Title: Detection of foreign body using fast thermoacoustic tomography with a multielement linear transducer array

Abstract

Current imaging modalities face challenges in clinical applications due to limitations in resolution or contrast. Microwave-induced thermoacoustic imaging may provide a complementary modality for medical imaging, particularly for detecting foreign objects due to their different absorption of electromagnetic radiation at specific frequencies. A thermoacoustic tomography system with a multielement linear transducer array was developed and used to detect foreign objects in tissue. Radiography and thermoacoustic images of objects with different electromagnetic properties, including glass, sand, and iron, were compared. The authors' results demonstrate that thermoacoustic imaging has the potential to become a fast method for surgical localization of occult foreign objects.

  • Multielement microelectrode arrays have been developed for electrochemical sensors. The array sensors are fabricated on a single insulated silicon substrate (standard 2 in. wafer) using photolithographic methods. In the prototype devices, five different electrode materials have been included: Pt, Au, V, Ir, and carbon. One goal of this work was to quantitate the improvement in information content for voltammetric measurements with a matrix of different electrode materials relative to measurements made with a single electrode material. Additionally, the authors have developed fabrication methods for multielement microelectrode array detectors and evaluated their voltammetric characteristics. Ultimately, they are working toward the developmentmore » of inexpensive and reproducible methods of producing these arrays so that they could be used in a disposable fashion. In order to accomplish the present goals, voltammetric data were obtained for a group of four explosive and four nonexplosive (but structurally similar) compounds in dimethyl sulfoxide using the microsensor array. The information content of these measurements was then evaluated by using the probabilistic model developed by Shannon. It was found that the information content was improved by using the multielement approach, with the average information content increasing by 25% relative to the case where a single platinum microelectrode array was used. Although their use thus far has been limited to laboratory applications, these disposable arrays could also be used in natural environments.« less
  • Purpose: Effective permanent prostate brachytherapy (PPB) requires precise placement of radioactive seeds in and around the prostate. The impetus for this research is to examine a new ultrasound-based imaging modality, vibro-acoustography (VA), which may serve to provide a high rate of PPB seed detection while also effecting enhanced prostate imaging. The authors investigate the ability of VA, implemented on a clinical ultrasound (US) scanner and equipped with a quasi-2D (Q2D) array US transducer, to detect and localize PPB seeds in excised prostate specimens. Methods: Nonradioactive brachytherapy seeds were implanted into four excised cadaver prostates. A clinical US scanner equipped withmore » a Q2D array US transducer was customized to acquire both US and C-scan VA images at various depths. The VA images were then used to detect and localize the implanted seeds in prostate tissue. To validate the VA results, computed tomography (CT) images of the same tissue samples were obtained to serve as the reference by which to evaluate the performance of VA in PPB seed detection. Results: The results indicate that VA is capable of accurately identifying the presence and distribution of PPB seeds with a high imaging contrast. Moreover, a large ratio of the PPB seeds implanted into prostate tissue samples could be detected through acquired VA images. Using CT-based seed identification as the standard, VA was capable of detecting 74%–92% of the implanted seeds. Additionally, the angular independency of VA in detecting PPB seeds was demonstrated through a well-controlled phantom experiment. Conclusions: Q2DVA detected a substantial portion of the seeds by using a 2D array US transducer in excised prostate tissue specimens. While VA has inherent advantages associated with conventional US imaging, it has the additional advantage of permitting detection of PPB seeds independent of their orientation. These results suggest the potential of VA as a method for PPB imaging that ultimately may allow US-based real-time intraoperative dosimetry.« less
  • Recent investigations reveal an important new class of transient radio phenomena that occur on submillisecond timescales. Often, transient surveys' data volumes are too large to archive exhaustively. Instead, an online automatic system must excise impulsive interference and detect candidate events in real time. This work presents a case study using data from multiple geographically distributed stations to perform simultaneous interference excision and transient detection. We present several algorithms that incorporate dedispersed data from multiple sites, and report experiments with a commensal real-time transient detection system on the Very Long Baseline Array. We test the system using observations of pulsar B0329+54.more » The multiple-station algorithms enhanced sensitivity for detection of individual pulses. These strategies could improve detection performance for a future generation of geographically distributed arrays such as the Australian Square Kilometre Array Pathfinder and the Square Kilometre Array.« less
  • Ultrasonic guided waves have been widely employed for the long range inspection of structures such as plates, rods and pipes. In ultrasonic guided waves, however, there are numerous modes with different wave velocities, so that the generation and detection of the appropriate wave mode of the guided wave is one of key techniques in the application of guided waves. In the present work, mode tuning using an array transducer was investigated with the hardware implements to generate ultrasonic guided waves in a seamless stainless steel pipe. For this purpose, 8-channel ultrasonic pulser/receiver and their controller which enables sequential activation ofmore » each channels with given time delay were developed. A series of experiments was carried out in order to demonstrate the feasibility of dynamic tuning of modes by hardware: tuning the mode of the generated guided wave, group velocity measurement, tuned receiving and mode identification. As a result, the selective tuning of wave mode can be achieved by changing the time interval between adjacent elements of an array transducer.« less
