A new ultrasound imaging method: vibro-acoustography;

Study of vibro-acoustography with high spatial resolution based on sector array transducers

Influence of different transmission medium on the resolution,especially axial resolution,of a vibro-acoustography system is theoretically studied by introducing the point spread function(PSF) and axial response function(ARF) based on the basic principle of vibro-acoustography and a typical confocal transducer,which is made from dividing a concave focusing transducer into two concentric parts.

Objective To investigate the value of MRI and magnetic resonance angiography(MRA) for moyamoya disease .

Objective Vibration response imaging(VRI) is a new lung sound imaging technology.

Objective To explore the characteristics of vibration response imaging(VRI) in chronic obstructive pulmonary disease(COPD).

The development and analysis of target detection research based on polarization imaging technology

The experimental setup for polarization imaging based on dual-rotating-retarder technique is modified,and a method to obtain two images encoded by polarization degree and intensity with a single measurement process is proposed.

Aiming at detecting platform limited by the cubage,the idea that using CMOS detector to construct subminiature polarization imaging remote sensor is put forward,and its feasibility is analyzed.
