I.e., device X-ray images (100) upon ball number of X-ray images the object of interest non object of interest and dynamically monitoring sets a region of interest and non region of interest, object object of interest and non minimum X-ray is irradiated into penetration hole while moving up and down.

One also in the embodiment according to Figure 24 shows a non interest area setting method to explain the order. 19 as shown in also position tracking device (300) is provided when, position tracking device (300) for tracking non-object of interest (U) obtained by location information by region of interest non by an electrochemical reaction can establish a physical-layer connection KIPO & (UR).

Also refers to surface 24 and 19, X-ray images device (100) a non-object of interest (U) is detected. a CPU judges whether the (601). Device X-ray images (100) between that obtained with the embodiment in X-ray images is detected object of interest (U). Non (U) for the detection of object of interest, in X-ray images is characteristic of object of interest (U) or pre-stored, in a certain X-ray images the marker is subject is attached to (ob) may be proposed. In other words, device X-ray images (100) the X-ray images pre-stored in the a or just a particular features an region having to navigate and whether the, pre-stored features or just a particular pattern when there is a non-object of interest (U). detecting any passengers in an.

Non object of interest (U) when detector detects a (601 of no), device X-ray images (100) position of a non-object of interest (U). collects information. Position information for locating an object of interest (U) by a location tracking device (300) can be obtained by. Position tracking device (300) a magnetic field tracking method (magnetic tracking system) or optical tracking method (optical tracking system) said non interest during into one way impulses towards the location of the objects by tracking the conditional expression, and acquires position information can be.

Device X-ray images (100) has based on location information camera area non object of interest (FOV) (U) a prediction prediction entry (603). Specifically, non object of interest (U) or mobile direction of movement of object of interest, such as speed of vertical flow or horizontal flow (U) non-motion information of object of interest (U), for example, to predict a KIPO & movement of.

Non object of interest (U) photographing area when a entry (FOV) (examples of 603), device X-ray images (100) a non-object of interest (U) the non-regions which are expected to checks pre-of (UR) set a region of interest (604). Non object of interest (U) photographing region (FOV) member from entering the inside after region of interest (UR) when a listener sets a three-non, non object of interest (U) instantaneously, a a strong dose of X-ray can be exposed to KIPO &. Therefore, device X-ray images (100) a non-object of interest (U) photographing region (FOV) in region of interest prior to entering (UR) sets a non object of interest (U) minimizing exposure of a sprayer to the pesticide of penetration hole while moving up and down.

Non object of interest (U) detecting unit detects (examples of 601), device X-ray images (100) a non-object of interest (U) a prediction movement of (605). Non object of interest (U)X-ray images to predict movement of device (100) non detected object of interest (U) by tracking the, non direction of movement of object of interest (U). determining a rate of and a mobile. And, non object of interest (U) position prediction of the movement of the tracking device (300) (U) obtained in non object of interest using information on the position of the mobile may be. Specifically, a non-successively collected object of interest (U) based on the location information of non direction of movement of object of interest (U) and determining a rate of and a mobile, non using the same prediction movement of object of interest (U) may be loaded with.

Device X-ray images (100) has predicted non on the basis of the result of region of interest (UR) sets the (607). The, non position of region of interest (UR), size, and shape (U) position of object of interest a non, size, shape, based on the characteristics of motion such as may be determined, non movement of object of interest (U) a non-area where a region of interest (UR) .can be established.

On the other hand, device X-ray images (100) has region-of-interest (ROI) and the non-overlapping ranges of region of interest (UR) can be determines whether (609). Region of interest (ROI) (UR) region of interest and the non the set region of interest (ROI) the correct X-ray moving picture to obtain an application cannot be bar, device X-ray images (100) (UR) of interest and a non-region of interest (ROI) is stacked on an region can be used for checking a.

Region of interest (ROI) and the non-overlapping ranges of region of interest (UR) when (examples of 609), device X-ray images (100) has region-of-interest (ROI) not overlapping a non-region of interest (UR). capable of modulating (610).

On the other hand, device X-ray images (100) in Figure 24 invention as described above wherein the region of interest (ROI) non only in other region than the region of interest (UR) .may be used to establish a. As such background region (BR) region of interest non only when is set (UR) 609 and 610 can be a process comprises the dimerization of.
