Methods 21 cases with PE(embolus consisting of tumor in 1 case) were examined with MSCT pulmonary angiography,the reformation images consisted of 10 mm slices,with 10 mm reconstruction intervals and 1.

Objective To study the diagnostic value of multi-slice spiral CT pulmonary angiography(MSCTPA) for pulmonary embolism(PE).

Objective To study the diagnostic value of spiral CT pulmonary angiography(SCTPA) for pulmonary embolism(PE).

Improvement in lateral resolution of mono-pulse 3-D imaging radar using RELAX algorithm;

The principle of mono-pulse 3-D imaging is introduced and the effects of target angle movement on the imaging are analyzed in this paper.

3-D imaging by a 2-D ultrasonic phased array;

Microwave 3-D imaging echo simulation for discrete targets;

Analysis and compensation of mismatching between two ISAR images in interferometric inverse synthetic aperture radar 3-D imaging;

Clinical value of three-dimensional imaging of complex renal calculi with CT data for the access of percutaneous nephrolithotomy

A mathematical model of three-dimensional imaging has been built and proved according to the physiological features of visual organs in three-dimensional imaging,the optical property of lenticular screen and the relative coordinate of both eyes.

The model of the interferometric inverse synthetic aperture radar(InISAR) three-dimensional imaging is proposed when the angle between the target and the antenna axis is relatively large.
