Collimator characteristics for radioisotope scanning.
For scintigraphic instruments such as scanners and scintillation cameras, collimatore with greatly dif ferent characteristics have become available during recent years. In general little information is given concerning the performance of focused collimatore to the physician or physicist who has to select the proper collimator for a particular application.! Only the number of holes, the focal le...
متن کاملRadioisotope scanning in posterior fossa lesions.
It has been alleged that radioisotope scanning of posterior fossa lesions is of little value (1-8) or at best, difficult (9,10) and frequently unrewarding (11). Some clinics even report the virtual abandonment of posterior fossa scanning (12,13). On the other hand, there are those who maintain that scanning of the posterior fossa is a worthwhile adjunct in the evaluation of lesions in that re g...
متن کاملRadioisotope scanning in auxiliary liver transplantation.
The same general techniques were used in both the canine and human studies. Intravenously administered rose bengal 1131 was administered to dogs in a dose of 50 microcuries and to patients in a dose of 150 microcuries; scans were obtained at 5 minutes. In the canine experiments employing gold, 50 microcuries of Aulg8 were used with scanning at 15 minutes; in 2 adult human beings 200 microcuries...
متن کاملFluorescence resonance energy transfer scanning near-field optical microscopy.
The method of fluorescence resonance energy transfer scanning near-field optical microscopy (FRET SNOM) consists in the separation of a FRET pair between an SNOM tip and a sample. The donor (or acceptor) centre is located at the tip apex and scanned in the vicinity of a sample while acceptor fluorescence (or donor-fluorescence quenching) is detected. It is shown that the spatial resolution for ...
متن کاملOrthogonal basis for the optical transfer function.
We propose systems of orthogonal functions qn to represent optical transfer functions (OTF) characterized by including the diffraction-limited OTF as the first basis function q0=OTFperfect. To this end, we apply a powerful and rigorous theoretical framework based on applying the appropriate change of variables to well-known orthogonal systems. Here we depart fro...
