Xidex and The University of Texas at Austin have successfully demonstrated the feasibility of developing a magnetic resonance force microscope for single proton imaging. Our Phase II work will demonstrate use of high-precision, high-sensitivitymeasurement of the magnetic force using (a) the high-Q mode of multiple torsional oscillators fabricated from single crystal silicon as the sensing element ...

Compensation of thermal blooming and high scintillation affects requires simultaneous large amplitude and large bandwidth operation or high gain bandwidth. Present deformable mirror technology, provides 3 to 4 microns stroke with a full amplitude bandwidthapproaching 500-Hz. It has been a design criteria that as the bandwidth increased, the amplitude decreased specific to a power spectral density ...

We propose the Integrated Large-Aperture Zonal Meniscus as an evolutionary advance that will form the basis for our revolutionary Photonex Telescope vision. It features a continuous meniscus mirror with integrated zonal actuation intended for space-based, large mirror applications where weight, reliability, schedule and cost are prime factors in the design. The integrated design is directly applic ...

NASA¿s Origin Program strategic plans call for direct imaging optical telescopes to evolve from 8 to 30 to 100 meter apertures by 2025. Indirect measurements using long baseline interferometers require Angstrom level precision for long durations. High data rate communications for spatial acquisition and tracking systems require active mirrors and up-down transmission compensation. Fundamental t ...

The Proposed Phase II SBIR will develop and demonstrate an innovative approach to produce ultra-lightweight, active, segmented primary mirrors for beam directors and imaging telescopes. Named the Integrated Zonal Meniscus Mirror, it combines thedesireable materials properties of a silicon carbide substrate with electroactive actuators and sensors, and application specific integrated circuits imbe ...

DESCRIPTION (Provided by Applicant): The feasibility of continuous and economical microfabrication of timed-bioresorbable glass microspheres containing yttrium-90 (Y-90) at therapeutic concentrations has been successfully demonstrated using Y-89 surrogate in the Phase I research. The microspheres are uniform in size and chemistry, and the time ...

It is well known that scattered X-rays significantly degrade image contrast in mammography. As a result commercially available mammography units all employ low ratio grids to reduce the effects of scatter and image contrast. However, conventional mammography grids are limited in their ability to control scatter, particularly for thick dense breasts, and marked improvement in image contrast is poss ...

DESCRIPTION (provided by applicant): Bedside radiography is an area of x-ray imaging in which there is no commercially viable means of controlling scattered radiation. This is due to the difficulty in aligning the focal spot with an anti-scatter grid. X-ray scatter therefore often reduces the contrast in bedside radiographs by a factor of 10 or more. This problem is exacerbated in digital imagi ...
