Stereotactic radiation is a specialized type of external beam radiation therapy. It uses focused radiation beams targeting a well-defined tumor using extremely detailed imaging scans. Radiation oncologists perform stereotactic treatments, often with the help of a neurosurgeon for tumors in the brain or spine. There are two types of stereotactic radiation. Stereotactic radiosurgery (SRS) is when doctors use a single or several stereotactic radiation treatments of the brain or spine. Stereotactic body radiation therapy (SBRT) refers to one or several stereotactic radiation treatments with the body, such as the lungs. Some doctors say an advantage to stereotactic treatments are they deliver the right amount of radiation to the cancer in a shorter amount of time than traditional treatments, which can often take six to 11 weeks. Plus treatments are given with extreme accuracy, which should limit the effect of the radiation on healthy tissues. One problem with stereotactic treatments is that they are only suitable for certain small tumors. Stereotactic treatments can be confusing because many hospitals call the treatments by the name of the manufacturer rather than calling it SRS or SBRT. Brand names for these treatments include Axesse, Cyberknife, Gamma Knife, Novalis, Primatom, Synergy, X-Knife, TomoTherapy, Trilogy and Truebeam. This list changes as equipment manufacturers continue to develop new, specialized technologies to treat cancers.
SRS or SrS may stand for: 
In general, radiation therapy (or radiotherapy) has developed with a strong reliance on homogeneity of dose throughout the tumor. Tomotherapy embodies the sequential delivery of radiation to different parts of the tumor which raises two important issues. First, this method is known as "field matching" and brings with it the possibility of a less-than-perfect match between two adjacent fields with a resultant hot and/or cold spot within the tumor. The second issue is that if the patient or tumor moves during this sequential delivery, then again, a hot or cold spot will result. The first problem can be overcome, or at least minimized, by careful construction of the beam delivery system. The second requires close attention to the position of the target throughout treatment delivery. All this can be done with during the radiation planning process which makes tomotherapy the most homogeneous radiation treatment delivery machine. The Corvus tomotherapy system achieved great popularity because it provided a mass market solution to IMRT very early compared to other vendors' systems. Generally speaking, dose homogeneity is less in IMRT than in 3D conformal radiation therapy which may account for the relative lack of concern regarding the field matching issue. At this time, the Hi-Art system manufactured by TomoTherapy Inc. is the primary tomotherapy device in use although there are still a number of Corvus systems being used. TomoTherapy TomoHD systems are also in use. Other radiation therapy equipment vendors have recently responded to the challenge of short treatment times coupled with a full 360 degree treatment arc by developing methods of delivering IMRT using arcs. The major difference is that these methods are implemented on standard medical linear accelerators, thereby providing for complete volumetric irradiation. TomoTherapy "beam on" times are comparable to normal radiation therapy treatment times (about 3–5 minutes beam on time for a common prostate treatment) but do add an additional 2–3 minutes for a daily CT. The daily CT is used to precisely place the radiation beam and allows the operator to modify the treatment should the patients anatomy change due to weight loss or tumor shrinkage (adaptive radiotherapy). Lung cancer, head and neck tumors, breast cancer, prostate cancer, stereotactic radiosurgery(SRS) and stereotactic body radiotherapy (SBRT) are some examples of treatments commonly performed using TomoTherapy. While the first clinical use of TomoTherapy was in 2002, at the University of Wisconsin, under the leadership of Dr. Minesh Mehta, M.D., there are now more than 300 sites across Canada, the United States, Europe and Asia. Due to their internal shielding and small footprint, TomoTherapy Hi-Art and TomoTherapy TomoHD treatment machines are the only radiotherapy treatment machines used in relocatable radiotherapy treatment suites. Two different types of suites are available: TomoMobile developed by TomoTherapy Inc. which is a moveable truck and Pioneer, developed by UK-based Oncology Systems Limited. The latter was developed to meet the requirements of UK and European transport law requirements and is a contained unit that is placed on a concrete pad, delivering radiotherapy treatments in less than five weeks. 
The Brazilian Telecommunications Society () is a scientific academy of Brazil. Created in 1983 with no competing financial interest, it is devoted to promoting the diffusion, the development and the interchange of ideas and results in the field of Telecommunications. The SBrT is co-sister society of the IEEE Communications Society. The meetings and conferences sponsored by SBrT are now a forum for scientific, technological debate. The SBrT holds an annual scientific congress, the "Brazilian Telecommunication Symposium" (Simpósio Brasileiro de Telecomunicações), and each four years, the I"nternational Telecommunication Symposium" – ITS (joint with IEEE). It publishes the scientific journal – The "Journal of Communication and Information Systems" (JCIS), co-sponsored by the IEEE Communications Society. The SBrT also publishes the «Série Brasport», a series of textbooks on Telecommunications and correlated fields.
