Frequently Asked Questions

Debbie has a tube in her lung that would interfere with the tube.

Yes, no obstruction in Wounded Willy.

Yes, the arteries are more visible.

1.005-1.025 g/cc

50-150 Kvp

Yes, but it is necessary to be aware of the internal organ locations.

Those who would like to see the bones and organs prefer the transparent version. Those who want their students to know the location of the bones and organs without being able to see them, prefer the opaque version.

Yes, you can stick the region but you can’t inject or do pressure studies.

No

No. The phantom weighs 70-75 lbs. In a crate the weight is about 165lbs.

Gel material the same as the injectable soft tissues.

It can be used for neuro and ortho applications but not for vertebral plasty, spinal cord stimulation or pumps.

Removal of skin, then use pliers to remove.

Yes

Tissue-equivalent material.

They are inflated.

The materials are selected to provide radiographic and radiation dosimetric equivalence to the modeled material (i.e., muscle looks and responds in radiation in a manner very close to human muscle tissue, bone, etc.)

The present product simulates generic free breathing.

Yes

The target moves Sup-Inf (Cranio-Caudal) about 25-30mm with a 7˚ twist around the direction of motion.

No

Yes. The maximum size holder is 1¼ x 1 ¼ x 1¼

The stroke is adjustable up to 25mm, using the Stroke dial in the software. The phantom motion depends on applied pressure waveform, in particular in the exhalation portion of the cycle. The system is open-loop where the applied pressure inflates the phantom and when rapidly reduced, the phantom “exhales” under the force of the elastic materials in the chestwall (virtual intercostal muscles). When the pressure in the lung volume is decreased slowly, the motion follows the (decreasing) applied pressure. The maximum applied pressure is set at the factoryfor a chestwall motion of approximately 1.5-2cm with the white rod in place. There is a simple adjustment in the pump box to customize this to your needs. The lung volume corresponds to size for a 5 feet, 9 inches (175 cm) tall, 162 lbs (73.5 kg) male. All of the RSD materials in the imagable volume of the phantom are equivalent to natural bone and soft tissues. The tumor/target speed travels the full stroke in/out (i.e. 50mm = twice the 25mm max stroke) in one breathing cycle, so that the tumor velocity also depends on respiration rate: tumor velocity (cm/sec)= Breaths per mionute *{ 50mm/[10(mm/cm)*60(sec/min)] }. So for a 12bpm rate, the tumor velocity is one cm/sec.

The tumor is designed to rotate 7 degrees upon full extension (full stroke). Different pitches can be provided on special order.

Generic computer requirements are:

• CPU: Intel family
• OS: Microsoft Windows 2000/XP/Vista
• IO: one USBv1.1 or higher (connects to the RS1500 PC interface box containing the MCC_USB-1208LS.)
• RAM: The installed software uses minimal RAM, so a system configured for the OS above is sufficient.

Disk:

• The installed software requires at most 667MB (i.e. one CD-full) of hard disk space.
• Most of this is documentation for MCC devices.
• One can elect not to skip install the MCC documentation.
• The RSD RS1500 application is less than 0.5MB.
• Upper bound: diskspace approx 130MB: RS1500 app, MCC driver(s), LabView_RTE

The present product simulates generic free breathing. In progress is a system to train the phantom control software to reproduce patient chest motion from that recorded via commercial devices adjunct to respiratory gated imaging. Chest motion is represented as anterior displacement at a given anatomical location defined by the user and on a patient-specific basis.

Yes

Yes

5, 10 and 165 lbs.

No
