We have developed radiofrequency coils for high-field head and whole-body imaging which achieve near optimal rf field (Br) homogeneity and signal-to-noise ratio (SNR). The design, based on a lumped element delay line, has a number of advantages. The rf field uniformity is significantly better than that of a saddle coil or slotted tube resonator. The improved Br homogeneity is needed to generate...

Lipofibromatous hamartoma (LFH) is a rare fibrofatty tumor of adipocytes within peripheral nerves, affecting mainly children. It typically presents as palpable mass surrounding the nerves upper limbs, causing pain and neurological deficits in affected nerve distribution. We report case child with 2-years presentation right wrist associated paresthesia, who underwent investigation magnetic reson...

This paper presents the propagation of dual-band diamond dipole antenna on three various jackets. The jackets are purely fleece fabric with Shieldit patches top it. network analyzers flexible lossless coaxial cable used to measure communication antennas. experiment involves a man ideal body mass index (BMI) wearing by placing antennas It is observed that best on-body engineered jacket. 10 dB im...

A routine cone calorimeter procedure, the theoretical analysis method, based on a set of ignitability data from calorimeter, has been performed. The five sets ignition times at different irradiance levels were used for obtaining experimental needed analysis. tests performed with horizontal specimens size 100 mm × consisting eight pieces commercial poly(vinyl chloride) coaxial power cable. Speci...

purpose : to compare the outcomes of coaxial microincision phacoemulsification with that of conventional coaxial phacoemulsification setting: department of ophthalmology, farabi and noor eye hospitals, tehran, iran methods : in a prospective study, 74 eyes of 74 patients with cataract were randomly selected to have cataract extraction using 1 of 2 techniques: coaxial microincision phacoemulsifi...
