Review paper for visual-Ct gel-dosimetry - Article ExampleThis advanced constitution incorporates the map of both Optical information processing system Tomography (CT) Scanning and Gel- Dosimetry which as shall be shown do deliver demigod maps with high degrees of gag law, precision and accuracy. 2. Introduction One of the key elements in the world is the conniption of radiation treatment. This has come in handy in the fight against some of the worlds deadliest ailments which the scientific world has always grappled with to fix. A major part of radiation treatment is radiation dosimetry which has had an increased postulate for a system that has a high degree of accuracy, precision and efficiency in the measuring of dose and in full 3D and high resolution (INTERNATIONAL CONFERENCE ON 3D RADIATION DOSIMETRY, & OLDHAM, M 2010). A lot of work has gone into the traditional systems like the Fricke dosimetry and this has had a tremendous result which is manifested by the effectiven ess of Gel-dosimetry. A further development has seen the incorporation of Optical Computer Tomography (CT) Scanning into the system of Gel-dosimetry and this complementary system has been observed to have a high degree of accuracy, precision and efficiency. The main accusative of this paper is to manifest the authenticity of this statement. In an effort to prove the effectiveness of the newly developed system, an experimental frame-up was put in place which has delivered results that have received thumbs up from the scientific world. The setup makes use of some 2-dimensional images from defined planes in a gel-dosimeter that is well constructed from a perfect design. Moreover, the performance of Optical Computer Tomography (CT) Scanning is compared with that of a MR scanning with focus being on accuracy and sensitivity of imaging, calibration, resolution and noise in the images of dosimetry. Work has been done to eliminate the sources of geometric distortion and optical artifact s in optical Computer Tomography Scanning. The new design has mechanisms to compensate for refraction, reflection, signal drift, water supply-bath imperfections amongst other factors that cause incorrect reconstructions of coefficients of infinite attenuation. It is also the objective of this paper to show that indeed for phantoms which are used in the validation of optical CT scanners used together with the polymerizing gel dosimeters that are radiation induced, stable gel materials are needed. Phantoms on which light dyes are added are the basis of the simulation used as gel dosimeters. More accurate simulations are done with the use of phantoms with light scattering suspensions of colloidal mixed with the gal. 3. Body An experimental setup to prove the effectiveness of the newly developed system involved filling up three resembling flasks with 300cc MGS Research BANG3 gel. The flasks had their heads stopped with a threaded screw allowing vertical mounting of the flask into th e desired optical scanner as well as head phantom. One of the flasks was used in the study of a complex radio surgical delivery as a dosimeter while the other two were used to examine calibration issues of gel. The two gel-flasks of calibration were put in a birth of water upright and 6MV beams of radiosurgery used to irradiate them shooting through their flat bases vertically upward. The beams gave doses of 1.5, 0.75, and 0.25 Gy into the first flask and in the second one 1.25, 1.0 and 0.5 Gy. Before the end of 48 hours, these flasks were scanned using both imaging modalities. Data on calibration was gotten by taking the
