Method and Device for the Spectrophotometric Determination of Residual Phase Transfer Catalyst in a PET Radiopharmaceutical Dose
The Problem:Phase transfer catalyst, such as Kryptofix-222 or 18-Crown-6, have to be used to manufacture fluorine-18 labeled radiotracers. Although the purification process of the radiotracer is designed to remove any impurities in the final dose, residual phase transfer catalyst remains present. TLC plates are currently the method to control for the... (read more) -
Novel Method for Head & Neck and Respiratory Motion Correction in Positron Emission Tomography (PET)
The Problem: As the use of PET imaging continues to increase, it is imperative to address the current, inadequate means for motion correction. During PET imaging, a summation image is generated while the patient is instructed to lie still on his/her back for the duration of the scan. A typical PET scan lasts 15 to 30 minutes on average Patient motion... (read more)
