    Author : Saga Söderholm; [2022-05-18]
    Keywords : Medical physics; DXA; DEXA; Dual-energy X-ray absorptiometry; Bone mineral density;

    Abstract : Purpose: The aims of this work were to evaluate the radiation environment in the dual-energy X-ray absorptiometry (DXA) rooms at Sahlgrenska University Hospital, estimate personnel doses, determine legal requirements for DXA personnel, examine the operators’ view on radiation safety and develop material with dose information for patients and operators. Theory: DXA is a low dose X-ray modality mainly used in osteoporosis examinations, for which it is considered the reference technique. READ MORE

  5. 30. 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
