1. Field
Exemplary embodiments of the present disclosure relate to an apparatus and method for generating a medical image to realistically display an object or inner tissues of the object.
2. Description of the Related Art
Research into medical imaging apparatuses is actively being conducted to go along with an increasing interest in improving the health of people. Examples of medical imaging apparatuses may include an X-ray imaging apparatus, an X-ray fluoroscopy apparatus, a computerized tomography (CT) scanner, a magnetic resonance imaging (MRI) apparatus, a positron emission tomography (PET) apparatus, and an ultrasonic diagnostic apparatus.
These medical imaging apparatuses display a 2D or 3D medical image of an object. A 2D medical image refers to a sectional image of inner tissues of an object. A 3D medical image refers to an image acquired through volume rendering of 3D volume data generated based on a plurality of sectional images.
The 2D and 3D medical images may be grayscale images or color images. Grayscale images are limited in the ability to provide a realistic image of an object, and thus, color images are currently the norm. Such color images may be acquired by mapping a grayscale image with colors that are similar to those of inner tissues of an object.
However, colors used in mapping are arbitrarily selected and thus, there remain limitations in providing a more realistic color image.
