Final answer:
Contrast echocardiography is a technique used to enhance the visibility of the heart and blood vessels during an echocardiogram. Instrument settings can be adjusted to optimize the contrast images, such as increasing the gain and adjusting the time gain compensation. The transmit power setting can also be increased to improve the signal-to-noise ratio.
Step-by-step explanation:
Contrast echocardiography is a technique used to enhance the visibility of the heart and blood vessels during an echocardiogram. One way to optimize contrast images is by adjusting the instrument settings. For example, increasing the gain can improve the visibility of low-contrast structures, while adjusting the time gain compensation can provide uniform brightness throughout the image. Another setting to consider is the transmit power, which can be increased to optimize the signal-to-noise ratio.
