Abstract
A volume rendering image is obtained based on a 3D MRI image by automatically performing appropriate opacity setting. A three-dimensional image of a subject is received, a distribution of pixel values of the three-dimensional image is calculated, a pixel value of a predetermined feature amount is calculated based on the distribution of the pixel values, and opacity is set for each of the pixel value included in the three-dimensional image based on the pixel value of the feature amount. Accordingly, the opacity can be set automatically. The volume rendering image of the three-dimensional image is generated using the opacity.
Claims15
A magnetic resonance imaging apparatus comprising:
- a static magnetic field generation unit configured to generate a static magnetic field in a space in which a portion to be imaged of a subject is disposed;
- a measurement control unit configured to apply a gradient magnetic field and a high frequency magnetic field to the subject and to detect a nuclear magnetic resonance signal generated from the portion to be imaged;
- and
- an arithmetic processing unit configured to reconstruct a three-dimensional image of the subject using the detected nuclear magnetic resonance signal, wherein
- the arithmetic processing unit obtains a distribution of pixel values of the three-dimensional image, calculates a pixel value of a predetermined feature amount based on the distribution of the pixel values, and sets opacity for each of the pixel values included in the three-dimensional image based on the pixel value of the feature amount.
An image processing apparatus comprising:
- an arithmetic processing unit configured to receive a three-dimensional image of a subject and perform arithmetic processing thereon, wherein
- the arithmetic processing unit obtains a distribution of pixel values of the three-dimensional image, calculates a pixel value of a predetermined feature amount based on the distribution of the pixel values, and sets opacity for each of the pixel values included in the three-dimensional image based on the pixel value of the feature amount.
An image processing method comprising:
- receiving a three-dimensional image of a subject;
- obtaining a distribution of pixel values of the three-dimensional image;
- calculating a pixel value of a predetermined feature amount based on the distribution of the pixel values;
- setting opacity for each of the pixel values included in the three-dimensional image based on the pixel value of the feature amount;
- and
