This is a combined synopsis/solicitation for commercial items prepared in accordance with the format in Subpart 12.6 as supplemented with additional information included in this notice. This announcement constitutes the only solicitation; proposals are being requested and a written solicitation will not be issued.
The solicitation number is NIH-NINDS-CSS-19-5381335 and the solicitation is issued as a request for quote (RFQ).
This acquisition is for a commercial item or service and is conducted under the authority of the Federal Acquisition Regulation (FAR) Part 13-Simplified Acquisition Procedures; FAR Subpart 13.5-Simplified Procedures for Certain Commercial Items; and FAR Part 12-Acquisition of Commercial Items, and is expected to exceed the simplified acquisition threshold.
The solicitation document and incorporated provisions and clauses are those in effect through Federal Acquisition Circular 2019-03 thru July 12, 2019.
The associated NAICS code 334516, "Analytical Laboratory Instrument Manufacturing" and the small busisess size standard 1000 employees. This requirement is full and open with no set-aside restrictions.
Contract Type: A firm-fixed price type contract is contemplated for this requirement.
Background Information and Objective:
The NIH Mouse Imaging Facility (MIF) is a shared, intramural resource for preclinical animal imaging studies. The MIF provides the NIH intramural research community access to modern radiological imaging equipment optimized for rodents and other laboratory animals for noninvasive imaging studies. The MIF provides intellectual, technical and material support for NIH investigators. MIF imaging resources include: magnetic resonance imaging (MRI), micro-computed tomography (Micro-CT), high frequency ultrasound with photoacoustic imaging, bioluminescence and fluorescence imaging (optical imaging). The MIF is dedicated to providing state-of-the-art anatomical, functional and molecular medical imaging capabilities for animal models of human disease.
The objective of this acquisition is to obtain a new high resolution ex-vivo micro CT scanner to replace the current one that is no longer supported by the manufacturer.
Statement of Need and Purpose:
The NIH Mouse Imaging Facility (MIF) needs a new high resolution ex-vivo Micro Computed Tomography (microCT) imager to replace the current scanner. The current scanner is no longer supported by the manufacturer. The scanner is required to capture extremely high resolution radiographic images of very small samples such as mouse teeth and bones, zebrafish and fruit flies. In the past five (5) years twelve (12) different NIH institutes have used the current ex-vivo microCT scanner and almost every institute has imaged tissue samples over its usage history. The ex-vivo microCT continues to be a MIF imaging resource in high demand.
Salient Characteristics:
The high resolution desktop microCT imaging system must include a minimum of the following characterstics:
• Scanner shall Include a 16 megapixel 14-bit cooled CCD camera with a minimum three offset positions equaling three times the field of view.
• Equipment shall produce reconstructed volumes up to 209 Megapixel (14450x14450 pixels) virtual slices through objects, more than 2600 such slices after a single scan.
• Equipment must use phase-contrast enhancement to visualize object details as small as 0.35um (minimum pixel size).
• Scanner must contain an acquisition geometry with ability to simultaneously adjust the sample distance and detector distance to the X-ray source automatically. This means that for most scans the sample can be in the Near position, increasing scan speed by 5X. For either the highest resolution scan or the largest samples, the detector moves into the Mid or Far positions.
• Camera shall provide continuous magnification from 0.34um - 25um pixel sizes.
• Scanner shall contain a field of View X-ray Detector for samples up to 75mm in diameter, 70 mm high. Detector has 5000 pixels horizontally and 3280 pixel vertically for large field of view in a single scan. The scanner shall have the capability for reconstruction arrays of 14,450×14,450 (200Mp+ in a single reconstructed image).
• System shall have a maintenance-free X-ray source (20-100kV, 10W) with.
