The Cauldron, 2015, Issue 02

Fall 2015, Issue 2 of The Cauldron. In The Cauldron\u27s first-ever online-only issue, we examine the everchanging idea of the gender binary through talking with those who believe in it and those who do not. We also preview TEDxCSU and showcase women\u27s soccer and the Rec Center\u27s new Pink Gloves Boxing class. We catch up with a CSU professor who wrote a local theatre piece and we examine why Issue 3 is a bad deal for pot smokers in Ohio.https://engagedscholarship.csuohio.edu/cauldron_archives/1001/thumbnail.jp

The Cauldron, 2015, Issue 07

In issue 7 of The Cauldron we welcomed new Police Chief Gary Lewis and celebrated National Coming Out Day. We looked at the life of a CSU athlete and did a review of the Cavs scrimmage. Then, we discussed what it is like to work an on campus job and we also reviewed the TV show American Horror Story: Hotel. Finally, we discussed the importance of student journalists and why it is important to utilize your professors\u27 office hours.https://engagedscholarship.csuohio.edu/cauldron_archives/1006/thumbnail.jp

Anatomy-Based Transmission Factors for Technique Optimization in Portable Chest X-ray

Currently, portable x-ray examinations do not employ automatic exposure control (AEC). To aid in the design of a size-specific technique chart, acrylic slabs of various thicknesses are often used to estimate x-ray transmission factors for patients of various body thicknesses. This approach, while simple, does not account for patient anatomy, tissue heterogeneity, and the attenuation properties of the human body. To better account for these factors, in this work, we determined x-ray transmission factors using computational patient models that are anatomically realistic. A Monte Carlo program was developed to model a portable x-ray system. Detailed modeling was done of the x-ray spectrum, detector positioning, collimation, and source-to-detector distance. Simulations were performed using 18 computational patient models from the extended cardiac-torso (XCAT) family (9 males, 9 females; age range: 2-58 years; weight range: 12-117 kg). The ratio of air kerma at the detector with and without a patient model was calculated as the transmission factor. The transmission factor decreased exponentially with increasing patient thickness. For the range of patient thicknesses examined (12-28 cm), the transmission factor ranged from approximately 25% to 2.8% when the air kerma used in the calculation represented an average over the entire imaging field of view. The transmission factor ranged from approximately 25% to 5.2% when the air kerma used in the calculation represented the average signals from two discrete AEC cells. These exponential relationships can be used to optimize imaging techniques for patients of various body thicknesses to aid in the design of clinical technique charts.https://engagedscholarship.csuohio.edu/u_poster_2014/1022/thumbnail.jp
