Symbol for the negative decadic logarithm of the H + ion concentration (measured in moles per liter); a solution with pH 7.00 (1 Ã 10 -7 g molecular weight of H +K per liter) is neutral at 22Â°C (that is, [H + ] = [OH - ]), one with a pH value of more than 7.00 is alkaline, one with a pH lower than 7.00 is acid.
For example, the cost of a CT scanner can be as low as $65,000 for a refurbished one that produces only small images quickly. A larger and brand new CT scanner can run as high as $2.5 million. Prices are slightly higher for MRI machines, running up to about $3 million for a new machine.Ultrasound machines are much cheaper at $10,000-$200,000, depending on brand and type. For hospitals and imaging centers, the base price for machines is just the beginning. larger and brand new CT scanner can run as high as $2.5 million.

1 In the past three years, NHS trusts in England have spent around Â£50 million. annually on purchasing three specific types of high value capital equipment â Magnetic. Resonance Imaging (MRI) and Computed Tomography (CT) scanners, used for. diagnosis, and Linear Accelerator (linac) machines for cancer treatment. The current. value of these three types of machines in the NHS is around Â£1 billion. The NHS. in England employs around 2,200 consultant radiologists and 12,000 diagnostic. radiographers, and a proportion of these will work with CT and MRI machines, but the. proportion is not known.
