1. 1. On Virtual Surgical Planning in Cranio-Maxillofacial Surgery

   Författare :Johanna Nilsson; Andreas Thor; Risto Kontio; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Virtual surgical planning. Computer assisted planning. 3D computer model. Orbital segmentation. Craniomaxillofacial surgery planning. Haptics.; Oral and Maxillofacial Surgery; Käkkirurgi;

   Sammanfattning : The complex three-dimensional (3D) anatomy of the cranio-maxillofacial (CMF) region makes surgery a challenging task. Virtual surgical planning (VSP) has the potential to increase accuracy, reproducibility and shorten operation time. LÄS MER

3. 2. Haptics with Applications to Cranio-Maxillofacial Surgery Planning

   Författare :Pontus Olsson; Ingrid B. Carlbom; Blake Hannaford; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; medical image processing; haptics; haptic rendering; haptic gripper; visuo-haptic co-location; vibrotactile feedback; surgery simulation; virtual surgery planning; cranio-maxillofacial surgery; Computerized Image Processing; Datoriserad bildbehandling;

   Sammanfattning : Virtual surgery planning systems have demonstrated great potential to help surgeons achieve a better functional and aesthetic outcome for the patient, and at the same time reduce time in the operating room resulting in considerable cost savings. However, the two-dimensional tools employed in these systems today, such as a mouse and a conventional graphical display, are difficult to use for interaction with three-dimensional anatomical images.

4. 3. Metal artifacts in computed tomography : impact of reduction methods on image quality and radiotherapy treatment planning

   Författare :Karin Andersson; Per Thunberg; Eva Norrman; Jan Persliden; Anders Tingberg; Örebro universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; computed tomography; metal artifacts; image quality; visual grading analysis; radiotherapy; proton therapy; hip prosthesis; dental implants;

   Sammanfattning : Degradation of image quality by metal artifacts is a common problem in computed tomography (CT) imaging, which can limit the diagnostic value of a CT examination and also introduce inaccuracies in radiotherapy (RT) treatment planning. In recent years, commercial metal artifact reduction (MAR) methods have been launched by several CT vendors. LÄS MER

5. 4. Modeling and Visualization for Virtual Interaction with Medical Image Data

   Författare :Fredrik Nysjö; Ingela Nyström; Filip Malmberg; Ingrid Carlbom; Alexandru C. Telea; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; medical image processing; volume rendering; haptic rendering; medical visualization; virtual surgery planning; Computerized Image Processing; Datoriserad bildbehandling;

   Sammanfattning : Interactive systems for exploring and analysing medical three dimensional (3D) volume image data using techniques such as stereoscopic rendering and haptics can lead to new workflows for virtual surgery planning. This includes the design of patient-specific surgical guides and plates for additive manufacturing (3D printing). LÄS MER

7. 5. CT with 3D-Image Reconstructions in Preoperative Planning

   Författare :Angeliki Dimopoulou; Anders Magnusson; Anders Persson; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; CT Angiography; 3D-image reconstructions; haemodialysis; AVF AVG; DIEP flap; surgery time; complicated renal calculi; PNL; true nonenhanced images; virtual nonenhanced images; CT Urography; Radiology; Radiologi;

   Sammanfattning : Computed tomography is one of the most evolving fields of modern radiology. The current CT applications permit among other things angiography, 3D image reconstructions, material decomposition and tissue characterization. CT is an important tool in the assessment of specific patient populations prior to an invasive or surgical procedure. LÄS MER
