Retaining only the first-order expansion of a perturbation series of the diffusion equation is referred to as the Born approximation. , in hemodynamic functional studies), this results in: ð dFðrs ,rd Þ ¼ À dma ðr ÞF0 ðrs ,r ÞG0 ðr,rd Þd 3 r; (1:31) V where dF is the difference of fluence radiated from the light source and measured by the detector; dma is the change in absorption coefficient; and the integral kernel F0 (rs ,r)G0 (r,rd ) is the product of the fluence (evaluated at r in response to a source at rs ) and Green’s function (evaluated at r in response to a source placed at the detector position rd ).

Accidental coincidences refer to events in which the line integral formed by the detection of the two g-rays is assigned incorrectly. These occur due to the finite coincidence resolving time of the system, g-rays passing through the crystal and not being detected, and the presence of background radiation. The most common method of estimating accidental coincidences uses additional parallel timing circuitry, which splits the logic pulse from one of the detectors into two components. The first component is used in the standard mode to measure the total number of coincidences.

99m Tc is obtained by flowing an eluting solution of saline through the generator. The solution washes out the 99m Tc, which binds very weakly to the alumina, leaving the 99 Mo behind. The 99m Tc eluted from the generator is in the form of sodium pertechnatate, NaTcO4 . The majority of radiotracers, however, are prepared by reducing the pertechnetate to ionic technetium (Tc4þ ) and then complexing it with a chemical ligand that binds to the metal ion. Examples of ligands include diphosphonate for skeletal imaging, diethylenetriaminepentaacetic acid (DTPA) for renal studies, hexamethylpropyleneamineoxime (HMPAO) for brain perfusion, and macroaggregated albumin for lung perfusion.
