Title: Method and device for calculating projection image
Inventor: YOSHITOME EIJI
IPC: G06T15/08
Filed: 1993-08-18
Abstract: PURPOSE:To reduce the calculation quantity of projection values and shorten the process time as compared with the calculation of projection values of all pixels constituting the projection image by substituting projection values of pixels corresponding to another projection image, which is already calculated, for projection values of some of the pixels. CONSTITUTION:Scan data gathered from a patient K by a medical image diagnostic device M such as CT and MRI are passed to the computer 2 of the projection image calculation device 100. The three-dimensional model structure part 2a of the computer 2 structures a three-dimensional model 3 by using the scan data. A parameter setting part 2b receives a projection initial angle thetas, a projection final angle thetae, a projection interval angle alpha, and an angle K of rotation as parameters from a user through a console 4. Further, a thinning- out quantity (n) and a threshold value delta are received. A projecting direction rotation part 2c calculates a projection direction theta(m) at each thinning-out projection interval angle nalpha from the projection initial angle thetas to the projection final angle thetae. Then calculated directions are supplied to an unconditional projection image acquisition part 2e in order.
