    Comparison of measurements of the uterus and cervix obtained

    PURPOSE To compare measurements of the uterus and cervix obtained with magnetic resonance imaging (MRI) and transabdominal ultrasound to determine whether ultrasound can identify the brachytherapy target and be used to guide conformal brachytherapy planning and treatment for cervix cancer. METHODS AND MATERIALS Consecutive patients undergoing curative treatment with radiation therapy between

  • fabrication of conformal ultrasound transducer arrays

    Fabrication of Conformal Ultrasound Transducer Arrays

    The tool path planning methods for any given cylindrical and spherical surfaces have been discussed. Based on the developed prototype system, various test cases have been performed. The experimental results have illustrated the capability of the process and its potential use in the fabrication of conformal ultrasound transducer arrays and horns.

    Ultrasound - National Institute of Biomedical Imaging

    Diagnostic ultrasound is a non-invasive diagnostic technique used to image inside the body. Ultrasound probes, called transducers, produce sound waves that have frequencies above the threshold of human hearing (above 20KHz), but most transducers in current use operate at much higher frequencies (in the megahertz (MHz) range).

    Conformal Radiotherapy - Science topic - ResearchGate

    Conformal Radiotherapy - Science topic. the very best treatment would be to use High Intensity Focused Ultrasound (HIFU) to destroy the hypoxic region of the tumor and complete the treatment

  • evaluation of the risk of stroke with confidence predictions

    EVALUATION OF THE RISK OF STROKE WITH CONFIDENCE PREDICTIONS

    Conformal Predictors (CPs) are Machine Learning algorithms that can provide reliable confidence measures to their predictions. In this work, we make use of the Conformal Prediction framework for the assessment of stroke risk based on ultrasound images of atherosclerotic carotid plaques.

  • three-dimensional conformal brachytherapy for prostate cancer

    Three-dimensional conformal brachytherapy for prostate cancer

    Because innovations in radiation treatment planning have dramatically improved the precision of external beam radiotherapy for prostate cancer with the advent of conformal three-dimensional conformal therapy and intensity modulated radiotherapy, similar developments are emerging for prostate brachytherapy. Computer software programs are facilitating the ability to rapidly create conformal

    Automated Conformal Ultrasound Scanning for Breast Screening

    Previously we have developed a conformal ultrasound scanning system for linear scanning only. The system setup is shown in Fig. 1, and details about the operation of the developed system are

  • ultrasonic cleaning

    Ultrasonic Cleaning

    9.2.1.4 Ultrasound. Ultrasonic cleaning is a common technique of modern dentistry. It is used for both periodontal and peri-implant treatments. The ultrasonic tip is made of very thin hardened steel. Vibration induces a phenomenon called cavitation, which is the formation of cavities or bubbles in a liquid medium containing gas or vapor.

    Recommendations for MRI-based contouring of gross tumor

    A more conformal and targeted radiation dose to the macroscopic tumor in nonmetastatic pancreatic cancer is likely to reduce acute toxicity and improve local control. Optimal soft tissue contrast is required to facilitate delineation of a target and creation of a planning target volume with margin reduction and motion management.
