Patent ID: 8280130

Claim:
A method executable in a molecular imaging system for dynamic molecular imaging comprising dynamically estimating a first parameter (β(x)) and a second parameter (k(x)) of an activity function describing the bio-distribution of an administered tracer, the method comprising: specifying a first target variance (σ β,T (x)) and a second target variance (σ k,T (x)) of the first parameter (β(x)) and the second parameter (k(x)) of the activity function, respectively; initiating an image acquisition; reconstructing the first parameter (β(x)) and the second parameter (k(x)); reconstructing a first associated variance (σ β (x)) and a second associated variance (σ k (x)) of the first parameter (β(x)) and the second parameter (k(x)), respectively; and repeating the image acquisition and the reconstructing of the first parameter (β(x)) and the second parameter (k(x)) and the first associated variance (σ β (x)) and the second associated variance (σ k (x)) until the first associated variance (σ β (x)) and the second associated variance (σ k (x)) are equal to or less than the first target variance (σ β,T (x)) and the second target variance (σ k,T (x)), respectively.
