During 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...

We 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...

Radiotherapy, 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...

Boron 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...

A 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....

Astronauts 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...

In 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...

An 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)...

Last 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...
