Intrinsic flood field uniformity is a fundamental quality control test that is considered as prerequisite for performing clinical routine exams using the gamma camera. Every gamma camera vendor provides recommended geometrical and physical parameters that should be followed while performing this test. Conventional methods using NEMA recommended parameters also can be used as well. The aim of th...

introduction:surgeosight is a dedicated intra-operative hand-held gamma camera designed and manufactured by our team to be used for lymphoscintigraphy. although conventional gamma cameras are widely used, they lack the capability of the sentinel lymph node (sln) imaging in the operation room. like conventional gamma cameras it is necessary to calibrate surgeosight for linearity distortion, ener...

Botulinum toxin is probably the newest addition in the treatment armamentarium for overactive bladder , but, despite its late FDA approval, a significant experience exists in several centers around the world with this type of treatment. Because of its experimental status, the treatment with botulinum toxin is still lacking the much needed standardization, allowing for a great variety when it co...

Introduction L-asparaginase is an essential chemotherapeutic agent in the therapy of acute lymphoblastic leukemia (ALL), which has led to improvement survival. In low- and middle-income countries like India, outcomes ALL are inferior compared with published literature, one causes believed be due quality bioequivalent asparaginase. Objective The following survey attempts understand practice usin...

In the context of multicriteria decision making whose aggregation process is based on the Choquet integral, bi-capacities can be regarded as a natural extension of capacities when the underlying evaluation scale is bipolar. The notion of entropy, recently generalized to capacities to measure their uniformity, is now extended to bi-capacities. We show that the resulting entropy measure has a ver...

The present study was performed to optimize a superovulation protocol in rats in order to produce a large number of good-quality embryos suitable to develop rat embryonic stem (rES) cells. We first evaluated the ovulation kinetics of three rat strains: Wistar, Fisher and ACI/N. Animals (n=30 per strain) were treated with 50 IU of pregnant mare serum gonadotrophin (PMSG), and ovulation was induc...

Some scintillation camera manufactures adhere to standard code of performance specification established by National Electric Manufactures Association (NEMA). Items such as differential and integral uniformity, spatial resolution energy resolution, etc. are all calculated with reproducible methodology that allows the user reliable technique for creation of these standards to avoid any lack of cl...

When testing that a sample of n points in the unit hypercube [0, 1] comes from a uniform distribution, the Kolmogorov–Smirnov and the Cramér–von Mises statistics are simple and well-known procedures. To encompass these measures of uniformity, Hickernell introduced the so-called generalized Lp-discrepancies. These discrepancies can be used in numerical integration through Monte Carlo and quasi–M...
