Abstract
An apparatus including a first radiation source attached to a first gantry, at least one second radiation source, a second gantry that is rotatable; and an imager attached to an articulable end of the second gantry.
Claims26
An apparatus comprising:
- a first therapeutic radiation source attached to a first gantry;
- at least one second radiation source;
- a second gantry that is rotatable, the second gantry is attached to the first gantry;
- and
- an imager attached to an articulable end of the second gantry.
2 more elements
An apparatus comprising:
- a first radiation source attached to a first gantry;
- at least one second radiation source, wherein the at least one second radiation source is attached to the first gantry;
- a second gantry that is rotatable;
- and
- an imager attached to an articulable end of the second gantry.
2 more elements
An apparatus comprising:
- a first radiation source attached to a first gantry;
- at least one second radiation source;
- a second gantry that is rotatable, wherein the second gantry is capable of extending and retracting the second radiation source attached to the second gantry;
- and
- an imager attached to an articulable end of the second gantry.
2 more elements
A method for applying radiation, comprising:
- positioning a diagnostic X-ray source to be in alignment with a target volume;
- positioning an imager at one of a plurality of distances from the target volume to receive radiation from the diagnostic X-ray source;
- positioning a therapeutic radiation source to be in alignment with the target volume;
- and
- re-positioning the imager to receive radiation from the therapeutic radiation source.
2 more elements
A method for imaging radiation, comprising:
- positioning a multiple-energy imaging unit normal to a first axis to receive radiation at a first energy level;
- propagating radiation by a first radiation source at the first energy level along the first axis;
- retracting the first radiation source and positioning a second radiation source along the first axis;
- maintaining the multiple-energy imaging unit normal to the first axis to receive radiation by the second radiation source;
- and
- propagating radiation by the second radiation source.
3 more elements
An apparatus, comprising:
- a therapeutic energy source attached to a first gantry;
- a diagnostic X-ray energy source attached to a retractable end of a second gantry;
- a multiple-energy imaging unit attached to an opposite articulable end of the second gantry;
- the first gantry and the second gantry independently pivotable and attached at a common axis;
- a patient couch capable of translation, wherein the result of such pivoting and translation is to place a target volume of a patient between the multiple-energy imaging unit aligned with the diagnostic energy source or the therapeutic energy source.
