Biomedical Optics: Principles and Imaging by Lihong V. Wang PDF


By Lihong V. Wang

This entry-level textbook, overlaying the realm of tissue optics, relies at the lecture notes for a graduate direction (Bio-optical Imaging) that has been taught six instances by way of the authors at Texas A&M college. After the basics of photon shipping in organic tissues are validated, a variety of optical imaging strategies for organic tissues are coated. The imaging modalities contain ballistic imaging, quasi-ballistic imaging (optical coherence tomography), diffusion imaging, and ultrasound-aided hybrid imaging. the elemental physics and engineering of every imaging strategy are emphasised.

Substituting Eq. 4) into Eq. 3), we obtain a. 6) where size parameter x is defined as x = ka. 7) NUMERICAL EXAMPLE OF RAYLEIGH THEORY Substituting Eqs. 2) into Eq. 6), we obtain os oc a6/\4. Eq. 8) The scattering efficiency depends only on x and ηκ\. If nre\ is close to unity, Eq. 9) Note that rcrei can be complex, in which case the imaginary part is responsible for absorption. 3. NUMERICAL EXAMPLE OF RAYLEIGH THEORY The Rayleigh theory can compute scattering cross section os and scattering efficiency Qs.

5. 6. 7. 00 g/cm3 Concentration of spheres in background by weight: C wt = 1 x 10~5 We compute in SI units as follows: 1. 09 x 107 m- 1 . 2. 18. 3. 209. 4. From Eq. 15 x 10~20 m2. 5. From Eq. 83 x 10~5. 6. Compute the number density of scatterers Ns. For a sphere, the mass density is Ps = ms/Vs, where ms denotes the mass and Vs denotes the volume—Vs = (4/3)πα 3 . For the background, the mass density is p^ = my, j V&, where m^ is the total mass of the background and V& is the total volume of the background.

Substituting it into Eq. 43), and then dividing the equation by / ? ( Γ ) Θ ( Θ ) Φ ( Φ ) , we obtain 1 a / 22dR\ 1 3 / . dS\ 1 32Φ f 2 Λ -Ϊ2 \r — ) + -T2 (sinG— 1 + 2 = T + * = 0. 44) Multiplying Eq. 44) by r2 sin2 Θ, we see that the third term on the left-hand side depends only on φ, whereas the other terms are independent of φ. Thus, we let 1 32Φ φ " ^ 2 constant = — m . 47) From condition Φ(0) = Φ(2π), we have m = 0, ± 1 , ±2, part from Eq. 44) is The r0-dependent l a / 27dR\ i a / .
