Max 4000 provides immediate measurements of even the smallest
volume ion chambers such as those used in IMRT or stereotactic
radiosurgery. For example, the MAX 4000 can capture and display
the signal from a 0.009 cc ion chamber, giving a typical
reading of 8.001 pA.
sensitivity and a wide range makes the MAX 4000 the electrometer
of choice for all brachytherapy measurements. It provides
immediate measurements of even the lowest activity isotopes.
For example, a 0.27 mCi iodine seed, measured in the HDR 1000
Plus Well Chamber, gives a typical signal of 1.458 pA. It
can also measure 10 Ci and higher iridium sources.
MAX 4000 works exceptionally well with ion chambers typically
used for data acquisition in water phantoms and with chambers
used for quality assurance tests.
versatile MAX 4000 is ideally suited for mammographic, conventional
radiology and CT scanning applications.
