Radiology is a critical component of most medical care. As a consequence of this, legal cases in which individuals are claiming injuries will frequently have imaging studies as a central aspect of the record. Demonstrative evidence can be used as an important instrument in helping to lay the proper foundation for creating a compelling and memorable argument in the presentation of a legal case
Inadequate research exists regarding testing of a ventricular assist device (VAD) for susceptibility to radiation damage. Specifically, minimal data are available to radiation oncologists prescribing treatment plans for patients with an implanted VAD. As the number of implanted devices increases, patients requiring radiation at tissue sites near or at the device will increase.
New research shows the effects of electron beams on implanted vascular access ports composed of plastic, determining how they impair the fluence of radiation around them.
Abstract. Object: Where no society-based or manufacturer guidance on radiation limits to neuromodulation devices is available, this research provides the groundwork for neurosurgeons and radiation oncologists who rely on the computerized treatment plan clinically for cancer patients.
Since the first commercial multichannel cochlear implant was marketed by Cochlear in 1985 (1), use of the device has grown exponentially. As of mid-2010, more than 188,000 people worldwide have received a cochlear implant system (2). Recent developments in the manufacturing of cochlear implants by the market leader, Cochlear Limited (based in Australia), have resulted in an aim to provide electronically stable models (3).
Abstract -- In order to determine a mouse's dose accurately and prior to engaging in live mouse radiobiological research, a tissue-equivalent tumor-bearing phantom mouse was constructed and bored to accommodate detectors. Comparisons were made among four different types of radiation detectors, each inserted into the mouse phantom for radiation measurement under a 6 MV linear accelerator beam.
Skyshine radiation emanating from medical accelerator facilities is a phenomenon not well understood.
As promulgated by the Nuclear Regulatory Commission, packaging regulations for radioactive material are confusing (e.g., “activity” vs “contained” activity vs “total” activity). As a consequence, medical physicists are forced to secondguess the intent of the regulations.
Recent improvements to the functionality and stability of implantable pacemakers and cardioverter-defibrillators involve changes that include efficient battery power consumption and radiation hardened electrical circuits. Manufacturers have also pursued MRI-compatibility for these devices
Vascular access ports are used widely in the administering of drugs for radiation oncology patients. Their dosimetric effect on radiation therapy delivery in photon beams has not been rigorously established. In this work, the effects on external beam fields when any of a variety of vascular access ports were included in the path of a high energy beam are studied. This study specifically identifies sidescatter and backscatter consequences as well as attenuation effects.
