Towards a bilingual graphic imaging system.
… explored the development of a 'bilingual graphic imaging system'. The 'system' is 'sociocultural', where the two languages of communication are English and the lesser used language - Gaelic. The aim of the research was to investigate the parameters and potentials of bilingual graphic design with …

Marine snow tracking stereo imaging system
… complexity of this Pump, however, together with systematic biases in available measurement methodologies and vast spatial and temporal undersampling, makes this quantification difficult. In this thesis I set out to design and build a low-cost underwater stereo-imaging system to remotely measure …

A code-division, multiple beam sonar imaging system
In this thesis, a new active sonar imaging concept is explored using the principle of code-division and the simultaneous transmission of multiple coded signals. The signals are sixteen symbol, four-bit, non-linear, block Frequency-Shift Keyed (FSK) codes, each of which is projected into a different …

SMARTPHONE-BASED COMPRESSION-INDUCED IMAGING SYSTEM DATA SECURITY
The Smartphone-based Compression-Induced System (SCIS) is developed to obtain the mechanical properties of a tumor. Using a SCIS smartphone app, we obtain tactile images, and we developed data security methodology in this thesis. The first version of the system (SCIS V1) is developed using the …

Objective Assessment Methods for List Mode Imaging System
… properly quantify the imagequality of a medical imaging system, both the task and observer have to be well defined. The objective quality of the image depends on how well the specified observer can extract the desired information to perform the task. Classification or detection tasks are often …

Statistical modeling of radiation detection and imaging system
In the development of SPECT system for imaging small animal in vivo, higher spatial resolution is continuously sought to provide improved spatial detail and image quality. However, the pursuit of high resolution often results in the poor photon collection efficiency and limited quantitative …

Development of a motion-free tomographic imaging system
… the size, weight, and expense of CT systems make them inaccessible for patients outside of large trauma centers. We have designed a module containing multiple miniature x-ray source that would allow for CT scanners to be significantly lighter weight and cheaper, and to operate without …

Second Generation Tactile Imaging System for Mechanical Properties Estimation
The Tactile Imaging System (TIS), developed in the Control, Sensor, Network, and Perception (CSNAP) Laboratory at Temple University, is a novel non-invasive method to measure the size and elastic modulus of inclusions. In this thesis, we revamped TIS to enlarge the contact area and replaced the …

Design of a Microwave Imaging System for Target Identification
… the construction and evaluation of a microwave imaging system to reconstruct images of unknown targets. In our system, we primarily use the common Wi-Fi frequencies of 2.4 GHz and 5 GHz because of the wide availability of commercial microwave components that operate at these frequencies. For the …

Multiplexer Design for a Multi-Array Ultrasonic Imaging System
… of a novel conformable multi-array ultrasound imaging system. Synthetic array ultrasound data is acquired and processed using delay-and-sum beamforming to form individual array images, then the images are combined to provide an expanded field of view compared to a single-array system.
