Importance of Attenuation Correction (AC) for Small Animal PET Imaging.
UNLABELLED The purpose of this study was to investigate whether a correction for annihilation photon attenuation in small objects such as mice is necessary. The attenuation recovery for specific organs and subcutaneous tumors was investigated. A comparison between different attenuation correction methods was performed. METHODS Ten NMRI nude mice with subcutaneous implantation of human breast ...
متن کاملAttenuation correction for small animal PET tomographs.
Attenuation correction is one of the important corrections required for quantitative positron emission tomography (PET). This work will compare the quantitative accuracy of attenuation correction using a simple global scale factor with traditional transmission-based methods acquired either with a small animal PET or a small animal x-ray computed tomography (CT) scanner. Two phantoms (one mouse-...
متن کاملAtlas-based attenuation correction for small animal PET/MRI scanners
Small animal PET/MRI scanners producing anatomically co-registered simultaneously-acquired images of morphology, function and metabolic activity have become available and are expected to have a huge positive impact on the pre-clinical imaging field. Attenuation correction (AC) necessary for accurate quantification of PET signals is challenging in these scanners because the measured anatomical m...

متن کاملDevelopment of pre-processing methods for attenuation correction algorithms in small animal PET/MR imaging
Signal processing includes a wide variety of signals, such as 2D and 3D images. New techniques of signal processing are widely accepted in medicine, where inter-modality techniques are today unquestionably required for its use in diagnosis. Tumor or Alzheimer detection requires the use of new radio-pharmaceutical tracers that should be tested in small animals, such as mice or rats. Medical tech...
