Oblique lumbar spine films

Enhanced methanol sensing performance of oblique deposited WO3 thin films

Methanol (CH3OH) is a colorless liquid with a mild odor. The wide ranges of applications, toxicity and clinical implications of methanol have made necessary to develop reliable and high-performance methanol sensors. In this paper, WO3 thin films were deposited on SiO2/Si substrates by e-beam evaporation technique under normal and oblique angles and then post-annealed at 500 °C with a flow of ox...

Lumbar spine densitometry.

failure of antigen production is more likely to be due to genetic change associated with incomplete penetrance than to genetic loss. An alternative or additional possibility cannot, however, be excluded-that exuberant cell division causes dilution of a particulate cytoplasmic factor responsible for the formation of the antigen. Loss of organ-specific antigens could influence tumour metastasis b...

Beam Collimation during Lumbar Spine Radiography: A Retrospective Study

Introduction: Collimating the primary beam to the area of diagnostic interest (ADI) has been strongly recommended as an effective method to reduce patient’s radiation dose and to improve image quality during radiology practice. Lack or inadequate collimation results in excessive radiation dose to patients and deterioration image quality.Objective: To assess the quality of beam collimation dur...
