Method and apparatus for improving image quality in positron emission tomography |
摘要 |
A method and apparatus for improving the image quality of positron emission tomography is disclosed. This is achieved by analysing individual photomultiplier tubes for true events. The apparatus includes a photomultiplier tube for generating a photomultiplier tube signal. A series of pull up resistors generates a code signal identifying the photomultiplier tube. A clock generates a time stamp to the photomultiplier tube signal. A bus buffer generates an encoded signal. A position computing device calculates the position of the photomultiplier tube. An image computer generates an image from a plurality of encoded signals. A display displays the image. Analysing data from individual photomultiplier tubes results in smaller areas and smaller amounts of data to be processed. This then permits smaller time franm windows to be used. The use of time stamps also permits data before and after an event to be recorded.
