In discrete detector PET, natural pixels are image basis functions calculated from responses of detector pairs. By using reconstruction with natural pixels the discretization of the object into a predefined grid can be avoided. Instead of trying to find the object x from system matrix A and measured data p by solving Ax = p, one solves Mq = AA/sup T/q = p. The backprojection of the final q results in the estimated image of the object x. In previous work natural pixels were calculated by… CONTINUE READING
