Abstract
The present disclosure provides a system and method for image generation. The method may include obtaining a first image of a first modality representing a first region of a subject. The method may further include determining a second image of a second modality representing a second region of the subject based on the first image. The second region may include at least part of the first region of the subject. A slice direction of the first image may be the same as a slice direction of the second image. The method may further include generating a fused image by fusing the first image and the second image.
Claims13
A system, comprising:
- at least one storage device storing executable instructions, and
- at least one processor in communication with the at least one storage device, when executing the executable instructions, causing the system to perform operations including:
- obtaining a first image of a first modality representing a first region of the subject, wherein the first image includes a functional image indicative of a distribution of a metabolite in the first region, the first image includes a magnetic resonance spectroscopy (MRS) image;
- generating a pseudocolor image based on the first image, wherein the pseudocolor image includes a plurality of pixels each of which corresponds to a pixel of the first image, each of the pixels in the pseudocolor image has a color that demonstrates the concentration value of a metabolite at a portion or position of the subject, and the color serves as an index or code of the pixel, in which the index or code points to an entry of a color look-up table (CLUT);
- obtaining a second image by processing pixel values of pixels in an additional image using an interpolation function, the interpolation function including one or more coefficients associated with a deviation between slice information of the first image and slice information of the additional image, the additional image including a structural image indicative of one or more structural characteristics of a second region, the second image representing the second region of the subject, the second region including at least part of the first region of the subject, a slice direction of the additional image failing to match a slice direction of the first image, the slice direction of the first image being same as a slice direction of the second image;
- and
- generating a fused image by fusing the pseudocolor image and the second image, wherein the fused image includes a fusion of the second image and the distribution of the metabolite indicated by the first image.
