Embodiment Construction

[0037] The presently claimed invention provides a novel system for indicating target radiation areas which will be adapted to use light fields (as previously described in relation to figure 1 The known target indication methods described in ) are not suitable or provide strong disadvantages for diagnostic or therapeutic radiology systems. The claimed novel systems and methods are primarily illustrated with respect to phase-contrast imaging systems, but the skilled artisan will know how to adapt the described embodiments to other imaging or treatment applications having the same or similar problems as phase-contrast imaging systems used in radiology systems.

[0038] The presently claimed invention is based on the insight that instead of using a single beam generator used in conjunction with a radiation beam collimator arrangement, it is possible to couple two light field generators decoupled from the radiation beam path and each having a different beam direction to generate a...

Abstract

The present invention relates to a system and method for indicating a desired target radiation area of a radiation beam from a phase contrast radiology system on a subject. The system comprises a first light field generator and a second light field generator to project the light fields on the subject. Both light fields are decoupled from the path of the radiation beam. The overlapping area of bothlight fields indicates the target radiation area. The light fields do not substantially match the radiation beam path.

Description

technical field [0001] The present invention generally relates to a system and method for indicating a desired target radiation area of ​​a radiation beam of a phase contrast radiology system on a subject, and a method for using a radiation beam of a phase contrast radiology system on a subject. An imaging system for irradiating an object over a targeted irradiation area. Background technique [0002] Before a medical radiation procedure (e.g., a diagnostic or therapeutic radiation procedure), the desired target area to be irradiated needs to be indicated on the object in order to align the radiation beam so that the radiation beam irradiates the relevant region in the object (e.g., organs in the patient), and avoid irradiating areas that should not be exposed to radiation. [0003] In most radiation procedures, target indication is provided using a light field indicator that projects an optical light field onto the subject that is shaped so that it corresponds to The area...
