Image quality compensation for duplex or triplex mode ultrasound systems

Abstract

Duplex operation for ultrasound imaging uses a single fixed voltage level. Both B-mode and color-mode imaging are performed using a power level that may be less than the power level for single-mode B-mode imaging, and may be greater than the power level for single-mode color-mode imaging. A duty cycle of color-mode pulses may be reduced. To enhance image quality, the number of cycles in the B-mode pulse profile may be increased. To enhance image quality, the center frequency of the B-mode pulse profile may be reduced, and dynamic filtering for B-mode received pulses may be appropriately modified.

Description

technical field [0001] The present invention relates generally to ultrasound imaging, and more particularly to methods of ultrasound delivery that enable multiple imaging modalities. Background technique [0002] Usually, different imaging modes require different voltage levels to transmit appropriate instantaneous power levels, and different voltage levels require various voltage power supplies, which increases the complexity of the system. [0003] Ultrasound imaging systems produce a series of images depicting a part of the body. Ultrasound imaging has been widely used to observe tissue structures in the human body, such as the structure of the heart, organs in the abdomen, the fetus, and the vasculature. Typically, an ultrasound imaging system includes sensors for transmitting and receiving signals coupled to a beamforming device. The transmit beam forming device sends electrical pulses to the sensor within a predetermined time sequence to generate a transmit beam, whic...
