  1. 1. Exposure Monitoring and Dosimetry - Optimizing Radiation Protection in Interventional Cardiology

    University essay from Umeå universitet/Institutionen för fysik; Umeå universitet/Institutionen för strålningsvetenskaper

    Author : Amanda Pettersson; [2023]
    Keywords : Interventional cardiology; Radiation protection; Air kerma measurements; Radiation shielding; Projection angle;

    Abstract : During interventional cardiology (IC), medical staff are exposed to scattered ionizing radiation from the patient, potentially leading to various radiation-induced health effects. Therefore, shielding devices are routinely used to reduce occupational exposure during IC procedures. READ MORE

  3. 2. Evaluation of the treatment planning system decimal ElectronRT and custom-made bolus for FLASH-irradiation

    University essay from Lunds universitet/Sjukhusfysikerutbildningen

    Author : Mizgin Coskun; [2022]
    Keywords : Medicine and Health Sciences;

    Abstract : Introduction: The novel external beam therapy technique using ultra-high dose rates known as FLASH has become known for its normal tissue sparing effect. Currently in Lund, veterinary clinical trials are carried out on canine patients using electrons with ultra- high dose rates. READ MORE

  4. 3. Control of 3D-printed Hand Prosthetic via Intra-body Fat Channel Communication

    University essay from Uppsala universitet/Fasta tillståndets elektronik

    Author : Eric Trollsås; [2022]
    Keywords : Fat-IBC; IBAN; Prosthetics; ATE Phantom; Phantom Tissue; 3D-printing; ZigBee;

    Abstract : Intra-Body Communication (IBC) is a prospective technology where human tissue may be used as a signal medium in order to transmit useful data within the human body. Proposed applica- tions of this technology are prosthetics control or implanted device communication, potentially by establishing an Intra-Body Area Network (IBAN), which could further be enhanced by other IoT applications and 5G radio systems.

  5. 4. Whole-body SAR measurements of 5G mmW base stations in a reverberation chamber

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Jens Eilers Bischoff; [2022]
    Keywords : Reverberation chamber; Whole body specific absorption rate; 5G; Absorption; Antenna measurements; Modväxlande kammare; Helkroppsbaserad specifik absorptionshastighet; SAR; 5G; Absorption; Antennmätningar;

    Abstract : This study presents a method for measurement of whole-body average specific absorption rate (WBSAR) of a millimeter wave (mmWave) antenna in a reverberation chamber. The method takes advantage of multiple radiated power measurements to estimate the power absorbed in a phantom placed in front of the antenna. READ MORE

  6. 5. FETAL DOSE ESTIMATION IN ABDOMINAL AND PELVIC CT EXAMINATIONS

    University essay from

    Author : Olivia Carlstein; [2021-05-10]
    Keywords : Medical physics; Fetal dose; abdominal CT examination; pelvic CT examination; phantom measurement;

    Abstract : Purpose: The purpose of this is study was to compare different methods for estimating the fetal dose, how much the different methods differ from each other and on which dose levels the fetal doses are estimated to. Theory: A radiological procedure should always be justified and in the case of a pregnant patient the justification should include both the mother and the fetus. READ MORE
