Mr Erik Vallazza (INFN Triest)24/02/2007, 09:00Contributed TalkDuring 2006 the SYRMEP (Synchrotron Radiation for Medical Physics) collaboration performed worldwide unique clinical mammographic examinations using X-rays generated by one of the bending magnets at the synchrotron radiation facility Elettra (Trieste, Italy). While these examinations have been performed with traditional screen-film systems, recently a major effort has been pursued in...Go to contribution page

Sara Vecchio (INFN Pisa)24/02/2007, 09:25Contributed TalkWe have developed a tomograph for single photon emission imaging (SPECT) of the breast for the detection of small size tumors. The patient is prone with a pendulus breast. The SPECT is mounted on a ring that is rotating around the breast. The breast will be imaged by two opposing detector heads of approximately 5x15 cm^2 each, with a field of view about 13 cm wide. Each head is made up of...Go to contribution page

Giacomo Bartesaghi (INFN Mailand)24/02/2007, 09:50Contributed TalkRadiotherapy, together with chemiotherapy and surgery, is one of the main methods applied in the fight against cancer; in order to increase the chances of a successful radiotherapy treatment the dose delivery to the tumour areas and the surrounding normal tissues has to be computed with high accuracy. Standard dosimeters are accurate but too small (ionization chambers and diodes) or...Go to contribution page

Valentina Conti (INFN Mailand)24/02/2007, 10:15Contributed TalkBoron Neutron Capture Therapy (BNCT) is a therapeutic technique exploiting the release of dose inside the tumour cell after a fission of a 10B nucleus following the capture of a thermal neutron. BNCT could be the treatment for extended tumours (liver, stomach, lung), radio-resistant ones (melanoma) or tumours surrounded by vital organs (brain). The application of BNCT requires a high...Go to contribution page

Mr Andrew Blue (Uni Glasgow)24/02/2007, 11:10Contributed TalkA monolithic active pixel sensor, Vanilla, with 512x512 pixels (25μm square) has been fully characterised for the first time. Using PTC (Photon Transfer Curve) measurements allowed for the calculation of the read noise, shot noise, full well capacity and camera gain constant. Spectral response measurements detailed the QE of the detector through the UV and visible region....Go to contribution page

Tsutomu Nagayoshi (Waseda University, Tokyo)24/02/2007, 11:35Contributed TalkAstronauts have to receive the risk of radiation exposure in space. The radiation dose rate is about a hundred times as much as that on the ground. Hence, precise radiation dosimetry in space is necessary to control the health of astronauts. We started to develop a new dosimeter named “Position Sensitive Tissue Equivalent Proportional Counter (PS-TEPC)” to measure Linear Energy...Go to contribution page

Maria Cristina Montesi (INFN Napoli)24/02/2007, 12:00Contributed TalkIn the framework of a national project for new imaging techniques for breast cancer diagnosis we are implementing an X-ray Computed Tomography (CT) system, with a design resolution of 1 mm, on the gantry of a dedicated scintillator based single photon emission tomography (SPECT) system for breast Tc-99m imaging, to allow for anatomical co-registration of the radionuclide tomographic...Go to contribution page

Gabriela Ribeiro Pereira (Nucl. Instrum. Lab., Rio de Janeiro)24/02/2007, 12:25Contributed TalkAn X-ray Transmission Microtomography (CT) system combined with an Xray Fluorescence Microtomography (XRFCT) system was implemented in the Brazilian Synchrotron Light Source (LNLS), Campinas, Brazil. The main of this work is to determine the elemental and absorption distribution map in breast tissue samples. The experiments were performed at the X-Ray Fluorescence beamline (D09B-XRF)...Go to contribution page

Yuri Tikhonov (Budker INP)24/02/2007, 12:50Contributed TalkLast years Budker INP has been developing digital scanning low-dose X-ray systems for medical radiography based on ionization chambers. These systems provide dose ∼ 5 μSv for chest inspection (lowest dose in the world). The spatial resolution is 2 p.l./mm, dynamic range is ∼ 1000. About 300 such systems have been produced by industry and are used in Russian hospitals. Similar method...Go to contribution page
