## Biomedical Signal Processing Toolbox-BIOMEDICAL SIGNAL ANALYSIS

Abstract.

This article describes a biomedical signal processing (BSP) toolbox for the analysis
of physiologic signals. The BSP toolbox is designed to enable researchers to conduct
preliminary analysis of physiologic time series, such as the electrocardiogram (ECG),
intracranial pressure (ICP), arterial blood pressure (ABP), and oxygen saturation (SpO2).
The toolbox includes detection algorithms for the ECG and pressure waveforms, spectral
analysis, nonlinear filtering, multi-signal analysis, and nonstationary signal visualization.
The following sections discuss the functionality of this toolbox and provide examples of its
application.

## INTERVIEW AND SHORT ANSWER QUESTION ON IMAGE PROCESSING-BIOMEDICAL JOBS & NOTES-QUESTION NO 1-20

Define Image?
An image may be defined as two dimensional light intensity function f(x, y)
where x and y denote spatial co-ordinate and the amplitude or value of f at any point
(x, y) is called intensity or grayscale or brightness of the image at that point.

## Something about Shoulder replacement surgery

Image via Wikipedia

Joint replacement involves surgery to replace the ends of bones in a damaged joint. This surgery creates new joint surfaces.

In shoulder replacement surgery, doctors replace the ends of the damaged upper arm bone (humerus) and usually the shoulder bone (scapula) or cap them with artificial surfaces lined with plastic or metal and plastic. Shoulder joint components may be held in place with cement, or they may be made with material that allows new bone to grow into the joint component over time to hold it in place without cement.

## HOW TO DESIGN A CAREER IN BIOMEDICAL ENGINEERING-FROM IEEE PAPER

ABSTRACT

What kind of career do you imagine for yourself?  Doctor? Lawyer?
Scientist? Engineer? Teacher? CEO? Manager? Salesperson?
A university degree in biomedical engineering will prepare you for
all of these professions and more.  Biomedical engineers use their expert-
ise in biology, medicine, physics, mathematics, engineering science and
communication to make the world a healthier place.   The challenges cre-
ated by the diversity and complexity of living systems require creative,
knowledgeable, and imaginative people working in teams of physicians,
scientists, engineers, and even business folk to monitor, restore and
enhance normal body function.  The biomedical engineer is ideally
trained to work at the intersection of science, medicine and mathematics
to solve biological and medical problems.
