A woman whose radiographs showed subcutaneous metallic objects

Well woman care: whose responsibility?

GENERAL practice primary care teams are taking more lJresponsibility for preventive medicine and there is evidence that patients welcome health promotion activities on the part of their general practitioner. ' Already, in some districts, as little as 5% of pre-school child health services are provided by clinical medical officers2 and, although opinions about this vary, there is general agreeme...

3d Reconstruction of Localized Objects from Radiographs

We study the reconstruction of a 3D image from a limited set of radiographs. In nondestructive testing of materials, such 3D images represent the map of attenuation of the inspected material. The reconstruction task is very useful to detect the presence of localized objects inside the material (e.g., air anomalies inside a metal), and to localize their position. We introduce parametric image mo...

Metallic foreign body in esophagus: are multiple radiographs necessary?

BACKGROUND Multiple X-rays required for confirmation and localization of ingested metallic foreign body preoperatively predisposes children to increased radiation exposure. This study aims to highlight the current necessity or otherwise of these X-ray requests. MATERIALS AND METHODS This is a retrospective study of patients with ingested metallic foreign bodies over a five-year period in a te...

Temperature of Metallic Objects in Space.

Casimir repulsion between metallic objects in vacuum.

We give an example of a geometry in which two metallic objects in vacuum experience a repulsive Casimir force. The geometry consists of an elongated metal particle centered above a metal plate with a hole. We prove that this geometry has a repulsive regime using a symmetry argument and confirm it with numerical calculations for both perfect and realistic metals. The system does not support stab...
