LASER TERMS

Question 1

the mechanism by which nonionizing optical radiation from lasers and noncoherent sources in the visible and near IR spectral range are absorbed by endogenous chromospheres to elicit photo physical and photochemical events at various biological scales, leading to physiological changes and therapeutic effects

Answer 1

photobiomodulation

Question 2

name this laser category?

cells are destroyed

tissue ablation and coagulation

photo surgical reaction

Answer 2

high level laser therapy

Question 3

name this laser category?

cells are damaged but alive

protein denaturation

Answer 3

medium level laser therapy

Question 4

name this laser category?

level of cellular activation increases

remains below the damage threshold

cellular photoactivation

photo therapeutic reaction

Answer 4

low level laser therapy

Question 5

this is the ability of the ;user to provide enough photons within the tissues to initiate a biological response within the individual cells is a function of:

wavelength

power

target energy

freaquency

Answer 5

dose

Question 6

this is determined by the length of the wavelength

Answer 6

depth of penetration

Question 7

determines the number of photons at the depth the wavelength will take it

Answer 7

power

Question 8

name this variable of power:

faster treatment for larger areas and deeper conditions

Answer 8

rate

Question 9

name this variable of power:

more energy applied at surface, the more energy will get to all tissue layers

Answer 9

`penetration

Question 10

name this variable of power:

impact on afferent nerves

Answer 10

fast pain relief

Question 11

name this variable of power:

more power equals?

Answer 11

more photonics energy delivered
