Algorithm validation using multicolor phantoms
We present a framework for hyperspectral image (HSI) analysis validation, specifically abundance fraction estimation based on HSI measurements of water soluble dye mixtures printed on microarray chips. In our work we focus on the performance of two algorithms, the Least Absolute Shrinkage and Selection Operator (LASSO) and the Spatial LASSO (SPLASSO). The LASSO is a well known statistical metho...
متن کاملExperimental Validation of the Spectral Fit Algorithm Using Tissue Mimicking Phantoms
Characterizing tissue by measuring its physical properties has potential for improving the diagnostic capabilities of medical ultrasound. One parameter that is estimated using the power spectrum of backscattered ultrasound echoes is the characteristic size or correlation length of the tissue microstructure responsible for the scattering. Unfortunately, the characteristic size measurement has tr...
متن کاملValidation of near infrared spectroscopic (NIRS) imaging using programmable phantoms
For much of the past decade, we have developed most of the essential hardware and software components needed for practical implementation of dynamic NIRS imaging. Until recently, however, these efforts have been hampered by the lack of calibrating phantoms whose dynamics substantially mimic those seen in tissue. Here we present findings that document the performance of a dynamic phantom based o...
متن کاملDigital perfusion phantoms for visual perfusion validation.
OBJECTIVE Despite the increasingly broad use of perfusion applications, we still have no generally accessible means for their verification: The common sense of perfusion maps and "bona fides" of perfusion software vendors remain the only grounds for acceptance. Thus, perfusion applications are one of a very few clinical tools considerably lacking practical objective hands-on validation. MATER...
متن کاملDesigning microarray phantoms for hyperspectral imaging validation
The design and fabrication of custom-tailored microarrays for use as phantoms in the characterization of hyperspectral imaging systems is described. Corresponding analysis methods for biologically relevant samples are also discussed. An image-based phantom design was used to program a microarrayer robot to print prescribed mixtures of dyes onto microscope slides. The resulting arrays were image...
