Virtual monochromatic images (VMI) that reconstructed on dual-energy computed tomography (DECT) have actually further application prospects in radiotherapy, and there is nevertheless a lack of clinical dosage confirmation. In this study, GE Revolution CT scanner was utilized to perform standard imaging and gemstone spectral imaging regarding the simulated head and the body phantom. The CT photos were imported to radiotherapy treatment planning system (TPS), and the exact same treatment plans had been transplanted to compare the CT worth plus the PTC-028 molecular weight dosage distribution. The results reveal that the VMI can be imported into TPS for CT value-relative electron density transformation and dosage calculation. In comparison to old-fashioned images, the VMI differs from 70 to 140 keV, has actually small difference in dose distribution of 6 MV photon therapy plan.The automatic analysis purpose of the electrocardiograph (ECG) machine straight impacts the clinical application for the device. But, there is certainly presently no unified criteria when it comes to analysis of this automated analysis function of the 12-lead ECG machine in center. We established a 12-lead ECG automatic diagnostic purpose clinical analysis specification from the range associated with specification, the automatic diagnostic purpose wisdom principles, general technical dimension requirements, test practices and problems, and ECG data-input. Focus is provided to the judgment guidelines of this automated analysis purpose, like the reliability of ECG function values, the explanation and wisdom of automated diagnosis results. This requirements is designed to offer technical foundation when it comes to medical evaluation for automated analysis function of the 12-lead ECG.This article introduces the safety risks associated with book light-based home-use tresses elimination device, and analyzes the distinctions in legislation among China, the United States as well as the European Union. In China, family extreme pulsed light locks reduction products will additionally be monitored in respect with health unit regulations. Therefore, the safety criteria used when you look at the absence of certain laws are no longer relevant to the new regulating needs. Its vital to adopt the latest standards available to home photoepilators, to be able to make sure the security and effectiveness associated with the approved devices.In purchase to aid the IVD medical equipment manufacturers to determine the solution lifetime of services and products scientifically, we study the main aspects which could impact the solution life of IVD health equipment prior to the leading concepts for technical overview of active health devices given by the center of medical device analysis of NMPA, and focuse on an assessment way of accelerated tiredness test, so that you can standardize and guide the IVD medical equipment manufacturers to evaluate and formulate the merchandise solution life scientifically. Under acid conditions, β-lactoglobulin is hydrolyzed into free proteins, separated by cation trade chromatography, and derivatived after ninhydrin column. The chromatogram at 570 nm is collected. The content of β-lactoglobulin in the sample is ultimately decided by measuring the lysine content acquired by hydrolysis. To analyze the safety of alginate based gastric mucosal defensive glue and its feasibility as a submucosal shot. gastric mucosal uplift test in pigs as well as in vivo gastric mucosal uplift test in rats. The security of alginate based gastric mucosa defensive glue was examined biotic and abiotic stresses by cytotoxicity test, intense poisoning ensure that you oral mucosa stimulation test according to GB/T 16886 series standard of biological evaluation of medical self medication devices. <0.05). Gastric mucosal defense glue doesn’t have cytotoxic dental mucosal discomfort or intense toxicity. Gastric mucosa protector is a promising brand new medical device product with feasibility and great biocompatibility as submucosal uplift injection agent.Gastric mucosa protector is a promising brand-new health unit product with feasibility and good biocompatibility as submucosal uplift injection agent.In modern times, with all the large application of magnetic resonance imaging (MRI) equipment in medical rehearse, the caliber of the apparatus triggers undesirable activities, which place pressure on makers, at precisely the same time, it sets forward greater demands for health unit supervisors. To be able to help the medical device supervisors to make clear the important thing things of confirmation, this paper analyzes the primary threat points within the production procedure for the item based on the health device great manufacturing practice(GMP), and leaves forward the suggestions for field verification, which includes practical relevance when it comes to submission of verification efficiency.With the popularization of angiography and improved checking in Asia, ruthless contrast injector is widely used in CT, MRI, DSI and so on, the writers team try to explore and consider the harmfulness and countermeasures regarding the reuse of this throwaway high-pressure comparison injector from the viewpoint of medical device guidance.
