Measurement apparatus

摘要

A method for determining biological indicators, the method including, in a processing system causing at least one radiation attenuation measurement to be performed and determining at least one first biological indicator using determined radiation attenuation. In addition to this, method includes causing at least one impedance measurement to be performed and determining at least one second biological indicator using a determined impedance measurement.

1. A method for use in determining a presence, absence or degree of lymphoedema using a processing system, comprising the steps of:
a) performing at least one radiation attenuation measurement; wherein the processing system uses a signal generator to control a radiation source for performing the radiation attenuation measurement; b) determining limb volumes for a subject using a determined radiation attenuation; wherein a detector measures an intensity of transmitted radiation and returns the intensity of transmitted radiation to the processing system for determination of limb volumes for the subject; c) performing at least one impedance measurement; wherein the processing system uses a controller to control a signal generator and sensor for performing the at least one impedance measurement; d) determining fluid levels in the subject using a determined impedance measurement wherein the controller returns the at least one impedance measurement to the processing system, or wherein the controller returns at least one derived impedance parameter value to the processing system for determining fluid levels in the subject; and, e) using the processing system to determine an indication of the presence, absence or degree of lymphoedema by:
i) using the limb volumes to detect the presence or absence of lymphoedema;ii) using the fluid levels to detect the presence, absence or degree of lymphoedema; and,iii) detecting that lymphoedema is at an early stage if lymphoedema is detected using the fluid levels but not using the limb volumes.
