Fruit MRI

Splashery stretches a drumhead over this Splash's outline, twelve inches across, and finds the ways it can ring. Its lowest is 277.1 Hz, 99 cents sharp of C4, the nearest tine on the comb. The next fifteen are its overtones, and each one draws its own figure: sand gathers on the lines that stay still.

Drag on the fruit or move the Slice slider to step through the slices. Tap to play them all; a drag stops it.

An MRI scanner (magnetic resonance imaging) uses no X-rays. A strong magnet lines up the hydrogen nuclei in the water of the fruit, radio pulses tip them over, and the radio signal they give back as they relax is turned into a picture, one thin slice at a time. In this T2-weighted look, watery tissue is bright, while seeds, skin and air are dark.

The kiwi and the orange here are built for the splash to look like real MRI slices: the kiwi's ring of black seeds in its bright locules around a pale core, the orange's segments with thin walls between them and its peel. Choose the fruit and the vision (the realistic gray, night vision or infrared) in the Splash tab. The faint outline of the whole fruit and the thin ring round each slice show where the slice is.

Made in Splashery. Its code is MIT.
