Abstract

A method for collecting three-dimensional data of an object from a series of projection images recorded by a biplane C-arm system is provided. A cardiac activity is recorded. The cardiac frequency and a start cardiac phase are determined for calculating parameters of the C-arm planes. The C-arm planes are set with the parameters and data is acquired in the start cardiac phase. The C-arm planes are uniformly rotated at a same speed in a forward motion over an angular area and record data at different angular areas at different cardiac phases. Data is acquired in the start cardiac phase after termination of the forward motion. The C-arm planes are uniformly rotated at a same speed in a backward motion over an angular area and records data at different angular areas at different cardiac phases. The captured data are reconstructed after termination of the backward motion upon completed acquisition.
