Fiber optic taper (FOP) array coupled digital x-ray detector can be an ideal choice for large area high resolution x-ray imaging, but its data acquisition system is a challenge, for the reasons such as restrictions of hardware design due to the shape of the FOP array, long distance control requirement in x-ray environment, and arrangement of data transmission sequence among multiple CCD/CMOS im...

We report our experimental results of measurements of x-ray attenuation coefficients of aqueous solutions of a light absorbing dye, indocyanine green, and an immunoadjuvant, glycated chitosan. In the treatment of metastatic tumors in rats using a novel laser immunotherapy these solutions were administered in situ. The x-ray attenuation data of the solutions are essential to development of an x-...

background and aims. radiography is used to diagnose the demineralization process and carious lesions; however, conventional radiography and direct digital images do not show these lesions when the amount of demineralization is less than 40%. digital subtraction radiography has recently been used to improve the diagnostic quality of these lesions. the purpose of this study was to compare the ca...

UNLABELLED This article presents general principles and a sample case of application of digital subtraction of x-rays for objective evaluation of results of treatment in dentistry. PURPOSE Evaluation of the results of surgical periodontal treatment by means of digital subtraction of radiographic images taken before and 12 month after surgery. MATERIAL AND METHODS For evaluation of the resul...

IntroductionA fine balance of image quality and radiation dose can be achieved by optimization to minimize stochastic and deterministic effects. This study aimed in ensuring that images of acceptable quality for common radiographic examinations in digital imaging were produced without causing harmful effects. Materials and MethodsThe study was conducted in three phases. The pre-optimization inv...

UNLABELLED The aim of this study is to assess the impact of multiparametric MR imaging to an exact determination of the extent of invasive ductal and lobular breast cancers in routine clinical practice.180 women aged 27-74 years (median 52.4 years) with newly diagnosed invasive ductal and lobular breast cancers confirmed by core-cut or vacuum-assisted biopsy were examined by all three imaging m...
