| Summary: | Phantom studies are an important part in medical imaging as it can evaluate the
performance and quality assurance (QA) test of dual-modality PET/CT. The purpose of
this study is to, design, fabricate and develop a multipurpose smart phantom which
includes the internal structures, water, human tissue equivalent materials and radioactive
source for dual-modality Positron Emission Tomography/Computed Tomography
(PET/CT) imaging. In this study, experimental determination of Hounsfield units (HU),
mass attenuation coefficient, elemental composition analysis and structure analysis were
performed on phantom materials using PET/CT scanner, Multichannel Analyser (MCA),
CI-INS analyser and Scanning Electron MicroscopelEnergy Dispersive X-Ray
(SEMlEDX) respectively.
Kajian fantom adalah bahagian yang penting dalam pengimejan perubatan kerana ia
dapat menilai pedaksanaan dan ujian jaminan kualiti (QA) dwi-modaliti Tomografi
Pancaran Positronffomografi Berkomputer {PETtCT). Tujuan kajian ini adalah untuk
merekabentuk, memfabrikasi dan membangunkan fantom pintar pelbagai tujuan yang
termasuk struktur dalaman, air, bahan-bahan setara dengan tisu manusia dan sumber
radioaktif untuk pengimejan dwi-modaliti PETtCT. Dalam kajian ini, penentuan secara
eksperimen Unit Hounsfield (HU), pekali atenuasi jisim, analisis komposisi elemen dan
analisis struktur telah dilakukan terhadap bahan-bahan fantom menggunakan PETtCT
skan, Penganalisis Berbilang Saluran (MCA), Penganalis CHNS dan Pengimbas
-Mikroskop ElektronIKeselerakan Tenaga X-ray (SEMlEDX) masing-masing. |
