Shunt scintigraphie

Scintigraphy (from Latin scintilla, "spark"), also known as a gamma scan, is a diagnostic test in nuclear medicine, where radioisotopes attached to drugs that travel to a specific organ or tissue (radiopharmaceuticals) are taken internally and the emitted gamma radiation is captured by external detectors (gamma cameras) to form two-dimensional images in a similar process to the capture of x … WebOct 30, 2024 · Normally 400-500A shunt should be enough. Probably even 300A. 1 or 0.5% measurements difference is still acceptable in that range. If I look at a shunt that is getting close to the bus-bar thickness, I'm looking at 1000-1500A shuts. At 1000A, 5 to 10A measure error, compared to 2.5-5A when 500A would have been used.
