Calibrated C‐arm fluoroscopy is used for a variety of medical procedures where objects and anatomical structures need to be located in space. Calibration often based on imaging grid fiducial markers using the image's geometrical measurements (radius center) together with positions markers. An on‐line technique developed automatically locate validated 97 images. The success rate detection algorithm 96.28% an average error standard deviation .
The `TALON' architecture has been proposed to meet the unprecedented processing requirements and flexibility required for Square Kilometre Array-Phase-1 (SKA1) Mid telescope, Correlator & Beamformer (Mid. CBF). high-performance hardware platform of TALON incorporates two variants line-replaceable-units (LRUs); TALON-SX TALON-MX. Each LRU features a single Intel Stratix-10 FPGA, 2 DDR4 DIMM modules, 4 100GE QSFP28 ports 48 26 Gbps bi-directional optical channels that connect custom...
We present an end-to-end model of the signal-chain correlator and beamformer Square Kilometre Array Phase 1 Mid telescope. The objective this is to determine whether proposed signal processing architecture can meet SKA's stringent requirements on quality. consists two parts: 1) "Reference" model, 2) "Realizable" model. Both are implemented in MATLAB. reference realizable models with double-precision floating point arithmetic, however, considers quantized data coefficients for algorithms....
The roll-out plan for Square Kilometer Array (Phase 1) (SKA1) Mid Frequency Telescope calls five array assemblies which progressively integrate an increasing number of receptors and capabilities. TALON Demonstration Correlator (TDC) is a small correlator / beamformer system to implement the first two SKA1 Beamformer (Mid.CBF). objective TDC design minimize amount hardware required early releases, while maximizing re-use firmware software across all assemblies. based on technology Slice...
The Square Kilometre Array (SKA) project is an ambitious international effort to build the world's largest radio telescope with unprecedented sensitivity because of its huge collecting area. SKA will be a distributed observatory telescopes at two different radio-quiet sites, SKA-MID in South Africa and SKA-LOW Australia [1]. first phase (SKA1-Mid) consist 150-kilometre diameter array 197 offset Gregorian antennas (dishes). This paper describes overview recent progress on design, test,...
The Single Pixel Feed Receiver (SPFRx) has been developed for the SKA1-Mid dishes by National Research Council (NRC) Canada in cooperation with University of Bordeaux, France. SPFRx takes preamplified SPF Radio Frequency (RF) signals two polarities and converts RF into digital samples. conditioning component RXS applies bandpass filtering, spectrum leveling, variable gain amplification to prepare sampling Analog Digital Converter (ADC) devices. ADC-produced samples are processed a processor...
