Query: Pattern-matching Unit for Medical Applications   We explore the application of concepts developed in High Energy Physics (HEP)
for advanced medical data analysis.
  Our study case is a problem with high social impact: clinically-feasible
Magnetic Resonance Fingerprinting (MRF). MRF is a new, quantitative, imaging
technique that replaces multiple qualitative Magnetic Resonance Imaging (MRI)
exams with a single, reproducible measurement for increased sensitivity and
efficiency. A fast acquisition is followed by a pattern matching (PM) task,
where signal responses are matched to entries from a dictionary of simulated,
physically-feasible responses, yielding multiple tissue parameters
simultaneously. Each pixel signal response in the volume is compared through
scalar products with all dictionary entries to choose the best measurement
reproduction. MRF is limited by the PM processing time, which scales
exponentially with the dictionary dimensionality, i.e. with the number of
tissue parameters to be reconstructed. We developed for HEP a powerful,
compact, embedded system, optimized for extremely fast PM. This system executes
real-time tracking for online event selection in the HEP experiments,
exploiting maximum parallelism and pipelining. Track reconstruction is executed
in two steps. The Associative Memory (AM) ASIC first implements a PM algorithm
by recognizing track candidates at low resolution. The second step, which is
implemented into FPGAs (Field Programmable Gate Arrays), refines the AM output
finding the track parameters at full resolution.
  We propose to use this system to perform MRF, to achieve clinically
reasonable reconstruction time. This paper proposes an adaptation of the HEP
system for medical imaging and shows some preliminary results.
