66 -- WHOLE BODY POSITRON EMISSION TOMOGRAPH SOL CC-96-12 POC Johnnie L. Rice, Contracting Officer, 301-402-3086. The Clinical Center of the National Institutes of Health intends to negotiate with General Electric Medical Systems for a one-year contract with four 12-month options to furnish, deliver, and install a GE Advance whole-body positron emission tomography (PET) scanner and associated maintenance. The project includes providing all components required for acquisition and processing of PET data, including all hardware components and software tools. The system shall be capable of producing reconstructed cross-sectional and volume images of radioisotope activity concentration with accurate corrections for physical factors associated with PET. To meet the current research protocols established using previously purchased PET Scanner equipment, the PET scanning system to be obtained by this contract must interface with the existing GE Advance PET scanner currently in operation at the NIH. This requirement applies to all performance characteristics of the system and all hardware and software features, including future software releases. The following benchmarks and performance characteristics are mandatory: Reconstruction time for 35 128x128 2-D images less than 60 sec; Reconstruction time for 35 128x128 3-D images less than 5 min; Transverse spatial resolution in 2-D and 3-D less than 5.6 mm at 1 cm radial distance, worsening by no more than 1.0-mm at 10cm, Slice thickness in 2-D less than 5.0 mm at the center, worsening by no more than 2.0 mm at 10 cm, Slice thickness in 3-D less than 6.5 mm at the center; Intrinsic scatter fraction in 2-D less than 12%; Trues volume sensitivity in 2-D greater than 200 kcps/(microCi/cc); Trues volume sensitivity in 3-D greater than 1160 kcps/(microCi/cc); Count rate performance: activity concentration greater than 5 microCi/cc (2-D) and greater than 0.8 microCi/cc (3-D) for either of (i) randoms rate equal to trues rate or (i) 50% deadtime and activity concentration greater than 7.5 microCi/cc (2-D) and greater than 1.1 microCi/cc (3-D) for saturated trues rate; NEMA intraslice uniformity less than 10%; volume uniformity less than 15%; interslice uniformity less than 2%; Remnant scatter fraction in 2-D and 3-D less than 6% in any slice; Remnant bias after deadtime and randoms corrections less than 5% at 5 microCi/cc (2-D) and at 0.8 microCi/cc (3-D); Error in attenuation correction less than 3% in water-filled insert and less than 10% in air and solid inserts for 2-D and 3-D. The proprietary nature of the hardware and software provided with the General Electric Medical Systems Advance PET scanner and the unique capability of General Electric Medical Systems to provide all components of a system capable of interfacing with existing NIH-owned equipment and software make competition unfeasible for this contract. Authority: 41 U.S.C. 253(c)(1), as set forth in FAR 6.302-1. All responses must be written and received within 45 calendar days from the published date of this notice. ORAL COMMUNICATIONS IS NOT ACCEPTABLE AND WILL NOT BE HONORED. Any firm believing it has the ability to meet the Government's performance requirements and current research protocol specifications as described above are invited to respond to this notice furnishing clear and convincing documentation demonstrating their ability to meet, at a minimum, all the stated performance and capabilities to accomplish the subject contract. The Government will NOT pay for preparation or submission of any information submitted in response to this synopsis. See Numbered Note(s): 22 (0129)
