Abstract
A perfusion chamber for use in a phantom including a waterproof housing containing a porous material, the porous material defining fluid paths between pores and tubular channels within the porous material; and a reservoir for use in a phantom, a pump mechanism for use within the bore of an MRI scanner, a phantom for use in an MRI scanner, and a method for calibrating a scanning device.
Claims21
A pump mechanism for use within the bore of an MRI scanner, the pump mechanism comprising:
- a shielded enclosure housing a piezoelectric pump;
- a power amplifier;
- and
- a filter,
- wherein the filter is connected to the power amplifier and to ground and to the pump.
A phantom for use in an MRI scanner, the phantom comprising a closed system through with perfusate can flow comprising a pump mechanism for moving perfusate through the system, a perfusion chamber, and a reservoir, wherein the phantom comprises a germicidal device comprising a waterproof container that is transparent to UV light and around which perfusate within the phantom can flow, the waterproof container housing a UV lamp for irradiating the perfusate as it passes around the container.
A phantom for use in an MRI scanner, the phantom comprising a closed system through which perfusate can flow comprising a pump mechanism for moving perfusate through the system, a perfusion chamber, and a reservoir, wherein the pump mechanism comprises:
- a shielded enclosure housing a piezoelectric pump,
- a power amplifier, and
- a filter;
- wherein the filter is connected to the power amplifier and to ground and to the piezoelectric pump.
A phantom for use in an MM scanner, the phantom comprising a system through which perfusate can flow, the system comprising a pump for moving perfusate through the system, a perfusion chamber and a germicidal device, wherein the germicidal device comprises a UV lamp for irradiating the perfusate.
A pump assembly for use within an MM bore, the pump assembly comprising:
- a pump;
- a power amplifier coupled to the pump;
- a filter coupled between the power amplifier and the pump;
- a shield for the filter;
- and
- a ground cable for the power amplifier, coupled to the shield.
