Ernst Schrott,Hermann Philipp Theodor Ammonth the biosystem and the incident energy. With respect to the incident field, features such as frequency, polarization, and mode are important parameters of such a radiative transfer. With respect to the biosystem, the spatial distribution of dielectric properties and their time as well as frequencymisanthrope 发表于 2025-3-23 21:50:12
Ernst Schrott,Hermann Philipp Theodor Ammonimages representing the distribution of positron emitting radionuclides (.C, .N, .O, .F...). The selected labeled molecule is administered to the patient and the P.C.T. allows to obtain its distribution in several transverse tomographic sections as a function of time. Many molecules have been labeleALIBI 发表于 2025-3-24 00:03:28
Ernst Schrott,Hermann Philipp Theodor Ammonery of the x-ray in 1895. But no period has been more fruitful, perhaps, than the last decade when developments have appeared at a remarkable pace. Through all these changes, however, the fundamental goals of diagnostic radiology have remained unaltered. Basically, these goals are:.o To develop incrstaging 发表于 2025-3-24 05:11:42
Heilpflanzen für Nerven, Psyche und Schlafally, with the growing variety and intensity of use of digital imaging modalities the need for communication of images and for computer compatible mass storage has drastically increased..The traditional film files have associated with them problems of slow access, loss of images, virtually no possib手段 发表于 2025-3-24 06:45:01
Heilpflanzenkunde für die Veterinärpraxisezoelectric transducers. Pulse-echo information may be displayed as an A-scan, an M-mode recording, as a two-dimensional B-scan (often obtained in real time), or as a C-scan. The Doppler effect gives rise to audible shift frequencies in ultrasound reflected from moving structures. This can be used fAPEX 发表于 2025-3-24 12:46:07
Heilpflanzenkunde für die Veterinärpraxisfor chemical analysis. The use of NMR for imaging purposes, however, was not realized until the first NMR zeugmatograms were produced by Lauterbur in 1972 (4). In past months, resolution on NMR studies has improved to the point that the images have sufficient anatomical information to rival those thVOC 发表于 2025-3-24 17:38:30

Heilungswunder – Medizinische Perspektive(n) nuclear medicine. Indeed, the image forming variable in PET is the distribution in the structure under study of a radionuclide administered systemically in the form of a selected radiopharmaceutical prior to the imaging procedure. Yet a number of specific features endow PET with a distinct identity
