**Radiative Transfer Equation And Diffusion Theory For Photon Transport In Biological Tissue**

Photon transport in biological tissue can be equivalently modeled numerically with Monte Carlo simulations or analytically by the radiative transfer equation (RTE). However, the RTE is difficult to solve without introducing approximations. A common approximation summarized here is the diffusion approximation. Overall, solutions to the diffusion equation for photon transport are more computationally efficient, but less accurate than Monte Carlo simulations.

### Famous quotes containing the words transfer, equation, theory, transport, biological and/or tissue:

“I have proceeded ... to prevent the lapse from ... the point of blending between wakefulness and sleep.... Not ... that I can render the point more than a point—but that I can startle myself ... into wakefulness—and thus *transfer* the point ... into the realm of Memory—convey its impressions,... to a situation where ... I can survey them with the eye of analysis.”

—Edgar Allan Poe (1809–1849)

“Jail sentences have many functions, but one is surely to send a message about what our society abhors and what it values. This week, the *equation* was twofold: female infidelity twice as bad as male abuse, the life of a woman half as valuable as that of a man. The killing of the woman taken in adultery has a long history and survives today in many cultures. One of those is our own.”

—Anna Quindlen (b. 1952)

“It makes no sense to say what the objects of a *theory* are,

beyond saying how to interpret or reinterpret that *theory* in another.”

—Willard Van Orman Quine (b. 1908)

“One may disavow and disclaim vices that surprise us, and whereto our passions *transport* us; but those which by long habits are rooted in a strong and ... powerful will are not subject to contradiction. Repentance is but a denying of our will, and an opposition of our fantasies.”

—Michel de Montaigne (1533–1592)

“When human beings have been fascinated by the contemplation of their own hearts, the more intricate *biological* pattern of the female has become a model for the artist, the mystic, and the saint. When mankind turns instead to what can be done, altered, built, invented, in the outer world, all natural properties of men, animals, or metals become handicaps to be altered rather than clues to be followed.”

—Margaret Mead (1901–1978)

“Whether or not his newspaper and a set of senses reduced to five are the main sources of the so-called “real life” of the so- called average man, one thing is fortunately certain: namely, that the average man himself is but a piece of fiction, a *tissue* of statistics.”

—Vladimir Nabokov (1899–1977)
