OBJECTIVES: To apply the economic terminology of lean manufacturing and the Toyota Production System to the procurement of vascular stents in interventional radiology. METHODS: The economic- and process-driven terminology of lean manufacturing and the Toyota Production System is first presented, including information and product flow as well as value stream mapping (VSM), and then applied to a...

Lean principles were originally developed in industrial operations as a set of tools and practices that managers and workers could use to eliminate waste and inefficiency from production systems—reducing costs, improving quality and reliability, and speeding up cycle times. Toyota Motor pioneered lean practices, and much of their allure today stems from the fact that the phenomenal performance ...

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....

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 ...

A dose calculation verification system (VS) was acquired and commissioned as a second check on the treatment planning system (TPS). This system reads DICOM CT datasets, RT plans, RT structures, and RT dose from the TPS and automatically, using its own collapsed cone superposition/convolution algorithm, computes dose on the same CT dataset. The system was commissioned by extracting basic beam pa...

Therapeutic peptides (TPs) are a class of peptide-based agents capable of eliciting a therapeutic response by modulation of targets within or on the surface of cells. TPs are advantageous because they are amenable to rational design, they have high specificity for their targets and can be made to target almost any protein of interest, including proteins for which we have no small-molecule drugs...

Telecobalt machine is one of the essential equipment needed in many cancer centers and still prominently used for the treatment of a variety of cancer cases in developing countries. This study aims to evaluate the impact of tissue heterogeneity corrections on 3D treatment planning system (Prowess). The human body contains a variety of tissues and cavities which vary widely in their physical and...

We investigated the effect of cultivation system (conventional or organic), cooking method, and flesh color on the contents of ascorbic acid (AA) and total phenolics (TPs), and on total antioxidant activity (Trolox equivalents, TE) in Solanum tuberosum (potato) tubers. The research material, consisting of 4 potato cultivars, was grown in experimental fields, using organic and conventional syste...

Trehalose is the major blood sugar in insects. Physiological significance of this compound has been extensively reported. Trehalose-6-phosphate synthase (TPS) is an important enzyme in the trehalose biosynthesis pathway. Full-length cDNAs of TPS (Of tps) and its alternative splicing isoform (Of tps_isoformI) were cloned from the Asian corn borer (ACB), Ostrinia furnacalis (Guenée; Lepidoptera: ...
