Positron Emission Tomography (PET) is an imaging modality that has become increasingly beneficial in Radiotherapy by improving treatment planning (1). PET reveals tumor volumes that are not well visualized on computed tomography CT or MRI, recognizes metastatic disease, and assesses radiotherapy treatment (1). It also reveals areas of the tumor that are more radiosensitive allowing for dose painting - a non-homogenous dose treatment across the tumor (1). However, PET is not without limitations. The quantitative unit of PET images, the Standardized Uptake Value (SUV), is affected by many factors such as reconstruction algorithm, patient weight, and tracer uptake time (2). In ...


Improving Pediatric Cardiology Consultation Methods By Introducing Digital Interactive 3-D Heart Models: A Proof Of Concept Study, Adam Verigan Jul 2007

Improving Pediatric Cardiology Consultation Methods By Introducing Digital Interactive 3-D Heart Models: A Proof Of Concept Study, Adam Verigan

Graduate Theses and Dissertations

The purpose of a pediatric cardiology consultation is to inform, or educate, the patient and family of all aspects surrounding a certain congenital heart defect. Consultation education methods and materials may include verbal descriptions, two-dimensional (2-D) heart diagrams, and take-home pamphlets. Because the human heart is a complex three-dimensional (3-D) object, the problem lies within the clarity to which these methods are performed by the doctors and understood by the patients and families. Therefore, during a consultation the cardiologist must a) possess the ability to describe a defect visually as well as verbally and b) ensure that the patient and ...
