  1. 1. Evaluation of whole-body bone scans performed using a gamma camera with Cadmium Zinc Telluride detector

    University essay from

    Author : Victor Asp; [2022-01-13]
    Keywords : Medical physics; whole-body bone scans; gamma camera; Cadmium Zinc Telluride detector;

    Abstract : The bone scan is a common nuclear medicine imaging procedure that is mainly used for evaluating several oncological patient groups. A radioactive tracer, 99mTc -labelled diphosphonate, is injected intravenously and accumulates in the skeleton. The distribution of the tracer in the body is measured with a gamma camera 3 hours post-injection. READ MORE

  2. 2. STANDARDIZED ORGAN AT RISK VOLUME FOR EXTERNAL BEAM RADIATION THERAPY IN PROSTATE CANCER AND ITS RELATIONSHIP TO VOLUMES DEFINED BY CLINICAL PRACTICE

    University essay from

    Author : Dang Thao; [2022-01-13]
    Keywords : Medical physics; Radiation therapy; Prostate cancer; Organs at risk;

    Abstract : Background/ Purpose: In radiation therapy (RT), the radiation dose calculated in tumours and normal tissue depends on how the volumes are defined. It is difficult to standardize how tumour volumes should be defined because their anatomical extension can differ greatly between individuals. READ MORE

  3. 3. Establishment of a deep learning algorithm for dosimetry of radiopharmaceuticals

    University essay from

    Author : Dennis Lipnicevic; [2022-01-13]
    Keywords : Medical physics; automated segmentation; dosimetry; kidney; nuclear medicine dosimetry; deep learning; convolutional neural network;

    Abstract : Purpose: The aim of this study was to introduce a volumetric convolutional neural network for segmentation of the kidneys in SPECT images and to apply it in the dosimetry of radiopharmaceuticals of this organ, in order to decrease segmentation time and to standardize the segmentation of the kidneys. Method: Three networks were trained using two network architectures and a total of 216 retrospectively collected images from patients that underwent imaging procedures at Sahlgrenska University Hospital between 2009 and 2018.

  4. 4. Early Detection and Differentiation of Circulatory Shock in the Intensive Care Unit using Machine Learning

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

    Author : Therese Lindberg; [2022]
    Keywords : machine learning; prediction; circulatory shock; intensive care unit; ICU;

    Abstract : In the intensive care unit, patients with crucial, life-threatening conditions are admitted and need constant monitoring. Here, the need for a quick and efficient decision support tool is the greatest. READ MORE

  5. 5. Phenotypic profiling and drug screening in Rhabdomyosarcoma cell lines

    University essay from Uppsala universitet/Institutionen för farmaceutisk biovetenskap

    Author : Laura Martina Lang; [2022]
    Keywords : Rhabdomyosarcoma; Phenotypic profiling; Phenotypic drug screening;

    Abstract : Rhabdomyosarcoma (RMS) is a type of soft tissue sarcoma that mainly occurs in children. RMS can be divided into two subtypes embryonal (ERMS) and alveolar (ARMS). The ARMS subtype can be especially aggressive when a balanced chromosomal translocation is present. READ MORE
