The Safety and Biocompatibility of Platinum Iridium Markers Platinum Iridium Markers are an essential aspect of modern medical treatment, particularly in the field of radiation therapy. They serve as a reference point for accurately delivering radiation doses to cancerous cells. ...
Respectivetumor volumes were 2.60 and 4.02 cm3. A radiation dose of 13 Gy was prescribed to the50% isodose line. At 8 mo of follow-up, preoperative symptoms were either resolved orstable and MRI imaging demonstrated a 31% and 56% reduction in lesion volume, respec-tively. ...
Comparative visualization of the left renal artery with the IOPS platform (left) versus fluoroscopy and contrast dye (right).Study essentials In fact, radiation dose is one of the main measures being assessed in the MOTION trial, along with use of contrast dye and duration of the EVAR procedure. ...
Adjuvant radiation is used either alone or in combination with chemotherapy, and the most common method of radiation treatment is external beam radiation therapy (EBRT).1,2 For EBRT, a large machine generates radiation beams and focuses them inward to travel through the skin, then through the skull, and finally, into the brain.2 ...
Adler, CEO of ZAP Surgical Systems, and professor emeritus of neurosurgery and radiation oncology at Stanford University. “With ZAP-X, patients can be treated without the potential complications and recovery of a surgical procedure.” The new ZAP-X technology is recognized for using gyroscopic motion to direct radiosurgical beams from hundreds of unique angles to ...
VeraForm continues to yield exceptional results for our planning radiation therapy (XRT) efforts with the radiation oncology team. Building on that success, we recently integrated VeraForm into our APBI program with the SAVI® brachytherapy catheter system. ...
These complex procedures have required increased fluoroscopy times, resulting in higher radiation dose exposure to both patients and operators. It has also necessitated the development and use of an increased number of various-shaped catheters, sheaths, and wires to cannulate target vessels. In addition, it has led to an increase in the amount of contrast ...
The mechanical error at the Sydney plant sent hospitals throughout Australia and Southeast Asia scrambling to cover more than 10,000 doses a day, or about 8% of the worldwide demand. US Nuclear Corporation (OTC PINK: UCLE) and MIFTEC industries, with their Z-pinch fusion technique have a revolutionary new solution addressing the global shortage and problematic supply chain of ...
The aim of the study is to assess the health status of Kozloduy Nuclear Power Plant personnel in association with their occupational exposure to low doses of ionising radiation (IR) as well as with other factors of their working environment and to determine the probability of the occupational exposure to be a reason for the diagnosed malignant diseases ...
Several studies have revealed that interventional radiography procedures performed in cardiology departments are high dose techniques. In this study, effective dose of cardiologists working in hospitals Catheterisation Laboratories (CATHLABs) in Mashhad city have been measured during Coronary Angiography (CA) and Percutaneous Transluminal Coronary Angioplasty ...
However, although the application of this equipment in the national security area is indeed relevant, its use has caused a great deal of controversy, especially with regard to the doses absorbed and to the cancer induction risk associated with these exposures. The aim of this study is to use the Monte Carlo MCNPX code and the male adult voxel (MAX) and female adult voxel (FAX) ...
Twenty percent of cancer patients experience adverse effects after radiotherapy. The therapeutic doses are adjusted to the most sensitive individuals, resulting in a suboptimal dose for many patients. ...
Peripheral blood lymphocytes of apparently healthy donors were exposed to low-dose ionising radiation and/or human-genome CpG-DNA fragments accumulating in total extracellular DNA. ...
This study was designed to investigate the clinical significance of low-dose radiation therapy, radiation hormesis, and accuracy of therapeutic regimen. ...
Simulation for the Bragg peak calculation was performed for interactions with a human organ, the pancreas. The results show the absorbed dose and dose equivalent, which vary with the energy of ion beams. This work can give us the theoretical feasibility of constructing a heavy ion accelerator for practical purpose. ...
Many radiation workers believe that occupational exposures have the potential to interfere with their normal reproductive function. In this study, a total of 621 radiation workers (336 females and 285 males) who worked in hospitals/clinics in seven different provinces were randomly selected. ...
It is important to avoid conditions where the amount of radiation used is more than that needed for the procedure. The purpose of this work is to use the Monte Carlo code MCNPX and the Female Adult voxel (FAX) and Male Adult voxel (MAX) phantoms to investigate how the effective doses, absorbed doses to organs and risk of cancer incidence vary for ...
Tissue inhomogeneity and organ geometry were also taken into account. The Dose Point Kernel (DPK) method was used to calculate the absorbed dose in target and source organs. ...
Population exposure to diagnostic and therapeutic ionising radiation is likely to increase worldwide, and this has raised concerns about the stochastic effects of low doses of radiation exposure. The present study was aimed to study the incidence of Chromosomal Aberrations (CAs) in patients exposed to low doses of X-rays during ...
The most emotionally gripping topic of the debate over expansion of commercial nuclear power in the USA centres on the threat of radiological harm to the public from a commercial nuclear power plant accident. The perseverance of the radiation fear issue is reviewed herein, followed by summarisation of the expanded knowledge of reactor safety over the last 30 years. Analyses of ...
