Photoacoustic, ultrasound multimodal imaging

Photoacoustic imaging based on specific endogenous or exogenous light absorbing substances such as pigments, blood vessels, lipids, and nanoprobes

Ultrasound imaging based on acoustic impedance differences

Micron-level resolution, millimeter-level imaging depth

Photoacoustic microscopy breaks through the diffraction limit of traditional optical imaging,and the imaging depth is up to 6 mm.

At deeper imaging depths,high resolution at the optical level can still be maintained with an accuracy of 3 μm

3D image information is analyzed layer by layer

Through the real-time 2D tomographic data display overlay, the 3D structural images of the local tissue can be further obtained, and the 2D and 3D images can be further analyzed by using data processing software.

Non-invasive, label-free imaging

Only a small amount of water (couplant) is applied to the imaging site to match the signal, and non-invasive imaging of the test site can be achieved without the injection of contrast agent.

Heating-anesthesia-integrated small animal fixation table

Integrated heating-anesthesia device specifically designed for better protection of model animals.

Non-invasive, label-free imaging

Only a small amount of water (couplant) is applied to the imaging site to match the signal, and non-invasive imaging of the test site can be achieved without the injection of contrast agent.
