Researchers in the UK have developed a way to coax microscopic particles and droplets into precise patterns by harnessing the power of sound in air. The implications for printing, especially in the fields of medicine and electronics, are far-reaching. The scientists from the Universities of Bath and Bristol have shown that it's possible to create precise, pre-determined patterns on surfaces from aerosol droplets or particles, using computer-controlled ultrasound. A paper describing the entirely new technique, called 'sonolithography', is published in Advanced Materials Technologies.
How Accurate Is An Ultrasound In Determining Age Of Fetus?
How Accurate Is Your Due Date By Ultrasound? – From conception to birth
Gestational age, synonymous with menstrual age, is defined in weeks beginning from the first day of the last menstrual period LMP prior to conception. Accurate determination of gestational age is fundamental to obstetric care and is important in a variety of situations. For example, antenatal test interpretation may be dependent on gestational age. Again, inaccurate assessment of gestational age will lead to errors in assessing the severity of fetal sensitization by the delta OD Fetal growth assessment, either clinically or by ultrasound evaluation, also relies on accurate assessment of gestational age. Fetal growth retardation or macrosomia may be missed or incorrectly diagnosed owing to errors in gestational age assignment. Interpretation of antenatal biophysical testing non-stress tests and biophysical profiles may be subject to variation with gestational age as well.
The researchers applied an ultrasound examination protocol covering 12 lung regions in COVID patients undergoing treatment at HC. The results showed that the higher the lung ultrasound score, the greater the risk of admission to an intensive care unit ICU , intubation, and death. It can be a simple, cheap way to estimate the prognosis for patients infected by the virus," Souza told. At the start of the pandemic, Souza and other emergency room ER attendings at HC and other hospitals worldwide had to process overwhelming numbers of patients with insufficient resources.
