Fig. 1 Flexible single(cid:2)detector assembly Stage ooff development The development are based on the scientific and techni(cid:2)cal reserve, created during execution of P015 and P015C STCU project by creation detector modules for experiment ALICE in CERN (. Geneva, Switzerland) The development is at a stage of laboratory tasted techno(cid:2)log(cid:2) ical structures and test structures of quality. The constructive (cid:2) technological limits and requirements to design of detector modules are determined; The analysis technical feasibility is carried out and ex(cid:2)peri(cid:2) mental samples flexible single detector assemblies are made.

As a result of performance of the given project the new con(cid:2) structive (cid:2) technological decisions single and multidetec(cid:2)tor modules on aluminium (cid:2) полиимидных cables and plates for miniature probes SPECT and PET tomography will be devel(cid:2) oped. The new miniature multidetector probes (up to 10 detectors) allow increasing sensitivity tomo(cid:2)graphiey up 16(cid:2)40 times. Array detector modules developed in the project based on assembly CsJ (Tl) scintillators with silicon pin(cid:2)photodiodes will provide decrease a energy threshold at radiation registra(cid:2) tion up to 17(cid:2)30 keV, a good energy resolution (~18(cid:2)19 %) for gamma (cid:2) quantum with energy up to 60 keV. Will be made and tested prototypes single and multidetector modules for med(cid:2) ical miniature probes for external and rectal application, which will allow to receive the image of organs with the resolution in 4(cid:2)5 time higher than in existing Compton systems. Innovative aspect and main advantages Novelty of the project, first of all, is consists in making the pro(cid:2) totype miniature multilayer multidetector (7(cid:2)10 re(cid:2)ceivers of radiation) probe of rectal application for early stages of diag(cid:2) nostics prostate cancer. The detector block also will be created on the basis of system « scintillators CsJ (Tl) (cid:2) silicon pin (cid:2) photodiodes array(cid:2) charge(cid:2) sensitive amplifier». It exceeds system «scintil(cid:2)lators BGO – photoelectric multiplayer (cid:2) electronic sub(cid:2)block» in a lot of parameters: higher length run of a gamma – quantum at E=511keV (for BGO ~ 1,1см, CsJ (Tl) ~ 1.85см); rather low cost (on 30 50 % lower than cost of detector block BGO). In designs of new detector modules the advanced com(cid:2) ponents (array silicon radiation receivers, scintillator photo(cid:2) diode detector blocks, fast multichannel low – noise chips with the step of pins less than 50 microns) will be used. The application new precision commutation elements (cid:2) flexible cables and plates on a basis multilayer aluminium – polyim(cid:2) ide structures will allow essentially to minimize dimensions and weight of probes, considerably to improve their charac(cid:2) teristics and completely to exclude wire assembly, that es(cid:2)sen(cid:2) tially simplify process of assembly multilayer multidetec(cid:2)tor structures. Development of new high(cid:2)sensitivity miniature multide(cid:2)tector probes, their using close to investigated parts of body allow to decrease radial influence on the patient, and the increase of the energetic and spatial resolution will ensure an opportunity of diagnostics cancer tumor at a cage level.
