Image nois. analys.s.of a large ring PET s.anner “macro PET” performed us.ng two different phantoms. namely a Jas.czak s.ECT phantom and a uniform cylindrical phantom. In the pres.nt work, s.mple 2D filtered back projection was.us.d to recons.ruct all the images. and in almos. all the cas.s.a Hamming filter of cutoff frequency 0.4 and a 256 by 256 matrix with zoom factors.from 1 to 4 were us.d in order to inves.igate the imaging capabilities.of the new s.anner and the influence of filter and cut-off frequency on the filtered back projected images. Res.lts.indicate that 11.1 mm cold rod in the Jas.czak phantom images.can cons.s.ently be s.en. The Coefficient of variation (CV) res.lts.for Hann and Hamming filters.are very s.milar and increas. approximately in linear fas.ion with higher cutoff frequency. The value of CV for the Pars.n filter is.lower than the value for Hann and Hamming filters.

We dis.us. a quantum remote s.ate preparation protocol by which two parties. Alice and Candy, prepare a s.ngle-qubit and a two-qubit s.ate, res.ectively, at the s.te of the receiver Bob. The s.ngle-qubit s.ate is.known to Alice while the two-qubit s.ate which is.a non-maximally entangled Bell s.ate is.known to Candy. The three parties.are connected through a s.ngle entangled s.ate which acts.as.a quantum channel. We firs. des.ribe the protocol in the ideal cas. when the entangled channel under us. is.in a pure s.ate. After that, we cons.der the effect of amplitude damping(AD) nois. on the quantum channel and des.ribe the protocol executed through the nois. channel. The decrement of the fidelity is.s.own to occur with the increment in the nois. parameter. This.is.s.own by numerical computation in s.ecific examples.of the s.ates.to be created. Finally, we s.ow that it is.pos.ible to maintain the label of fidelity to s.me extent and hence to decreas. the effect of nois. by the application of weak and revers.l meas.rements. We als. pres.nt a s.heme for the generation of the five-qubit entangled res.urce which we require as.a quantum channel. The generation s.heme is.run on the IBMQ platform.

High res.lution (4 mm) tof PET-CT (pos.tron emis.ion tomography-computed tomography) from Philips.of model Ingenuity TF is.newly ins.alled at Ins.itute of Nuclear Medical Phys.cs.(INMP). 128 s.ice CT component incorporated with PET provides.comparatively lower dos. than the 511 keV annihilation photons.as.ociated with pos.tron decay from PET s.an. s., for des.gning s.ielding in our PET-CT facility, only 511 keV annihilation photons.energy has.been cons.dered. The main objective of this.paper is.to s.ow what meas.res.have been taken to protect patients. occupational workers.as.well as.environment from PET-CT radiation hazard through a cos. effective des.gn that s.tis.y the national regulatory demand. In this.paper, AAPM (American As.ociations.of Phys.cis.s.in Medicine) Tas. group 108 analys.s.for PET and PET-CT s.ielding requirements.is.followed for our PET-CT facility s.ielding des.gn. From theoretical calculation as.s.ielding requirement, 1.1 cm Pb thicknes. or, 13 cm concrete thicknes.es.are found. Practically, all walls.and ceiling are of 30.48 cm (1 foot) thick made of concrete with dens.ty 2.35 gcm-3 for more s.fety. As.x-ray from CT is.not taken into account for s.ielding analys.s.

The lipid profile remains.an important laboratory as.es.ment to prevent cardiovas.ular dis.as.. Interpretation of the non-fas.ing lipid profile has.s.gnificantly changed bas.d on new information concerning the pathogenes.s.of atheros.leros.s. In particular, the as.es.ment of ris. from choles.erol containing particles.following triglyceride metabolis. (termed remnant choles.erol) can now be done from a lipid profile. In addition, non-HDL choles.erol as.calculated from the lipid profile will provide a complete as.es.ment of total circulating choles.erol containing particles. Furthermore, the formula for meas.rement of LDL choles.erol from a lipid profile has.now been revis.d s. that triglyceride levels.exert les. interference. Finally, the old concept that the “higher the HDL-c, the better” is.no longer tenable. New data indicate that the optimal high dens.ty lipoprotein level is.below 100 mg/dl for both male and female patients. Correct interpretation of the lipid profile will optimize anti-atheros.lerotic therapy and reduce the number one caus. of death in the United s.ates.
