  2. 21. Continuous-Time Delta-Sigma Modulators for Wireless Communication

    Author : Mattias Andersson; Institutionen för elektro- och informationsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; return-to-zero; A D converter; loop delay; delta-sigma; ADC; CMOS; STF; continuous-time; sigma; delta; filtering; CT; RZ;

    Abstract : The ever increasing data rates in wireless communication require analog to digital converters (ADCs) with greater requirements on speed and accuracy, while being power efficient to prolong battery life. This dissertation contains an introduction to the field and five papers that focus on the continuous-time (CT) Delta-Sigma modulator (DSM) as ADC. READ MORE

  4. 22. Theranostics in Neuroendocrine Tumors : Somatostatin Receptor Imaging and Therapy

    Author : Ezgi Ilan; Mark Lubberink; Peter Bernhardt; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; 177Lu-DOTATATE; 68Ga-DOTATATE; 68Ga-DOTATOC; PRRT; Theranostics; PET CT; SPECT CT; Neuroendocrine tumors; Somatostatin receptors; Medicinsk radiofysik; Medical Radiophysics;

    Abstract : Neuroendocrine tumors (NETs) are characterized by cellular overexpression of somatostatin receptors (SSTR), which allows for the use of radiolabeled somatostatin analogs (SSA) for both imaging and therapy. Because NETs often are diagnosed at a metastatic stage, curative surgery is not possible. READ MORE

  5. 23. Detecting prostate cancer metastases - PET/CT and the sentinel node technique

    Author : Henrik Kjölhede; Malmö Urologisk cancerforskning; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Prostate cancer; Metastases; PET CT; Choline; Fluoride; Sentinel lymph nodes;

    Abstract : Prostate cancer is one of the most common malignancies. Its treatment is highly dependent on the presence or absence of metastases. The available invasive and non-invasive modalities for detecting metastases are imperfect. READ MORE

  6. 24. Artificial Intelligence-based Assessment of Prostate Cancer Metastases in PET/CT

    Author : Sarah Lindgren Belal; Malmö Nuklearmedicin; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Artificial intelligence AI ; Convolutional neural networks CNN ; PET CT; Prostate cancer; Automated; Tumor burden; Bone metastases; Lymph node metastases;

    Abstract : Background: Quantification of tumor burden from bone scan in the form of automated Bone Scan Index (aBSI) has been validated as an imaging biomarker for patients with prostate cancer. Positron emission tomography combined with computed tomography (PET/CT) is more sensitive and accurate compared to conventional imaging such as bone scan. READ MORE
