The wire mesh collimator gamma camera possesses the ability to transform the current gamma camera or Single Photon Emission Computed Tomography (SPECT) camera into a highly sensitive imaging device to detect breast cancer cells at its earliest stage and are as small as 1mm for certain cases. The researcher focusses on both the hardware and software aspects of medical imaging devices. Gamma cameras are effective in detecting cancerous cells in human bodies because cancerous cells are hyperactive in nature However, due to the high energy of gamma rays emitted from radionuclides (such as Tc-99m that emits 140eV), the capacity of detecting hyper-active cells is usually limited by its poor resolution.
Currently in Malaysia, most of the medical imaging devices, either Computer Tomography, MRI, Gamma Camera, Ultrasound, PET, SPECT etc. are all imported from overseas. Most of the time, the usage of the machines is limited by either the competency of the operator or the limited technical capability of the machine (hospitals do not have financial budget to buy the most sophisticated machines).
Gamma camera/SPECT is an ionizing medical imaging technique that uses radioactive radionuclides to detect the active organs in human’s body. Fundamentally, a gamma camera will be very useful to detect cancerous cells in human’s body because cancerous cells are hyper-active cells. However, due to the high energy of gamma rays emitted from radionuclides (such as Tc-99m that emits 140keV), the capability of detecting hyper-active cells are usually been limited by its poor resolution. Due to this reason, although hospitals in Malaysia have many gamma camera/SPECT machines, the machines cannot be used up to their full potential. This medical innovation will help the running of the machine at a cheaper cost, help to detect cancer at the earlier stage and help to fully utilize the gamma camera/SPECT machines in the country – the real meaning of medical innovation.
This patented product will transform the current gamma camera or SPECT camera to become a highly sensitive imaging device to detect breast cancer at the earlier stage. Collimator is one part of a gamma camera that is very important as a “lens” before the gamma rays The wire mesh collimator will be able to be used with all current gamma cameras/SPECT cameras in the country, thus save the money to buy a new sophisticated machine.
