, -higher absorption occurs in tissue with a high collagen rate and with higher
us frequencies
ultrasound energy absorption - 🧠ANSWER ✔✔best in tendon, ligament,
fascia joint capsule and scar tissue
reflection of a sound wave - 🧠ANSWER ✔✔occurs when the wave passes
between two tissues and a fraction of the wave "bounces" back
refraction - 🧠ANSWER ✔✔occurs when the US signal is deflected from a
straight path and the angle of deflection is away from the transducer
coupling agents - 🧠ANSWER ✔✔gel and water
US parameters - 🧠ANSWER ✔✔-effective radiating area (ERA) -cm2
-beam nonuniformity ratio (BNR)- ratio
-intensity- w.cm2
-frequency- MHZ
-duty cycle-%
effective radiating area (ERA) - 🧠ANSWER ✔✔-area of the crystal that
actually produces sound waves
