Microfluidic devices are oftenly used to calibrate the imaging reconstruction, because they simulate the morphology of microvasculature. However, for lack of optical properties in microfluidics, the functional recovery of oximetry information cannot be verified. In this work, we describe the fabrication of a novel turbid optofluidic tissue phantom. It is designed to mimic the vascular perfusion...

OBJECTIVE: To compare data regarding dosimetry and photons fluence in different breast phantoms, discussing constancy tests and dosimetry applied to mammography. MATERIALS AND METHODS: Different homogeneous breast phantoms and one anthropomorphic voxel phantom were developed for collection of data regarding total absorbed dose in the phantom, absorbed dose in the glandular tissue material-equiv...

A microelectromechanical systems (MEMS)-based photoacoustic imaging system is reported for the first time. In this system, the MEMS-based light scanning subsystem and a ring-shaped polyvinylidene fluoride (PVDF) transducer are integrated into a miniaturized probe that is capable of three-dimensional (3D) photoacoustic imaging. It is demonstrated that the imaging system is able to image small ob...

A dual-band bio-implantable compact antenna with a meander-line structure is presented. The proposed resonates at the industrial, scientific, and medical (2.4 GHz) wireless telemetry (1.4 bands. selected as radiating patch given its versatile effective design. With dimension of only 10 mm × 0.635 $$ 10\ \mathrm{mm}\times 0.635\ \mathrm{mm} , designed compact. Considering skin phantom, was desig...

Abstract Skin brachytherapy is a successful practice for treating skin cancer patients. Although gamma source like an Iridium-192 (Ir-192) commonly used in the brachytherapy, use of beta Yttrium-90 (Y-90) has also been investigated this purpose. In current study, we simulated dose distribution proposed Y-90 applicator and Ir-192 Leipzig phantom, compared performance each methods three tumors hy...

background: the heterogeneous composition of the human body presents numerous tissue types and cavities with widely differing radiologic properties. the aim of the present work was to develop a low cost homogeneous and heterogeneous phantom and the absorbed dose were measured by ionization chamber for different radiotherapy treatment techniques and compared with treatment planning system absorb...

background long-term clinical symptoms and functional status of above-knee amputees are not well documented. this study documents the long-term outcomes of war related above-knee amputations. objective to study the long-term outcomes of unilateral above-knee amputation. materials and methods the study consisted of a comprehensive assessment, examination, and review of history and wartime medica...
