The academic educator's portfolio is a collection of materials that document academic performance and achievements, supplementing the curriculum vitae, in order to showcase a faculty member's most significant accomplishments. A decade ago, a survey of medical schools revealed frustration in the nonuniform methods of measuring faculty's medical education productivity. A proposed solution was the use of an academic educator's portfolio. In the academic medical community, compiling an academic portfolio is always a challenge because teaching has never been confined to the traditional classroom setting and often involves active participation of the medical student, resident, or fellow in the ongoing care of the patient...

Publications which present images containing multi-dimensional image content have traditionally been confined to present information in a static 2-dimensional format. Inclusion of videos within a publication provides enhanced opportunities to present multi-dimensional image views rather than relying on static images to communicate findings. However, asignificant advance is presented in which an image viewer in integrated into Tomography's digital publication format allowing foruser manipulated and interactive multi-dimensional viewing of published image data directly inline with the manuscript...

Noninvasive physiologic vascular studies play an important role in the diagnosis and characterization in peripheral arterial disease (PAD) of the lower extremity. These studies evaluate the physiologic parameters of blood flow through segmental arterial pressures, Doppler waveforms, and pulse volume recordings. Collectively, they comprise a powerful toolset for defining the functionality of the arterial system, localizing the site of disease, and providing prognostic data. This technology has been widely adopted by diverse medical specialty practitioners, including radiologists, surgeons, cardiologists, and primary care providers...

As the health care environment continually changes, radiologists look to the ACR's Imaging 3.0(®) initiative to guide the search for value. By leveraging new technology, a cloud-based image exchange network could provide secure universal access to prior images, which were previously siloed, to facilitate accurate interpretation, improved outcomes, and reduced costs. The breast imaging department represents a viable starting point given the robust data supporting the benefit of access to prior imaging studies, existing infrastructure for image sharing, and the current workflow reliance on prior images...

Electrical impedance tomography (EIT) is a noninvasive, non-radiologic imaging modality that may be useful for the quantification of lung disorders and titration of mechanical ventilation. The principle of operation is based on changes in electrical conductivity that occur as a function of changes in lung volume during ventilation. EIT offers potentially important benefits over standard imaging modalities because the system is portable and non-radiologic and can be applied to patients for long periods of time...

Ultra-high intensity lasers in use are connected with ionizing radiation sources that raise a real concern in relation to installations, personnel, population and environment protection. The shielding of target areas in these facilities has to be evaluated from the conceptual stage of the building design. The sizing of the protective concrete walls was determined using computer codes such as Fluka. For the experiments to be carried out in the facility of the Center for Advanced Laser Technologies (CETAL), both proton beams with the energy of 100 MeV and electron beams with 300 MeV energy were considered to calculate the dimensions of structural shielding and to establish technical solutions fulfilling the radiation protection constraints imposed by the National Commission for Nuclear Activities Control...
