Gamma ray imaging is usually accomplished by the use of a relatively large scintillating crystal coupled to either number photomultipliers (PMTs) (Anger Camera) or single Position Sensitive PMT (PSPMT). Recently development new diagnostic techniques, such as scintimammography and radio-guided surgery, have highlighted significant limitations Anger camera in procedures. In this paper dedicated gamma proposed for clinical applications with aim improving image quality utilizing detectors an...
Abstract Honeydew-excreting hemipterans, such as mealybug pests, can be protected from their natural enemies by tending ants in return for honeydew, thereby compromising the aims of biological control. In this respect, antagonistic interactions between ant Tapinoma nigerrimum, native to Mediterranean basin, and main both vine (VMB), Planococcus ficus, citrus (CM), citri, were assessed laboratory conditions. Parasitism CMs respective parasitoids, Anagyrus sp. nr. pseudococci Leptomastix...
The composition of two different Origanum vulgare essential oils (EOs) was analysed by gas chromatography-flame ionization detection (GC-FID) and chromatography-mass spectrometry (GC-MS); their repellent antimicrobial effects were evaluated against adults late-instar larvae Tribolium confusum Sitophilus oryzae (Insecta: Coleoptera), Gram-negative -positive bacteria Pseudomonas fluorescens, Escherichia coli, Staphylococcus aureus, Bacillus cereus the pathogenic fungi, Penicillium digitatum...
Prone scintimammography with Tc-99m SestaMIBI has been proposed as a method of detecting breast cancers in women dense breasts. Clinical reports have shown that this technique lacks sensitivity for cancer smaller than 1 cm. To overcome some limitations offered by Auger camera on imaging was realized new scintigraphic detector dedicated to SPEM (Single Photon Emission Mammography). This novel small FOV device, shows high spatial resolution performances (<2 mm), but poorer energy values, (17%...
The YAP (yttrium aluminum perovskite) camera is a novel gamma with intrinsic submillimeter spatial resolution and detection efficiency comparable to standard Anger camera. At the first stage, it miniature field of view 4/spl times/4 cm/sup 2/ currently utilized for radio tracer studies on small animals. consists multicrystal array coupled position sensitive photomultiplier tube (Hamamatsu R2486) parallel hole collimator. preliminary results are presented discussed, in particular...
The Anger camera principle has shown a practical limit of few millimeters spatial resolution. To overcome this limit, new gamma prototype been developed, based on position-sensitive photomultiplier tube (PSPMT) coupled with scintillation crystal. Hamamatsu R2486 PSPMT is 76-mm diameter in which the electrons produced conventional bi-alkali photocathode are multiplied by proximity mesh dynodes and form charge cloud around original coordinates light photon striking photocathode. A crossed wire...
In 2009, two mealybug species Planococcus ficus (Signoret) and citri (Risso) an armoured scale species, Hemiberlesia lataniae were recorded throughout Tunisian table-grape vineyards.P. was by far the most widespread insect within investigated grape growing areas also on fig trees.Among 31 inspected vineyards, 8 non-infested, 16 slightly to moderately infested, 7 highly infested mealybugs.Therefore, latter are principal pests in vineyards should be sustainably managed avoid major crop losses...
For scintimammography (SMM) to have wide clinical use, physicians must be able rapidly direct biopsy of small cancers. The authors therefore undertook a theoretical and experimental study lesion visibility vs. acquisition time tumor size. Theoretical considerations as contrast suggested that compression would significantly improve for These predictions were confirmed with phantom studies. Patient studies showed high confidence images primary breast tumors can produced the addition...
Up today Hamamatsu R3292 is the Position Sensitive Photo Multiplier Tube (PSPMT) with largest sensitive area (10 cm of diameter). At same time it has minimum size for clinical application in Nuclear Medicine. A portable gamma camera was realized, based on 5" PSPMT coupled to a scintillating array. The head light weight (15 kg.) spatial resolution resulted better than that Anger Camera good linearity response, energy and FOV coincident intrinsic one PSPMT. To optimize response two different...
Spatial localization of radioactive sources is currently a main issue interesting different fields, including nuclear industry, homeland security as well medical imaging. It achieved using systems, but the development technologies for detecting and characterizing radiation becoming important especially in In this latter field, detection probes have long been used to guide surgery, thanks their ability localize quantify radiopharmaceutical uptake even deep tissue. Radiolabelled colloid...
Environmental factors impact and incidence of parasitism Psyllaephagus bliteus Riek (Hymenoptera Encyrtidae) on populations Glycaspis brimblecombei Moore (Hemiptera Aphalaridae) in Mediterranean climatic areas
Gamma-ray imaging is usually performed by a scintillating crystal coupled to number of PMTs (Anger camera) or single PSPMT. Detection area and spatial resolution are the most critical parameters. Nuclear medicine, as well astrophysics has need camera with detection larger than 400 cm/sup 2/, an intrinsic about 1 mm, light weight, low thickness cost. In this paper authors propose new design for large based upon array Hamamatsu R5900-C8 PSPMTs. The basic concept same Anger camera, but...
