1. A laser-based alignment assistance apparatus used to assist with alignment of an instrument for puncturing a subject, in particular for an X-ray imaging system, the laser-based alignment assistance apparatus comprising:
a first line laser to produce a first laser beam in a first laser plane, the first line laser being configured to produce a first laser line on a first surface line of the instrument in a first sectional plane of the instrument when the first sectional plane corresponds to the first laser plane; and
a second line laser to produce a second laser beam in a second laser plane intersecting the first laser plane;
a point-like shielding element of the second line laser to produce a shadow line in the second laser plane,
wherein the second line laser is configured to display a shadow point of the shadow line on a second surface line of the instrument in a second sectional plane of the instrument when the first sectional plane and the second sectional plane are aligned.
