The third scale starts at the head of the pointer 20.

In the actual molybdenum target inspection process, two body positions are adopted for molybdenum target inspection shooting, one is a vertical position, the other is an oblique position, after the shooting is finished, the focus needs to be positioned on a molybdenum target film, and the method specifically comprises the following steps:

on a molybdenum target film in a vertical position, aligning the center of an auxiliary positioning strip 30 with the center of the root of a human nipple, enabling the human nipple to correspond to a space enclosed by the auxiliary positioning strip 30 and a straight strip body 12, then, taking the center of the root of the human nipple as a starting point and taking the straight line direction vertical to the edge line of the film where a gap is positioned towards the back of a breast as a reference positioning line of an auxiliary positioning rod 40, namely, the auxiliary positioning rod 40 is overlapped with the vertical straight line for positioning, shifting a pointer 20 to the position with the maximum diameter of a focus, marking two vertexes positioned at the position with the maximum diameter by using a marking pen, drawing two parallel lines vertical to the pointer 20 through the two vertexes respectively, and recording scale values corresponding to the two parallel lines;

then, on the molybdenum target film in the inclined position, in the same way, the center of the auxiliary positioning strip 30 is aligned with the center of the root of the nipple of the human body, and the nipple of the human body corresponds to the space surrounded by the auxiliary positioning strip 30 and the straight strip body 12, then, the straight line direction which is perpendicular to the edge line where the pectoralis major is located with the center of the root of the nipple of the human body as the starting point is taken as the reference positioning line of the auxiliary positioning rod 40, that is, the auxiliary positioning rod 40 is coincident with the perpendicular straight line for positioning, the pointer 20 is shifted to the position with the maximum diameter of the focus, two vertexes located at the position with the maximum diameter are marked by the marking pen, two other parallel lines perpendicular to the pointer 20 are drawn through the two vertexes respectively, and the scale values corresponding to the other two parallel lines are recorded;

therefore, the specific position of the focus on the molybdenum target film can be determined through two groups of parallel lines.

Then, marking two parallel lines on the human breast by adopting the vertical position adopted when the human body shoots the molybdenum target film and adopting the same positioning mode and the same scale value as the molybdenum target film at the vertical position; marking the human body with another two parallel lines on the human breast by adopting the oblique position adopted when the molybdenum target film is shot and adopting the same positioning mode and the same scale value as the oblique molybdenum target film;

therefore, the two groups of parallel lines, namely the four parallel lines can define the specific position of the focus at the breast of the human body.

The positioning device can firstly measure on the molybdenum target film and position the focus, then according to the measured angle and distance, the corresponding angle and distance are marked from the breast by adopting the same body position as the molybdenum target during examination, and the ratio of the molybdenum target film to the breast is 1:1. this kind of positioner need not to carry out the pad pasting on human breast, simple structure, and the using-way is simple, convenient, and repeatedly usable, greatly the cost is reduced, has improved the efficiency of focus location, and uses through location body 10 and the cooperation of pointer 20, and first scale, second scale and third scale cooperation are used, and the precision is higher.

The foregoing is only a preferred embodiment of the present invention, and therefore the scope of the invention should not be limited by this, and the equivalent changes and modifications made in the claims and the description should be considered within the scope of the present invention.
