  1. 1. Spatialized Sonification for the Learning of Surgical Navigation

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Alexander Danielsson; [2023]
    Nyckelord :Spatial Audio; Sonification; Surgical Simulations; Minimally invasive Surgery; Psychoacoustics; Spatial Ljud; Sonifikation; Kirurgiska Simulationer; Minimalinvasiv kirurgi; Psykoakustik;

    Sammanfattning : Historically, the education of surgical navigation in minimally invasive neurosurgery has been constrained by several factors. Medical students have been required to physically be in the operating room to observe a teacher perform the different procedures. This restricts their opportunities to gain valuable hands-on experience in their field. LÄS MER

  3. 2. Object shape and depth perception in VR

    Kandidat-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :David Persson; Kristi Francis; [2023]
    Nyckelord :virtual reality; depth perception; minimally invasive neurosurgery;

    Sammanfattning : Virtual reality (VR) for surgical training shows promise in preparing surgeons for complex procedures. However, achieving a high level of realism in VR is essential for the skills acquired to translate effectively into real-world applications. LÄS MER

  4. 3. A Machine Learning Approach to Skin Cancer Delineation on Photoacoustic Imaging

    Master-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Beräkningsbiologi och biologisk fysik - Genomgår omorganisation

    Författare :Alice Fracchia; [2023]
    Nyckelord :Skin cancer; carcinoma; photoacoustic imaging; ultrasound imaging; machine learning; dimensionality reduction; sandpiles algorithm; active contour; multilayer perception MLP ; convolutional neural networks CNN ; autoencoder; Physics and Astronomy;

    Sammanfattning : Skin cancer is a growing public health concern due to its prevalence among the population. Current clinical procedures require high invasiveness and multiple surgeries, which are responsible for patient discomfort and high medical expenses. LÄS MER

  5. 4. Design and evaluation of a novel Transillumination SFDI system for quantitative assessment of tissuesections for rapid, label-free cancer margin detection

    Master-uppsats, Linköpings universitet/Institutionen för medicinsk teknik

    Författare :Merel Younan; [2023]
    Nyckelord :SFDI; transillumination SFDI system; tissue-conserving surgeries; thin layers; tissue analysis; skin cancer;

    Sammanfattning : This study investigates the potential of Spatial Frequency Domain Imaging (SFDI) as a non-invasive imaging technique for tissue analysis in the context of Mohs surgery, a standard procedure for skin cancer removal with margin control. The current practice of performing multiple histopathologic sections during the procedure is time-consuming and labor-intensive. LÄS MER

  7. 5. UPPVÄRMNINGSÅTGÄRDER VID LAPAROSKOPISK KIRURGI : - En integrativ litteraturstudie

    Magister-uppsats, Mälardalens universitet/Akademin för hälsa, vård och välfärd

    Författare :Gabriela Simon; Diana Patricia Ramirez Vargas; [2022]
    Nyckelord :To prevent hypothermia; nursing procedures; perioperative care; perioperative hypothermia; warming techniques; laparoscopic surgery; Att förebygga hypotermi; omvårdnadsåtgärder; intraoperativ omvårdnad; uppvrmningsåtgärder; laparoskopisk kirurgi;

    Sammanfattning : Patienter som genomgår laparoskopiska ingrepp sövs med anestesiläkemedel och behöver administration av intravenösa vätskor och inblåsning av koldioxidgas i bukhålan under operationen. Ju längre anestesitid och ju längre tid det laparoskopiska ingreppet tar desto större är risken att patienter drabbas av perioperativ hypotermi. LÄS MER
