a step of acquiring a plurality of cone beam computed tomography (CBCT) images for the target patient based on the plurality of image scanning points;
- and
- a step of acquiring a final CBCT image for the target patient based on the plurality of CBCT images.
A CBCT image acquiring apparatus which reconstructs a plurality of cone beam computed tomography images acquired based on adaptive sampling to acquire a final CBCT image, the apparatus comprising:
- a memory which stores one or more programs to acquire the final CBCT image by reconstructing the plurality of CBCT images acquired based on adaptive sampling;
- and
- a processor which performs an operation for reconstructing the plurality of CBCT images acquired based on adaptive sampling according to one or more programs stored in the memory to acquire the final CBCT image,
- wherein the processor acquires a plurality of image scanning points based on a previously acquired medical image for a target patient, acquires the plurality of CBCT images for the target patient based on the plurality of image scanning points, and acquires a final CBCT image for the target patient based on the plurality of CBCT images, and
- wherein the processor acquires an image for every image scanning point based on the medical image, sorts images for image scanning points based on a quantitative value for each of images for image scanning points, selects a plurality of images according to a predetermined criterion, among sorted images for image scanning points, and acquires the image scanning points corresponding to the plurality of selected images as the plurality of image scanning points.
