Calibration method for an ultrasound probe assembly, ultrasound probe assembly, and ultrasound imaging system

An ultrasound probe assembly, comprising:

• an ultrasound probe;
• a driving apparatus;
• a grid plate;
• and
• at least one puncture needle;
• wherein the at least one puncture needle is configured to be inserted into at least one reference point on the grid plate,
• wherein the ultrasound probe is configured to acquire an ultrasound image comprising an image of the at least one puncture needle and a two-dimensional coordinate system, the two-dimensional coordinate system comprising at least one coordinate point corresponding to the at least one reference point, and
• wherein the driving apparatus is configured to drive the ultrasound probe to move so as to cause a deviation between the image of the at least one puncture needle and the at least one coordinate point to be less than or equal to a first preset value.

An ultrasound imaging system, comprising:

• a processor;
• a memory, configured to store instructions executable by the processor;
• and
• an ultrasound probe assembly, comprising an ultrasound probe, a driving apparatus, a grid plate, and at least one puncture needle, the at least one puncture needle being inserted into at least one reference point on the grid plate;
• wherein the processor is configured to execute the instructions to:
• obtain an ultrasound image comprising an image of the at least one puncture needle and a two-dimensional coordinate system, the two-dimensional coordinate system comprising at least one coordinate point corresponding to the at least one reference point;
• determine a deviation between the image of the at least one puncture needle and the at least one coordinate point;
• and
• control, based on the deviation being greater than a first preset value, the driving apparatus to drive the ultrasound probe to move so as to cause the deviation to be less than or equal to the first preset value.
