MEDICAL DIAGNOSTICS DEVICE Russian patent published in 2006 - IPC A61B6/03 H05G1/00 

FIELD: biology; medicine.

SUBSTANCE: device can be used for diagnosing state of internal organs. Device has narrow discontinuous radiation beam former with sweep, radiation detector, synchronization unit, drive, master oscillator, counter, analog-to-digital converter, processor and monitor. Radiation detector is made in form of M identical layers disposed one after another in the direction of radiation propagation. Any layer is made in form of N isolated parallel linear arrays; each of each consists of K pin-diodes connected in parallel, back-biased and disposed in one line along line of sweep of the beam. All M linear arrays being disposed layer by layer and having similar order numbers are connected to each other and to information inputs of analog-to-digital converter. Count input of counter is connected with output of master oscillator. Control input of the counter is connected with output of sweep radiation beam former. Output of pulse counter is connected with the second information input of processor. Clock output of counter is connected with control inputs of analog-to-digital converter. Radiation detector is used which detector has high efficiency of X-ray radiation energy conversion to electric signal. Design of the detector proposed allows using counter which provide simple determination of spatial location of read-out image element (pixel) and its correspondence to definite area (zone) of object to be diagnosed.

EFFECT: reduced dosage load; increased speed of operation when reading information out.
