65 -- PHASED ARRAY BRAIN SPECTROSCOPY COIL SOL RFQ: 261-0290-99 DUE 092299 POC Maria Graciano, 415-750-2066 This contract action is for the purchase of the phased array brain spectroscopy coil. This coil has mutiple (4) preamplifier receivers to be used on the Siemens Magnetom VISION MRI/MRS system housed at the MR Unit. The coil is designed to cover the entire brain of average adults, and will provide enhanced signal-to-noise particularly over the cortex and outer regions of the brain. The array coil will be fixed-tuned array that will accommodate typical patients in the weight arange from 75 to 200 pounds. The coil will consist of an array of eight individual coils, and will provide for a possible future expansion of inclusion of eight preamplifiers, one for each coil. The coil will be delivered with four preamplifiers, one for each set of opposing coils. The amplifiers will have a gain of at least 25dB, and a noise figure of less than 0.5dB. The array coil is to be tested for isolation of each individual coil with each coil attached to its own separate receive, and in this configuration each individual coil will be isolated (decoupled) from all other coils by at least 20dB. Finally, individual coils will be decoupled from the body coil during RF transmission by at least 30dB, for body coil transmit fields of up to 60 uT. The coil will fit in a fixed position on the VISION patient table, and the coil connector will plug into the VISION coil connector, and establish a coil code as requested by the customer. The coil housing will be made from a material tht does not produce noticeable signal at the lowest echo time of the MRI system, and will cover all live electronics. In addition, the coil will provide for visual access outside of the magnet through use of a mirror (not supplied), and will also provide for auditory stimulation through holes in the housing in the vicinty of the ears. The sensitivity of the array coil will exceed the standard Siemens VISION MRI headcoil by at least 15% in all parts of the brain, and by at least a factor of 2 in the outermost regions (cortex) of the brain. Furthermore, the presence of the coil will not materially degrade the ability to shim over the brain. The coil warranty is for a period of one year, and covers workmanship, materials, all components, and design. The Government intends to solicit and negotiate with only one source under authority of FAR 6.302. This announcement constitutes the only solicitation. A WRITTEN SOLICITATION WILL NOT BE ISSUED.
