The Clinical Application Of Different Types Of Flat Panel Detectors

Due to the impact of DQ E on image contrast, spatial resolution affects the image's ability to distinguish details. In photography, different types of flat panel detectors should be selected based on different examination sites. For examinations such as the chest, the focus is on observing and distinguishing the density of different tissues, therefore the requirement for density resolution is relatively high. In this case, it is advisable to use the DR of an indirect conversion flat panel detector, as it has a higher DQ E ratio and is easier to obtain images with higher contrast, which is more conducive to diagnosis; For examinations of areas such as limb joints and mammary glands, it is necessary to have high imaging accuracy and spatial resolution requirements. Therefore, it is advisable to use DR with direct conversion of flat panel detectors to obtain images with high spatial resolution. The vast majority of manufacturers' digital breast machines use direct conversion flat panel detectors, precisely because breast photography requires high spatial resolution, and only direct conversion flat panel detectors can meet the corresponding requirements.
