66 -- CARDIOVASCULAR MAGNETIC RESONANCE INSTRUMENT SOL NHLBI-HL-P-95-106 POC Kathleen J. Van Steelant, Contract Specialist, (301) 435-0366. It is the intent of the National Heart, Lung, and Blood Institute (NHLBI) to acquire a Cardiovascular Magnetic Resonance Instrument for installation in the Laboratory of Cardiac Energetics in Bethesda, Maryland. Specifically, the offeror(s) shall: 1) Construct a MRI/MRS device which will be capable of state-of-the-art cardiovascular MR studies in humans; 2) Install the device into the in vivo NMR center at the National Institutes of Health in Bethesda, Maryland; 3) Confirm or demonstrate the operations of the instrument according to the performance specificatioons, on site; 4) Train the Laboratory of Cardiac Energetics staff in any special hardware or software which will be required for the routine operation of the system; 5) Provide a full service maintenance agreement for the instrument for a three year period to begin upon expiration of the warranty period; and 6) Provide a research contract to aid in the development of cardiovascular MR applications in the NHLBI. The instrument must meet the following minimum specifications: 1) MAGNET/MAGNETIC FIELD SHIMS: Minimum field strength 1.0 Tesla, must operate with minimal magnetic interference with existing MR instruments (magnetic field shielding is desirable), field homogeneity 0.3 ppm over 20cm DSV; 2) GRADIENTS: Must provide a minimum gradient strength of 20 mT/m, must be designed using state-of-the-art technologies with regard to reducing short term and long term magnetic field eddy current effects during gradient switching, slew rate minimum of 50 T/m/sec, overall clear bore of system, including radiofrequency body coil must be 55 cm or greater; 3) CONSOLE: High rate digital receiver, multinuclear capabilities, arbitrary waveform generation for rf and gradients, industry standard CPU; 4) RADIOFREQUENCY COILS: Surface coil or phase array detection system for the chest to optimize signal to noise characteristics, quadrature head coil, extremity coil, assorted surface coils for peripheral vasculature studies; 5) GENERAL CONSIDERATIONS AND OVERALL SYSTEM PERFORMANCE: System must be capable of collecting state-of-the-art cardiovascular images from the human heart and peripheral vasculature; and 6) INSTRUMENT MAINTENANCE AND RESEARCH TECHNICAL SUPPORT: Extended maintenance and technical/research support is anticipated for the proposed instrument. A firm fixed-price type contract will be negotiated for the instrument portion of the contract. A cost-reimbursement type contract will be negotiated for the maintenance and technical support portions of the contract. Delivery and installation of the instrument is anticipated within six (6) months after the contract award. Only a fully installed and functional instrument will be accepted. Tests will be performed to ascertain that the instrument is functional before final acceptance. It is anticipated that Request for Proposal (RFP) NHLBI-HL-P-95-106 will be issued on or about June 16, 1995. Copies of the RFP may be obtained by writing to the National Heart, Lung, and Blood Institute, Contracts Operations Branch, Procurement Section, 6701 Rockledge Drive (RKL2), Room 6143, Mail Stop Code 7902, Bethesda, Maryland 20892-7902, Attention: Kathleen J.
