A scanning method, which is a method of identifying a change in the density of an object, includes arranging a source of ionizing radiation and an array of radiation detectors Dn, where n is an integer from 1 to N, capable of detecting the radiation in such a way that radiation counts are counted by the detectors as the source and detectors are rotated around the object. Detectors are arranged in conjugate pairs so that missing data due to a malfunctioning detector may be filled in from its conjugate.

A tilt adjusting image including a captured image that is obtained by capturing a wearer wearing a spectacle-type electronic device, and a horizontal line image indicating a horizontal direction identified by a tilt identification part, is displayed. The wearer adjusts a position of the spectacle-type electronic device by a wearer's hand or the like while viewing the tilt adjusting image so that the spectacle-type electronic device becomes horizontal. When the wearer judges that the spectacle-type electronic device has become horizontal, the wearer operates an operation part and inputs a calibration instruction. When the calibration instruction is input, the calibration instruction is transmitted to the spectacle-type electronic device.

The calibrating system 100 includes a conveyance system 102 for carrying work products 104 arranged in multiple lanes extending along the conveyor to be trimmed and/or cut into portions P. A scanner 110 scans the work product and a cutter system 120 consisting of one or more cutters are arranged in an array or series of cutter assemblies for cutting the work products into end pieces P of desired sizes or other physical parameters. A processor/computer 150, using a scanning program or portioning program, determines how the work product may be portioned into one or more end piece product sets. The processor/computer using the portioning software then functions as a controller to control the cutter system 120 to portion the workpiece 104 according to the selected end product/pieces P.

A method of checking or adjusting the calibration of a mass spectrometer is disclosed. The method comprises fragmenting parent or precursor ions and generating fragment or product ion mass spectral data and recognizing first neutral loss ions in the fragment or product ion mass spectral data. The method further comprises determining a first mass loss difference between the parent or precursor ions and the first neutral loss ions and determining whether the first mass loss difference corresponds with an expected or pre-determined mass loss difference, wherein if it is determined that the first mass loss difference does not correspond with an expected or pre-determined mass loss difference then the method further comprises adjusting one or more calibration parameters.

For calibration (24) for quantitative SPECT, a multiple energy emission source (11) is used for calibration. The planar sensitivities and/or uniformities are determined at different emission energies based on detections from the multiple energy emission source. For estimating (32) the activity concentration, sensitivities and/or uniformities based on measures (26) at different emission energies increase accuracy. The multiple energy emission source (11) may alternatively or additionally be used to calibrate (40) a dose calibrator (15).
