The transferability of a measurement protocol from one laboratory to another is an important feature of any mature, standardised protocol. The electron paramagnetic resonance (EPR)-tooth dosimetry technique that was developed in Scientific Center for Radiation Medicine, AMS, Ukraine (SCRM) for routine dosimetry of Chernobyl liquidators has demonstrated consistent results in several inter-labora...

As healthcare delivery systems and technology continue to evolve, the role and responsibilities of the medical dosimetrist need to be delineated. The Scope and Standards of Medical Dosimetry Practice is design to provide a statement of competence in medical practice; define the practice of medical dosimetry; and provide a useful guide for medical dosimetrists and others in evaluating the qualit...

This study analyses the thermally stimulated luminescence or thermoluminescence (TL) glow curve between 300 and 773 K of germanium-doped silica optical fibre. A main glow peak at 530 K with a characteristic spectral emission centred at 400 nm is found. Both features are particularly suitable for dosimetry. Thus, an investigation by the TL technique of some first clinically relevant features of ...

A method for evaluating the overall uncertainty of alanine EPR transfer dosimetry in the therapeutic dose range is described. The method uses experimental data on EPR signal reproducibility from replicate dosimeters irradiated to low doses (1-5 Gy), estimates of Type B uncertainties, and Monte Carlo simulations of heteroscedastic orthogonal linear regression. A Bruker ECS106 spectrometer and Br...

introduction: the aim of the present study was to investigate the effects of srp assisted by the two clinical treatment methods of diode laser or chlorhexidine gel applications in comparison with srp alone. methods: eight patients with moderate to severe chronic periodontitis, each with at least three pockets 4–7 mm deep, were selected for this study. over 66 pockets were selected and randomly ...

introduction: the aim of this study was to compare the antibacterial efficacy of diode laser 810nm and photodynamic therapy (pdt) in reducing bacterial microflora in endodontic retreatment of teeth with periradicular lesion. methods: in this in vivo clinical trial, 20 patients who needed endodontic retreatment were selected. after conventional chemo mechanical preparation of root canals, microb...

introduction: to improve laser hair removal (lhr) for dark skin, the fluence rate reaching the hair follicle in lhr is important. this paper presents the results of a comparative study examining the function of wavelength on dark skin types using 755 nm alexandrite and 810 nm diode lasers. methods: the structure of the skin was created using a realistic skin model by the advanced systems analys...

background: intraoperative radiation therapy (iort) technique is used to treat a surgically exposed tumor or tumor bed in the treatment of locally advanced intraabdominal, retroperitoneal, pelvic, thoracic, breast and soft tissue tumors. one way to perform iort is to use an existing linac and modify the treatment head using an applicator system. in this study the objectives were to design, and ...
