Focusing on the measurement function loaded on our rigid-typed endoscope for the fetal surgery treatment, we proposed that its combination with a generally used digestive endoscope enabled calibration of lesion size in stomach. While adding the function, with which the target size is to be easily measured, on the endoscope, we simplified the system structure as much as possible. We also tried to minimize the total cost by using the generally used endoscope, instead of making it from scratch. Combining another development, the composite-type optical fiberscope with diameter of 1.1mm, with a generally used endoscope, we proposed the following as the features: (1)acquisition of fiberscope image, (2)laser irradiation for treatments, (3)applying the real time measurement function of distance and blood flow by semiconductor laser to the generally used endoscope. We have operated the clinical study to the gastric wall of person with no health problem, using this system and confirmed it was available for practical use.

For heavy-ion cancer therapy with carbon, there is a problem about radiation exposure due to secondary particles produced by heavy ion incident reaction. We have a plan to extend our improved intra nuclear cascade (INC) model for proton incidences to INC model for alpha and carbon incidences. However, there is no experimental data about multi-particle (proton, deuteron, triton, 
He and alpha) production double differential cross sections (DDXs) for alpha incident reactions to validate the extended INC model. In this work, we measured multi-particle production DDXs for 100 and 230 MeV/nucleon alpha incident reactions on samples (C, Al, Co, Nb) at the HIMAC building in National Institute of Radiological Sciences (NIRS), QST. As a result, we found that results calculated by the extended INC model agreed with experimental data at 30 degrees and those underestimated the experimental data with increasing angles.
