Radiosurgery: Radiosurgery is surgery using radiation, that is, the destruction of precisely selected areas of tissue using ionizing radiation rather than excision with a blade. Like other forms of radiation therapy, it is usually used to treat cancer.Cerebral arteriovenous malformationVestibular schwannomaNeurooncology: Neuro-oncology is the study of brain and spinal cord neoplasms, many of which are (at least eventually) very dangerous and life-threatening (astrocytoma, glioma, glioblastoma multiforme, ependymoma, pontine glioma, and brain stem tumors are among the many examples of these). Among the malignant brain cancers, gliomas of the brainstem and pons, glioblastoma multiforme, and high-grade (highly anaplastic) astrocytoma are among the worst.Arizona Accelerator Mass Spectrometry Laboratory: Arizona Accelerator Mass Spectrometry Laboratory focuses on the study of cosmogenic isotopes, and in particular the study of radiocarbon, or Carbon-14. As a laboratory, part of its aim is to function as a research center, training center, and general community resource.Stereotactic surgeryUniversity of Miami Division of Surgical Neurooncology: The Division of Surgical Neurooncology in the Department of Neurological Surgery and Sylvester Comprehensive Cancer Center at the University of Miami is one of the largest and most complete programs for brain tumor treatment in the United States. As the only academic medical center in the region, the University of Miami offers a unique and comprehensive approach to these conditions, with interdisciplinary discussion between neurosurgery, neurology, radiation oncology, and medical oncology.MeningiomaMicrovascular decompression: Microvascular decompression (MVD), also known as the Jannetta procedure,http://neurosurgery.ucsf.Central neurocytoma: Central neurocytoma, abbreviated CNC, is a rare, ordinarily benign intraventricular brain tumour that typically forms from the neuronal cells the septum pellucidum. The majority of central neurocytomas grow inwards into the ventricular system forming interventricular neurocytomas.Chen Zhongwei: Chen Zhongwei (Chinese:陈中伟, 1929–2004) was an expert of orthopedic surgery and microsurgery, one of the pioneers of the process of reattaching severed limbs.ParagangliomaExternal beam radiotherapyNeurosurgery: Neurosurgery (or neurological surgery) is the medical specialty concerned with the prevention, diagnosis, treatment, and rehabilitation of disorders which affect any portion of the nervous system including the brain, spinal cord, peripheral nerves, and extra-cranial cerebrovascular system.AANS – Patient InformationAutomatic exposure control: Automatic Exposure Control (AEC) is an X-ray exposure termination device. A medical radiography x-ray exposure is always initiated by a human operator.Yisrael Mordecai Safeek: (BS) (MD)Cranial nerve examinationImage-guided surgery: Today, doctors are using computerized technologies that are familiar to people in the consumer world to help fight cancer in the operating room. An important example of that application is image guided surgery (IGS) and it helps surgeons perform safer and less invasive procedures and remove brain tumors that were once considered inoperable due to their size and/or location.HyperintensityAntoni Jan GoetzGrain boundary diffusion coefficient: The grain boundary diffusion coefficient is the diffusion coefficient (during atomic diffusion) of a diffusant along a grain boundary in a polycrystalline solid.P.Trigeminovascular system: The trigeminovascular system consists of neurons in the trigeminal nerve that innervate cerebral blood vessels. It has been hypothesized that the trigeminovascular system may be involved in some types of headaches.Infantile hemangiopericytoma: Infantile hemangiopericytoma (also known as "Congenital hemangiopericytoma") is a cutaneous condition characterized by single or multiple dermal and subcutaneous nodules that may be alarmingly large at birth or grow rapidly.Philip D'Arcy HartPituitary adenomaAbscopal effect: The abscopal effect is a phenomenon in the treatment of metastatic cancer where localized treatment of a tumor causes not only a shrinking of the treated tumor but also a shrinking of tumors in different compartments from the treated tumor. Initially associated with single-tumor, localized radiation therapy, the term has also come to encompass other types of localized treatments such as electroporation and intra-tumoral injection of therapeutics.Ferroelectric polymers: Ferroelectric Polymers"Ferroelectric Properties of Vinylidene Fluoride Copolymers," by T. Furukawa, in Phase Transitions, Vol.Metastasectomy: In oncology, metastasectomy is the surgical removal of metastases, which are secondary cancerous growths that have spread from cancer originating in another organ in the body.Irradiance: In radiometry (measurement of electromagnetic radiation), irradiance is the radiant flux (power) received by a surface per unit area, and spectral irradiance is the irradiance of a surface per unit frequency or wavelength, depending on whether the spectrum is taken as a function of frequency or of wavelength. The SI unit of irradiance is the watt per square metre (), while that of spectral irradiance is the watt per square metre per hertz (W·m−2·Hz−1) or the watt per square metre per metre (W·m−3)—commonly the watt per square metre per nanometre ().TruebeamGlazing agent: A glazing agent is a natural or synthetic substance that provides a waxy, homogeneous, coating to prevent water loss from a surface and provide other protection.Spinal tumorCerebral hemorrhagePituitary ACTH hypersecretionParinaud's syndrome
