Part I
Calculate the crystal thickness, PD, DF, PRF, PRP, SPL, period, and distance to reflector if a 3 cycle
pulse emitted from a 3 MHz transducer if the echo time received was 0.130 ms in soft tissue.
PRF = c/2D
d=ct = (1540m/s) (.130ms) = (1540m/s) (.0
Part I
Calculate the PRP, PRF, PD, DF, wavelength, SPL, distance of reflector interface and period if
a 3 cycle pulse emitted from a 5 MHz transducer if the echo time received was 10 ms in soft
tissue. HINT: work in this order, and use the formula sheet:

Vector Quantities and Scalar Quantities
A quantity is something that you can measure. Quantities come in two kinds.
Scalar quantities only have whats called a magnitude, which is a number and some units. Exam

Why Mathematics Matter
Mathematics is the engine which drives physics.
Without understanding math:
Physics becomes pure memorization
Memorization is painful, boring, and not real knowledge

CHAPTER 2 - Sound
SOUND WAVE:
Mechanical energy transmitted through a
medium.
Repetitive changes in molecular structure
(displacement, density, pressure, particle
velocity) allow sound to travel through a
medium.
A medium is what is imaged (soft tissue,

FORMULAS
Velocity, rate, or speed: c = f
Wavelength: = c/f
Frequency: f = c/ and f = 1/T
Period: T = 1/f
Distance: d = ct, you divide by 2 if distance to interface, which is depth (D) is required from total distance,
AKA range equation or echo ran
Part I
Calculate the PRP, PRF, PD, DF, SPL, wavelength, period, and Axial Resolution if a 2 cycle pulse
emitted from a 10 MHz transducer if the echo time received was 0.26 ms in soft tissue.
PRP = 1/PRF

PROBLEM 1
Last week I used a stopwatch to measure the echo time of my snare drum in the hall outside my
classroom, which is 80 meters long. The average echo time was 10 milliseconds. Use your
understanding of the Echo Ranging formula to prove or disprove
