Although many preprocessing functions make our image look better, unfortunately you cannot use them on this type of display.
What is a frozen screen?
100
This is a name for each individual location within a memory grid.
What is a pixel?
100
Just like you do with a book, this is the type of magnification that occurs after data has been sent to memory.
What is read?
100
This type of monitor technology displays both the odd and even lines simultaneously for quicker refresh rates.
What is non-interlaced?
200
Unlike the power output control, we don't need to worry about this when use the gain button.
What are patient bioeffects?
200
This preprocessing function helps a sonographer to clarify borders more distinctly by adding bright or dark highlights at interfaces.
What is edge enhancement?
200
This type of image quality is strongly influenced by the amount of memory within a system.
What is contrast resolution?
200
The ability for a system to 'travel back in time' and see what anatomy looked like in the moments before it was captured on a frozen screen is referred to as this type of technology.
What is Cine Review (aka Cineloop)
200
These types of monitors, used in older televisions, are now generally considered outdated by industry standards.
What are Cathode Ray Tube monitors?
300
This is the first part of demodulation in which negative radiofrequency amplitudes are converted to positive.
What is rectification?
300
Spatial compounding typically averages between ____ and ____ together in order to improve SNR, border distinction, and in reducing speckle.
What is 3 and 9?
300
In a 4 bit system, the strongest reflectors would be assigned to this binary number.
What is 15?
300
This function requires operations from both the front and back ends of a system in order to display data collected from two orthogonal scan planes.
What is 3D imaging?
300
A CRT uses this part of an atom to illuminate pixels from behind the screen.
What is an electron?
400
This part of compensation needs to increase when a sonographer scans through a dense liver.
What is the slope?
400
Refresh rate can be artifactually slow when this preprocessing function is set too high.
What is persistence?
400
Memory locations that do not receive any actual anatomical data from that location are able to be blended with the surrounding anatomy using this type of technology.
What is interpolation? aka pixel or spatial interpolation
400
This postprocessing technology allows echoes to be assigned colors instead of grayscale in order to improve visualization of subtle brightness changes.
What is tissue colorization?
400
PACS stands for this.
What is Picture Archiving Communication Systems?
500
The full dynamic range of the entire ultrasound system is around this many decibels.
What is 170?
500
DAILY DOUBLE!!!
What is DAILY DOUBLE!!
500
This is the number of bits your system must have if it were to send up to 1,024 brightness assignments to the display.
What is 10?
500
Postprocessing compression maps distribute the dynamic range in this type of manner.
What is non-linear?
500
This, according to your textbook, is the average dynamic range of the human eye.
