Dalam mendapatkan hasil pencitraan Kedokteran Nuklir yang baik adalah didukung dengan instrumen dengan performa yang baik yaitu sesuai dengan standar mutu alat tersebut. Untuk menjaga agar performa instrumen tetap bekerja secara optimal harus dilakukan uji secara berkala dengan protokol uji yang tepat. Penelitian ini dilakukan untuk menguji kualitas citra kamera gamma dengan fantom IEC 61675-2 dan membuat protokol pengujianya meliputi pengujian resolusi radial, resolusi tangensial dan scatter fraction. Pengujian resolusi radial dan resolusi tangensial dilakukan menggunakan sumber titik sedangkan untuk pengujian scatter fraction menggunakan sumber garis. Dari penelitian ini didapatkan hasil rerata FWHM untuk resolusi radial 14,08, pada resolusi tangensial 10,21 mm. Untuk pengujian scatter fraction didapatkan hasil 0,042 dengan prosentase hamburan 4,2%.
In order to achieve an optimal scanned image of nuclear medicine device, a good instrument with proper performance which is consistent with its standard quality is required. Furthermore, suitable and periodic protocol test is also a good requirement so that the instrument can extend its maximum performance.In order to Achieve an optimal scanned image of nuclear medicine devices, a good instrument with proper roomates performance is consistent with its standard quality is required. This research was conducted to test the image quality of gamma cameras with phantom IEC 61675-2 and make protocol includes testing radial resolution, tangential resolution and scatter fraction. Test of tangential and radial resolution made using a point source, while for test Scatter fraction using a line source. From this research, the results of the mean FWHM for the radial resolution 14.08 mm and 10.21 mm in tangential resolution. test Scatter fraction obtained scattering percentage of 4.2%.

This classic text has been used in over 20 countries by advanced undergraduate and beginning graduate students in biophysics, physiology, medical physics, neuroscience, and biomedical engineering. It bridges the gap between an introductory physics course and the application of physics to the life and biomedical sciences. Extensively revised and updated, the fifth edition incorporates new developments at the interface between physics and biomedicine. New coverage includes cyclotrons, photodynamic therapy, color vision, x-ray crystallography, the electron microscope, cochlear implants, deep brain stimulation, nanomedicine, and other topics highlighted in the National Research Council report BIO2010. As with the previous edition, the first half of the text is primarily biological physics, emphasizing the use of ideas from physics to understand biology and physiology, and the second half is primarily medical physics, describing the use of physics in medicine for diagnosis (mainly imaging) and therapy. Among the many topics carried forward are thorough treatments of forces in the skeletal system, fluid flow, the logistic equation, scaling, equilibrium in statistical mechanics, the chemical potential and free energy, transport, membranes and osmosis, magnetic and electrical signals from nerves and the heart, membranes and gated channels in membranes, biological magnetic fields, linear and nonlinear feedback systems, including biological clocks and chaotic behavior, biological signal analysis, hearing and medical ultrasound, atoms and light, optical coherence tomography, radiometry and photometry, the interaction of photons and charged particles in tissue, radiological physics and the use of x-rays in diagnosis and therapy, nuclear medicine, and magnetic resonance imaging. Discussion of theory is closely linked to experiment. Prior courses in physics and in calculus are assumed.

Abstrak :
This book explains the anatomy and physiology of cartilage tissue in an integrated way. The emphasis is on how cartilage tissue functions and maintains homeostasis in a challenging mechanical environment. Supported by hundreds of references, the book posts new hypotheses explaining how cartilage adapts and achieves homeostasis in vivo, and tests them against available data. This exploratory approach creates a sense of discovery that the reader can join, or perhaps test themselves through their own research. The main benefit will be obtained by research students and professors looking to understand the deeper concepts that will further their own research, or clinicians (including health professionals and surgeons) who want to gain a deeper physiological understanding of cartilage tissue, which can then serve as a basis for more rational clinical decision-making they need to make on a daily basis. To help bridge the gap between basic science and clinically relevant joint disease, applications and interpretations of key physiological concepts are discussed in the context of osteoarthritis at the end of most chapters.
