Well detector with 2? lead for PET

1024-channel Multi-Channel Analyzer

Laserprinting capability

The SpectroAnalyzerTM is a compact single or dual-channel counting instrument used for gamma counting, and is also available with a 1024-channel MCA. It contains a precision pulse height analyzer and high voltage supply, both microprocessor controlled.
The pulse height analyzer setting is accomplished through a menu and selects an energy region of interest. When the proper high voltage is applied to the detector, the PHA is calibrated directly in keV. Optional spectrum/MCA includes auto-calibration.

Output signals from the pulse height analyzer are totaled by the scaler, which can operate in either a preset count or preset time mode, and background count is automatically subtracted. Efficiency can be measured or entered, and activity can be displayed in disintegrations perminute (DPM).

A serial computer interface (RS-232) for input and output allows a computer to change settings, and count data can be transferred to the computer for printing or saving to disk.

Tested to EN61010-1 and equivalent UL/CSA standards for CAN/USA certification by TUV Rheinland, and tested to EMC standard EN61326 for CE conformity.

AccuSync Medical Research Corporation is ISO13485 registered designer and manufacturer of medical devices and related instruments in nuclear medicine.

  • Resolving Time

    One microsecond pulse pair. The overall resolving time of the scaler is limited by the input circuits and the necessary integration time in the detector for adequate pulse height resolution.

  • Time

    The microprocessor-controlled timer indicates elapsed time up to 1000 minutes.

  • PresetTime

    Time can be preset to any number up to 1000 minutes using the menu.

  • PresetCount

    Number of counts from100 to 10 million can be preset by using the menu.

  • Background

    Automatic subtraction of background count.

  • Digital Rate Meter

    Indicates 0-10 million counts per minute with automatic change of range.

  • Pulse Height

    Five energy ranges from 500 to 2000 keV in steps of 500 keV are provided.

  • Window Setting

    1) Upper and lower level discriminator independently controlled from 0 to 100%.

    2) % window. Lower level is set as the reference in keV’s. Window is set as the % of this reference.

    3) Symmetrical window. Lower level is set as the reference in keV’s. Window is set symmetrical about this reference.
