Abstract

An electron beam therapy system and a facility for using an electron beam therapy system. In the preferred embodiment, the electron beam therapy system comprises a linear accelerator, microwave source, and associated electronics disposed in a housing. The housing is mounted on a positioning means such as a C-arm to direct the electron beam to the desired site on the patient. The entire housing and positioning means is mobile and may be moved to different locations in the facility. Connectors are provided at the different locations in the facility to connect the electron beam source to a central power source within the facility.

Claims

1. A mobile electron beam therapy system comprising:

a housing;

an electron beam source disposed within said housing for generating an electron beam using an s-band linear accelerator;

said electron beam source and said linear accelerator being interpositioned so that a generated electron beam exits said linear accelerator collinearly in the direction electrons travel within said accelerator;

applicator means associated with the housing for directing an electron beam generated by the electron beam source; and

means for positioning the housing so that the applicator means directs an electron beam generated by the electron beam source in a continuous path in line with said linear beam to a predetermined location in patient treatment.

2. The mobile electron beam therapy system of claim 1 wherein the electron beam source further comprises a microwave source disposed within the housing.

3. The mobile electron beam therapy system of claim 2 wherein the electron beam source further includes a pulse transformer disposed within the housing.

4. The mobile electron beam therapy system of claim 1 wherein the means for positioning comprises means for rotating the housing about a first axis.

5. The mobile electron beam therapy system of claim 4 wherein the means for positioning further comprises means for rotating the housing about a second axis.

6. The mobile electron beam therapy system of claim 5 wherein the means for positioning further comprises means for moving the housing vertically with respect to the patient.

7. The mobile electron beam therapy system of claim 6 wherein the means for positioning comprises a C-arm.

8. The mobile electron beam therapy system of claim 7 further comprising a beam stopper mounted on the C-arm.

9. The mobile electron beam therapy system of claim 1 wherein the means for moving comprises a wheeled mount.

10. The mobile electron beam therapy system of claim 1 further comprising a power source and means for connecting the power source to the electron beam source.

11. The mobile electron beam therapy system of claim 10 wherein the means for connecting comprises a first connector at the first location and a second connector at the second location.

12. An electron beam therapy system comprising:

a plurality of locations adapted for treating patients with electron beam therapy;

a mobile electron beam therapy system as described in claim 1;

means for moving the electron beam source into any of said plurality of locations; and

means in each room for connecting the electron beam source to a utility source.

13. The electron beam therapy facility of claim 12 wherein the electron beam therapy system comprises a housing and an electron beam source disposed within the housing and wherein said means within each room as a supply for said electron beam source also comprises a cooling system.

14. The electron beam therapy facility of claim 12 further comprising applicator means on the housing for directing an electron beam generated by the electron beam source and means for positioning the housing so that the applicator means directs an electron beam generated by the electron beam source to a predetermined site on a patient.

15. Apparatus in accordance with claim 1 including means to permit easy movement of the housing and the means for positioning together from a first location to a second location.
