An electromagnetically shielded electronic assembly is disclosed in which electromagnetic shielding and filtering is provided to prevent unwanted radiofrequency energy, generated from an electric device residing within the assembly, from radiating externally. The electronic device resides within a primary shielded region and is coupled, through a filter, to an external electrical conductor that extends externally from the shielding. The filter resides within a secondary shielded region that is electromagnetically shielded from the primary shielded region, with the filter electrically contacting the electromagnetic shielding within the secondary shielding region. The electronic device is housed without being brought into electrically conductive contact with the electromagnetic shielding, such that radiofrequency signals generated by the electronic device can be directed, within a blocking frequency band of the filter, to the electromagnetic shielding, thereby reducing or preventing the internally generated radiofrequency energy, within the blocking frequency band of the filter, from radiating externally.

Electromagnetically shielded electronic assembly for noise reduction during magnetic resonance imaging

Systems and methods are provided for delivering images to a patient before and/or during a medical procedure in which a patient is translated on a table relative to a gantry. In various example embodiments, images are projected to the patient while preserving the projected field size during table motion, thereby potentially reducing patient anxiety by providing a more immersive patient viewing experience. In some embodiments, the projected field size is maintained by a display system that is secured to the table such that both a projector and a projection screen are fixed relative to the table, and relative to the patient, during translation of the table. In some example embodiments, a reduction in patient anxiety may be achieved by projecting images as virtual images that are perceived by the patient as residing at a depth that lies beyond the confined spatial region in which the patient resides.

Systems and methods for displaying images to patient residing on movable table during medical imaging or therapeutic procedures

The present disclosure provides communication systems and devices for use in noise environments, such as during magnetic resonance imaging (MRI). In some embodiments, a communication headrest is provided that consists of a headrest that supports a patients' head, an optional bone conduction microphone, and one or more vibration actuators. The headset makes contact with noise-isolating earplugs worn by the subject such that vibrations generated by the vibration actuators are transferred through the earplug, via acoustic conduction, to enable the patient to hear audio content while the earplugs provide passive noise protection by occluding the ear canal. In other embodiments, active earplug devices are provided in which an acoustic transducer is contacted and supported by a noise isolating earplug, such that when the earplug is inserted into the ear canal, the acoustic transducer is brought into acoustic conductive communication with tissue surrounding the ear canal, facilitating acoustic communication through bone conduction.

Systems and devices are provided in which an RF wireless bridge is employed to facilitate indirect transmission of communication signals between external devices located outside of an electromagnetically shielding enclosure within internal devices located within the enclosure, via the intermediate transmission of RF waves through an RF attenuating window forming a portion of the enclosure. The wireless bridge is formed from a first RF communication device located within the electromagnetically shielding enclosure, and a second RF communication device located outside of the enclosure, where the two RF communication devices are positioned with sufficient proximity such that the wireless bridge facilitates indirect communication through the RF attenuating window despite attenuation of RF energy by the RF attenuating window. In another example embodiment, the electromagnetically shielding enclosure may enclose at least a portion of the first RF communication device to reduce noise that could impact the performance of the magnetic resonance scanner.

Apparatus and method for using radio frequency coil systems for magnetic resonance imaging within an open architecture apparatus is provided. The MRI coil system includes a support structure with an open architecture in which secondary support structures, compression systems and plates containing RF coil systems may be introduced. These structures and RF coils can be moved relative to the patient, or removed entirely from the system. In one embodiment the system consists of a tabletop coil system, while another embodiment consists of a dedicated stretcher design.

Open architecture imaging apparatus and coil system for magnetic resonance imaging

This invention discloses a method and apparatus to deliver medical devices to targeted locations within human tissues using imaging data. The method enables the target location to be obtained from one imaging system, followed by the use of a second imaging system to verify the final position of the device. In particular, the invention discloses a method based on the initial identification of tissue targets using MR imaging, followed by the use of ultrasound imaging to verify and monitor accurate needle positioning. The invention can be used for acquiring biopsy samples to determine the grade and stage of cancer in various tissues including the brain, breast, abdomen, spine, liver, and kidney. The method is also useful for delivery of markers to a specific site to facilitate surgical removal of diseased tissue, or for the targeted delivery of applicators that destroy diseased tissues in-situ.

Patient support for prone imaging and intervention table

A modular intervention bed for use with a medical tomographic imaging system having an associated patient transport device and an imaging device. The modular intervention bed comprises a trestle configured to engage a patient transport device, with the trestle having an intervention area. A patient couch movably mounted on the trestle, with the patient couch defining an opening corresponding to the intervention area. The couch comprises a plurality of patient mats with each mat connected to at least one other mat, a pair of rollers mounted on each mat in a spaced apart relationship with each roller proximate an outside edge of each mat. The modular intervention bed can be reconfigured by adding or removing a mat thereby moving the intervention area and opening to correspond with the portion of a patient under investigation during an intervention procedure guided by a medical tomographic imaging system.
