Abstract Various materials and compounds have been used in the design of diffusion-weighted magnetic resonance imaging (DWMRI) phantoms to mimic biological tissue properties, including diffusion. This review thus provides an overview preparations various DW-MRI available relation limitations strengths materials/solutions fill them. The narrative conducted from relevant databases shows that synt...

Laser optoacoustic imaging is a promising diagnostic technique for early breast cancer detection. Capability of laser optoacoustic imaging for visualization of small spherical tumor phantoms located within the bulk collagen gels was studied. The experiments were performed with breast phantoms made of optically turbid collagen gel. Optical properties of the phantom resembled the optical properti...

Materials for solid photoacoustic breast phantoms based on poly(vinyl alcohol) hydrogels are presented. Phantoms intended for use in photoacoustics must possess both optical and acoustic properties of tissue. To realize the optical properties of tissue, one approach was to optimize the number of freezing and thawing cycles of aqueous poly(vinyl alcohol) solutions, a procedure which increased th...

Benchtop studies are often used to evaluate cardiac ablation techniques, and commonly utilize ex-vivo animal tissues. While widely available, tissues do not consistently replicate live atrial tissue physical properties, adding variability. Tissue mimicking phantoms have been in non-cardiac studies, but their mechanical electrical properties may mimic tissue. Furthermore, analysis of lesions has...

The aim of this work was to develop a method to manufacture oncological phantoms for quantitation purposes in 18F-FDG PET and DW-MRI studies. Radioactive and diffusion materials were prepared using a mixture of agarose and sucrose radioactive gels. T2 relaxation and diffusion properties of gels at different sucrose concentrations were evaluated. Realistic oncological lesions were created using ...

Ultrasound phantoms are generally of two types. One mimics the acoustic properties of tissue (with regard to the speed of sound, average attenuation, etc.). The main purpose of the other is to approximate the sonographic appearance of tissue. The latter is often used as a biopsy training aid. Those which mimic the acoustic properties of tissue have been constructed of agar with suspended graphi...

Temperature can be used as clinical marker for tissue metabolism and the detection of inflammations or tumors. The use magnetic resonance imaging (MRI) monitoring physiological parameters like temperature noninvasively is steadily increasing. In this study, we present a proof-of-principle study MRI contrast agents (CA) absolute concentration independent imaging. These CAs are based on azoimidaz...

introduction accurate estimation of the absorbed dose in radiosensitive organs, located away from the target volume during radiotherapy, is one of the main reasons for the development of reference phantoms. the international commission on radiological protection (icrp) reference phantoms can provide a more realistic view of the human anatomy in comparison with the previously used mathematical p...
