  1. 1. Development of patient-specific fetal head phantom for experimental evaluation of vacuum assisted delivery

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Maria Pop; [2021]
    Keywords : Vacuum assisted delivery; Vacuum extractor device; Traction force; Vacuum pressure; Fetal head phantom; Ultrasound imaging; Sonomicrometry;

    Abstract : Vacuum assisted delivery (VAD) is a common procedure used in the final stage of labor in the situation of a difficult natural delivery. Since the only biomechanical studies concerning the clinical safe traction force were conducted during 70s using simplified models to mimic the fetal head, concerns remain regarding the side effects of this medical intervention when applying high levels of traction forces.

  3. 2. Microwave phantoms for Craniotomy and bone defect monitoring

    University essay from Uppsala universitet/Fasta tillståndets elektronik

    Author : Velander Jacob; [2015]
    Keywords : agar; BMP; body morphogenetic protein; bone implant; brain phantom; craniosynostosis; craniotomy; cube phantom; phantom; re-growing bone; skin phantom; skull phantom; tissue;

    Abstract : To facilitate examination for osteogenesis and follow up after craniotomy similar head models called phantoms are made. The head phantom should emulate the tissues from a real head. This requires that the realistic head phantom have the same electrical properties as relative permittivity (dielectric constant) and conductivity. READ MORE

  4. 3. Dosimetry for the Lens of the Eye, Applications for Medical Staff Involved in Interventional Radiology Procedures

    University essay from Lunds universitet/Sjukhusfysikerutbildningen

    Author : Therese Geber; [2010]
    Keywords : Röntgen; Medicine and Health Sciences;

    Abstract : "Background: Cataract (opacity of the lens of the eye) has always been thought of as a deterministic effect. That is, that there is a threshold dose below which damage does not occur. However, recent studies suggest a lower threshold and the question whether there is any threshold at all has been raised. READ MORE
