A method, system, and program enabling a variable varying with animal's motions such as a joint torque to be accurately measured in a series of the animal's motions. First, a reference relational expression representing a relation between myoelectric potentials and a knee joint torque is set on the basis of the myoelectric potentials and the knee joint torque (variable) measured by using an inverse dynamics model. Then, the knee joint torque is measured on the basis of the measured myoelectric potentials and according to the reference relational expression. For example, if an animal makes first and second motions continuously, first a reference relational expression is set on the basis of myoelectric potentials measured in the first motion and a knee joint torque corresponding to the first motion. Then, a knee joint torque corresponding to the second motion is measured on the basis of the myoelectric potentials measured in the second motion and according to the reference relational expression. The first and second motions are arbitrary and the animal is not forced to make a given motion.

Image quality deterioration due to a drop in resolution or lowering of S / N ratio while reducing the amount of data stored during a 3D data acquisition process, and shortening the time from the start of an examination to the end of imaging. The method and apparatus of this invention perform, in parallel with the 3D data acquisition process, addition of sinograms, reading of subsets of the sinograms having been added, and image reconstruction. Consequently, the amount of data stored is reduced, and the time from the start of an examination to the end of imaging is shortened. At the same time, since 3D iterative reconstruction is not accompanied by conversion from 3D data to 2D data, a drop in resolution due to errors occurring with the conversion from 3D data to 2D data is avoided. The 3D iterative reconstruction can directly incorporate processes such as an attenuation correction process. It is thus possible to avoid also a lowering of S / N ratio resulting from an indirect incorporation of such processes.
