IMAGING METHOD AND APPARATUS

摘要

An imaging system comprises a sensor arrangement for detecting an acoustic signal which emanates from a sample; and means for analysing the sensor arrangement output signals to derive a property for different portions of the sample. A reflector arrangement reflects a portion of the signal generated within the sample which is not directed to the sensor arrangement, such that it is reflected to the sensor arrangement. The sensor arrangement output signals are processed over a time period which covers the direct receipt of the signal generated within the sample by the sensor arrangement as well as the reflected portion of the signal generated within the sample.
