Provided is an X-ray fluoroscope that has a short imaging time, suppresses overlapping of images of components in a width direction, and can obtain sufficient sensitivity even in a case of an X-ray source having insufficient X-ray intensity. The X-ray fluoroscope (10) comprises: an X-ray source (1) that irradiates with radial X rays (2); a sample holder (5) that holds a sample so that the surface of the sample (3) is irradiated with the radial X-rays; a planar CCD (6) in which a CCD that receives the X-rays transmitted through the surface of the sample is disposed in a planer shape at a location separated from the sample holder when viewed from the X-ray source, and which obtains an X-ray transmission image of the surface of the sample; and a moving unit (7) that allows the sample holder and the planar CCD to move relative to each other in synchronization with imaging by the planar CCD, wherein the planar CCD has 500 pixels or more in a direction of the relative movement with respect to the sample.

A void evaluation apparatus in a solder includes an evaluation function calculation unit for calculating a solder evaluation function by using a pixel value pi contained in the voids that is set to 1 and the pixel value pi not contained in the voids is 0 for each pixel constituting an image in the solder, and by using a weight function w(ri), which is maximum at a solder center (ri=0), and is 0 at a maximum radius (ri=r0) for a distance ri from the solder center. The apparatus further has a void evaluation unit for evaluating that the influence of voids is larger as the evaluation function is relatively larger for the each solder.
w(ri): weighting function

IMAGE RECONSTRUCTION DEVICE, IMAGE RECONSTRUCTION METHOD, AND PROGRAM
Starting at a given pixel point in a raw image and moving along a straight line that extends from said pixel point, a discrimination-region inference unit (112) searches for edges, and on the basis of the change in pixel values that occurs at the first detected edge, infers which of a number of discrimination regions the pixel point in question belongs to. A discrimination-region determination unit (113) counts how many times the discrimination-region inference unit (112) infers the pixel point in question to belong to each discrimination region using a large number of straight lines extending in different directions and determines the pixel point in question to belong to the discrimination region to which said pixel point was inferred to belong the greatest number of times. An image generation unit (114) generates a reconstructed image in which, for each pixel point in the raw image, a color corresponding to the discrimination region that the discrimination-region determination unit (113) determined said pixel point to belong to is used at the location of said pixel point.
An apparatus for assessing voids in solder comprises: a function calculation unit that processes the pixels constituting an image of the interior of a piece of solder such that the pixels in the voids have a pixel value pi of 1 and the pixels not in the voids have a pixel value pi of 0 and uses a weighting function w (ri) for the distance ri from the center of the piece of solder, the maximum of the function being at the center of the piece of solder (ri = 0) and the minimum being at the maximum radius (ri = r0), to calculate the following void assessment function, where i represents pixel number (1-N), pi represents pixel value (0 or 1), and w(ri) represents the weighting function; and a void assessment unit which performs assessment for each piece of solder in a manner such that the greater the relative size of the assessment function the greater the influence of the voids.
