introduction wedge modifiers are commonly applied in external beam radiotherapy to change the dose distribution corresponding to the body contour and to obtain a uniform dose distribution within the target volume. since the radiation dose delivered to the target must be within ±5% of the prescribed dose, accurate dose calculation by a treatment planning system (tps) is important. the objective ...

Optical rulers have served as a key tool for scientists from different disciplines to address a wide range of biological activity. Since the optical window of state of the art FRET rulers is limited to a 10 nm distance, developing long range optical rulers is very important to monitor real life biological processes. Driven by this need, the current manuscript reports for the first time the desi...

We implanted a Medtronic Micra Transcatheter Pacing System (TPS) using standard technique, but after cutting the tether, a slight resistance was felt when the tether was pulled back. Subsequently, the electrical properties of the system were unacceptable. In order to retrieve the TPS, a 3 F snare with a 10–25 mm loop can be loaded into the delivery system. However, this snare was not available....

Adventitious root cultures were developed from Tripterygium regelii, and growth conditions were optimized for the abundant production of diterpenoids, which can be collected directly from the medium. An analysis of publicly available transcriptome data sets collected with T. regelii roots and root cultures indicated the presence of a large gene family (with 20 members) for terpene synthases (TP...

This paper provides a comparison of spline-based registration methods applied to register interventional Trans Rectal Ultrasound (TRUS) and pre-acquired Magnetic Resonance (MR) prostate images for needle guided prostate biopsy. B-splines and Thin-plate Splines (TPS) are the most prevalent spline-based approaches to achieve deformable registration. Pertaining to the strategic selection of corres...

Theta burst stimulation (TBS) produces an extremely stable form of long-term potentiation (LTP). In contrast, a brief episode of single-pulse stimulation at theta frequency [theta pulse stimulation (TPS)] has been demonstrated to reverse LTP in area CA1 of slices and freely moving animals without causing depression when administered to nonpotentiated pathways. The present in vitro studies confi...

Abstract Introduction: In vivo dosimetry verification is currently a necessity in radiotherapy centres Europe countries as one of the tools for patient-specific QA, and now its demand rising developed countries, such Malaysia. The aim this study to characterize commercial EPID-based implementation treatment Materials Methods: work, sensitivity performance commercially available system, EPIgray®...

Objective A Comparatively study of effectiveness and safety of traditional pterional surgery (TPS) and endoscopic endonasal trans-sphenoidal suirgery (EETS) for resection of Tuberculum sellae meningioma using visual and gross total resection as outcome measures. Methods A PUBMED and MEDLINE (2002-2014) search were performed to identify the series for tuberculum sellae meningioma (TSM) resected...

In radiotherapy treatment portal images and digitally reconstructed radiographs (DRRs) are the most frequently used image-guidance systems to monitor patient set-up during clinical routine. DRR is therefore a critical element in the process of virtual simulation and patient position verification in radiotherapy. The aim of this work was to assess the geometric reliability of the DRR generated b...
