This is NOT a solicitation for proposals, proposal abstracts, or quotations. The purpose of this notice is to obtain information regarding the availability and capability of all qualified sources to perform a potential requirement. This notice is issued to help determine the availability of qualified companies under the NAICS Code 541380 - Testing Laboratories Services, technically capable of meeting the Government requirement, to determine the method of acquisition, and availability of domestic sources manufactured in the United States in sufficient and reasonably available commercial quantities and of a satisfactory quality. It is not to be construed as a commitment by the Government to issue a solicitation or ultimately award a contract. Responses will not be considered as proposals or quotes. No award will be made as a result of this notice. The Government will NOT be responsible for any costs incurred by the respondents to this notice. This notice is strictly for research and information purposes only. Small businesses are encouraged to respond. For equipment/supply requirements, responses must include the place of manufacturing (i.e. address if supply/equipment is a domestic end product and include country of manufacture). For equipment/supply requirements, small businesses must also address the size status of the manufacturer under the applicable NAICS code (i.e. address Non-Manufacturer Rule). Statement of Need and Purpose: The MRI Section of the NIA/IRP (National Institute on Aging/Intramural Research Program) specializes in studies of tissue response to aging, and age-related pathology; there exists an ongoing, and increasing, need for high-quality multi-modality imaging studies. Many of these studies are extremely challenging from the perspective of image information content. The purpose of our work is to greatly augment the information content of MRI non-invasive characterization and diagnosis of brain and connective tissue pathology, and deepen our understanding of microstructural changes that occur with aging and diseases of aging. Background Information and Objective: Studies in quantitative MRI are extremely challenging, with optimal acquisition strategies representing tradeoffs between speed of acquisition, image pixel resolution, unavoidable patient motion, sequence design (with e.g. greater or lesser sensitivity to motion), and other considerations. While we have for many years been at the forefront of acquisition-end developments for producing high-quality images, processing-end developments have been much less well-studied by our group and in the MRI community overall. However, with the advent of increased machine learning perspectives and greatly expanded computational power, new ideas and implementations in data processing for optimal imaging protocols are of increasing interest. The goal of all of this, in our laboratory, is towards the detailed characterization of central nervous system. Purchase Description: NIDA requires the Application of mathematical optimal transport theory to outstanding problems of image enhancement and artifact reduction in magnetic resonance imaging. Specific Requirements: Provide a detailed literature search to identify suitable modalities for the optimal transport approach, as well as those modalities for which further back-end (post-acquisition) processing will be most effective and provide the most additional information. This will be in close collaboration with the PI, who is the domain-knowledge expert in MRI. Establish the mathematical framework for the associated optimization problems using the Wasserstein-1 metric as follows: i) for image inpainting, ii) for multimodality superresolution, and iii) for localized artifact removal Explore available nonlinear optimization methods to address the optimization problems described above and identify those that are most promising. Translate the solutions of these optimization problems into MRI-image outcomes. Develop suitable metrics (e.g. SSIM; PSNR) for quality, based on fiducial images. One approach for construction of the latter will be to deliberately degrade high-quality images, which will then serve as their own gold standard for comparison. Evaluate the efficacy of the Wasserstein-2 metric in comparison with the Wasserstein-1 metric in the program described above. Level Of Effort: (0.5 x 2) graduate students, 50% effort for each of two students. Government Responsibilities: The government shall provide suitable background from the MRI Section’s previous work and expertise in machine learning and artificial intelligence developments with particular emphasis on MRI applications. The project officer will evaluate code, algorithms, and methods produced by the contractor and provide feedback at each of the stages described above. Delivery Or Deliverables: The contractor shall deliver code (e.g. Python and MATLAB scripts) generated in pursuing the program outlined above. The contractor shall provide detailed instructions on using this code so that the National Institute on Aging (NIA) researchers can reproduce their work and apply the analytical techniques developed to new data. These instructions will include both annotations within the code and separate documents providing step-by-step instructions. The contractor shall provide the results of applying the analytical techniques developed to the MRI data provided by the Government. The timely submission of deliverables is essential to successfully completing this requirement. Deliverables are to be submitted in electronic copy. Period of Performance: 10 months Capability Statement /Information Sought: Companies that believe they possess the capabilities to provide the required products or services should submit documentation of their ability to meet each of the project requirements to the Contracting Officer. The capability statement must specifically address each of the project requirements separately. Additionally, the capability statement should include 1) the total number of employees, 2) the professional qualifications of personnel as it relates to the requirements outlined, 3) any contractor GSA Schedule contracts and/or other government-wide acquisition contracts (GWACs) by which all of the requirements may be met, if applicable, and 4) any other information considered relevant to this program. Capability statements must also include the Company Name, Unique Entity ID from SAM.gov, Physical Address, and Point of Contact Information.
