1. A needle guide system, comprising:
a puncture device;
an ultrasound transducer, configured to obtain an ultrasound image;
a first orientation detector, disposed on the puncture device;
a second orientation detector, disposed on the ultrasound transducer;
a proximity detector, disposed on at least one of the puncture device and the ultrasound transducer and configured to obtain a relative distance between the puncture device and the ultrasound transducer; and
a processor, coupled to the ultrasound transducer, the first orientation detector, the second orientation detector, and the proximity detector, and configured to:
obtain a spatial relationship between the puncture device and the ultrasound transducer by using the first orientation detector, the second orientation detector, and the proximity detector, comprising:
obtaining a first orientation from the first orientation detector and a second orientation from the second orientation detector; and
calculating a position of inserting the puncture device relative to the ultrasound probe on a body surface by using the relative distance; and
predict a needle trajectory of the puncture device in the ultrasound image based on the first orientation, the second orientation and the position of inserting the puncture device on the body surface.
