1. 1. EVALUATION OF RADIATION DOSES USING CONE BEAM COMPUTED TOMOGRAPHY IN ENDOVASCULAR AORTIC REPAIR AND SCOLIOSIS PROCEDURES

   University essay from

   Author : Louise Strandberg; [2021-04-06]
   Keywords : Medical physics; Cone beam CT; CT; EVAR; scoliosis; radiation dose; effective dose;

   Abstract : Purpose: The study includes the two areas, vascular surgery and orthopedics, and focuses on endovascular aortic aneurysm repair (EVAR) and scoliosis procedures. EVAR procedures contribute to a high radiation dose to the patient and for scoliosis procedures, it is often young girls that are undergoing surgery. READ MORE

3. 2. Development of methods and software for rapid quality control in fluoroscopy

   University essay from Umeå universitet/Institutionen för fysik

   Author : Majid Khosamadi; [2021]
   Keywords : ;

   Abstract : Background: Fluoroscopy is a common imaging technique which uses X-ray to derive a real time imaging of patient anatomy to determine diagnosis and positioning of patients for interventional procedures. It is therefore important that the fluoroscopy systems maintain their performance. READ MORE

4. 3. Needle Navigation for Image Guided Brachytherapy of Gynecologic Cancer

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

   Author : Alireza Mehrtash; [2019]
   Keywords : Image Guided Surgery; Surgical Navigation System; Needle Navigation system; Brachytherapy; MRI; 3D Slicer;

   Abstract : In the past twenty years, the combination of the advances in medical imaging technologies and therapeutic methods had a great impact in developing minimally invasive interventional procedures. Although the use of medical imaging for the surgery and therapy guidance dates back to the early days of x-ray discovery, there is an increasing evidence in using the new imaging modalities such as computed tomography (CT), magnetic reso- nance imaging (MRI) and ultrasound in the operating rooms.

5. 4. Estimating patient peak skin dose with fluoroscopic procedures

   University essay from Umeå universitet/Institutionen för fysik

   Author : Max Hellström; [2018]
   Keywords : skin dose; radiation dose structured reports; interventional radiology; radiation dosimetry;

   Abstract : During image guided interventional radiology (IR) procedures, acute X-ray induced skin injuries may occur due to high absorbed patient skin dose. These procedures are highly dependent on X-ray imaging both for guiding fluoroscopy and high quality diagnostic image acquisitions. READ MORE

6. 5. Modeling of scatter radiation during interventional X-ray procedures

   University essay from Linköpings universitet/Avdelningen för radiologiska vetenskaper; Linköpings universitet/Medicinska fakulteten

   Author : Emelie Rehn; [2015]
   Keywords : medical staff; personnel; practitioner; staff exposure; physician; operator; occupational exposure; radiation protection; protection in medical x-ray imaging; x-ray exposure; radiation dose; radiation scatter; fluoroscopy; interventional x-ray procedures; interventional radiology; angiography; fluoroscopically guided procedures; interventional radiology dosimetry; interventional cardiology dosimetry; catheterization interventions;

   Abstract : During catheterized x-ray interventions the patient and medical staff is exposed to scatter radiation, as a consequence of tissue interactions. Ionizing radiation for medical purpose is potentially dangerous and can cause malignancy, skin damage and more. READ MORE
