1. A method of adjusting for motion sensor drift during ultrasound imaging with an ultrasound imaging system, the ultrasound imaging system comprising:
a probe including at least one transducer element; a motion sensing system attached to the probe, the motion sensing system comprising an accelerometer or a gyro sensor; a position sensing system associated with the probe, where the position sensing system is different from the motion sensing system; a display device; and a processor in communication with the probe and the display device, the method comprising:
controlling the probe with the processor to acquire a plurality of frames of ultrasound data;acquiring probe motion data with the motion sensing system during the process of controlling the probe with the processor to acquire the plurality of frames of ultrasound data;receiving, with the processor, probe motion data from the motion sensing system;receiving, with the processor, probe position data from the position sensing system;detecting, with the processor, when the probe is stationary based on the probe position data;calculating, with the processor, a drift compensation for the probe motion data using the probe motion data and the probe position data, where the drift compensation comprises an adjustment to compensate for an amount of drift in the motion sensing system;applying the drift compensation to the probe motion data to generate compensated probe motion data;generating, with the processor, composite ultrasound data by combining at least two of the plurality of frames of ultrasound data based on the compensated probe motion data; anddisplaying an image generated from the composite ultrasound data on the display device. |
