WHY QA PROGRAM
1
ACR Statements
Every
patient with cancer deserves to
receive the best possible management to
achieve cure, long-term tumor control or
palliation
Every patient comes for diagnosis
deserves to receive the correct diagnosis
with minimum side effect from radiation to
get a accurate, earlier detection of disease
JCAHO Views
JCAHO states:
There shall be quality control policies and
procedures governing nuclear medicine activities
that assure diagnostic and therapeutic reliability
and safety of patients and personnel
JCAHO requires that QA in radiation field be a
part of the hospital’
hospital’s QA program, and more
recently, that a program of Continuous Quality
Improvement (CQI) be implemented
2
ALARA Principle
Radiation
equipment is a great device for
diagnosis and treatment, however, the
nature of radiation may cause radiationinduced side effects to the patients
ALARA Principle is an essential guideline
for radiation applications
Cost-Effectiveness Views
Cost effectiveness is also an important issue for
radiation medicines under nowadays medical
environment
To control the exponential growth of imagingimagingrelated expenditures, the US government and
third party have implemented “PayPay-forforPerformance (P4P)”
(P4P)”
ACR held a conference “ P4P: Translating Quality
into Economic and Success”
Success” to discuss the
strategies for implementing quality program
including patient safety, interpretation

How QA PROGRAM
Work
Team Work
The comprehensive Quality Management
program has clinical,
clinical, physical,
physical, and administrative
components and its implementation requires the
team work of all personnel
The physician,
physician, physicist,
physicist, and technologist along
with other member of the team should
collaborate on developing a written QA program
for Quality Management program
4
Mechanism
The QA program details the quality control tests
and procedures,
procedures, their frequency,
frequency, the action
criteria,
criteria, the records required and the personnel
required to perform them
The QA program should have a QA committee
and include a feedback mechanism to that
committee so that the cause of any shortcomings
can be addressed and corrected promptly and
properly
General Guidelines
Periodic
check the performance
Checked with “qualified” instruments
Performed with “qualified” personnel
Followed detail procedures
Guided by a updated policy manual
Followed a report and action channel
Run by a comprehensive QA program
Aim for goal CQI

What Is QA PROGRAM
Looking For
Issues To Be Addressed
Machines
function properly?
All measurements within the tolerance?
All parameters within the specification?
Any actions needed to be addressed
Meet ALARA criteria?
Meet the Federal/State regulation?
Meet the clinical standard?
Are patients and staffs safe?

What Should QA Program Cover?
To
assure the positive answers to the
above questions, the QA program should
cover the following major areas:
a. Safety
b. Mechanical
c. Dosimetry
d. Image quality
