Abstract
A system and method are provided for the reconstruction of medical image data using filtered backprojection with the use of a wavelet transformation. A filter function is applied to at least one part of an object using projection data captured with a detection device prior to backprojection.
Claims17
A method for a reconstruction of medical image data using filtered backprojection, the method comprising:
- identifying projection data of an object;
- and
- applying, by a processor, with a wavelet transformation, a filter function to at least one part of the object, wherein the filter function is applied in a wavelet space.
An apparatus for reconstruction of medical image data using filtered backprojection, the apparatus comprising:
- a detection device configured to acquire projection data of an object;
- a memory configured to store the projection data;
- and
- a processor configured to apply, with a wavelet transformation, a filter function to at least one part of the object, wherein the filter function is applied in a wavelet space.
