Angiographic investigation method of organ of patient, involves changing resolution such that large volume data acquisition takes place in low resolution and small volume data acquisition in high resolution
Angiographic investigation method of organ of patient, involves changing resolution such that large volume data acquisition takes place in low resolution and small volume data acquisition in high resolution
The method involves reconstructing data acquisition of angiography system by using three-dimensional rotational angiography of an investigation object. An aperture of collimator is changed, during the data acquisition for acquisition of a large volume of object in large opening of collimator and a small volume in small aperture of collimator. The resolution is changed such that large volume data acquisition takes place in low resolution and small volume in high resolution. The three-dimensional volume of investigation object is reconstructed from detected data, and played back.
