Description:[001] The present invention relates to the field of medical science, and more particularly, the present invention relates to the external body fiducial marker belt.
BACKGROUND FOR THE INVENTION:
[002] The following discussion of the background to the invention is intended to facilitate an understanding of the present invention. However, it should be appreciated that the discussion is not an acknowledgment or admission that any of the material referred to was published, known, or part of the common general knowledge in any jurisdiction as of the priority date of the application. The details provided herein the background if belongs to any publication is taken only as a reference for describing the problems, in general terminologies or principles or both of science and technology in the associated prior art.
[003] The patient lie down on the couch of the Simulator for CT scan, required for the treatment planning and treatment delivery in the Linear Accelerator machine. The LASERs are present in the CT Simulator and Linear Accelerator Room for patient positioning. The immobilization device like cast and cushions are prepared for individual patient and while it is used on patient, LASERs are utilized to position the patient accurately. There are three marking points on the cast/ cushion where small lead balls are affixed for generating a reference point which helps in shifting machine iso-center to the tumor center for treatment. It has been observed that these three small lead balls are not appear in single CT slice which create errors in giving the reference point for patient treatment.
[004] In light of the foregoing, there is a need for the External body fiducial marker belt that overcomes problems prevalent in the prior art. The belt can be designed which will have three small lead balls with scale and fixing mechanism with patient base plate. This belt will remove the error of lead ball fixing on the cast/ cushion for a patient. The single belt can be utilized in any patient which is to be plan for external beam radiotherapy treatment.
OBJECTS OF THE INVENTION:
[005] Some of the objects of the present disclosure, which at least one embodiment herein satisfies, are as follows.
[006] The principal object of the present invention is to overcome the disadvantages of the prior art by providing the External body fiducial marker belt.
[007] An object of the present invention is to provide the external body fiducial marker belt that can be fit on the cast and cushion in the patient.
[008] Another object of the present invention is to provide the external body fiducial marker belt that is having small lead balls with scale to properly mark the LASERs position.
[009] Another object of the present invention is to provide the external body fiducial marker belt that is cost-effective and easy to place in the patient.
[010] Another object of the present invention is to provide the external body fiducial marker belt that is very helpful in the cancer patient treatment with accurate position.
[011] Other objects and advantages of the present disclosure will be more apparent from the following description, which is not intended to limit the scope of the present disclosure.
SUMMARY OF THE INVENTION:
[012] The present invention provides an external body fiducial marker belt.
[013] In one aspect of the present invention, the marked belt includes a base plate; and a belt with three fiducial makers having lead scale markings thereon.
[014] In another aspect of the present invention, the belt’s end is fixed in the base plate.
[015] In another aspect of the present invention, the belt is made with a minimum radiation absorption material.
[016] In another aspect of the present invention, the belt is flexible to take the shape of the patient body contour.
[017] In another aspect of the present invention, the small lead balls are affixed over the patient immobilization device manually.
BRIEF DESCRIPTION OF DRAWINGS:
[018] Reference will be made to embodiments of the invention, examples of which may be illustrated in accompanying figures. These figures are intended to be illustrative, not limiting. Although the invention is generally described in the context of these embodiments, it should be understood that it is not intended to limit the scope of the invention to these particular embodiments.

DETAILED DESCRIPTION OF DRAWINGS:
[020] While the present invention is described herein by way of example using embodiments and illustrative drawings, those skilled in the art will recognize that the invention is not limited to the embodiments of drawing or drawings described and are not intended to represent the scale of the various components. Further, some components that may form a part of the invention may not be illustrated in certain figures, for ease of illustration, and such omissions do not limit the embodiments outlined in any way. It should be understood that the drawings and the detailed description thereto are not intended to limit the invention to the particular form disclosed, but on the contrary, the invention is to cover all modifications, equivalents, and alternatives falling within the scope of the present invention as defined by the appended claim.
[021] As used throughout this description, the word "may" is used in a permissive sense (i.e. meaning having the potential to), rather than the mandatory sense, (i.e. meaning must). Further, the words "a" or "an" mean "at least one” and the word “plurality” means “one or more” unless otherwise mentioned. Furthermore, the terminology and phraseology used herein are solely used for descriptive purposes and should not be construed as limiting in scope. Language such as "including," "comprising," "having," "containing," or "involving," and variations thereof, is intended to be broad and encompass the subject matter listed thereafter, equivalents, and additional subject matter not recited, and is not intended to exclude other additives, components, integers, or steps. Likewise, the term "comprising" is considered synonymous with the terms "including" or "containing" for applicable legal purposes. Any discussion of documents, acts, materials, devices, articles, and the like are included in the specification solely for the purpose of providing a context for the present invention. It is not suggested or represented that any or all these matters form part of the prior art base or were common general knowledge in the field relevant to the present invention.
[022] In this disclosure, whenever a composition or an element or a group of elements is preceded with the transitional phrase “comprising”, it is understood that we also contemplate the same composition, element, or group of elements with transitional phrases “consisting of”, “consisting”, “selected from the group of consisting of, “including”, or “is” preceding the recitation of the composition, element or group of elements and vice versa.
[023] The present invention is described hereinafter by various embodiments with reference to the accompanying drawing, wherein reference numerals used in the accompanying drawing correspond to the like elements throughout the description. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiment set forth herein.
