Roentgen Stand for Field Positioning in High-Energy Radiotherapy

An Indoor Positioning System Based on Wi-Fi for Energy Management in Smart Buildings

To offer indoor services to occupants in the context of smart buildings, it is necessary to consider information concerning to the identity and location of the occupants. This paper proposes an indoor positioning system (IPS) based on Wi-Fi fingerprint and K-nearest neighbors (KNN) method. The positioning of a mobile device (MD) using Wi-Fi technology involves online and offline phases. In this...

Dosimetric comparison of whole breast radiotherapy using field in field and conformal radiotherapy techniques in early stage breast cancer

Background: We aimed to compare field-in-field technique (FIF) with conformal tangential field radiotherapy (CRT) in terms of dosimetric benefits for early stage breast cancer radiotherapy. Materials and Methods: Twenty consecutive left-side breast cancer patients who underwent breast-conserving surgery were included to the study. For each patient, two different treatment plans were cr...

Strategic positioning: where does your organization stand?

O ver 20 years ago, the concept of strategic positioning was popularized by Jack Trout and Al Ries in their seminal publication Positioning: The Battle for Your Mind (McGraw Hill, 1981). Although this concept has been enthusiastically embraced by many industries, its application in healthcare has been laggard at best. Because almost all healthcare organizations in the United States continue to ...

Internal high linear energy transfer (LET) targeted radiotherapy for cancer.

High linear energy transfer (LET) radiation for internal targeted therapy has been a long time coming on to the medical therapy scene. While fundamental principles were established many decades ago, the clinical implementation has been slow. Localized neutron capture therapy, and more recently systemic targeted alpha therapy, are at the clinical trial stage. What are the attributes of these the...
