| titleOfInvention | METHOD IMAGING FAT DISTRIBUTION WITH CT EQUIPMENT |
| abstract | An object of the present invention is to generate an image showing the distribution of fat based on the composition ratio of fat in tissue from cross-sectional image data by X-rays.n n n The steps of the present invention are as follows (refer to FIG. 1), by using a phantom loaded with a fat reference substance in addition to the osteoarthritis equivalent substance, scanning is performed on the subject and the phantom at different tube voltages to obtain two cross-sectional image data. (D1, D7).n n n The CT value of each pixel in the entire area or the target area of the cross-sectional image data is detected as [CT value of tissue containing fat] awf. (D2, D8), CT value of an osteoarthritis equivalent substance is detected, and CT value Calculate the rare linear line of the density of the osteoarthritis equivalent, and set the CT value to [CT value of tissue not containing fat] anf (D3, D9), and detect [CT value of fat reference substance] aff (D4, D10), the CT value of the blood portion is detected as [CT value of soft tissue reference substance] ast (D5, D11), and each CT value is represented by αwf = αnf + β (αff-αst) using β fat percentage parameter. (A)). (D6, D12) In view of the fact that the bone salt equivalent density is invariant with the scan at different tube voltages, the rare straight line and the entire area or the target area of the cross-sectional image data from equation (A) The fat fraction parameter β of each pixel is calculated (D13), and an image based on the fat fraction parameter β is generated (D14). |
