PVA cryogel test objects for image-based quantification in nuclear medicine

The images shown prove the feasibility of our method for the production of an anatomically relevant phantom that can be used to represent a 177Lu-DOTATATE or other radiopharmaceutical distribution in patients for the purpose of investigating image quantification for applications such as dosimetry or functional volume segmentation. The images produced are similar in appearance to those acquired for real patients. The use of a range of sphere diameters mimics the range of lesion sizes that take up activity in tumours.
