  1. b) Background:


Most of my study is focused on how laser therapy can be used to treat broken bones. It is important for bones to heal through their own normal processes. Based on what we know, the time it takes to heal from a fracture is much longer. I have tried various methodsfor helping my broken bone heal faster and more comfortably. In recent years, there has been a lot of interest in using LASER therapy to treat broken bones. There are many different things that affect how long it takes for a broken bone to heal. Even in the most cutting-edge medical practices of the modern age, plaster casts are still an important part of treating broken bones. Also, injuries are often treated with screw plates these days. Using these ways to treat a broken bone takes a longer amount of time. Recent studies, on the other hand, have shown that laser treatment is the best way to fix broken bones.


I have been instructed by my supervisor to perform various duties while executing the project. I have been asked to design the laser circuit by initially forming a block diagram. After this, I was asked to perform the experiment of healing the bone fracture by surgery using guinea pigs. After the surgery had been done, I was asked to collect the samples of laser irradiation on the guinea pig. After this, the guinea pigs were euthanized and the radiographic images were collected. Furthermore, bone extraction had been done with the help of a vet surgeon after collecting radiography images with the help of an Xray.

  1. Background

[CE 2.2]

LVAD, or the Left Ventricular Assist Device, is a mechanism that helps to enhance the heart performance. It is comprised primarily of rotary pumps that are lighter, smaller, and quieter as compared to the pulsatile pumps. The development of an appropriate feedback helps in controlling the speed of pump and is required to meet the crucial challenges. In this study, I have performed the practical issues that are connected to the controller development. The controller performance helps in noise measurement to investigate the flow of pump signal.

[CE 2.6]

During the project implementation, I completed some crucial responsibilities which are properly given below

  • To gather initial and vital information related to the microcontroller, flow sensor, and power source through different articles, books, and journals
  • I had drafted a particular methodology for my project supervisor regarding the nature of the overall design
  • I had properly collected the required materials and methods for designing and developing the LVAD device. 
  • I had properly communicated with my other teammates and with my project supervisor as well.
  • I had adequately updated the project progress report with my project supervisor and discussed every aspect regarding the LVAD device.



  1. Introduction

[CE 3.1]

Dates:January 2018

Duration: January to March 2018

Location: Butwal, Lumbini Province, Nepal

Name of the organization: Butwal CT and Imagining Private Limited

Position Title: Team Leader

  1. Background

[CE3.2] Nature of the project

The nature of this project was developing clear images regarding the structure inside of a body by utilizing massive radio waves and a large magnet alongside a computer. MRI system is to properly implemented, monitor, and diagnose numerous medical criteria. However, the MRI system does not utilize radiation techniques or X-rays rather it utilizes a massive magnet and radio waves to develop a clear image of structures and organs inside a human's body. The scanner of the MRI system primarily utilizes powerful radio waves and magnetic fields in order to produce signals through the body. Those signals are then picked up through the radio antenna beside processed through a computer for developing a detailed image. 

[CE3.3] Objective

The objective of this project was to adequately install the 0.3T permanent magnet MRI system.

At the beginning of this project, the gantry units and related accessories had been offloaded for the further installation process. After that, I positioned that gantry unit by the guidance of Hitachi Medical technical team. A proper wiring of both the MR unit to the filter box and the gantry unit to the filter box done has been done after this.

[CE3.6] Statement of duties

In this project, I had to work on the installation of a 0.3T permanent magnet MRI system. I performed different kinds of responsibilities regarding fieldwork support.

My main responsibilities in this project have been properly elaborated below

  • I assisted in the precise installation of upgraded MRI systems, besides delivering different comprehensive applications for ensuring smooth operation.
  • I had to provide support for rectifying and identifying fails in the MRI system
  • I had to properly maintain all the documentation in the all-on service that is provided to the customers, for ensuring a perfect record.
