If there is no difference in acoustic impedence, The ultrasound image is formed from reflected, Caused by interaction with a very small reflector, Only a portion of the soundwave returns to the, Not all of the soundwave is reflected, therefore, These waves will reflect from deeper tissue, The deeper the wave travels in the body, the, The amplitude/strength of the wave decreases with, The ultimate goal of any ultrasound system is to, ability to capture, preserve and display the, specifies how close together two objects can be, the ability to resolve two adjacent objects that, the combination of AXIAL and LATERAL resolution, the ability to resolve two adjacent objects of, the ability to distinguish very rapid events in, has acoustic impedance between that of tissue and, reduces the reflection of ultrasound at the, produce a voltage when deformed by an applied, The piezoelectric element/crystal produces the, Electrical pulses applied to the crystal cause it, This produces the transmitted ultrasound pulses, The frequency of the scanhead is determined by, Thinner elements produce HIGHER frequencies, Thicker elements produce LOWER frequencies, The frequency also affects the quality of the, the higher the frequency, the shorter the, the shorter the wavelength, the better the axial, Therefore, higher frequency scanheads produce, The HIGHER the frequency, the LESS it can, Bandwidth is the range of frequencies emitted by, Each crystal emits a spectrum of frequencies, A broadband scanhead is one which uses the entire, A narrowband scanhead uses only a portion of the, Reflected echoes return to the scanhead where the, The electrical signal is then processed by the, It coordinates and processes all the signals to, It is the main component responsible for image, The strength or amplitude of each reflected wave, The position of the dot represents the depth from, The brightness of the dot represents the strength, These dots are combined to form a complete image, Display screen divided into a matrix of PIXELS, How does the system know the depth of the, The system calculates how long it takes for the, The velocity in tissue is assumed constant at, DOPPLER is used to hear and measure blood flow, COLOR or CPA (Color Power Angio) is added to, M-mode uses a graphic representation to measure. - Emergency Ultrasound in Trauma Anthony J Weekes MD, RDMS Janet G.
