2. 1. Conventional spiral and low-dose computed mandibular tomography for dental implant planning

   Author : Annika Ekestubbe; Göteborgs universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Artifacts; Dental Implantation; Endosseous; methods; Dental Implants; Humans; Jaw; Edentulous; radiography; Mandible; radiography; Patient Care Planning; Phantoms; Imaging; Radiation Dosage; Radiography; Dental; methods; Reproducibility of Results; Tomography; X-Ray; instrumentation; methods; Tomography; X-Ray Computed; methods;

   Abstract : Absorbed doses to radiosensitive organs in the head and neck from pre-implant conventional hypocycloidal, conventional spiral and computed tomography (CT) were measured with thermoluminescent dosimeters in an anthropomorphic phantom head. From conventional tomography organ doses, except to the major salivary glands, were below 0.2 mGy. READ MORE

4. 2. Photon Counting X-ray Detector Systems

   Author : Börje Norlin; Christer Fröjdh; Hans-Erik Nilsson; Kenway Smith; Mittuniversitetet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Monte Carlo simulation; Three-dimensional; Energy weighting; X-ray; Pixel detector; Charge sharing; Imaging; Medipix; Spectroscopy; Dental diagnosis; Image quality; Electronics; Elektronik;

   Abstract : This licentiate thesis concerns the development and characterisation of X-ray imaging detector systems. “Colour” X-ray imaging opens up new perspectives within the fields of medical X-ray diagnosis and also in industrial X-ray quality control. READ MORE

5. 3. Characterisation and application of photon counting X-ray detector systems

   Author : Börje Norlin; Christer Fröjdh; Hans-Erik Nilsson; Sherwood Parker; Mittuniversitetet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Monte Carlo simulation; Three-dimensional; X-ray flouriscence; Charge transport; Semiconductor materials; Image sensors; CdTe; Photon counting; Synchrotron radiation; Material recognition; X-ray; Pixel Detector; Silicon; Charge sharing; Imaging; Medipix; Spectroscopy; Dental diagnosis; Image quality; Energy weighting; Electronics; Elektronik;

   Abstract : This thesis concerns the development and characterisation of X-ray imaging systems based on single photon processing. “Colour” X-ray imaging opens up new perspectives within the fields of medical X-ray diagnosis and also in industrial X-ray quality control. READ MORE

6. 4. Quality Aspects of Digital Radiography in General Dental Practice

   Author : Kristina Hellén-Halme; Malmö högskola; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Digital radiography;

   Abstract : POPULÄRVETENSKAPLIG SAMMANFATTNINGDet övergripande syftet med denna avhandling var att klargöra hur digital röntgenteknik används hos allmäntandläkaren och framför allt har syftet varit att undersöka kvaliteten hos röntgenbilderna och hur den skulle kunna förbättras. I det första arbetet studerades digitala röntgenbilder som var inskickade i samband med förhandsprövningar till Försäkringskassan. READ MORE

7. 5. Temporomandibular joint imaging using cone-beam computed tomography

   Author : Durer Iskanderani; Reinhilde Jacobs; Malmö universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

   Abstract : Cone-beam computed tomography (CBCT) is one of the most revolutionary innovations in dentistry, and was introduced into the dental field two decades ago as a three-dimensional (3D) imaging modality. Since then, it has gained general clinical acceptance, and is widespread among many dental specialties. READ MORE
