Introducing  small animal imaging devices:

 

Small animal PET:

An animal PET designed and  constructed for PET imaging of small animals such as rats and mice.this system evaluates the metabolic and physiological functions of the animal body by estimating the distribution of radiopharmaceutical in the animal body .the system can be used to diagnose,evaluate ,estimates of progression of tumors,lesions and organs,function can be used.

 

 

Small animals  SPECT:

The HiReSPECT is a small animal imaging system that provides researcher with high resolution 3D images of the physiological function of animal organs.the function of this device is that the radiopharmaceutical is injected into the rat vein, and then the device with its detector system provides a number of two dimensional  images of different angles in the 360 degree range of rats.then a computer software,using the data obtained in a three_ dimensional image ,reconstructs the mode and extent of the radiopharmaceutical  dispersion in the rat .using the obtained information ,one can comment on the effectiveness of the used radiopharmaciuticals  and  the target cells in the best way.

Molecular fluorescence device of small animal:

Molecular fluorescence tomography system with the aim of small animals imaging in the clinical and research fields can be used to identify metabolic pathways, issue structure and small animal studies.in this type of imaging,the study is at the molecular and even sub_molecular level in a non_invasive and non_invasive manner.the capabilities of this type of imaging can be used to diagnose and even treat some diseases ,such as cancer and cardiovascular disease.also , this technique can be used to improve the treatment and optimization of drugs in pre_clinical trials and then clinical users.
