Engineering and Physical Sciences in Medicine, Adelaide, 28 October 2018 I was delighted to convene this pre- conference workshop at the Royal Adelaide Hospital on behalf of the Australasian College of Physical Scientists and Engineers in Medicine. A full capacity audience heard presentations from leading local MR professionals- all with the focus of encouraging collaboration … More MR Physics Workshop
First choose the tissues you are interested in. Alternatively T1 and T2 values can be entered as “free”.Then select your scanning TR and TE (for spin echo).The graph shows the signal intensity (max = 1) for both tissues, the contrast and the relative contrast to noise ratio (CNR). The relative grey scale for the two … More MR signal and contrast calculator (SE)
Use the SNR and resolution calculator to investigate the effect of various parameter changes in MRI. The calculator reports the relative (to default parameters) SNR, pixel size and scan time. Reloading the page will restore the default values. Note: this works best on a computer. It will also work on Android and IOS mobile devices. … More SNR and resolution calculator
Firstly, thanks everyone who viewed or shared my online SAR and B1+rms calculator. Various comments made on the MRI Safety Facebook page made me realise further explanation is required. The SAR calculator is based upon a similar equation to that shown above. This itself is a highly idealised approximation to reality, so the calculator will give … More More on SAR and B1+rms
