What are some important considerations when selecting an appropriate pre-set for an ultrasound examination?

<p>Some important considerations when selecting an appropriate pre-set for an ultrasound examination include matching the pre-set to the type of examination (e.g., cardiac, abdomen, superficial structures) and avoiding using the wrong pre-set for the desired image quality.</p> Signup and view all the answers

What steps can be taken to optimize the depth of penetration during an ultrasound exam?

<p>To optimize the depth of penetration during an ultrasound exam, one can select an approximate depth of penetration (magnification or arrows), adjust the overall gain and power settings to mid/low values, and fine-tune the depth of penetration by adjusting the focal zone.</p> Signup and view all the answers

How can the overall picture quality be adjusted during an ultrasound exam?

<p>The overall picture quality during an ultrasound exam can be adjusted by increasing or decreasing the overall gain and power settings as necessary to achieve a good quality image.</p> Signup and view all the answers

What are the consequences of setting the gain and power settings too low or too high during an ultrasound exam?

<p>If the gain and power settings are set too low during an ultrasound exam, the detail in the background image may be lacking. If they are set too high, the image may appear too bright.</p> Signup and view all the answers

Why is adjusting the focal zone to the middle of the organ important in ultrasound imaging?

<p>Adjusting the focal zone to the middle of the organ is important in ultrasound imaging because it ensures that the organ fills the whole screen, optimizing the image quality.</p> Signup and view all the answers

What are the different ways to optimize an ultrasound image?

<p>The different ways to optimize an ultrasound image include imaging in the 3 standard planes (dorsal, sagittal, transverse), imaging in non-standard planes, sliding and angling the transducer, and rotating the transducer.</p> Signup and view all the answers

What does knobology mean in the context of ultrasound imaging?
