BACKGROUND To explore the interobserver variability in the delineation of the tumour bed using seroma and surgical clips based on the four-dimensional computed tomography (4DCT) scan for external-beam partial breast irradiation (EB-PBI) during free breathing. METHODS Patients with a seroma clarity score (SCS) 3 ~ 5 and ≥5 surgical clips in the lumpectomy cavity after breast-conserving surgery...

in this paper, the stability of a functionally graded magneto-electro-elastic (fg-mee) micro-beam under actuation of electrostatic pressure is studied. for this purpose euler-bernoulli beam theory and constitutive relations for magneto-electro-elastic (mee) materials have been used. we have supposed that material properties vary exponentially along the thickness direction of the micro-beam. gov...

Bed bug (Cimex lectularius L.) infestations are currently controlled by a variety of non-chemical and chemical methods. There have been few studies on the comparative effectiveness of these control techniques. We evaluated three bed bug management strategies in an apartment building: (1) non-chemical methods only (n = 9); (2) insecticides only (n = 6); and (3) integrated pest management includi...

BACKGROUND The authors conducted this prospective study to analyze the amount of interfractional prostate bed motion (PBM) and quantify its components with the use of an endorectal balloon (ERB). METHODS A total of 1,348 cone beam computed tomography images from 46 patients who underwent postprostatectomy radiotherapy were analyzed. For the pilot image, electronic portal imaging, guided by sk...

background : during the last 3 decades, there were increasing tendency towards angioplasty because of its benefits. but, this procedure has its acute problems like bleeding and formation of hematoma in the removal place of the sheet. based on researchers’ clinical experiences, patients need a time of 8-12 hours for bed rest after coronary angioplasty. recognizing desirable time for bed rest aft...

LLE Review, Volume 127 113 Beam-shaping applications in high-power laser systems have been presented in many different contexts such as the improvement of laser performance1 or the manipulation of laser–target interactions.2,3 These applications commonly employ static apodizers or deformable mirrors. Spatial-light modulators (SLM’s) are also popular beam-shaping devices. Because of their low da...

More and more anaesthetists are getting involved in interventional radiology procedures and so it is important to know the radiation dose and to optimise protection for anaesthetists. In this study, based on Monte Carlo simulations and field measurements, both the whole-body doses and eye lens dose of anaesthetists were studied. The results showed that the radiation exposure to anaesthetists no...

A near-infrared camera (NIR) is employed to monitor layer-by-layer in-situ electron beam powder bed fusion (E-PBF). We aim at demonstrating that such a device allows various kinds of flaws be reliably captured thanks qualitative thermal information. Defects as distortions or uneven top surfaces can detected in the NIR-images. Information about temperature heterogeneities also linked with some o...
