  3. 12. An Investigation on PVDF Piezoelectric Elements and Linear Array Transducers

    University essay from Lunds universitet/Teknisk akustik; Lunds universitet/Institutionen för byggvetenskaper

    Author : Ali Alkhudri; [2017]
    Keywords : Ultrasonic Transducer; Piezoelectric Element; PVDF; Frequency; Ultrasound Wave Penetration; PZT; Acoustic Impedance; raw data; linear array transducer; Technology and Engineering;

    Abstract : Ultrasonic waves are widely used in different application e.g. for sonar scanning in water and fetal imaging. Furthermore it is used for doing measurements on different materials to determine the thickness of the material or the velocity of sound inside it. READ MORE

  4. 13. Implementation of Shear Wave Elastography in Cervical Applications

    University essay from KTH/Skolan för teknik och hälsa (STH)

    Author : Anna Larsson; [2016]
    Keywords : Shear wave elastography; cervix; stiffness; Verasonics; curvilinear transducer;

    Abstract : Each year million of babies are born pre-term, some of these pre-term births occur due to the motherhaving a too soft cervix which can not withstand the forces the baby exposes it to. The aim of thisstudy was to implement and evaluate a programmable shear wave elastography ultrasound system forcervical applications and investigate the optimal settings of shear wave elastography push voltage andshear wave elastography push focus depth.

  5. 14. Determination of thyroid volume by ultrasound

    University essay from

    Author : Thu Nguyen Thi; [2016]
    Keywords : thyroid volume; ultrasound; transducer; radiographer;

    Abstract : Background: Ultrasound is safe and painless, produces pictures of the inside of the body using sound waves (not use ionizing radiation), thus there is no radiation exposure to the patient. The thyroid gland is among the most commonly imaged glands using ultrasound due to the limitation of clinical examination. READ MORE

  6. 15. Assessment of Shear Wave Elastography Acoustic Output - a Simulation and Experimental Study

    University essay from KTH/Skolan för teknik och hälsa (STH)

    Author : Cristiana Golfetto; [2016]
    Keywords : Technology;

    Abstract : Shear Wave Elastography (SWE) is a medical imaging modality which is able to measure tissue stiffness through the speed of ultrasound-induced shear waves. Pre- vious studies have reviewed the safety aspects of clinical ultrasound, highlighting the harmlessness of the technique. READ MORE
