The Large Area Sensor (LAS) is a 1350 times1350 array of active pixels on a 40 Im pitch fabricated in a 0.35 im CMOS process. Stitching technology is employed to achieve an area of 5.4 cm times5.4 cm. The sensor includes 'regions of reset', whereby three different integration times can be set on the array to achieve a large imaging range for static scenes.(More)
Objects of various shapes, with some appreciable hydrogen content, were exposed to fast neutrons from a D-T generator, resulting in a partially-moderated spectrum of backscattered neutrons. The thermal component of the backscatter was used to form images of the objects by means of a coded-aperture thermal-neutron imaging system. Timing signals from the(More)
BACKGROUND Moisture chambers are prosthetic devices coupled to eyeglasses that slow the evaporation of the tears from the ocular surface. The need for moisture chamber glasses is most evident when a patient suffers from Sjögren's syndrome. This disease creates a pathologically dry eye from tear anomalies. Other ocular and systemic conditions can also cause(More)
Image registration accuracy was<2mm for all anatomic head and neck landmark displacements in the x, y and z direction relative to CT. Image quality was found to be comparable to the commissioning benchmark. SNR data for T1 FSE and T2 FSE were not statically significantly different (p= 0.53, 0.10) from benchmark dataset. However, the benchmark configuration(More)
A Startracker CMOS monolithic active pixel sensor with 525times525 pixels each 25 microns/side has been coupled via a fibre optic stud to a CsI(Tl) crystal 2mm times 20mm times 20mm to form a test detector of gamma rays of energy between 60 keV and 200 keV. The crystal is segmented into 400 micron elements separated by 100 microns of filler. The system(More)
