  1. 1. Validation of the Effectiveness of a Sensory Discrimination Training Device

    Master-uppsats, KTH/Medicinteknik och hälsosystem

    Författare :Malin Lehander; [2022]
    Nyckelord :Sensory training; Phantom limb pain; Mindful sensory motor training; Amputation; Pain treatment;

    Sammanfattning : Successful treatment alternatives for chronic pain conditions are limited. One type of chronic pain that can occur is the condition of phantom limb pain, which can occur after the loss of a limb. Many studies have researched the correlation between chronic pain, tactile acuity, and cortical reorganization. LÄS MER

  3. 2. Evaluation of the impact of reduced scan field-of-view (SFOV) on CT radiation dose and image quality in a chest CT – a phantom study

    Magister-uppsats, Örebro universitet/Institutionen för hälsovetenskaper

    Författare :Fleury Ndongozi; [2022]
    Nyckelord :;

    Sammanfattning : Background: Technical development of image detectors and dose-reduction techniques in computed tomography (CT) have contributed to reduce radiation dose for patient and staff. The scan field of view (SFOV) generally affects the radiation dose the patient will beexposed. LÄS MER

  4. 3. Enhancing Sensory Discrimination Training using Brain Modulation

    Master-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Författare :Agnes Westerlund; [2022]
    Nyckelord :Transcranial direct current stimulation; sensory discrimination training; tactile acuity; phantom limb pain; two-point discrimination test; Semmes-Weinstein monofilament test;

    Sammanfattning : Damage to the nervous system may cause sensorimotor impairment, often resulting in chronic neuropathic pain. Phantom limb pain affects multiple amputees and the treatment options are limited. A promising treatment option to reduce chronic pain is by training sensory discrimination. LÄS MER

  5. 4. EVALUATION OF RADIATION DOSES USING CONE BEAM COMPUTED TOMOGRAPHY IN ENDOVASCULAR AORTIC REPAIR AND SCOLIOSIS PROCEDURES

    Master-uppsats,

    Författare :Louise Strandberg; [2021-04-06]
    Nyckelord :Medical physics; Cone beam CT; CT; EVAR; scoliosis; radiation dose; effective dose;

    Sammanfattning : Purpose: The study includes the two areas, vascular surgery and orthopedics, and focuses on endovascular aortic aneurysm repair (EVAR) and scoliosis procedures. EVAR procedures contribute to a high radiation dose to the patient and for scoliosis procedures, it is often young girls that are undergoing surgery. LÄS MER

  7. 5. Investigation of a Collapsed Cone Superposition Algorithm for dosimetry in brachytherapy

    Master-uppsats, Stockholms universitet/Fysikum

    Författare :Freja Alpsten; [2021]
    Nyckelord :Brachytherapy; Collapsed Cone; Model-Based Dose Calculation Algorithms; Radiotherapy;

    Sammanfattning : Background & Purpose: The current standard dosimetry in brachytherapy treatment planning, the TG-43 formalism, ignore the presence of non-water media and finite patient dimensions. This can cause clinically relevant errors in dose estimates. LÄS MER
