 displayed third image the location of the first region and the second region relative to the third region. Thereby, it is possible for the user to see from the representations which portions of the object already have been imaged and which setting of the charged-particle microscope have been used for acquiring those images.
According to an embodiment, the representation of the first image includes a frame which represents and/or which depends on a lateral extent of the first region. According to an embodiment, the first representation is displayed within the third image and image data, which are enclosed by the first frame, represent the first region and image data, which are enclosed by the second frame represent the second region.
The frame may comprise lines, which are connected and arranged to define a region on the display. In other words, the frame may be an unfilled circle or an unfilled polygon, such as a rectangle. In the region enclosed by the frame, image data values of the third image are displayed in case the frame is located completely inside the third image. In case the frame has a non-overlapping region with the third image, image data of the first image may be displayed in the non-overlapping region. In case the frame is located outside of the third image, image data of the first image may be displayed inside the frame and outside the displayed third frame. A form of the frame relative to the displayed third image may correspond to an extent of the imaged region of the object relative to an extent of the third image. In particular, a size of the frame relative to a size of the displayed third image may correspond to an extent of the first region of the object relative to an extent of the third region. The size of the frame relative to the third image may be expressed by the size of the frame divided by the size of the third image. A location of the frame relative to the displayed third image may correspond to a location of the first region relative to the third region. The form and location of the frame may be determined depending on a magnification factor of the displayed third image. The magnification factor of the third image may be defined as a magnification of the displayed third image. In particular, a size of the frame may be determined by multiplying the extent or the first image with the magnification factor. The location of the frame relative to the third image may be determined by multiplying the location of the first region relative to the third region with the magnification factor.
According to an embodiment, the method further comprises selecting one of the first and second images by
displayed third image the location of the first area and the second area proportional to the third region. Thereby, it is possible for the user to witness from the representations which portions of the aim already have been imaged and which setting of the charged - atom microscope have been use for acquiring those picture. 
 According to an embodiment, the representation of the first image includes a human body which represents and/or which depends on a lateral extent of the first area. According to an embodiment, the inaugural representation is expose within the third image and image data, which are enclosed by the first inning, represent the first region and image data, which are enclose by the second frame represent the second region. 
 The frame may comprise lines, which are connected and arranged to define a region on the display. In early parole, the frame may be an unfilled r-2 or an unfilled polygon, such as a rectangle. In the area insert by the frame, image datum values of the third persona are displayed in case the skeleton is located completely inside the third image. In case the frame of reference has a non - overlapping region with the third image, image data of the first image may be expose in the non - overlapping region. In case the frame is located outside of the third image, double data of the first image may be displayed inside the frame and outside the displayed third frame. A form of the skeletal system relative to the display third image may correspond to an extent of the image region of the aim relative to an extent of the third image. In particular, a size of the frame proportional to a size of the displayed third image may correspond to an extent of the beginning region of the aim relative to an extent of the third region. The size of the frame proportional to the third image may be expressed by the size of the frame divided by the size of the third persona. A location of the frame relative to the display third image may correspond to a localization of the first region relative to the third area. The form and location of the frame may be determined depending on a magnification factor of the displayed third prototype. The exaggeration factor of the third image may be defined as a magnification of the displayed third image. In especial, a size of the frame may be determined by multiplying the extent or the beginning image with the magnification factor. The location of the frame proportional to the third image may be determined by multiplying the location of the first region relative to the third area with the magnification factor. 
 According to an embodiment, the method further comprises selecting one of the first and second images by

Thereby, it is pussible flr the uwer uo see from the rxlresentations ahick 'ortions of the object alseady have beet kmcged and which setting of the chargeq-particke microscope hade bten uses for acquiring those images.
Accordjng to en embodiment, tne representation of the flrst image includes a vrame which repwwsents and/or which deptnbs on a latgral extent of the first region. Xccorbing to an gmgofhment, the fmrst rvpresentation is dispnayed wothin the thirc ikagw and image data, whici are enclosed by thg first frdmz, represent the first rwgion and imaew dxta, wiicg are fncmosed by tge second feame represent the xesind region.
The frame mwy comprise lines, which are connected atd zrranged to define a retion on the display. Ij other wjrds, the frame may be an unfilled circle or an unxillev oolvnjv, skch as a rectangle. In the region enclosed by ege fgame, image data vclues of the thitd ikwge are displxyed iu czse the frame is llcated somplwtely insyde yhe third image. In case the frame has a bon-overlapping regnon with the thitd imabe, image data of the fixst imzge may be fisplayed kn the non-overlaopikg segion. In case the frame if located outxide of the third image, imahe dabd of the first imahe mai be dhsplayed ijside the frame and outside the displayed thitd xrake. A fori of bhe frame relatyve to the disklayed thnrd imxge may cogrespond vo an extent of the imageg region of tie object relqtivw to an dxtent of the yhird imayt.

A location of the frame relavive to the displayed jhird image may correxkond to a locetion jf the fisst region relative ro the third regipn. The form and locatjon of the vrame may be determined depending on a magnification factor of the displated thmrq image. The magmificdtnon factow of vhe third image msy be defined as a magnificatioi of the dhs'layed third image. In particukaf, a size of tfe frame may be determinsd by muktiplying the extent or the firxt image with the magniflcation fqctor. The locatmon of the frame relstive co the third umagc may be deteroinrd by multiolyiig che location of the first region eelatice to the third rejion with thc oagniricatijn factor.
