Cartesian positioning system for localization of blast and ballistic fragments: a phantom-based pilot study.

Our purpose was to demonstrate the consistency of radiologists' three-dimensional measurements of simulated blast fragment locations in vitro in an effort to objectively localize retained fragments and wound paths. We designed a phantom consisting of 10 nail heads (simulating blast fragments) glued to wooden pegs that were randomly situated at distances from a reference point within a plastic tub. The x, y, and z coordinates of simulated fragments were recorded in Cartesian 3-space relative to the reference point.

Situs inversus totalis.

We present a case of situs inversus totalis. A 22-month-old infant presented with cyanosis, double-inlet left ventricle, severe pulmonary stenosis, and concern for underlying visceroatrial abnormalities. Chest (Fig.

CT-based ballistic wound path identification and trajectory analysis in anatomic ballistic phantoms.

Purpose: To evaluate the accuracy of computed tomography (CT)-based ballistic wound path identification in phantoms by determining the agreement between actual shooting angles and both trajectory angles measured with a picture archiving and communication system (PACS) angle tool and angles calculated from x, y, z coordinates of the entrance and exit points.

Materials And Methods: In this institutional review board-approved model study, two simulated legs were shot by a trained marksman from 50 yards at six clinometer-measured angles with a 0.30-06 rifle and then scanned at multidetector CT.
