A method is provided for imaging a vasculature of a patient using an MRI system with an array of local coils. The projection device further comprises an imaging system. The instant invention further provides a rapid, sensitive, and consistent method for the specific detection of WNV by employing diagnostic assays having the antigen NS5 which is specifically reactive with anti-WNV antibodies but not cross-reactive with antibodies against other flaviviruses such as JEV, SLEV, or DENV. Using the time difference of arrival of each receiver, the location in 3-dimensional space of each receiver, and the speed of sound the position of the transmitter in 3-dimensional space relative to the reference receiver may be found. Furthermore, the system generates a final query to generate a final table from the intermediate table sequentially generated by the recursive query.
