Toward Electric Field Tomography
This thesis addresses the problem of recovering three-dimensional location and shape information from measurements made with Electric Field Sensors. A single sensor functions as a proximity detector; two can be used as a mouse; three allow tracking of the hand in three dimensions, and each additional sensor allows us to extract additional shape information. The ultimate goal of this work is to ...

متن کاملA DSP Based Stress Wave Instrument for Wood Decay Detection
To improve the performance of wood decay detection, a DSP based instrument is developed using stress wave technology. Two piezoelectric receivers are used to sense the start and stop signal. The received signals are then processed with DSP technique in order to obtain the stress wave transmission time with high accuracy. In addition to the hardware design, we discuss the propagation time estima...
متن کاملComparison of transportation and centering ability using RECIPROC and iRace: A cone-beam computed tomography study
BACKGROUND AND AIM: Root canal treatment, especially in curved and constricted root canals, can be very difficult and time consuming. Several investigations have compared the reciprocating and full sequence motions in terms of shaping ability. The purpose of the present study was to compare the root canal transportation and centering ability of RECIPROC and iRace using cone-beam computed tomogr...
متن کاملComparison of cone beam computed tomography and digital radiography in detection of pulpal exposure in external cervical root resorption
Background and Aims: Pulpal exposures originated from the external cervical root resorptions have major effects on the treatment and prognosis. Therefore, the aim of this study was performed to compare the two different imaging systems-digital radiography with PSP (Photostimulable Phosphor) sensor in three horizontal different views and CBCT (cone beam computed tomography) images to assess the ...
