Jual Level Controller : Monitor Unit


Level indication, level-to-volume conversion, signal conversion


Monitor Unit MP2000
  • Applicable to a wide power supply range (100 to 240V AC)
  • For relay contacts, operation (high/low), hysteresis or fail-safe function are programmable
  • Non-volatile memory retains settings in the event of power failure
  • Volume indication as well as level indication
  • Bar graph and 7 segment 4 digit display for level/volume indication
  • Simulation (4 to 20mA DC) available for loop check
  • Power, input and output are isolated.
Monitor unit A monitor unit (MU) is a measure of machine output from a clinical accelerator for radiation therapy such as a linear accelerator or an orthovoltage unit. Monitor units are measured by monitor chambers, which are ionization chambers that measure the dose delivered by a beam and built into the treatment head of ... Monitor Units A single monitor unit is the amount of charge recorded in the ionisation chamber mounted in the head of the linear accelerator which correlates with a dose of 1 cGy delivered to a water phantom under reference conditions. This is an important measurement, as the output of the linear accelerator can only be read in charge ... Calculation Of Monitor Units A monitor unit is a measurement of ionisation occurring in a treatment beam within the treatment head. One monitor unit is typically equal to a specific dose of radiation, at a specific depth in a water phantom, for a beam of a particular energy, with a particular field size and at a certain distance from the target. Monitor units ...

Monitor unit calculations for external photon and electron beams Monitor unit calculations for external photon and electron beams: Report of the AAPM Therapy Physics Committee Task Group No. 71. John P. Gibbonsa). Department of Physics, Mary Bird Perkins Cancer Center, Baton Rouge, Louisiana 70809. John A. Antolak. Department of Radiation Oncology, Mayo ... [PDF]Monitor Unit Calculations for External Photon and Electron  contribute to both random and systematic deviations in dose delivery, including daily patient setup, target delineation, and dose calculation. The accurate determination of dose per monitor unit (MU) at a single calculation point is an essential part of this process. There are many methods used ... Monitor unit calculations for external photon and electron beams A protocol is presented for the calculation of monitor units (MU) for photon and electron beams, delivered with and without beam modifiers, for constant source-surface distance (SSD) and source-axis distance (SAD) setups. This protocol was written by Task Group 71 of the Therapy Physics Committee of ...

A procedure for calculation of monitor units for passively scattered ‎The purpose of this study is to validate a monitor unit (MU) calculation procedure for passively scattered proton therapy beams. The output dose per MU (d/MU) of a therapeutic radiation beam is traditionally calibrated under specific reference conditions. These conditions include beam energy, field size, suitable depth in ... Comparison of monitor units calculated by radiotherapy treatment ...  Comparison ofmonitor units calculated by radiotherapy treatment planning system and an independent monitor unitverification software. Sellakumar P(1), Arun C, Sanjay SS, Ramesh SB. Author information: (1)Department of Radiation ... Analyzing the characteristics of 6 MV photon beam at low monitor unit Analyzing the characteristics of a low monitor unit (MU) setting is essential, particularly for intensity-modulated techniques. Intensity modulation can be achieved through intensity-modulated radiotherapy (IMRT) or volumetric-modulated arc therapy (VMAT). There is possibility for low MUs in the segments of IMRT and and any other persons on campus exposed to hazardous materials and situations, in accordance with Israeli laws and Institutions policy. All new employees must undergo a health evaluation, and persons whose work involves hazardous ...
