PET systems use multiple detectors connected by a coincidence circuit that are distributed in opposite directions and encircle the patient. During this process two annihilation photons with an energy of 511 keV each are emitted in an angle of 180° ± 0.25° (see Figure 1). After a certain reach in tissue (depending on the nature of both the radionuclide and the tissue), the positron will interact with an electron and this interaction will result in an annihilation event. These radioactive nuclides decay by positron emission. For this imaging method so-called PET tracers, which are biological molecules or sometimes artificial building blocks for specific targets labeled with positron emitters (e.g., gallium-68, fluorine-18), are intravenously injected into the patient. It allows a non-invasive and quantitative imaging of cellular and molecular events in patients, giving functional information in contrast to morphological information obtained from conventional imaging techniques like computed tomography (CT) or magnetic resonance imaging (MRI). PET is a commonly used imaging technique in nuclear medicine. These kits allow decentralized tracer production and therefore enable the application of the radiotracer to patients who do not live in the vicinity of a centralized production site. a kit preparation for 68Ga-labeling of DOTA-TATE (NETSPOT TM, AAA, a Novartis Company, Saint-Genis-Pouilly, France) was approved by the FDA on 1 June 2016. Use of this kit along with an authorized 68Ge/ 68Ga-generator enables on-site preparation of Ga-DOTA-TOC even in small facilities. Also in Europe, a kit preparation for 68Ga-labeling of DOTA-TOC (SomaKit TOC ®, AAA, a Novartis company, Saint-Genis-Pouilly, France) was approved by the European Medicines Agency (EMA) on 8 December 2016. The ready-to-use 68Ga-labeled peptide was already approved in some European countries (Austria, Germany, and France) in 2016 (IASOtoc ®, IASON GmbH, Graz, Austria) and in 2018 (TOCscan ®, ITM AG, München, Germany). Holder of the marketing authorization is the UIHC–PET Imaging Center (University of Iowa Health Care (UIHC)), in Iowa, USA. With its advanced collection and visualization of data NetSpot provides its users with a comprehensive and complete WiFi site survey solution.On 21 August 2019, Ga-DOTA-TOC was approved by the Food and Drug Administration (FDA) for positron emission tomography (PET) imaging of somatostatin receptor (SSTR)-positive gastroenteropancreatic neuroendocrine tumors.

With all this work done well the wireless signal is less likely to spill outside, where a war driver can get their hands on it.
With NetSpot one can also check the security settings (Open, WEP, WPA/WPA2 Personal/Enterprise), non-broadcasting SSIDs and WiFi signal strength. NetSpot is a perfect helper for network security specialists in locating and eliminating rogue access points, detecting unauthorized workstations, avoiding cross-channel interference and getting rid of false-positive intrusion alerts. Wireless Site survey is also an important part of wifi security analysis.

With the help of site survey you will know what type of equipment to get and where to install it.
The main goal of a WIFI site survey is determining the feasibility of implementing a wireless network in a specific area and finding the best spots for access points and other equipment like cables and antennas. It will reveal areas of channel interference and dead zones, and will help you tremendously to build a solid network. The effective way to obtain this information is a wireless site survey. When working on a Wi-Fi network that will provide an optimal coverage, you'll need a solid research and understanding the radio frequency behavior at the spot.
