Abstract

Provided is a treating apparatus including an ion generating apparatus configured to inject ionized elements into a diagnosis subject to remove a tumor in the diagnosis subject, and an image photographing apparatus configured to measure positions of the ionized elements in the diagnosis subject. The ion generating apparatus includes a target including a first element and a first isotope that is a radioactive isotope of the first element, and a laser configured to allow a laser beam to be incident on the target and thus ionize the first element and the first isotope.

First claim

What is claimed is:

1. A treating apparatus comprising:
an ion generating apparatus configured to inject ionized elements into a diagnosis subject to remove a tumor in the diagnosis subject; and
an image photographing apparatus configured to measure positions of the ionized elements in the diagnosis subject,
wherein the ion generating apparatus includes:
a target including a first element and a first isotope that is a radioactive isotope of the first element; and
a laser configured to allow a laser beam to be incident on the target and thus ionize the first element and the first isotope.

2. The treating apparatus of claim 1 , wherein the positions are positions at which the ionized elements form Bragg peaks.

3. The treating apparatus of claim 2 , wherein the image photographing apparatus measures a position of an ionized first isotope among the ionized elements.

4. The treating apparatus of claim 3 , wherein the image photographing apparatus includes positron emission tomography (PET) equipment.

5. The treating apparatus of claim 1 , wherein the target includes about 99.9% to 99.99% of the first element and 0.01% to 0.1% of the first isotope.

6. The treating apparatus of claim 1 , wherein number of electrons of the ionized first element is the same as the number of the electrons of the ionized first isotope.

7. The treating apparatus of claim 1 , wherein the target includes
a first portion; and
a second portion,
wherein the first portion includes the first element and the first isotope, and the second portion includes a second element that is different from the first element and a second isotope that is the radioactive isotope of the second element.

8. The treating apparatus of claim 1 , wherein the target includes
a first portion; and
a second portion,
wherein the first portion includes the first element and the first isotope at a first ratio, and the second portion includes the first element and the first isotope at a second ratio that is different from the first ratio.

9. The treating apparatus of claim 1 , wherein the first element includes any one of carbon, fluorine, nitrogen, or oxygen.

10. A treating method comprising:
preparing a target including a first element and a first isotope that is a radioactive isotope of the first element;
allowing a laser beam to be incident on the target to ionize the first element and the first isotope;
allowing the ionized first element to be incident into a diagnosis subject to remove a tumor in the diagnosis subject;
allowing the ionized first isotope to be incident into the diagnosis subject; and
confirming positions at which the ionized elements in the diagnosis subject form Bragg peaks.

11. The treating method of claim 10 , wherein the confirming of the positions of the ionized elements includes:
confirming a position of the ionized first isotope in the diagnosis subject; and
confirming a position of the ionized first element by using the position of the ionized first isotope.

12. The treating method of claim 11 , wherein the confirming of the position of the ionized first isotope includes detecting an annihilation radiation emitted from the ionized first isotope to confirm the position.

13. The treating method of claim 12 , wherein the detecting of the annihilation radiation includes confirming using positron emission tomography (PET) equipment.

14. The treating method of claim 10 , wherein the allowing of the ionized first element to be incident into the diagnosis subject and the allowing of the ionized first isotope to be incident into the diagnosis subject are simultaneously performed.

15. The treating method of claim 10 , wherein the allowing of the ionized first element and the ionized first isotope to be incident into the diagnosis subject, and the confirming of the position of the ionized first element are simultaneously performed.

16. The treating method of claim 10 , wherein the allowing of the ionized first element and the ionized first isotope to be incident into the diagnosis subject is performed before the confirming of the position of the ionized first element.

17. The treating method of claim 10 , wherein number of electrons of the ionized first element is the same as the number of the electrons of the ionized first isotope.

18. The treating method of claim 10 , wherein the first element includes any one of carbon, fluorine, nitrogen, or oxygen.

19. An ion generating apparatus comprising:
a target; and
a laser configured to allow a laser beam to be incident on the target and thus generate ionized elements from the target,
wherein the target includes:
a first element; and
a first isotope that is a radioactive isotope of the first element.

20. The ion generating apparatus of claim 19 , wherein the target includes 99.9% to 99.99% of the first element and about 0.01% to 0.1% of the first isotope.

21. The ion generating apparatus of claim 19 , wherein the first element includes any one of carbon, fluorine, nitrogen, or oxygen.

22. The ion generating apparatus of claim 19 , wherein the target includes
a first portion; and
a second portion,
wherein the first portion includes the first element and the first isotope, and the second portion includes a second element that is different from the first element and a second isotope that is the radioactive isotope of the second element.

23. The ion generating apparatus of claim 19 , wherein the target includes
a first portion; and
a second portion,
wherein the first portion includes the first element and the first isotope at a first ratio, and the second portion includes the first element and the first isotope at a second ratio that is different from the first ratio.
