Parameters of the microsphere inclusion and the turbid medium. (a) ρp and ρ0 are the density of microspheres and the turbid medium, respectively (Ref. 32). (b) a is the radius of the microsphere (Ref. 32). (c) N0 is the average fluorophore concentration which is equal to the average microsphere concentration multiplied by the number of fluorophores per microsphere (Ref. 32). (d) ε and ϕ are the absorption cross section and quantum efficiency of fluorescent, respectively (Ref. 33). (e) γ and β are the kinematic viscosity and compressibility of the turbid medium, respectively (Refs. 23, 34). (f) P1 and c are the amplitude of pressure and the speed of the ultrasound wave (Refs. 1, 35).
