Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
This is a prospective, single-center, non-randomised, non-blinded trial with Tomosyntheis of Patients referred to the investigators institution to assess lung alterations and bone structure. All patients will undergo chest x-ray and tomosynthesis after informed consent. In addition they will undergo an ultralow-dose CT, wich is used as standart reference. The radiation dose of each method will be recorded. After completion of these three examinations, the participation in the study is completed.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Patients scheduled for lung imaging
Patients with lung changes and scheduled for lung imaging will undergo:
* the scheduled conventional X-ray examination
* the scheduled CT scan
* the tomosynthesis scan
Tomosythesis scan of the lung or the wrist
All study participants will undergo Tomosynthesis imaging of the lung or the wrist. The radiation dose of each method will be recorded.
CT scan of the lung or the wrist
All study participants will undergo CT imaging of the lung or the wrist, for which they where originally scheduled. The radiation dose of each method will be recorded.
conventional X-ray of the lung or the wrist
All study participants will undergo conventional X-ray of the lung or the wrist, for which they where originally scheduled. The radiation dose of each method will be recorded.
Patients scheduled for wrist imaging
Patients with wrist fracture or with osteoprotetic material in the wrist and scheduled for wrist imaging will undergo:
* the scheduled conventional X-ray examination
* the scheduled CT scan
* the tomosynthesis scan
