In part, the disclosure relates to computer-based methods, devices, and systems suitable for detecting a delivery catheter using intravascular data. In one embodiment, the delivery catheter is used to position the intravascular data collection probe. The probe can collect data suitable for generating one or more representations of a blood vessel with respect to which the delivery catheter can be detected.

Intravascular imaging and guide catheter detection methods and systems

The disclosure relates, in part, to computer-based visualization of stent position within a blood vessel. A stent can be visualized using intravascular data and subsequently displayed as stent struts or portions of a stent as a part of a one or more graphic user interface(s) (GUI). In one embodiment, the method includes steps to distinguish stented region(s) from background noise using an amalgamation of angular stent strut information for a given neighborhood of frames. The GUI can include views of a blood vessel generated using distance measurements and demarcating the actual stented region(s), which provides visualization of the stented region. The disclosure also relates to display of intravascular diagnostic information such as indicators. An indicator can be generated and displayed with images generated using an intravascular data collection system. The indicators can include one or more viewable graphical elements suitable for indicating diagnostic information such as stent information.

Stent detection methods and imaging system interfaces

Data of a vector storage request pertaining to one or more disjoint, non-adjacent, and/or non-contiguous logical identifier ranges are stored contiguously within a log on a non-volatile storage medium. A request consolidation module modifies one or more sub-requests of the vector storage request in response to other, cached storage requests. Data of an atomic vector storage request may comprise persistent indicators, such as persistent metadata flags, to identify data pertaining to incomplete atomic storage requests. A restart recovery module identifies and excludes data of incomplete atomic operations.

Systems, methods, and interfaces for vector input/output operations

An apparatus, system, and method are disclosed for data management. The method includes writing data in a sequential log structure. The method also includes receiving a time sequence request from a client. The method further includes servicing the time sequence request based on a temporal order of the data in the sequential log structure.

Time sequence data management

Apparatuses, systems, and methods are disclosed for managing configuration parameters for non-volatile data storage. A control module is configured to limit erase dwell times for blocks of a non-volatile memory medium to satisfy a threshold. A block classification module is configured to group blocks of a non-volatile memory medium based on retention times for the blocks. A block access module is configured to access at least one group of blocks using a read voltage threshold selected based on a grouping.

Configuration parameter management for non-volatile data storage

A storage controller is configured to implement an atomic storage operation comprising a plurality of separate storage operations on a non-volatile storage medium. The storage controller may store persistent indicators to identify data that pertains to the atomic storage operation. An invalid shutdown may occur before the atomic storage operation is complete. A restart and recovery operation comprises a first scan of the non-volatile storage medium to identify data of the failed atomic storage operation. A physical trim note is stored on the non-volatile storage medium to identify the data of the failed atomic storage operation. The data may be identified by media address. Storage metadata is reconstructed in a second scan, which excludes the data and/or operations of the failed atomic storage operation.

Systems, methods, and interfaces for managing persistent data of atomic storage operations

Techniques are disclosed relating to processing data in a storage controller. In one embodiment, a method includes receiving data at a storage controller of a storage device. The method further includes processing data units of the data in parallel via a plurality of write pipelines in the storage controller. The method further includes writing the data units to a storage medium of the storage device. In some embodiments, the method may include inserting header information into the data for a plurality of data units before processing, and the header information may include sequence information. In some embodiments, writing the data units may include writing according to a sequence determined prior to processing the data units.

Data storage controller with multiple pipelines

Embodiments are disclosed relating to garbage collecting storage blocks in a storage device. In one embodiment, data is selected for relocation from a storage block in a storage device during reclaiming of the storage block. The data may be selected based on metadata that identifies whether data is valid at a time when the reclaiming is initiated. In some embodiments, prior to relocating data from the storage block, the metadata is captured from a data structure that identifies whether data on the storage device is valid. In one embodiment, a determination of whether the selected data has become invalid due to other data that is stored during the reclaiming is made. In some embodiments, in response to determining that the selected data has become invalid, the selected data is specified as invalid in the data structure.

Storage device metadata synchronization

Intravascular imaging system interfaces and stent detection methods

Apparatuses, systems, methods, and computer program products are disclosed for interrupting storage operations. An integrated circuit chip comprising non-volatile memory, the integrated circuit chip configured to, determine a number of portions into which a storage operation is to be split; pause execution of the storage operation from within the integrated circuit chip according to the determined number of portions; execute one or more other storage operations on the integrated circuit chip while the storage operation is paused, each of the one or more other storage operations having a shorter duration than the storage operation; and continue the paused storage operation in response to a trigger.

Storage operation interrupt

A storage layer is configured to store data at respective offsets within storage units of a storage device. Physical addresses of the data may be segmented into a first portion identifying the storage unit in which the data is stored, and a second portion that indicates the offset of the data within the identified storage unit. An index of the data offsets (e.g., second portions of the physical addresses) may be persisted on the storage device. The first portion of the address may be associated with logical addresses of the data in a forward index. The forward index may omit the second portion of the physical addresses, which may reduce the memory overhead of the index and/or allow the forward index to reference larger storage devices. Data of a particular logical address may be accessed using the first portion of the physical address maintained in the forward index, and the second portion of the media address stored on the storage device.
