Development and use of military-unique standardized gynecology patients for military residents in obstetrics and gynecology training programs.

Focused military curricula and readiness training are often inadequate for military resident physicians. We developed a standardized gynecologic military-unique patient scenario and examination to assess obstetrics and gynecology residents' clinical and operational problem-solving abilities. Integration of military-unique gynecologic standardized patients, clinical scenarios, and objective structured clinical examinations into obstetrics and gynecology curricula is a novel approach for realistic medical readiness training for resident physicians. This tool can become a cornerstone in the ongoing development of needed military-unique curricula.

A novel comprehensive quality control instrument for medical accelerators.

A comprehensive quality control instrument for calibration of medical accelerators that use photon, electron, or proton beams in teleradiotherapy is described. It employs a fluorescence screen, mounted on a central stage with four degrees of freedom, monitored by a CCD camera. A single set-up of the instrument enables one to perform mechanical, light laser, and radiation tests, at arbitrary angles of the accelerator gantry. The new device provides for quantitative evaluation of the tests performed and provides for documentation of the test results in real time. The device provides significant time savings with concurrent improvement in accuracy for tests performed during installation and acceptance processes, and the implementation of quality control procedures for medical accelerators.

Depth dose and profile analysis using Library Least-Squares method.

The Library Least-Squares method has been applied to detect changes in the depth dose and in the profiles of 6 and 20 MeV electron beams, and in 6 MeV photon beams from medical linear accelerators. The changes in the beam energy of 0.78% and 0.32% at low and high electron energies, respectively, induced by the insertion of 0.1 mm A1 absorber were clearly visible in the residual distributions. The changes in the photon beam were introduced by rotation of the gantry or the collimator. The applicability of the method to quantitatively monitor any changes in the treatment beam characteristics is presented.
