“…The paper introduces properties of the thin detectors and spectroscopic characterization of manufactured detectors. The advanced process technology relies on the process steps to fabricate insulated through wafer interconnections (TWI) or vertical electrodes into the detector bulk [11]. The critical process steps are the ICP-etching, the polysilicon filling of the etched holes and the planarization of the wafer surfaces after the polysilicon deposition.…”

VTT has two decades experience on the manufacturing and design of the silicon radiation detectors. The activities cover a range of industrial devices as well as the devices for the physics experiments. The paper gives an overview on the new solid state detector development activity at VTT that comprise advanced X-ray photo diodes, through wafer interconnections for the photo diode arrays, thin silicon strip detectors, active-edge strip and pixel detectors with different biasing schemes, and full 3D 1 mm thick active edge silicon detectors.

“…CT images are also used as basis for planning radiotherapy cancer treatment. CT is also often used to follow the course of cancer treatment to determine how the tumor is responding to treatment [14][15][16]. CT imaging provides both good soft tissue resolution (contrast) as well as high spatial resolution.…”

A medical image gray value and coordinate real-time statistics methods based on CT slice data is proposed. By this new method, the gray and three-dimensional coordinate of biomedical image can be successfully observed. We constructed a curve on CT image. The curve could be arbitrary moving, and gray value or 3D coordinate on the curve will be displayed simultaneously. We have obtained the perfect results of gray and coordinate on CT image in DICOM format. Experiment results shows proposed methods is a convenient and flexible approach and it can achieve gray and coordinate real-time interactive display on CT image. This method can assist doctors to make better and more accurate diagnosis.
