HiReSPECT provides the highest performance and versatility available to address your preclinical imaging research needs from academic and translational research, to drug discovery and development.

The HiReSPECT is a Dual Head Small

Animal SPECT (Single Photon Emission Computed Tomography) imaging system that provides in vivo high resolution three-dimensional (3D) images of physiological functions in small laboratory animals.


Small animal imaging is an emerging field which has an impact on various biomedical research areas such as neurology, oncology, cardiology, immunology and infection biology.The pharmaceutical industries and research centers will profit from SPECT system as theyaccelerate drug and biomarker development by yielding more reliable in vivo results and cost effective study design.


Tc-MIBI SPECT image of Rat cardiac using HiReSPECT scanner. Imaging with MethoxyisobutylIsonitrile (Tc-MIBI) is the initial method of choice to detect cardiac abnormalities in cardiac imaging.


Tc-MAA SPECT image of Mice liver using HiReSPECT scanner. Imaging with MicroaggregatedAlbumin (Tc-MAA) is the initial method of choice to detect liver metastases in cancer.


Tc-99m planar image of Rat Thyroid using HiReSPECT scanner. Based on the reports of the interpretation of thyroid scan, as one of the smallest organs of rat, thyroid lobes are well depicted and distinguished from each other in the images.


HiReSPECT Image Reconstruction

The HiReSPECT sys tem uses a newly developedaccelerated iterative recons truction algorithm withadjus table percentage of resolution recovery usingaccurate modeling of collimator detector response.

Micro Deluxe Phantom images before and after Rotation-based Pixel-driven resolution recovery method.


Tc-MDP SPECT image of mice using HiReSPECT Scanner.

Imaging with Tc-methylene diphosphonate (Tc-MDP) is the initial method of choice to detect skeletal metastases in cancer.


Tc-DMSA SPECT image of mice using HiReSPECT Scanner.

Imaging with Tc-Dimercapto succinic acid (Tc-DMSA) is the initial method of choice of renal scintigraphy.

Service & Maintenance

The service & maintenance unit of Parto Negar Persia Company has been set up in 2009 at the same time as the beginning of the company's activity, and with the increase of variety and number of products of the company, this section has expanded and methods of responding to customers and customer surveys have been improved.

 Currently, 6 personnel consisting of two senior technical engineers, two technical engineers and two technical technicians are working in this department and provide their services, especially in the field of repair, maintenance and service of nuclear medical imaging systems.

It is also hoped that this year, with the appointment of Dr. Teymourian, with more than ten years of experience in the field of service and maintenance of nuclear medical systems, as the management of the service and maintenance department, the services of this department will be provided with higher speed and quality.

Providing these services in Tehran is less than 24 hours and in other cities is less than 72 hours. Due to the fact that all the products of the company are domestically produced, spare parts for all relevant parts are available in the company and the sleep time of the systems has been reduced to a minimum.
