  1. 1. Volume calculation of the thyroid gland from SPECT images based on Monte Carlo simulations

    Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Radiofysik; Umeå universitet/Institutionen för fysik

    Författare :Niklas Palmqvist; [2018]
    Nyckelord :nuclear medicine xeleris thyroid hyperthyroidism thyrotoxicosis monte carlo technetium iodine;

    Sammanfattning : In this study the volume determination which is a part of the doseplanning for patients with thyrotoxicosis was investigated. The aim was to find an accurate method to determine the active volume with single photon emission tomography (SPECT) which in several studies have shown better results than with the currently used method planar scintigraphy (PS).

  3. 2. Simulations and Measurements of radiation doses from patients treated with I-131.

    Master-uppsats, Umeå universitet/Radiofysik

    Författare :Daniel Gälman; [2018]
    Nyckelord :I-131; Iodine-131; Monte-Carlo Simulations; dose rate measurements; taxi driver; newborn; thyrotoxicosis; restriction times; thyroid cancer;

    Sammanfattning : The aim of this work is to introduce a couple of new exposure scenariosof interest when personnel, family members and general public are externally irradiated from patients treated with Iodine-131. A series of modied ORNL matematical phantoms were used in Monte-Carlo simulations in PENELOPE-2011 to determine dose rates to: a cab driver where thepatient sits in the back seat at opposite side, a newborn child held by an adult patient, a doctor giving treatment to a patient while leaning over the hospital bed and collective effective dose to bus passengers if the patient travels home by bus.

  4. 3. Empirical measurements to ensure compliance with post therapy dose constraints to family members of radioiodine therapy patients

    Uppsats för yrkesexamina på grundnivå, Medicinsk strålningsfysik (tills m KI)

    Författare :Itembu Lannes; [2007]
    Nyckelord :Radioiodine therapy; TLD; dose constraint;

    Sammanfattning : Radioiodine has been used in nuclear medicine for the treatment of thyroid diseases such as Thyroid Cancer and Thyrotoxicosis for many years. The treatment renders the patient radioactive. To minimize the dose to the patients’ relatives and the general public, restric-tions are imposed on the behaviour of the patient. LÄS MER
