Abstract
An interlaced data acquisition scheme is employed in an ultrasound imaging device to reduce the amount of electrical power consumed by the device's transmit firings when collecting video data. Reducing electrical consumption according to the present disclosure reduces battery size, weight and cost; reduces heat generation; reduces need for heat-dissipating materials in the probe and prolongs probe uptime. A reconstruction algorithm is employed to produce images from the interlaced data that are comparable in quality to videos that would be obtained by a conventional (non-interlaced) image acquisition.
