Tomographic breast imaging techniques can potentially improve detection and diagnosis of cancer in women with radiodense and/or fibrocystic breasts. We have developed a high-resolution positron emission mammography/tomography biopsy device (called PEM/PET) to detect guide the suspicious lesions. PET images are acquired focal uptake radiotracer area. Limited-angle PEM could then be used verify needle position prior tissue sampling. The PEM/PET scanner consists two sets rotating planar...
Observations made in April 2013 of the radioxenon isotopes (133)Xe and (131m)Xe at measurement stations Japan Russia, belonging to International Monitoring System for verification Comprehensive Nuclear-Test-Ban Treaty, are unique with respect history these stations. Comparison measured data calculated isotopic ratios as well analysis using atmospheric transport modeling indicate that it is likely xenon was created underground nuclear test conducted by North Korea on February 12, 2013,...
Multi-modality imaging is rapidly becoming a valuable tool in the diagnosis of disease and development new drugs. Functional images produced with PET fused anatomical structure created by MRI will allow correlation form function. Our group developing system to acquire contemporaneously. The prototype device consists two opposed detector heads, operating coincidence mode. Each MRI–PET module an array LSO elements coupled through long fibre optic light guide single Hamamatsu flat panel...
Results are presented on the optimization of design and use dedicated compact scintimammography gamma cameras. Prototype imagers with a field view (FOV) 5/spl times/5 cm/sup 2/, 10/spl times/10 2/ 15/spl times/20 were used in either dual modality mode as an adjunct technique to digital X-ray mammography or stand-alone instruments such breast SPECT planar imagers. Experimental data acquired select best imaging (SPECT planar) detect small lesions using Tc/sup 99m/ radio-labeled...
Recent technological advances have facilitated the widespread use of sensor networks in many applications. In particular, deploying sensors a workspace provides valuable alternative to on-board localisation for mobile robots. Coverage and placement problems which jointly estimate states targets received considerable attention recently. this paper, we consider problem triangulation-based localisation. The is non-deterministic polynomial-time hard its most general form. We present...
Positron emission mammography (PEM) is a new, specialized imaging modality utilizing PET radiopharmaceuticals to detect breast cancer. The capabilities and limitations of PEM in detecting tumors were investigated with series phantom experiments. imager was mounted on standard Lorad biopsy table (separated by 18 cm). In the initial phase investigation, basic scanner parameters (resolution, sensitivity, scatter fraction) measured. effects number (length acquisition, thickness, density)...
We have developed economical readout concept for multianode photomultiplier tubes which a matrix type pad anode layout. This style of layout is used in many position sensitive such as R5900-M64 and recently available flat panel H8500 PMT from Hamamatsu Photonics, well the Burle PLANACO/spl trade/ 85011 PSPMT. All these PMTs 8/spl times/8 pads requiring signal 64 outputs. The number channels quickly increases systems utilizing PMTs. In order to reduce active be read we employed...
