The Limited Angle Problem in Computerized Tomography [PDF]
, 1984 Fast reconstruction formulae in x-ray computerized tomography demand the directions, in which the measurements are taken, to be equally distributed over the whole circle. In many applications data can only be provided in a restricted range.

Advanced Functional Materials, EarlyView.A soft, dual‐channel hydrogel patch enables simultaneous detection of wound temperature and strain by integrating ion‐diffusion‐mediated thermoelectric and resistive sensing. The conformal design maintains stable performance during motion, capturing subtle inflammatory and mechanical changes for continuous wound monitoring.

CT features of primary brain lymphoma, Tehran Shohada Hospital, 1990-2000
Majallah-i Dānishgāh-i ̒Ulūm-i Pizishkī-i Bābul, 2002 Background and Objective: Primary brain lymphoma (PBL) is one of the malignant and rare cerebral tumors and it has considerably increased over recent years because of immunosuppression such as tissue transplant and patients with AIDS. The purpose of this

Drusen in the optic nerve head. Verification by computerized tomography
, 1978 Five patients with a clinical diagnosis of buried or exposed drusen of the optic nerve head were examined by computerized tomography (CT). The relative x-ray absorption within their nerve heads was significantly larger than in controls, reflecting the ...

Advanced Functional Materials, EarlyView.Significant nanoscale oxygen diffusion coefficient variations are measured in ferroelectric hafnium zirconium oxide films with grain boundaries and electrode interfaces exhibiting values 104 times larger than the grain cores. Overall coefficients are 10X larger for films prepared with metal nitride electrodes compared to refractory metals. New insights

Historical Foundation and Practical Guideline for Ferroelectric Switching Kinetic Studies
Advanced Functional Materials, EarlyView.The P and U pulses in the conventional PUND measurements are not identical because of the interplay between switching current and the measurement circuit components. This circuit effect can lead to a shift in polarization transients and misinterpreted physics in the switching kinetics.
