Gastrointestinal tract simulation system and compartment therefor. The compartment comprising a vessel having an open top surrounded by a peripheral edge portion and an air-tight lid system configured to be placed onto the peripheral edge portion. The lid system comprises a body with a plurality of passageways extending through the body and providing access to the interior of the vessel, the plurality of passageways comprising passageways for fluid transfer tubes and passageways for mounting at least one sensor component. The lid system is provided with releasable sealing elements for sealing the plurality of passageways and at least one pressing element which is common to at least a number of the sealing elements and configured for applying pressure to each of the respective sealing elements to effect the sealing of the respective passageways.

A multi-modal visualization system (MMVS) is provided, which may be used to analyze and visualize bioimaging data, objects, and pointers, such as neuroimaging data, surgical tools, and pointing rods. MMVS can integrate multiple bioimaging modalities to visualize a plurality of bioimaging datasets simultaneously, such as anatomical bioimaging data and functional bioimaging data.

A lung phantom unit for radiotherapy according to an embodiment of the present disclosure may arrange, at a location not affected by a magnetic field, a phantom driving cylinder and a driving device which may move a lung mimic and a tumor mimic in a lung simulation block. The lung phantom unit may be used for general purpose even as a phantom for MRI-based and CT image-based radiotherapy. Since lung and tumor motions are implemented by air injection, it may be possible to precisely measure the motion and volume change of a lung according to subtle changes in air pressure so that customized radiotherapy suitable for a patient having various breathing patterns is possible.

Aspects of the present disclosure relate to a wearable medical trainer. The medical trainer may be embodied as a device for simulating wounds and injuries received during a trauma event, or otherwise. Aspects of the present disclosure further relate to a medical training device for Trauma Emergency Casualty Care and Tactical Combat Casualty Care (TCCC). A wearable device may be worn by a live human (e.g., trauma actor) or simulated body (e.g., full/partial manikin, drag dummy, etc.). The medical trainers disclosed herein may include one or more simulated injuries, which may be operational or merely to provide more realism. The medical trainers disclosed herein may further include features directed toward to internal and/or external trauma injuries.

The present disclosure, when used by a live actor, may allow users to safely simulate hemorrhaging in some of the most challenging blood vessels in the most challenging anatomical locations such as the carotid artery, the axillary artery, and the femoral artery. The present disclosure may further provide the ability for users to safely perform hemorrhage control procedures, such as compression and ligation. The simulated wound of the present disclosure may be compressed to control hemorrhage. The simulated wound receptacle of the present disclosure may be packed with hemostatic or simple gauze to control hemorrhage. The simulated blood vessel of the device may be ligated with hemostats or other ligating instruments or material and bandaged with pressure dressings to control hemorrhage.

A method for customizing an interactive control boundary includes positioning a virtual implant model relative to a virtual bone model based on a user input, and extracting reference feature information associated with the virtual implant model, wherein the reference feature information describes one of a point, a line, a plane, and a surface associated with the virtual implant model. The method further includes mapping the extracted reference feature information to the virtual model of the bone, and receiving information indicative of a positional landmark associated with the bone, then estimating an intersection between the positional landmark and the mapped reference feature and generating a virtual boundary based, at least in part, on the estimated intersection between the positional landmark and the mapped reference feature.
