1. 1. Indocyanine-green fluorescence imaging to detect anastomotic insufficiency after esophagectomy

   University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Förbränningsfysik

   Author : Love Kildetoft; [2024]
   Keywords : Fluorescence; Imaging; Indocyanine-green; ICG; Esophageal cancer; Physics; Photonics; Image Analysis; Blood Perfusion; Anastomotic leakage; Anastomotic insufficiency; Physics and Astronomy;

   Abstract : This research project is concerned with the development of simulation models and image analysis algorithms, as well as instrumentation for characterizing anastomotic leakages after a patient has undergone surgery for esophageal cancer. Anastomotic leakage is a high-incidence complication after esophagectomy, a surgical procedure for esophageal cancer. READ MORE

3. 2. Monte Carlo evaluation of static and dynamic 6FFF treatments - Evaluation of dose distributions calculated with AAA, Acuros XB, and Collapsed Cone (RayStation and DoseCheck)

   University essay from

   Author : Alma Blombäck; [2023-02-23]
   Keywords : Medical physics; Monte Carlo; 6FFF; AAA; Acuros XB; DoseCheck; RayStation; DVH evaluation; flattening filter free;

   Abstract : There are several benefits to removing the standard flattening filter and using so-called flattening filter free (FFF) treatments in external radiation therapy with photons. The main advantage is the possibility of significantly shortening the treatment time, de spite this FFF is not widely used yet. READ MORE

4. 3. Development of a new SBRT dose planning strategy for thoracic tumours in RayStation

   University essay from Umeå universitet/Radiofysik

   Author : Olof Westman; [2023]
   Keywords : radiotherapy sbrt lung robust; radioterapi;

   Abstract : Umeå University Hospital has acquired a new treatment planning system, RayStation, for radiotherapy. It has a different set of dose calculation algorithms that require new planning strategies for stereotactic lung cancer treatments. READ MORE

5. 4. GPU-Based Path Optimization Algorithm in High-Resolution Cost Map with Kinodynamic Constraints : Using Non-Reversible Parallel Tempering

   University essay from Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

   Author : Daniel Greenberg; [2023]
   Keywords : ;

   Abstract : This thesis introduces a GPU-accelerated algorithm for path planning under kinodynamic constraints, focusing on navigation of flying vehicles within a high-resolution cost map. The algorithm operates by creating dynamically feasible initial paths, and a non-reversible parallel tempering Markov chain Monte Carlo scheme to optimize the paths while adhering to the nonholonomic kinodynamical constraints.

6. 5. Implementation and evaluation of the Heston-Queue-Hawkes option pricing model

   University essay from Uppsala universitet/Sannolikhetsteori och kombinatorik

   Author : Samuel Rosén; [2023]
   Keywords : HQH; Heston Queue Hawkes; Option Pricing; jump diffusion;

   Abstract : Introduction: This thesis presents a python implementation and evaluation of the Heston-Queue-Hawkes (HQH) model, a recent jump-diffusion model for pricing options. The model is capable of tracking options for a wide range of different underlying assets. READ MORE
