liver transplant surgery

1. Introduction:

The only treatment available for liver failure is liver transplant surgery; but donor organs are difficult to obtain, and the procedure, which is expensive and complex, is frequently unsuccessful.

A workable artificial liver is desperately needed. Unlike the heart and the kidneys, the liver is able to regenerate; many people who have suffered liver damage would survive if they could be supported by an artificial liver until their own livers heal. The device could also ....etc

A bioartificial liver system is described that incorporates a cell reservoir and hepatocyte spheroids to both increase the number of and longevity of cells in the system.spheroid aggregates are formed from isolated hepatocytes using a method described here.
SUMMARY
The invention provides a bioartificial liver system with an increased number of hepatocytes and the ability to maintain normal liver metabolism during continuous operation due to which systems of the invention can improve the efficiency of exvivo liver assistance provided t ....etc

Objective

In the recent years liver segmentation from computed tomography scans has gained a lot of importance in the field of medical image processing since it is the first and fundamental step of any automated technique for the automatic liver disease diagnosis, liver volume measurement, and 3D liver volume rendering.

Methods

In this paper we report a review study about the semi-automatic and automatic ....etc

Blood tests look at liver function and levels of tumor markers (certain substances which are linked to specific types of cancer). Liver tumors will often show on an ultrasound scan but full assessment requires a CT (computerized tomography) scan or MRI (magnetic resonance imaging) scan.
n general, the imaging appearances of liver metastases are nonspecific, and biopsy specimens are required for histologic diagnosis. CT is the imaging modality of choice for evaluating liver metastases. This preference is largely attributable to the effects of t ....etc

The interface between different fields is believed to be fertile ground for breakthrough research. The interface between the emerging fields of biotechnology and nanotechnology is particularly interesting. The possibilities for new fruit are diverse: biotechnology offers new approaches for self-assembly of structures at the nanoscale, while nanotechnology offers new methods for probing and accessing biological systems. In this talk, I will discuss research in this new frontier in my group, including 1) self-assembly of 2D nanocomponent arrays b ....etc

liver segmentation matlab source code

Abstract

Computed tomography (CT) images have been widely used for diagnosis of liver disease and volume measurement for liver surgery or transplantation. Automatic liver segmentation and volume measurement based on the segmentation are the most essential parts in computer-aided diagnosis for liver CT as well as computer-aided surgery. However, liver segmentation, in general, has been performed by outlining the medical image manually or segmenting CT images semi-automatically because surface features of t ....etc
