Adult Head (Dynamic, Advanced) for X-Ray CT, US, MRI
Product Description
The Adult Head (Dynamic, Advanced) phantom is a premier medical imaging tool compatible with Ultrasound, MRI, and X-Ray/CT. This advanced model combines the complex vascular features of the Dynamic phantom with the inflatable ventricular system of the Standard model. It includes specialized temporal and suboccipital windows for Transcranial Doppler Ultrasound and features an openable/removable calvaria for easy access to the internal brain structures.
The brain parenchyma is made of an ultra-soft polyurethane material that mimics living soft tissue, with an anatomical shape derived from human MRI scans. For MRI applications, the phantom provides realistic T2 relaxation time values, making it the best fit for T2-weighted and Proton Density imaging methods. It is compatible with a wide range of contrast mediums, including Barium-sulfate, Iodine, Gadolinium, Microbubble, and Iron Oxide.
Note: By default, the phantom comes in a translucent amber appearance. A skin feature can be included upon request. Before ultrasound scanning, the skull cavity should be filled with water to act as a dura mater substitute.
Anatomy
- Skull: Realistic three-layered structure with temporal and suboccipital windows and removable calvaria.
- Brain: Grey Matter parenchyma.
- Ventricular System: Inflatable lateral, third, and fourth ventricles (fillable with liquid).
- Vascular System: Complex brain vessels (2mm, 3mm, 4mm) with incorporated Circle of Willis, one bifurcation, one stenosis, and two aneurysms.
- Connections: Vessels connected with the neck and durable plastic connectors.
- External: Alignment markings and acoustically correct skin-mimicking material.
