X-ray device and medical workplace for diagnostics and surgical interventions in the head and/or jaw of a patient

Claim 2

An X-ray device for obtaining radiological exposures of the head and jaw region of a patient, comprising: an X-ray source which emits a conical X-ray bundle, having a central beam; a radiation detector disposed relative to said X-ray source so that said central beam strikes said detector approximately centrally; a supporting arrangement for said X-ray source and said radiation detector, said supporting arrangement comprises a first support stand on which said X-ray source is mounted and a second support stand on which said radiation detector is mounted; a motorized drive for rotating said supporting arrangement around an axis for picking up a series of 2D projections of a patient region selected from the group consisting of the head region and the jaw region; and a computer supplied with said 2D projections for generating a 3D image dataset therefrom.

Claim 3

An X-ray device as claimed in claim 1 wherein said motorized drive includes at least one digitally controlled drive.

Claim 4

An X-ray device as claimed in claim 2 wherein said digitally controlled drive is a stepper motor.

Claim 5

An X-ray device as claimed in claim 1 wherein said radiation detector is mounted for adjustment along a direction of said central beam.

Claim 6

A medical workplace for diagnostics and surgical interventions in a head or jaw region of a patient, comprising: an x-ray source which emits a conical X-ray bundle having a central beam; a radiation detector disposed relative to said X-ray source so that said central beam strikes said detector approximately centrally; a patient support adapted to receive a patient to orient the patient's head between said X-ray source and said radiation detector; a supporting arrangement for supporting said X-ray source and said radiation detector; a motorized drive for rotating said supporting arrangement around an axis to obtain a series of 2D projections of the head region of the patient; a position identifying arrangement for obtaining position information, at least while said series of 2D projections are obtained, identifying respective positions of said X-ray source, said radiation detector and said patient support; and a computer supplied with said series of 2D projections and said position information for generating a 3D image dataset from said series of 2D projections and said position information.

Claim 7

A medical workplace for diagnostics and surgical interventions in a head or jaw region of a patient, comprising: an x-ray source which emits a conical X-ray bundle having a central beam; a radiation detector disposed relative to said X-ray source so that said central beam strikes said detector approximately centrally; a patient support adapted to receive a patient to orient the patient's head between said X-ray source and said radiation detector; a supporting arrangement for supporting said X-ray source and said radiation detector; a motorized drive for rotating said supporting arrangement around an axis to obtain a series of 2D projections of the head region of the patient; a position identifying arrangement for obtaining position information, at least while said series of 2D projections are obtained, identifying respective positions of said X-ray source, said radiation detector and said patient support; and a computer supplied with said series of 2D projections and said position information for generating a 3D image dataset from said series of 2D projections and said position information.

Claim 8

A medical workplace as claimed in claim 5 wherein said position identification arrangement is a navigation system.

Claim 9

A medical workplace as claimed in claim 5 further comprising an instrument adapted for use in a surgical intervention at the head of the patient, and wherein said position identification system also identifies a position of said instrument, and further comprising a display connected to said computer at which an image produced from said 3D image dataset is displayed, showing a position of said instrument within said image.
