Abstract

The study presented a rare case of inflammatory myofibroblastic tumor (IMT) in a 57-year old male patient who presented with recurrent abdominal pain. He was diagnosed to have a tumor of the small intestine within ileal intussusception, demonstrated by CT enterography. The patient underwent surgery to remove the tumor with a margin of healthy tissue. Histopathological and immunohistochemical examination results enabled to diagnose IMT. IMT is a rare tumor that occurs mainly in children and young adults. Its etiology remains to be fully understood. Due to the differentiated histology it can be found in many organs and soft tissues, being responsible for different, non-specific clinical and radiological symptoms. Due to the rarity of this tumor a clear treatment protocol has not yet been established. However, given the tendency to recur with possible distant metastases an important element of treatment consists in long-term clinical patient observation.

Abstract

The Jagiellonian Positron Emission Tomograph (J-PET) collaboration is developing a prototype time of flight (TOF)-positron emission tomograph (PET) detector based on long polymer scintillators. This novel approach exploits the excellent time properties of the plastic scintillators, which permit very precise time measurements. The very fast field programmable gate array (FPGA)-based front-end electronics and the data acquisition system, as well as low- and high-level reconstruction algorithms were specially developed to be used with the J-PET scanner. The TOF-PET data processing and reconstruction are time and resource demanding operations, especially in the case of a large acceptance detector that works in triggerless data acquisition mode. In this article, we discuss the parallel computing methods applied to optimize the data processing for the J-PET detector. We begin with general concepts of parallel computing and then we discuss several applications of those techniques in the J-PET data processing.
