How do you choose equipment for imaging from the bewildering and tempting array of alternatives, particularly when your budget is limited ? The rules for shopping for images are the same as those for shopping in a supermarket: have a clear idea of what you need, and remember that cheapness may be a false economy. Imaging for the non-radiologist in a small hospital means diagnostic x ray equipme...

conclusion according to our findings, ct-guided percutaneous drainage is a safe and effective procedure in the treatment of abdominal abscess and fluid collection. results the average age of the patients was 54 years (range 12 to 79), including 21 (51%) men and 20 (49%) women. the common signs and symptoms were pain (83%) and fever (80.5%). the most prevalent abdominal abscess etiology was prev...

 ABSTRACTBackground: An electron beam generated X-ray spectrum consists of characteristic X-ray and continuous bermsstrahlung. The aim of this research is calculating and comparing X-ray spectra for different target filter of mammograms. Materials and Methods: Monte Carlo is a very powerful tool to simulate a series of different target-filter assembly in order to calculate the X-ray spectra. MC...

Introduction: Unfolding X-ray spectrum is a powerful tool for quality control of X-ray tubes. Generally, the acquisition of the X-ray spectrum in diagnostic radiology departments is complicated and difficult due to high photon flux. Measurement of x ray spectra using radiation detectors could not be performed accurately, because of the pulse pile up. Therefore, indirect methods...

The aim of this study was to evaluate the interfractional prostate motion of patients immobilized in the prone position using a thermoplastic shell. A total of 24 patients with prostate calcifications detectable using a kilo-voltage X-ray image-guidance system (ExacTrac X-ray system) were examined. Daily displacements of the calcification within the prostate relative to pelvic bony structures w...

Multidetector Computed Tomography (MDCT) technology plays an important role in the evaluation of injured patients. At our institution pelvic X-ray (PXR) is obtained routinely on trauma patients. Many also receive MDCT of the abdomen and pelvis for other indications. We hypothesized that there would be a substantial cost savings in adopting a policy of deferring PXR in a hemodynamically normal p...

The influence of sex on bone mineral density (BMD) and the bone mineral content (BMC) have been analysed in selected bones of the thoracic and pelvic limbs of African ostriches. The examination was conducted with the use of a densitometer, using the technology of affinited beam of X-ray and the programme for animal research. It was shown that the analysed bones of ostrich skeleton differed sign...

If diagnostic imaging during pregnancy is performed, potential risks not only for the mother but also for the fetus have to be considered. Ultrasonography should be performed primarily because it is harmless for the fetus. Other imaging modalities like x-ray, computed tomography (CT) and magnetic resonance imaging (MRI) should be reserved for cases in which results of ultrasonography are inconc...
