Abstract
Method and apparatus for increased accuracy of an image of object density pixel values obtained by forming linear combinations thereof. A measured variable M is related to an integration of the actual object density .rho. over space q by a transform function F, i.e., M(t)=.intg.F(t, q).rho.(q)dq, and an estimated object density .rho.* is obtained by an approximate inversion of the transform function, i.e., .rho.*(q)=.SIGMA.E(t,q)M(t), where the sum is over the samples taken. (In the case of magnetic resonance imaging, M is the magnetization induced in a coil transverse to the main magnetization coil, the transform function F(t,q) includes sinusoidal components, and the inversion function G includes an inverse Fourier transform.) Therefore, the estimated object density .rho.* is related to the actual object density .rho. by
