For ease of understanding this utility model, operation principle of the present utility model is described earlier:
Shown in Fig. 2 a, A is the scanogram at the focus point place that obtains when CT scan checkout gear frame 100 tilts an angle [alpha], and this scintigram is generally to lie low to detect down at human body and obtains, and common plane, human body place is parallel with horizontal plane, wherein:
The O point is the focus point, is that initial point is set up three-dimensional coordinate XYZO with O: the axis of crossing the O point and being parallel to the human body y direction is defined as X-axis; Cross the O point, and axis that be positioned at scanning aspect A on vertical with X-axis is defined as Y-axis; Cross O point, vertical with Y-axis and be defined as the Z axle with axis that Y-axis is positioned on the same scanning aspect A.At this moment, the scanning aspect at focus point place is the YOZ plane.Wherein, the L point is the skin penetrating point, and LO is desired puncture needle path, and this segment distance is referred to as depth of needle; With the Z axle is the inserting needle benchmark, and the angle between straight line LO itself and the Z axle is called needle angle, and we are designated as θ to it; During detection, the frame of scanner usually can be carried out certain front or rear inclination around Y-axis, cross Y-axis do one with the vertical plane h in level ground, the angle between described YOZ plane and the h plane is the angle of inclination of CT frame, we count α to it.When α less than zero the time, the CT frame is a retroverted state; When α greater than zero the time, the CT frame is a forward-lean state; When α equalled zero, the CT frame was perpendicular to the level ground, and just perpendicular to detected human body, we are called zero degree.But as long as the frame of scanner is around the forward and backward inclination of Y-axis, after certain angle [alpha] that tilts, as the Z axle of inserting needle benchmark forever perpendicular to the y axle; Just, the face that constitutes around the track of the formed Z axle of the forward and backward inclination of Y-axis as the Z axle of inserting needle benchmark is perpendicular to Y-axis.
