Anger (1 ) , a number of papers describing both the physical characteristics of the instrument and its ap plications have been published (2—12) . However, the performance of the gamma camera has usually been discussed in terms of the parameters fundamental to a conventional scanner, and insufficient emphasis has been placed on characteristics that are unique to the camera. It is, of course, n...
When a speaker talks, the consequences of this can both be heard (audio) and seen (visual). A novel visual phonemic restoration task was used to assess behavioral discrimination and neural signatures (event-related potentials, or ERP) of audiovisual processing in typically developing children with a range of social and communicative skills assessed using the social responsiveness scale, a measu...
wireless sensor networks (wsns) are one of the most interesting consequences of innovations in different areas of technology including wireless and mobile communications, networking, and sensor design. these networks are considered as a class of wireless networks which are constructed by a set of sensors. a large number of applications have been proposed for wsns. besides having numerous applic...
فرض کنید $ r $ حلقه ای جابه جایی و یکدار و $ z(r) $ مجموعه مقسوم علیه های صفر حلقه $ r $ باشد. گراف جمعی حلقه $ r $ گرافی است که رئوس آن عناصر حلقه می باشد و دو راس متمایز $ x $ و $ y $ مجاورند اگر و تنها اگر $ x+y in z(r) $ . این گراف با نماد $ t(gamma(r)) $ نمایش داده می شود. در این پایان نامه دو زیر گراف $ t_0(gamma(r)) $ و $ z_0(gamma(r)) $ که رئوس آن به ترتیب $ r ^* $...
BACKGROUND The performance of a prototype novel digital single-photon emission computed tomography (SPECT) camera with multiple pixelated CZT detectors and high sensitivity collimators (Digital SPECT; Valiance X12 prototype, Molecular Dynamics) was evaluated in various clinical settings. Images obtained in the prototype system were compared to images from an analog camera fitted with high-resol...
A prototype of the MeV gamma-ray imaging camera based on the full reconstruction of the Compton process has been developed. This camera consists of a micro-TPC that is a gaseous Time Projection Chamber (TPC) and scintillation cameras. With the information of the recoil electrons and the scattered gamma-rays, this camera detects the energy and incident direction of each incident gamma-ray. We de...
