| Question | Answer |
| What is the highest intensity? | SPTP |
| Intensities are important in the study of? | biological effects |
| Which intensity is important in the study of bioeffects? | SPTA |
| Currently, the AIUM states that no biologic effects are confirmed. The AIUM uses what intensity for a focused beam? | <1 W/cm sq. |
| The thermal index is related to? | tissue heating |
| What is the intensity suggested by the AIUM for an unfocused beam? | <100 mW/cm sq. |
| What is directly related to intensities? | duty factor |
| Which is the lowest intensity? | SATA |
| Is The intensity of the beam the same throughout the beam? | no |
| If power remains the same and area is increased, what happens to the intensity? | it decreases |
| If power is increased and the area is decreased, what happens to the intensity? | it increases |
| What best describes the intensity of a continuous wave beam? | the beam is uniform across time but not across space |
| temporal | all time (transmit and receive) |
| pulsed | only transmit time |
| spatial | refers to distance or space |
| What is the unit for measuring intensity? | W/cm squared |
| What are the appropriate knobology adjustments? | (ALARA) overall gain, TGC, then power output |
| Rank the intensities from lowest to highest | SATA, SPTA, SPPA, 1m, SPTP |
