Med. Biol.誌に採録されたことを受けて、文部科学省で記者会見を行いました。その結果、２月８日の首都圏のニュース（おはよう日本７：３０台）で放映された他、朝日新聞や日本経済新聞にも掲載されました。癌診断・治療に対する関心の高さが伺われます。ただし、一部の報道では「Open PET」の装置が完成したように表現されていますが、これは間違いです。[プレス発表] 以前のニュース（previous news）

Figure 2. jPET-D4 preliminar images of a healthy volunteer brain (22-years old male) reconstructed using a 3D-OSEM with the DOI compression method including some programing bugs.
The spatial resolution is expected to be less than 3 mm anywhere in early 2007.
